MOBPP01	PLCverif Re-engineered: An Open Platform for the Formal Analysis of PLC Programs	PLC, controls, target, interface	21
	E. Blanco Viñuela, D. Darvas CERN, Geneva, Switzerland V. Molnár BUTE, Budapest, Hungary
	Programmable Logic Controllers (PLC) are widely used for industrial automation in industry and at CERN. The reliability of PLC software is crucial, but typically only testing is used to validate it. Our work targets the use of formal verification in practical ways for many years, which showed that it can be beneficial and practically applicable to various PLC programs. In this paper, we present PLCverif, our platform for formal analysis of PLC programs which has largely enhanced the quality of the deployed PLC software. By re-engineering the previous internal prototype tool, we built PLCverif to be an open, extensible platform that can be used not only for CERN’s specific PLC programs. PLCverif is licensed under an open source license, allowing the interested parties to use and extend it.

MOBPP04	The ELT M1 Local Control Software: From Requirements to Implementation	controls, network, PLC, GUI	38
	L. Andolfato, J. Argomedo, C. Diaz Cano, R. Frahm, T.R. Grudzien, N. Kornweibel, D. Ribeiro Gomes dos Santos, J. Sagatowski ESO, Garching bei Muenchen, Germany C.M. Silva CSW, Coimbra, Portugal
	This paper presents the ELT M1 Local Control Software. M1 is the 39 m primary mirror of the Extremely Large Telescope composed of 798 hexagonal segments. Each segment can be controlled in piston, tip, and tilt, and provides several types of sensor data, totaling 24000 I/O points. The control algorithm, used to dynamically maintain the alignment and the shape of the mirror, is based on three pipelined stages dedicated to collect the sensors’ measurements, compute new references, and apply them to the actuators. Each stage runs at 500 Hz and the network traffic produced by devices and servers is close to 1.2 million UDP packets/s. The reliability of this large number of devices is improved by the introduction of a failure detection isolation and recovery SW component. The paper summarizes the main SW requirements, presents the architecture based on a variation of the estimator/controller/adapter design pattern, and provides details on the implementation technologies, including the SW platform and the application framework. The lessons learned from deploying the SW on CPUs with different NUMA architectures and from the adoption of different testing strategies are also described.

MOBPP06	20 Years of World Class Telescope Control Systems Evolution	controls, hardware, interface, EPICS	52
	T.D. Gaggstatter, I. Arriagada, P.E. Gigoux, R. Rojas Gemini Observatory, Southern Operations Center, La Serena, Chile J. Molgo GMTO Corporation, Pasadena, USA F. Ramos Grantecan S.A., Center for Astrophysics in La Palma, Brena Baja, Spain
	This paper analyzes the evolution of control systems for astronomical telescopes. For this comparison we look through the lens of three world class telescopes: Gemini, GTC and GMT. The first two have been in operations for twenty and ten years respectively, whilst the latter is currently under construction. With a planned lifetime of 50+ years, obsolescence management is a common issue among these facilities. For the telescopes currently under operation, their real-time distributed control systems were engineered using state-of-the-art software and hardware available at the time of their design and construction. GMT and newer telescopes are no different in this regard, but are aiming to capitalize on the experiences of the previous generations so they can be better prepared to support their operations. We highlight the differences and common aspects of their software and hardware infrastructure (operating systems, middleware, user interfaces), the pros and cons of each choice and what has been done and what is being planned for obsolescence management.

MOCPL01	IBEX: Beamline Control at ISIS Pulsed Neutron and Muon Source	controls, neutron, EPICS, experiment	59
	K.V.L. Baker, F.A. Akeroyd, D.P. Keymer, T. Löhnert, C. Moreton-Smith, D.E. Oram STFC/RAL/ISIS, Chilton, Didcot, Oxon, United Kingdom J.R. Holt, T.A. Willemsen, K. Woods Tessella, Abingdon, United Kingdom
	For most of its over 30 years of operation the ISIS Neutron and Muon Source has been using bespoke control software on its beamlines. In the last few years, we have been converting the beamline control software to IBEX, which is based on the Open Source EPICS toolkit. More than half the instruments at ISIS are now converted. IBEX must be robust and flexible enough to allow instrument scientists to perform the many experiments they can conceive of. Using EPICS as a base, we have built Python services and scripting support as well as developing an Eclipse/RCP GUI based on Control System Studio*. We use an Agile based development methodology with heavy use of automated testing and device emulators. As we move to the final implementation stage, we are handling new instrument challenges (such as reflectometry) and providing new functionality (live neutron data view, script generator and server). This presentation will cover an overview of the IBEX architecture, our development practices, what is currently in progress, and our future plans. J. Phys. Conf.

MOCPL02	Modernization of Experimental Data Taking at BESSY II	controls, experiment, EPICS, framework	65
	R. Müller, A.F. Balzer, P. Baumgärtel, G. Hartmann, O.-P. Sauer, J. Viefhaus HZB, Berlin, Germany
	The modernization approach for the automation of experimental data taking at BESSY II will be based on the data model of devices. Control of new components and refactoring and reassembly of legacy software should fit into a device based framework. This approach guides the integration of motors, encoders, detectors and auxiliary subsystems. In addition modern software stacks are enabled to provide automation tools for beamline and experimental flow control and DAQ. Strategic goal is the mapping of real beamline components into modelling software to provide the corresponding digital twin. First tests applying DMA methods within this context for tuning are promising.

MOCPL04	Software Architecture for Automatic LHC Collimator Alignment Using Machine Learning	alignment, controls, operation, collimation	78
	G. Azzopardi, S. Redaelli, B. Salvachua CERN, Meyrin, Switzerland A. Muscat, G. Valentino University of Malta, Information and Communication Technology, Msida, Malta
	The Large Hadron Collider at CERN relies on a collimation system to absorb unavoidable beam losses before they reach the superconducting magnets. The collimators are positioned close to the beam in a transverse setting hierarchy achieved by aligning each collimator with a precision of a few tens of micrometers. In previous years, collimator alignments were performed semi-automatically, requiring collimation experts to be present to oversee and control the entire process. In 2018, manual, expert control of the alignment procedure was replaced by dedicated machine learning algorithms, and this new software was used for collimator alignments throughout the year. This paper gives an overview of the software re-design required to achieve fully automatic collimator alignments, describing in detail the software architecture and controls systems involved. Following this successful deployment, this software will be used in the future as the default alignment software for the LHC. G. Valentino et al., "Semi-automatic beam-based LHC collimator alignment", Physical Review Special Topics-Accelerators and Beams vol. 15, no. 5, 2012.

MOCPR01	Graduate Software Engineer Development Program at Diamond Light Source	controls, experiment, detector, hardware	97
	A.A. Wilson, T.M. Cobb, U.K. Pedersen DLS, Oxfordshire, United Kingdom
	Diamond Light Source is the UK’s synchrotron facility. The support and development of the beamlines and accelerators at Diamond requires a significant quantity of specific knowledge and skills; the opportunity to acquire these beforehand is not available to many early in their career. This limits the field of candidates who can begin working independently at the level of software systems engineer. The graduate software engineer development program was started in 2015 to provide a route for engineers who are recent graduates or new to the field to develop the required skills and experience. Over the course of two years it comprises a series of projects in different groups, mentored on-the-job training and organized training courses. The program has recently been expanded to cover all groups in the Scientific Software, Controls and Computation department at Diamond, with an intake of four new engineers per year. This paper presents the structure and development of the program and invites discussion with other organizations to share knowledge and experience.

MOCPR02	The EPICS Collaboration Turns 30	EPICS, controls, toolkit, interface	101
	L.R. Dalesio Osprey DCS LLC, Ocean City, USA A.N. Johnson ANL, Lemont, Illinois, USA K.-U. Kasemir ORNL, Oak Ridge, Tennessee, USA
	At a time when virtually all accelerator control systems were custom developments for each individual laboratory, an idea emerged from a meeting between the Los Alamos National Laboratory developers of the Ground Test Accelerator Control System and those tasked to design the control system for the Advanced Photon Source at Argonne National Laboratory. In a joint effort, the GTACS toolkit concept morphed into the beginnings of a powerful toolkit for building control systems for scientific facilities. From this humble beginning the Experimental Physics and Industrial Control System (EPICS) Collaboration quickly grew. EPICS is now used as a framework for control systems for scientific facilities on seven continents. The EPICS Collaboration started from a dedicated group of developers with very different ideas. This software continues to meet the increasingly challenging requirements for new facilities. This paper is a retrospective look at the creation and evolution of a collaboration that has grown for thirty years, with a look ahead to the future.

	Funding: INAF Osservatorio Astronomico d’Abruzzo The Square Kilometre Array (SKA) project is an international effort to build two radio interferometers in South Africa and Australia to form one observatory monitored and controlled from the global headquarters (GHQ) in the United Kingdom. The project is very close to the end of its design phase and many decisions have already been made like the adoption of the Tango-controls framework. The time from the end of the design phases and the beginning of the construction has been called bridging with the goal of promoting CI-CD practices. CI-CD is an acronym for Continuous integration (CI) and continuous delivery and/or continuous deployment. CI is the practice of merging all developers’ local (working) copies into the mainline very often (at least daily). Continuous delivery is the approach of developing software in short cycle ensuring that it can be released anytime, and continuous deployment is the approach of delivering the software frequently and automatically. The present paper analyzes the decision taken by the system team (a specialized agile team for continuous practices in the Safe framework) for promoting those practices within the Tango-controls framework.

MOMPL001	Quality Assurance Plan for the SCADA System of the Cherenkov Telescope Array Observatory	controls, data-acquisition, operation, target	121
	E. Antolini CTA, Heidelberg, Germany D. Melkumyan, K. Mosshammer, I. Oya DESY Zeuthen, Zeuthen, Germany
	The Cherenkov Telescope Array is the future ground-based facility for gamma-ray astronomy at very-high energies. The CTA Observatory will comprise more than 100 telescopes and calibration devices that need to be centrally managed and synchronized to perform the required scientific and technical activities. The operation of the array requires a complex Supervisory Control and Data Acquisition (SCADA) system, named Array Control and Data Acquisition (ACADA), whose quality level is crucial for maximizing the efficiency of the CTA operations. In this contribution we aim to present the Quality Assurance (QA) strategy adopted by the ACADA team to fulfill the quality standards required for the creation and usage of ACADA software. We will describe the QA organization and planned activities, together with the quality models and the related metrics defined to comply with the required quality standards. We will describe the procedures, methods and tools which will be applied in order to guarantee, that for each phase of the project, the required level of quality in the design, implementation, testing, integration, configuration, usage and maintenance of the ACADA product are met.

	Funding: Work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DE-SC0000661 Development of many software projects at the Facility of Rare Isotope Beams (FRIB) follows an agile development approach. An important part of this practice is to make new software versions available to users frequently to meet their changing needs during commissioning and to get feedback from them in a timely manner. However, building, testing, packaging, and deploying software manually can be a time-consuming and error-prone process. We will present processes and tools used at FRIB to standardize and automate the required steps. We will also describe our experience upgrading control system computers to a new operating system version as well as to a new EPICS release.

MOMPL007	The Design of Intelligent Integrated Control Software Framework of Facilities for Scientific Experiments	controls, framework, monitoring, experiment	132
	Z. Ni, L. Li, J. Liu, J. Luo, X. Zhou CAEP, Sichuan, People’s Republic of China Y. Gao Stony Brook University, Stony Brook, New York, USA
	The control system of the scientific experimental facility requires heterogeneous control access, domain algorithm, sequence control, monitoring, log, alarm and archiving. We must extract common requirements such as monitoring, control, and data acquisition. Based on the Tango framework, we build typical device components, algorithms, sequence engines, graphical models and data models for scientific experimental facility control systems developed to meet common needs, and are named the Intelligent integrated Control Software Framework of Facilities for Scientific Experiments (iCOFFEE). As a development platform for integrated control system software, iCOFFEE provides a highly flexible architecture, standardized templates, basic functional components and services for control systems that increase flexibility, robustness, scalability and maintainability. This article focuses on the design of the framework, especially the monitoring configuration and control flow design.

MOMPR003	Data Visualization With Data Browser Software	framework, TANGO, EPICS, controls	155
	K. Saintin CEA-IRFU, Gif-sur-Yvette, France R. Girardot SOLEIL, Gif-sur-Yvette, France
	Scientific facilities need to visualize a large amount of data through several dedicated applications. They can monitor variables from a PLC, visualize data acquisition or browse them offline. Thus, an intuitive GUI is necessary to handle multiple data sources. In 2012, SOLEIL computing team started the Data browser development. It uses modular and extendable frameworks on which several institutes collaborated: - CDMA (Common Data Model Access) initiated by ANSTO and maintained by SOLEIL developers, unifies the access to data regardless of its physical container (files, databases) or its logical organization. - COMETE (COMmunity of Extendable Toolkit for Experiment) framework, initiated by SOLEIL, provides data visualization widgets and unifies the way there are connected to the data regardless of its source. Since then, SOLEIL developed several plugins for Data browser: HDF/Nexus, Tango**. Recently, IRFU control software team decided to use this software for EPICS*** data and to collaborate with SOLEIL. Data browser integrates new EPICS plugins: Channel Access, Archiver Appliance.

	Agile Project Management (Agile PM), coupled with the DevOps concept, has been worked out as a fundamental approach in a highly uncertain and unpredictable environment to achieve mature software development and to efficiently support concurrent operation. At the European XFEL, Agile PM and DevOps have been applied to provide adaptability and efficiency in the development and operation of its control system: Karabo. In this context, the Control and Analysis Software Group (CAS) has developed in-house a management platform composed of the following macro-artefacts: (1) Agile Process; (2) Release Planning; (3) Testing Infrastructure; (4) Roll-out and Deployment Strategy; (5) Automated tools for Monitoring Control Points (i.e. Configuration Items) and; (6) Incident Management**. The software engineering management platform is also integrated with User Relationship Management to establish and maintain a proper feedback loop with our scientists who set up the requirements. This article aims to briefly describe the above points and show how agile project management has guided the software strategy, development and operation of the Karabo control system at the European XFEL.

	Time-resolved pump-probe experiments at SOLEIL Synchrotron (France) have motivated the development of a new and fast photon counting camera prototype. The core of the camera is a hybrid pixel detector, based on the UFXC32k readout chips bump-bonded to a silicon sensor. This detector exhibits promising performances with very fast readout time, high dynamic range, extended count rate linearity and optimized X-ray detection in the energy range 5-15 keV. In close collaboration with CRISTAL beamline, SOLEIL’s Detector, Electronics and Software Groups carried out a common R&D project to design and realize a 2-chips camera prototype with a high-speed data acquisition system. The system has been fully integrated into Tango and Lima data acquisition framework used at SOLEIL. The development and first experimental results will be presented in this paper.

MOMPR006	Performance of the ALICE Luminosity Leveling Software Architecture in the Pb-Pb Physics Run	luminosity, proton, operation, experiment	167
	G. Valentino University of Malta, Information and Communication Technology, Msida, Malta G. De Cataldo, M. Hostettler CERN, Geneva, Switzerland A. Franco INFN-Bari, Bari, Italy O.B. Visnyei KFKI, Budapest, Hungary
	Luminosity leveling is performed in the ALICE experiment of the Large Hadron Collider (LHC) in order to limit the event pile-up probability, and ensure a safe operation for the detectors. It will be even more important during Run 3 when 50 KHz Pb ion-Pb ion (Pb-Pb) collisions will be delivered in IP2. On the ALICE side, it is handled by the ALICE-LHC Interface project, which also ensures an online data exchange between ALICE and the LHC. An automated luminosity leveling algorithm was developed for the proton-proton physics run, and was also deployed for the Pb-Pb run with some minor changes following experience gained. The algorithm is implemented in the SIMATIC WinCC SCADA environment, and determines the leveling step from measured beam parameters received from the LHC, and the luminosity recorded by ALICE. In this paper, the software architecture of the luminosity leveling software is presented, and the performance achieved during the Pb-Pb run and Van der Meer scans is discussed.

MOMPR007	Scalable High Demand Analytics Environments with Heterogeneous Clouds	data-analysis, experiment, scattering, operation	171
	K. Woods, R.J. Clegg, R. Millward Tessella, Abingdon, United Kingdom F. Barnsely, C. Jones STFC/RAL, Chilton, Didcot, Oxon, United Kingdom
	Funding: UK Research and Innovation - Science & Technology Facilities Council (UK SBS IT18160) The Ada Lovelace Centre (ALC) at STFC provides on-demand, data analysis, interpretation and analytics services to scientists using UK research facilities. ALC and Tessella have built software systems to scale analysis environments to handle peaks and troughs in demand as well as to reduce latency by provision environments closer to scientists around the world. The systems can automatically provision infrastructure and supporting systems within compute resources around the world and in different cloud types (including commercial providers). The system then uses analytics to dynamically provision and configure virtual machines in various locations ahead of demand so that users experience as little delay as possible. In this poster, we report on the architecture and complex software engineering used to automatically scale analysis environments to heterogeneous clouds, make them secure and easy to use. We then discuss how analytics was used to create intelligent systems in order to allow a relatively small team to focus on innovation rather than operations.

	Funding: Horizon2020 Marie Skłodowska-Curie Grant Agreement No 675265 The Italian National Hadrontherapy Center (CNAO) is a particle treatment and research center equipped with a synchrotron accelerator. The configuration and support environment of CNAO’s control system, originally designed in 2003, is currently being upgraded to incorporate mobile devices. As part of the technological upgrade, a product line architecture has been designed with intent to define application scope, reusability of core assets, and specification of variation points. Implementation and compliance with the product line architecture aims at reducing application’s development time, improving reliability, and aiding medical certification procedures. However, definition and compliance with the architecture comes with considerable overhead development costs. In order to assist the development of new environment applications, a visual wizard has been developed to create customized base applications. This paper presents the challenges encountered and description of the product line architecture for the upgraded configuration and support environment. Alongside, we also describe the Wizard Generator, currently implemented applications, and planned application validation.

MOPHA003	Integrating Mobile Devices Into CNAO’s Control System, a Web Service Approach to Device Communication	controls, interface, SCADA, framework	192
	C.F. Afonso, L. Casalegno, S. Foglio, S.G. Gioia, M. Necchi, S. Toncelli CNAO Foundation, Pavia, Italy C. Larizza Pavia University, Biomedical Informatics Lab "Mario Stefanelli", Pavia, Italy
	Funding: Horizon2020 Marie Skłodowska-Curie Grant Agreement No 675265 The Italian National Hadrontherapy Center (CNAO) is a cancer treatment center employing a synchrotron to accelerate charged particle beams. The configuration and support environment of CNAO’s control system is responsible for managing the repository, configuring the control system, as well as performing non-real time support operations. Applications in this environment interface with the relational repository, remote file systems, as well as lower level control system components. As part of the technological upgrade of the configuration and support environment, CNAO plans to integrate mobile applications into the control system. In order to lay the groundwork for the new generation of applications, new communication interfaces had to be designed. To achieve this, a web services approach was taken, with the objective of standardizing access to these resources. In this paper we describe in detail the update of the communication channels. Additionally, several solutions to challenges encountered, such as access management, logging, and interoperability, are presented.

MOPHA010	Automatic Beam Loss Threshold Selection for LHC Collimator Alignment	alignment, collimation, beam-losses, detector	208
	G. Azzopardi, S. Redaelli, B. Salvachua CERN, Meyrin, Switzerland A. Muscat, G. Valentino University of Malta, Information and Communication Technology, Msida, Malta
	The collimation system used in the Large Hadron Collider at CERN is positioned around the beam with a hierarchy that protects sensitive equipment from unavoidable beam losses. The collimator settings are determined using a beam-based alignment technique, where collimator jaws are moved towards the beam until the beam losses exceed a predefined threshold. This threshold needs to be updated dynamically, corresponding to the changes in the beam losses. The current method for aligning collimators is semi-automated requiring a collimation expert to monitor the loss signals and continuously select and update the threshold accordingly. The human element in this procedure is a major bottleneck for speeding up the alignment. This paper therefore proposes a method to fully automate this threshold selection. A data set was formed from previous alignment campaigns and analyzed to define an algorithm that produced results consistent with the user selections. In over 90% of the cases the difference between the two was negligible and the algorithm presented in this study was used for collimator alignments throughout 2018.

MOPHA014	Building and Packaging EPICS Modules With Conda	EPICS, Linux, factory, Windows	223
	B. Bertrand, A. Harrisson ESS, Lund, Sweden
	Conda is an open source package, dependency and environment management system. It runs on Windows, macOS and Linux and can package and distribute software for any language (Python, R, Ruby, C/C++…). It allows one to build a software in a clean and repeatable way. EPICS is made of many different modules that need to be compiled together. Conda makes it easy to define and track dependencies between EPICS base and the different modules (and their versions). Anaconda’s new compilers allow conda to build binaries that can run on any modern linux distribution (x86₆4). Not relying on any specific OS packages removes issues that can arise when upgrading the OS. At ESS, conda packages are built using gitlab-ci and pushed to a local channel on our Artifactory server. Using conda makes it easy for the users to install the EPICS modules they want, where they want (locally on a machine, in a docker container for testing…). All dependencies and requirements are handled by conda. Conda environments make it possible to work on different versions on the same machine without any conflict.

MOPHA019	Upgrade of the Control System for the LHC High Level RF	controls, PLC, interface, cavity	236
	Y. Brischetto, L. Arnaudon, V. Costa, D.C. Glenat, D. Landré CERN, Meyrin, Switzerland
	The acceleration of particles in CERN’s Large Hadron Collider (LHC) is carried out by sixteen superconducting radiofrequency (RF) cavities. Their remote control is taken care of by a complex system which involves heterogeneous equipment and interfaces with a number of different subsystems, such as high voltage power converters, cryogenics, vacuum and access control interlocks. In view of the renovations of the CERN control system planned for the Long Shutdown 2 (LS2), the control software for the RF system recently underwent a complete bottom-up refactoring, in order to dispose of obsolete software and ensure the operation of the system in the long term. The upgraded software has been deployed one year before LS2, and allowed successful operation of the machine. This paper describes the strategy followed in order to commission the system and to guarantee LHC nominal operation after LS2.

	The FORS Upgrade project (FORS-Up), financed by the European Southern Observatory, aims at upgrading the FORS2 instrument currently installed on the UT1 telescope of the ESO Very Large Telescope in Chile. FORS2 is an optical instrument that can be operated in different modes (imaging, polarimetry, long-slit and multi-object spectroscopy). Due to its versatility, the ESO Scientific Technical Committee has identified FORS2 as a highly demanded workhorse among the VLT instruments that shall remain operative for the next 15 years. The main goals of the FORS-Up project are the replacement of the FORS2 scientific detector and the upgrade of the instrument control software and electronics. The project is conceived as "fast track" so that FORS2 is upgraded to the VLT for 2022. This paper focuses on the outcomes of the FORS-Up Phase A, ended in February 2019, and carried out as a collaboration between ESO and INAF – Astronomical Observatory of Trieste, this latter in charge of the feasibility study of the upgrade of the control software and electronics with the latest VLT standard technologies (among them the use of the PLCs and of the latest features of the VLT Control Software).

MOPHA030	An Upgrade of the HARPS-N Spectrograph Autoguider at TNG	GUI, controls, target, MMI	258
	R. Cirami, I. Coretti, P. Di Marcantonio INAF-OAT, Trieste, Italy F. Alesina, N. Buchschacher, F. Pepe Université de Genève, Observatoire Astronomique, Versoix, Switzerland
	HARPS-N is a high-precision radial-velocity spectrograph installed on the INAF TNG in the island of La Palma, Canary Islands. The HARPS-N project is a collaboration among several institutes lead by the Astronomical Observatory of the University of Geneva. The HARPS-N control software is composed by the Sequencer, which coordinates the scientific observations and by a series of modules implemented in LabVIEW for the control of the instrument front end, calibration unit and autoguider. The autoguider is the subsystem in charge of maintaining the target centered on the spectrograph fiber. It acquires target images at high frequency with a technical CDD and with the help of dedicated algorithms keeps the target centered on the fiber through a piezo tip-tilt stage. Exploiting the expertise acquired with the autoguiding system of the ESPRESSO spectrograph installed at the ESO VLT, a collaboration has been setup between the HARPS-N Consortium and the INAF - Astronomical Observatory of Trieste for the design and implementation of a new autoguider for HARPS-N. This paper describes the design, implementation and installation phases of the new autoguider system.

	Funding: This work was partially supported by the ASTRI "Flagship Project" financed by the Italian Ministry of Education, University, and Research and led by the Italian National Institute of Astrophysics. Large volumes of technical and logging data result from the operation of large scale astrophysical infrastructures. In the last few years several "Big Data" technologies have been developed to deal with a huge amount of data, e.g. in the Internet of Things (IoT) framework. We are comparing different stacks of Big Data/IoT architectures including high performance distributed messaging systems, time series databases, streaming systems, interactive data visualization. The main aim is to classify these technologies based on a set of use cases typically related to the data produced in the astronomical environment, with the objective to have a system that can be updated, maintained and customized with a minimal programming effort. We present the preliminary results obtained, using different Big Data stack solution to manage some use cases related to quasi real-time collection, processing and storage of the technical data, logging and technical alert produced by the array of nine ASTRI telescopes that are under development by INAF as a pathfinder array for the Cherenkov astronomy in the TeV energy range.

MOPHA033	Timing, Synchronization and Software-Generated Beam Control at FRIB	timing, network, hardware, controls	272
	E. Daykin, M.G. Konrad FRIB, East Lansing, Michigan, USA
	Funding: Work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DE-SC0000661 The Facility for Rare Isotope Beams, once completed, will require hundreds of devices throughout the machine to operate using synchronized timestamps and triggering events. These include, but are not limited to fault timestamps, time-dependent diagnostic measurements and complex beam pulse patterns. To achieve this design goal, we utilize a timing network using off-the-shelf hardware from Micro Research Finland. A GPS time base is also utilized to provide client timestamping synchronization via NTP/PTP. We describe our methods for software-generated event and beam pulse patterns, performance of installed equipment against project requirements, integration with other systems and challenges encountered during development.

MOPHA042	Evaluating VISTA and EPICS With Regard to Future Control Systems Development at ISIS	controls, EPICS, hardware, database	291
	I.D. Finch STFC/RAL/ISIS, Chilton, Didcot, Oxon, United Kingdom
	The ISIS Muon and Neutron Source has been in operation for more than 30 years and has already seen one complete replacement of its controls system software. Currently ISIS uses the Vista controls system suite of software. I present our work in implementing a new EPICS control system for our Front End Test Stand (FETS) currently running VISTA. This new EPICS system is being used to evaluate a possible migration from Vista to EPICS at a larger scale in ISIS. I present my experience in the initial implementation of EPICS, considerations on using a phased transition during which the two systems are run in parallel, and our future plans with regard to developing control systems in an established decades-old accelerator with heterogeneous systems.

MOPHA046	A New Simulation Timing System for Software Testing in Collider-Accelerator Control Systems	timing, controls, simulation, booster	307
	Y. Gao, T.G. Robertazzi Stony Brook University, Stony Brook, New York, USA K.A. Brown, M. Harvey, J. Morris, R.H. Olsen BNL, Upton, New York, USA
	Particle accelerators need a timing mechanism to properly accelerate the beam from its source to its destination. The synchronization among accelerator devices is important, which is accomplished by a distribution of timing signals. Devices which require their times synchronized to the acceleration cycle are connected to timelines. Timing signals are sent out along the timelines in the form of digital codes. Correspondingly, devices in the complex are equipped with timeline decoders, which allow devices to extract timing signals appropriately. In this work, a new simulation architecture is introduced which can generate user-specific timing events for software testing in the control systems.

	The Experimental Areas group of the CERN Engineering department operates a number of beamlines for the fixed target experiments, irradiation facilities and test beams. The software currently used for the simulation of the beamline layout (BEATCH), beam optics (TRANSPORT), particle tracking (TURTLE) and muon halo calculation (HALO) has been developed in FORTRAN in the 1980s and requires an update in order to ensure long-term continuity. The ongoing Software Migration Project transfers the beamline description to a set of newer commonly used software codes, such as MADX, FLUKA, G4Beamline, BDSIM etc. This contribution summarizes the goals and the scope of the project. It discusses the implementation of the beamlines in the new codes, their integration into the CERN layout database and the interfaces to the software codes used by other CERN groups. This includes the CERN secondary beamlines control system CESAR, which is used for the readout of the beam diagnostics and control of the beam via setting of the magnets, collimators, filters etc. The proposed interface is designed to allow a comparison between the measured beam parameters and the ones calculated with beam optics software.

	Funding: This project has received funding from the European Union’s Horizon 2020 Research and Innovation program under Grant Agreement no. 654168. The Proton Irradiation Facility (IRRAD) is a reference facility at CERN for characterizing detectors and other accelerator components against radiation. To ensure reliable facility operations and smooth experimental data handling, a new IRRAD Data Manager (IDM) web application has been developed and first used during the last facility run before the CERN Long Shutdown 2. Following best practices in User Experience design, IDM provides a user-friendly interface that allows both users to handle their samples’ data and the facility operators to manage and coordinate the experiments more efficiently. Based on the latest web technologies such as Django, JQuery and Semantic UI, IDM is characterized by its minimalistic design and functional robustness. In this paper, we present the key features of IDM, our design choices and its overall software architecture. Moreover, we discuss scalability and portability opportunities for IDM in order to cope with the requirements of other irradiation facilities.

	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-SC0012704 with the U.S. Department of Energy. The fast extraction kicker system at AGS to RHIC transport line uses Stanford Research DG535 delay generators to time, synchronize, and trigger charging power supplies and high-level thyratron trigger pulse generators. This timing system has been upgraded to use an SRS DG645 instrument due to reliability issues with the aforementioned model and slow response time of GPIB buses. The new model provides the relative timing of the separate kicker modules of the assembly from a synchronized external trigger with the RF system. Specifications of the timing scheme, an algorithm to load settings synchronized with RHIC real-time events, and performance analysis of the software will be presented in the paper.

MOPHA078	Renovation of the SPS Personnel Protection System: A Configurable Approach	site, controls, PLC, operation	395
	T. Ladzinski, B. Fernández Adiego, F. Havart CERN, Meyrin, Switzerland
	The renovation of the SPS Personnel Protection System (PPS) comprises the installation of industrial access control solutions and the implementation of a new safety instrumented system tailored to the particular needs of the accelerator. The SPS has been a working horse of the CERN accelerator complex for many decades and its configuration has changed through the many years of operation. The classic solutions for safety systems design, used in the LHC and PS machines, have not been judged adequate for this accelerator undergoing perpetual changes, composed of many sites forming several safety chains. In order to avoid expensive software modifications, each time the accelerator configuration evolves, a configurable safety software design was proposed. This paper presents the hardware architecture of the PLC-based SPS PPS and the configurable software architecture proposed. It further reports on the testing and formal verification activities performed to validate the safety software and discusses the pros and cons of the configurable approach.

MOPHA085	CERN Controls Open Source Monitoring System	monitoring, controls, status, database	404
	F. Locci, F. Ehm, L. Gallerani, J. Lauener, J.P. Palluel, R. Voirin CERN, Meyrin, Switzerland
	The CERN accelerator controls infrastructure spans several thousands of machines and devices used for Accelerator control and data acquisition. In 2009 a full home-made CERN solution has been developed (DIAMON) to monitor and diagnose the complete controls infrastructure. The adoption of the solution by an enlarged community of users and its rapid expansion led to a final product that became more difficult to operate and maintain, in particular because of the multiplicity and redundancy of the services, the centralized management of the data acquisition and visualization software, the complex configuration and also the intrinsic scalability limits. At the end 2017, a complete new monitoring system for the beam controls infrastructure was launched. The new "COSMOS" system was developed with two main objectives in mind: First, detect instabilities and prevent breakdowns of the control system infrastructure and to provide users with a more coherent and efficient solution for the development of their specific data monitoring agents and related dashboards. This paper describes the overall architecture of COSMOS, focusing on the conceptual and technological choices of the system.

CTA will consist of two large arrays with 118 Cherenkov telescopes in total, deployed in Paranal (Chile) and Roque de Los Muchachos Observatories (Canary Islands, Spain). The Array Control and Data Acquisition (ACADA) system provides the means to execute observations and to handle the acquisition of scientific data in CTA. The Resource Manager & Central Control (RM&CC) sub-system is a core element in the ACADA system. It implements the execution of observation requests received from the scheduler sub-system and provides infrastructure services concerning the administration of various resources to all ACADA sub-systems. The RM&CC is also responsible of the dynamic allocation and management of concurrent operations of up to nine telescope sub-arrays, which are logical groupings of individual CTA telescopes performing coordinated scientific operations. This contribution presents a summary of the main RM&CC design features, and of the future plans for prototyping.

	The SPES* Tape Station (STS) for Radioactive Ion Beams (RIBs) characterization is under construction at LNL. This tool will be used to measure the actual composition of the radioactive ion beams extracted from the SPES-β ion source and to optimize the source’s parameters. STS will provide beam diagnostic information by determining the beam composition and intensity. At the same time, it will be able to measure the target release curves needed for the source’s characterization and development. The core part of the system, the related motor and controls are being designed and constructed in synergy with IPN Orsay (France), iThemba Laboratories (South Africa) and the Gamma collaboration (INFN-CSN3). In particular, the mechanical part is based on the existing BEDO tape system operated in ALTO while the control system for motion is an EPICS* base application under implementation by iThemba and INFN, result of a upgrade operation required to substitute obsoleted hardware and update logic and algorithm. https://web.infn.it/spes/ Etil et al.

MOPHA098	A New Communication Interface for the European Southern Observatory (ESO)’s Very Large Telescope Technical Detector Control System Using Aravis, an Open-Source Library for GenICam Cameras	interface, controls, detector, Ethernet	444
	K.F. Mulholland OSL, St Ives, Cambridgeshire, United Kingdom J. Knudstrup, F. Pellegrin ESO, Garching bei Muenchen, Germany
	The European Southern Observatory’s Very Large Telescope (VLT) provides support for high-performance industrial cameras with its Technical Detector Control System (TDCS). Until now, TDCS has used a communication interface based on an API from Allied Vision Technologies (AVT), which only supports cameras made by AVT. As part of the VLT 2019 release, a new communication interface has been developed for TDCS using Aravis, the open-source library for GenICam cameras. Aravis has been independently developed to provide support for cameras from any vendor, although this is not guaranteed. It reads the GenICam interface of a GigE Vision camera to enable control. It also has capabilities for USB3Vision cameras. With this new communication interface, support for other manufacturers is now possible. It has been tested with cameras from AVT and Basler, and further tests using a CameraLink camera with a GigE Vision adapter are planned. This paper will discuss the capabilities of Aravis, considerations in the design of the communication interface, and lessons learnt from the implementation.

	U.M. Neuman, J.D. O’Hea DLS, Oxfordshire, United Kingdom I.H. Rey Tessella, Abingdon, United Kingdom K. Ward Mind Foundry Ltd, Oxford, United Kingdom
	Macromolecular Crystallography (MX) facilities are known for using many samples and require software tools which can scan, store and help to track samples’ Data Matrix codes and to maintain the correct sample processing order. An open source Data Matrix code scanning program, Puck Scanner, developed at Diamond Light Source (DLS) is introduced, its scanning algorithm explained and the continuous visualisation of results presented. Scanned codes are stored together with date, time, and the number of valid codes within a puck. This information is crucial for researchers as it allows them to match the sample with X-ray scanning results. The software is used in Diamond’s XChem laboratory on a day to day basis and has started to be adopted by other facilities.

MOPHA100	quasar : The Full-Stack Solution for Creation of OPC-UA Middleware	controls, embedded, SCADA, detector	453
	P.P. Nikiel, P. Moschovakos, S. Schlenker CERN, Meyrin, Switzerland
	Quasar (Quick OPC-UA Server Generation Framework) enables efficient development of OPC-UA servers. The project evolved into a software ecosystem providing complete OPC-UA support for Detector Control Systems. OPC-UA servers can be modeled and generated and profit from tooling to aid development, deployment and maintenance. OPC-UA client libraries can be generated and published to users. Client-server chaining is supported. quasar was used to build OPC-UA servers for different computing platforms including server machines, credit-card computers as well as System-on-a-chip solutions. Quasar generated servers can be integrated as slave modules into other software projects written in higher-level programming languages (such as Python) to provide OPC-UA information exchange. quasar supports quick and efficient integration of OPC-UA servers into a control system based on the WinCC OA SCADA platform. The ecosystem can work with different OPC-UA stacks including 100% free and open-source ones. Thus it’s not restricted by licensing constraints. The contribution will present an overview and the evolution of the ecosystem along with example applications from ATLAS DCS and beyond.

MOPHA105	Adaptation of CERN Power Converter Controls for Integration into Other Laboratories using EPICS and TANGO	controls, EPICS, TANGO, hardware	462
	S.T. Page, J. Afonso, C. Ghabrous Larrea, J. Herttuainen, Q. King, B. Todd CERN, Geneva, Switzerland
	Modern power converters (power supplies) at CERN use proprietary controls hardware, which is integrated into the wider control system by software device servers developed specifically for the CERN environment, built using CERN libraries and communication protocols. There is a growing need to allow other HEP laboratories to make use of power converters that were originally developed for CERN and, consequently, a desire to allow for their efficient integration into control systems used at those laboratories, which are generally based upon either of the EPICS and Tango frameworks. This paper gives an overview of power converter equipment and software currently being provided to other laboratories through CERN’s Knowledge and Technology Transfer program and describes differences identified between CERN’s control system model and that of EPICS, which needed to be accounted for. A reference EPICS implementation provided by CERN to other laboratories to facilitate integration of the CERN power converter controls is detailed and the prospects for the development of a Tango equivalent in the future are also covered.

MOPHA106	FGC3.2: A New Generation of Embedded Controls Computer for Power Converters at CERN	controls, embedded, Linux, hardware	468
	S.T. Page, C. Ghabrous Larrea, Q. King, B. Todd, S. Uznanski, D.J. Zielinski CERN, Geneva, Switzerland
	Modern power converters (power supplies) at CERN are controlled by devices known as Function Generator/Controllers (FGCs), which are embedded computer systems providing function generation, current and field regulation, and state control. FGCs were originally conceived for the LHC in the early 2000s, though later generations are now increasingly being deployed in the accelerators in the LHC Injector Chain (Linac4, Booster, Proton Synchrotron and SPS) to replace obsolete equipment. A new generation of FGC known as the FGC3.2 is currently in development, which will provide for the evolving needs of the CERN accelerator complex and additionally be supplied to other HEP laboratories through CERN’s Knowledge and Technology Transfer program. This paper describes the evolution of FGCs, summarizes tests performed to evaluate candidate components for the FGC3.2 and details the final hardware and software architectures which were chosen. The new controller will make use of a multi-core ARM-based system-on-chip (SoC) running an embedded Linux operating system in contrast to earlier generations which combined a microcontroller and DSP with software running on ’bare metal’.

	The Detector Control System (DCS) is one of the main pieces involved in the operation of the Compact Muon Solenoid (CMS) experiment at the LHC. The system is built using WinCC Open Architecture (WinCC OA) and the Joint Controls Project (JCOP) framework which was developed on top of WinCC at CERN. Following the JCOP paradigm, CMS has developed its own framework which is structured as a collection of more than 200 individual installable components each providing a different feature. Everyone of the systems that the CMS DCS consists of is created by installing a different set of these components. By automating this process, we are able to quickly and efficiently create new systems in production or recreate problematic ones, but also, to create development environments that are identical to the production ones. This latter one results in smoother development and integration processes, as the new/reworked components are developed and tested in production-like environments. Moreover, it allows the central DCS support team to easily reproduce systems that the users/developers report as being problematic, reducing the response time for bug fixing and improving the support quality.

MOPHA113	Linux-based PXIe System for the Real-Time Control of New Painting Bumper at CERN	controls, operation, hardware, network	483
	M.P. Pimentel, E. Carlier, C. Chanavat, T. Gharsa, G. Gräwer, N. Magnin, N. Voumard CERN, Geneva, Switzerland
	In the framework of the LHC Injectors Upgrade Project, the new connection from Linac4, injecting a 160 MeV H⁻ beam into the Proton Synchrotron Booster (PSB) requires a set of four slow kicker magnets (KSW) per PSB ring to move the beam on a stripping foil, remove electrons and perform phase space painting. A new multiple-linear waveform generator based on a Marx topology powers each KSW, allowing adjustment of the current discharge shape with high flexibility for the different beam users. To control these complex power generators, National Instruments (NI) PXIe crates fitted with a set of modules (A/D, D/A, FPGA, PROFINET) are used. Initially, control software developed with LabVIEW has validated the test bench hardware. A full software re-engineering, accessing the hardware using Linux drivers, C APIs and the C++ framework FESA3 under Linux CentOS7 was achieved for operational deployment. This paper describes the hardware used, and the integration of NI PXIe systems into CERN controls environment, as well as the software architecture to access the hardware and provide PSB operators and kicker experts with the required control and supervision.

MOPHA115	Code Generation Tools and Editor for Memory Maps	hardware, interface, GUI, Linux	493
	P. Plutecki, B. Bielawski, A.C. Butterworth CERN, Geneva, Switzerland
	Cheburashka, a toolset created in the Radio Frequency Group at CERN, has become an essential part of our hardware and software developments. Due to changing requirements, this toolset has been recently rewritten in C++ and Python. A hardware developer, using the graphical editor, defines a memory map, which is subsequently used to ensure consistency between software and hardware. The memory map file is an input for a variety of tools used by the hardware engineers, such as VHDL code generators. In addition to aiding the firmware development, our tools generate C++ wrapper libraries. The wrapper provides a simple interface on top of a Linux device driver to read and write registers by exposing memory map nodes in a hierarchical way, performing all low-level bit manipulations and checks internally. To interact with the hardware, a software that runs on a front-end computer is needed. Cheburashka allows us to generate FESA (Front-End Software Architecture) classes with parts of the operational interface already present. This paper describes the evolution of the graphical editor and the Python tools used for C++ code generation, along with a description of their main features.

Núñez Pardo de Vera DESY, Hamburg, Germany
	Users visiting scientific installations aim to collect the best quality data frequently under time pressure. They look for complementary techniques at different sites and when they arrive to one they have limited time to understand the data acquisition architecture. In these conditions, the availability of generic and common interfaces to the experimental channels and measurements improve the user experience regarding the programming and configuration of the experiment. Here we present solutions to the data acquisition challenges provided by the Sardana scientific SCADA suite. In one experimental session the same detector may be employed in different modes e.g., getting the data stream when aligning the sample or the stage, getting a single time/monitor controlled exposure and finally running the measurement process like a step or continuous scan. The complexity of the acquisition setup increases with the number of detectors being simultaneously used and even more depending on the applied synchronization. In this work we present recently enriched Sardana interfaces and optimized processes and conclude with the roadmap of further enhancements.

	MAX IV Laboratory, inaugurated in June 2016, has for the last 8 months accepted synchrotron users on three beamlines, NanoMAX, BioMAX and Hippie, while simultaneously pushing towards bringing more beamlines into the commissioning and user phases. As evidence of this, the last call issued addressed 10 beamlines. As of summer 2019, MAX IV has reached a point where 11 beamlines simultaneously have shutters open and are thus receiving light under stable operation. With 16 beamlines funded, the number of beamlines will grow over the coming years. The Controls and IT group has performed numerous beamline system installations such as a sample changer at BioMAX, Dectris detector at Nanomax, and End Station at Hippie. It has additionally developed processes, such as automated IT infrastructure with a view to accepting users. We foresee a focus on end stations and detectors, as well as data storage, data handling and scientific software. As an example, a project entitled "DataStaMP" has been recently funded aiming to increase the data and metadata storage and management system in order to accommodate the ever increasing demand for storage and access.

MOPHA145	Evolution of the CERN LINAC 4 Intensity Interlock System Using a Generic, Real-Time Comparator in C++	linac, injection, MMI, hardware	570
	A. Topaloudis, J.C. Allica Santamaria CERN, Geneva, Switzerland
	During the commissioning phase of LINAC 4, three watchdog interlock systems were used to protect the accelerator and its equipment. These systems cut the beam if losses, calculated by combining the intensity measurements at various locations, exceed some predefined thresholds. While the existing systems were designed to be simple and robust to ensure safety, the future connection of the linac to the Proton Synchrotron Booster (PSB) requires new instances of these systems with additional requirements. Such requirements include the remote communication of the watchdogs with the intensity measurement systems to decouple any physical dependency between the two systems, and the arithmetical/logical combination of the measured data based on the watchdog location. As the Controls Interlocks Beam User (CIBU) hardware interface to the Beam Interlock Controller (BIC) is simple, the software part of the system can be re-designed to be application agnostic giving a single decision after performing a configurable set of comparisons. This paper describes the upgrade of the software of the existing watchdog interlock system to a generic comparator, enabling its usage for other applications.

MOPHA147	Integrating the First SKA MPI Dish Into the MeerKAT Array	TANGO, controls, interface, monitoring	575
	S.N. Twum, A.F. Joubert, K. Madisa SARAO, Cape Town, South Africa
	Funding: National Research Foundation The 64-antenna MeerKAT interferometric radio telescope is a precursor to the SKA which will host hundreds of receptor dishes with a collecting area of 1 sq km. During the pre-construction phase of the SKA1 MID, the SKA DSH Consortium plans to build, integrate and qualify an SKA1 MID DSH Qualification Model (SDQM) against MeerKAT. Before the system level qualification testing can start on the SDQM, the qualified Dish sub-elements have to be integrated onto the SDQM and set to work. The SKA MPI DISH, a prototype SKA dish funded by the Max Planck Institute, will be used for early verification of the hardware and the control system. This prototype dish uses the TANGO framework for monitoring and control while MeerKAT uses the Karoo Array Telescope Control Protocol (KATCP). To aid the integration of the SKA MPI DSH, the MeerKAT Control and Monitoring (CAM) subsystem has been upgraded by incorporating a translation layer and a specialized SKA antenna proxy that will enable CAM to monitor and command the SKA dish as if it were a MeerKAT antenna.

MOPHA149	Accelerator Schedule Management at CERN	controls, operation, status, database	579
	B. Urbaniec, C. Roderick CERN, Geneva, Switzerland
	Maximizing the efficiency of operating CERN’s accelerator complex requires careful forward planning, and synchronized scheduling of cross-accelerator events. These schedules are of interest to many people helping them to plan and organize their work. Therefore, this data should be easily accessible, both interactively and programmatically. Development of the Accelerator Schedule Management (ASM) system started in 2017 to address such topics and enable definition, management and publication of schedule data in generic way. The ASM system currently includes three core modules to manage: Yearly accelerator schedules for the CERN Injector complex and LHC; Submission and scheduling of Machine Development (MD) requests with supporting statistics; Submission, approval, scheduling and follow-up of control system changes and their impact. This paper describes the ASM Web application (built with Angular, TypeScript and Java) in terms of: Core scheduling functionality; Integration of external data sources; Provision of programmatic access to schedule data via a language agnostic REST API (allowing other systems to leverage schedule data).

MOPHA153	SoC Technology for Embedded Control and Interlocking Within Fast Pulsed Systems at CERN	controls, hardware, FPGA, real-time	592
	P. Van Trappen, E. Carlier, M. Gauthier, N. Magnin, E.J. Oltedal, J. Schipper CERN, Geneva, Switzerland
	The control of pulsed systems at CERN requires often the use of fast digital electronics to perform tight timing control and fast protection of high-voltage pulsed generators. For the implementation of such functionalities, a FPGA is the perfect candidate for the digital logic, however with limited integration potential within the control system. The market push for integrated devices, so called System on a Chip (SoC) - a tightly coupled ARM processing system and specific programmable logic in a single device, has allowed a better integration of the various components required for the control of pulsed systems. This technology is used for the implementation of fast switch interlocking logic, integrated within the CERN control framework by using embedded Linux running a Snap7 server. It is also used for the implementation of a lower-tier communication bridge between a front-end computer and a high fan-out multiplexing programmable logic for timing and analogue low-level control. This paper presents these two projects where the SoC technology has been deployed and discusses possible further applications within distributed real-time control architecture for distributed pulsed systems.

MOPHA154	Data Acquisition System Deployment Using Docker Containers for the SMuRF Project	EPICS, timing, hardware, network	597
	J.A. Vásquez SLAC, Menlo Park, California, USA
	The SLAC Microresonator Radio Frequency (SMuRF) system is being developed as a readout system for next generation Cosmic Microwave Background (CMB) cameras. It is based on a FPGA board where the real-time digital processing algorithms are implemented, and high-level applications running in an industrial PC. The software for this project is based on C++ and Python and it is in active development. The software follows the client-server model where the server implements the low-level communication with the FGPA while high-level applications and data processing algorithms run on the client. SMuRF systems are being deployed in several institutions and in order to facilitate the management of the software application releases, dockers containers are being used. Docker images, for both servers and clients, contain all the software packages and configurations needed for their use. The images are tested, tagged, and published in one place. They can then be deployed in all other institutions in minutes with no extra dependencies. This paper describes how the docker images are designed and build, and how continuous integration tools are used in their release cycle for this project. arXiv:1809.03689 [astro-ph.IM]

MOPHA156	The Linux Device Driver Framework for High-Throughput Lossless Data Streaming Applications	Linux, interface, neutron, FPGA	602
	K. Vodopivec, J.E. Breeding ORNL, Oak Ridge, Tennessee, USA J.W. Sinclair ORNL RAD, Oak Ridge, Tennessee, USA
	Funding: This work was supported by the U.S. Department of Energy under contract DE-AC0500OR22725. Many applications in experimental physics facilities require custom hardware solutions to control process parameters or to acquire data at high rates with high integrity. These hardware solutions typically require custom software implementations. The neutron scattering detectors at the Spallation Neutron Source at ORNL* implement custom protocols over optical fiber connected to a PCI express based read-out board. A dedicated kernel device driver provides an interface to the software application and must be able to sustain data bursts from a pulsed source while acquiring data for long periods of time. The same optical channel is also used as low-latency communication link to detector electronics for configuration and real time fault detection. This paper presents a Linux device driver design, implementation challenges in a low-latency high-throughput setup, real use case benchmarks and importance of clean application programming interface for seamless integration in control systems. This software implementation was developed as a generic framework and has been extended beyond neutron data acquisition. It is suitable to diverse applications where it allows for rapid FPGA development. *Oak Ridge National Laboratory

	C.H. Wang, C.P. Chu IHEP, Beijing, People’s Republic of China H.H. Lv SINAP, Shanghai, People’s Republic of China
	HEPS is a big complex science facility which consists of the accelerator, the beam lines and general facilities. The accelerator is made up of many subsystem and a large number of components such as magnets, power supply, high frequency and vacuum equipment, etc. Variety of components and equipment with cables are distributed installation with distance to each other. These components during the stage of the design and construction and commissioning will produce tens of thousands of data. The information collection and storage and management for so much data for a large scientific device is particularly important. This paper describes the HEPS database design and application from the construction and installation and put into operations generated by the uniqueness of huge amounts of data, in order to fully improve the availability and stability of the accelerator, and experiment stations, and further improve the overall performance.

MOPHA164	Wire Scanner for High Intensity Beam Profile Diagnostics	controls, data-acquisition, electron, EPICS	622
	J. Yan, J. Gubeli, K. Jordan JLab, Newport News, Virginia, USA B. Bailey University of Tennessee, Knoxville, USA
	A control and data acquisition system of a high speed wire scanner is developed for high intensity beam profile diagnostics. The control system of the wire scanner includes two IOCs, a Soft IOC and a VME IOC. The Soft IOC connects with an Aerotech Ensemble motor drive through EPCIS motor record and controls the movement of the wire scanner. An Electrical Input card samples the real-time position of the wire through an incremental encoder, and generates a pulse to synchronize a VME ADC data acquisition card, which digitizes and samples the beam-induced signal after pre-amplification. A VME Relay Output card is installed to control the Brake Solenoid and Actuator Solenoid. All the VME I/O cards are installed on one VME crate and controlled by the VME IOC. The system configuration and software of the wire scanner are under development. Authored by Jefferson Science Associates, LLC under U.S. DOE Contract No. DE-AC05-06OR23177.

	Funding: Work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DESC0000661 To facilitate software development for the high-level applications on the particle accelerator, we proposed and prototyped a computing platform, so-called ’phyapps-cloud’. Based on the technology stack composed by Python, JavaScript, Docker, and Web service, such a system could greatly decouple deployment and development. That is, the users (app developers) only need to focus on the feature development by working on the infrastructure that is served by ’phyapps-cloud’, while the cloud service provider (which develop and deploy ’phyapps-cloud’) could focus on the development of the infrastructure. In this contribution, the development details will be addressed, as well as the demonstration of a simple Python script development on this platform.

MOPHA173	Graphical User Interface Programming Challenges Moving Beyond Java Swing and JavaFX	GUI, interface, hardware, framework	637
	S. Bart Pedersen, S. Jackson CERN, Geneva, Switzerland
	Oracle, the owner of Java, announced in 2018 that they would stop supporting their Swing and JavaFX technologies within the next decade. These technologies have fulfilled the graphical user interface (GUI) needs of CERN accelerator operation for over 2 decades, but their impending eradication has triggered an initiative to choose alternative technologies to develop future GUIs. Hundreds of existing applications will also need to be migrated or rewritten. The challenges to replace Java GUIs are numerous. The programmers will have to adapt and be retrained. The performance of the new GUI technologies will have to be at least as performant as the existing Java technologies. The programming environment, code versioning, dependency management and documentation will all need to be considered. This paper provides an overview of research comparing candidate GUI technologies and explains the selection of two main language families as possible replacements for Swing and JavaFX: Web applications (combining Java/JavaScript and web sockets) and Python PyQt (C++ based graphical library).

MOSH4001	A Library of Fundamental Building Blocks for Experimental Control Software	experiment, controls, interface, FEL	653
	M. Scarcia, R. Borghes, M. Lonza, M. Manfredda, R. Mincigrucci, E. Pedersoli Elettra-Sincrotrone Trieste S.C.p.A., Basovizza, Italy
	In many experimental facilities there is a rising interest by users and beamline scientists to take part in the experiment control software development process. This necessity arises from the flexibility and adaptability of many beamlines, that can run very different experiments, requiring changes in the software even during beamtimes. On the other side, we still need a professional and controlled approach in order to be able to maintain the software efficiently. Our proposed solution is to exploit the object oriented nature of programming languages to create a library that provides a uniform interface both to the different controlled devices (e.g. motors) and to experimental procedures (e.g. scans). Every component and procedure can be represented as an object, a building block for experiment control scripts. We can thus provide the scientists with a powerful tool for implementing highly flexible control software to run experiments. Furthermore, a library makes the development of experiment control scripts easier and quicker for software developers. In any case we are able to protect the most sensitive structures (e.g. control systems) beneath a strong and trusted software layer.

Programmable Logic Controllers (PLC) are widely used for industrial automation in industry and at CERN. The reliability of PLC software is crucial, but typically only testing is used to validate it. Our work targets the use of formal verification in practical ways for many years, which showed that it can be beneficial and practically applicable to various PLC programs. In this paper, we present PLCverif, our platform for formal analysis of PLC programs which has largely enhanced the quality of the deployed PLC software. By re-engineering the previous internal prototype tool, we built PLCverif to be an open, extensible platform that can be used not only for CERN’s specific PLC programs. PLCverif is licensed under an open source license, allowing the interested parties to use and extend it.

This paper presents the ELT M1 Local Control Software. M1 is the 39 m primary mirror of the Extremely Large Telescope composed of 798 hexagonal segments. Each segment can be controlled in piston, tip, and tilt, and provides several types of sensor data, totaling 24000 I/O points. The control algorithm, used to dynamically maintain the alignment and the shape of the mirror, is based on three pipelined stages dedicated to collect the sensors’ measurements, compute new references, and apply them to the actuators. Each stage runs at 500 Hz and the network traffic produced by devices and servers is close to 1.2 million UDP packets/s. The reliability of this large number of devices is improved by the introduction of a failure detection isolation and recovery SW component. The paper summarizes the main SW requirements, presents the architecture based on a variation of the estimator/controller/adapter design pattern, and provides details on the implementation technologies, including the SW platform and the application framework. The lessons learned from deploying the SW on CPUs with different NUMA architectures and from the adoption of different testing strategies are also described.

This paper analyzes the evolution of control systems for astronomical telescopes. For this comparison we look through the lens of three world class telescopes: Gemini, GTC and GMT. The first two have been in operations for twenty and ten years respectively, whilst the latter is currently under construction. With a planned lifetime of 50+ years, obsolescence management is a common issue among these facilities. For the telescopes currently under operation, their real-time distributed control systems were engineered using state-of-the-art software and hardware available at the time of their design and construction. GMT and newer telescopes are no different in this regard, but are aiming to capitalize on the experiences of the previous generations so they can be better prepared to support their operations. We highlight the differences and common aspects of their software and hardware infrastructure (operating systems, middleware, user interfaces), the pros and cons of each choice and what has been done and what is being planned for obsolescence management.

For most of its over 30 years of operation the ISIS Neutron and Muon Source has been using bespoke control software on its beamlines. In the last few years, we have been converting the beamline control software to IBEX*, which is based on the Open Source EPICS toolkit**. More than half the instruments at ISIS are now converted. IBEX must be robust and flexible enough to allow instrument scientists to perform the many experiments they can conceive of. Using EPICS as a base, we have built Python services and scripting support as well as developing an Eclipse/RCP GUI based on Control System Studio***. We use an Agile based development methodology with heavy use of automated testing and device emulators. As we move to the final implementation stage, we are handling new instrument challenges (such as reflectometry) and providing new functionality (live neutron data view, script generator and server). This presentation will cover an overview of the IBEX architecture, our development practices, what is currently in progress, and our future plans.

HZB, Berlin, Germany

The modernization approach for the automation of experimental data taking at BESSY II will be based on the data model of devices. Control of new components and refactoring and reassembly of legacy software should fit into a device based framework. This approach guides the integration of motors, encoders, detectors and auxiliary subsystems. In addition modern software stacks are enabled to provide automation tools for beamline and experimental flow control and DAQ. Strategic goal is the mapping of real beamline components into modelling software to provide the corresponding digital twin. First tests applying DMA methods within this context for tuning are promising.

CERN, Meyrin, Switzerland

University of Malta, Information and Communication Technology, Msida, Malta

The Large Hadron Collider at CERN relies on a collimation system to absorb unavoidable beam losses before they reach the superconducting magnets. The collimators are positioned close to the beam in a transverse setting hierarchy achieved by aligning each collimator with a precision of a few tens of micrometers. In previous years, collimator alignments were performed semi-automatically*, requiring collimation experts to be present to oversee and control the entire process. In 2018, manual, expert control of the alignment procedure was replaced by dedicated machine learning algorithms, and this new software was used for collimator alignments throughout the year. This paper gives an overview of the software re-design required to achieve fully automatic collimator alignments, describing in detail the software architecture and controls systems involved. Following this successful deployment, this software will be used in the future as the default alignment software for the LHC.

Diamond Light Source is the UK’s synchrotron facility. The support and development of the beamlines and accelerators at Diamond requires a significant quantity of specific knowledge and skills; the opportunity to acquire these beforehand is not available to many early in their career. This limits the field of candidates who can begin working independently at the level of software systems engineer. The graduate software engineer development program was started in 2015 to provide a route for engineers who are recent graduates or new to the field to develop the required skills and experience. Over the course of two years it comprises a series of projects in different groups, mentored on-the-job training and organized training courses. The program has recently been expanded to cover all groups in the Scientific Software, Controls and Computation department at Diamond, with an intake of four new engineers per year. This paper presents the structure and development of the program and invites discussion with other organizations to share knowledge and experience.

At a time when virtually all accelerator control systems were custom developments for each individual laboratory, an idea emerged from a meeting between the Los Alamos National Laboratory developers of the Ground Test Accelerator Control System and those tasked to design the control system for the Advanced Photon Source at Argonne National Laboratory. In a joint effort, the GTACS toolkit concept morphed into the beginnings of a powerful toolkit for building control systems for scientific facilities. From this humble beginning the Experimental Physics and Industrial Control System (EPICS) Collaboration quickly grew. EPICS is now used as a framework for control systems for scientific facilities on seven continents. The EPICS Collaboration started from a dedicated group of developers with very different ideas. This software continues to meet the increasingly challenging requirements for new facilities. This paper is a retrospective look at the creation and evolution of a collaboration that has grown for thirty years, with a look ahead to the future.

The Square Kilometre Array (SKA) project is an international effort to build two radio interferometers in South Africa and Australia to form one observatory monitored and controlled from the global headquarters (GHQ) in the United Kingdom. The project is very close to the end of its design phase and many decisions have already been made like the adoption of the Tango-controls framework. The time from the end of the design phases and the beginning of the construction has been called bridging with the goal of promoting CI-CD practices. CI-CD is an acronym for Continuous integration (CI) and continuous delivery and/or continuous deployment. CI is the practice of merging all developers’ local (working) copies into the mainline very often (at least daily). Continuous delivery is the approach of developing software in short cycle ensuring that it can be released anytime, and continuous deployment is the approach of delivering the software frequently and automatically. The present paper analyzes the decision taken by the system team (a specialized agile team for continuous practices in the Safe framework) for promoting those practices within the Tango-controls framework.

The Cherenkov Telescope Array is the future ground-based facility for gamma-ray astronomy at very-high energies. The CTA Observatory will comprise more than 100 telescopes and calibration devices that need to be centrally managed and synchronized to perform the required scientific and technical activities. The operation of the array requires a complex Supervisory Control and Data Acquisition (SCADA) system, named Array Control and Data Acquisition (ACADA), whose quality level is crucial for maximizing the efficiency of the CTA operations. In this contribution we aim to present the Quality Assurance (QA) strategy adopted by the ACADA team to fulfill the quality standards required for the creation and usage of ACADA software. We will describe the QA organization and planned activities, together with the quality models and the related metrics defined to comply with the required quality standards. We will describe the procedures, methods and tools which will be applied in order to guarantee, that for each phase of the project, the required level of quality in the design, implementation, testing, integration, configuration, usage and maintenance of the ACADA product are met.

Development of many software projects at the Facility of Rare Isotope Beams (FRIB) follows an agile development approach. An important part of this practice is to make new software versions available to users frequently to meet their changing needs during commissioning and to get feedback from them in a timely manner. However, building, testing, packaging, and deploying software manually can be a time-consuming and error-prone process. We will present processes and tools used at FRIB to standardize and automate the required steps. We will also describe our experience upgrading control system computers to a new operating system version as well as to a new EPICS release.

The control system of the scientific experimental facility requires heterogeneous control access, domain algorithm, sequence control, monitoring, log, alarm and archiving. We must extract common requirements such as monitoring, control, and data acquisition. Based on the Tango framework, we build typical device components, algorithms, sequence engines, graphical models and data models for scientific experimental facility control systems developed to meet common needs, and are named the Intelligent integrated Control Software Framework of Facilities for Scientific Experiments (iCOFFEE). As a development platform for integrated control system software, iCOFFEE provides a highly flexible architecture, standardized templates, basic functional components and services for control systems that increase flexibility, robustness, scalability and maintainability. This article focuses on the design of the framework, especially the monitoring configuration and control flow design.

Scientific facilities need to visualize a large amount of data through several dedicated applications. They can monitor variables from a PLC, visualize data acquisition or browse them offline. Thus, an intuitive GUI is necessary to handle multiple data sources. In 2012, SOLEIL** computing team started the Data browser development. It uses modular and extendable frameworks on which several institutes collaborated: - CDMA (Common Data Model Access) initiated by ANSTO**** and maintained by SOLEIL developers, unifies the access to data regardless of its physical container (files, databases) or its logical organization. - COMETE (COMmunity of Extendable Toolkit for Experiment) framework, initiated by SOLEIL, provides data visualization widgets and unifies the way there are connected to the data regardless of its source. Since then, SOLEIL developed several plugins for Data browser: HDF/Nexus, Tango*****. Recently, IRFU* control software team decided to use this software for EPICS*** data and to collaborate with SOLEIL. Data browser integrates new EPICS plugins: Channel Access, Archiver Appliance.

Agile Project Management (Agile PM), coupled with the DevOps concept, has been worked out as a fundamental approach in a highly uncertain and unpredictable environment to achieve mature software development and to efficiently support concurrent operation*. At the European XFEL**, Agile PM and DevOps have been applied to provide adaptability and efficiency in the development and operation of its control system: Karabo***. In this context, the Control and Analysis Software Group (CAS) has developed in-house a management platform composed of the following macro-artefacts: (1) Agile Process; (2) Release Planning; (3) Testing Infrastructure; (4) Roll-out and Deployment Strategy; (5) Automated tools for Monitoring Control Points (i.e. Configuration Items****) and; (6) Incident Management*****. The software engineering management platform is also integrated with User Relationship Management to establish and maintain a proper feedback loop with our scientists who set up the requirements. This article aims to briefly describe the above points and show how agile project management has guided the software strategy, development and operation of the Karabo control system at the European XFEL.

Time-resolved pump-probe experiments at SOLEIL Synchrotron (France) have motivated the development of a new and fast photon counting camera prototype. The core of the camera is a hybrid pixel detector, based on the UFXC32k readout chips bump-bonded to a silicon sensor. This detector exhibits promising performances with very fast readout time, high dynamic range, extended count rate linearity and optimized X-ray detection in the energy range 5-15 keV. In close collaboration with CRISTAL beamline, SOLEIL’s Detector, Electronics and Software Groups carried out a common R&D project to design and realize a 2-chips camera prototype with a high-speed data acquisition system. The system has been fully integrated into Tango and Lima data acquisition framework used at SOLEIL. The development and first experimental results will be presented in this paper.

Luminosity leveling is performed in the ALICE experiment of the Large Hadron Collider (LHC) in order to limit the event pile-up probability, and ensure a safe operation for the detectors. It will be even more important during Run 3 when 50 KHz Pb ion-Pb ion (Pb-Pb) collisions will be delivered in IP2. On the ALICE side, it is handled by the ALICE-LHC Interface project, which also ensures an online data exchange between ALICE and the LHC. An automated luminosity leveling algorithm was developed for the proton-proton physics run, and was also deployed for the Pb-Pb run with some minor changes following experience gained. The algorithm is implemented in the SIMATIC WinCC SCADA environment, and determines the leveling step from measured beam parameters received from the LHC, and the luminosity recorded by ALICE. In this paper, the software architecture of the luminosity leveling software is presented, and the performance achieved during the Pb-Pb run and Van der Meer scans is discussed.

The Ada Lovelace Centre (ALC) at STFC provides on-demand, data analysis, interpretation and analytics services to scientists using UK research facilities. ALC and Tessella have built software systems to scale analysis environments to handle peaks and troughs in demand as well as to reduce latency by provision environments closer to scientists around the world. The systems can automatically provision infrastructure and supporting systems within compute resources around the world and in different cloud types (including commercial providers). The system then uses analytics to dynamically provision and configure virtual machines in various locations ahead of demand so that users experience as little delay as possible. In this poster, we report on the architecture and complex software engineering used to automatically scale analysis environments to heterogeneous clouds, make them secure and easy to use. We then discuss how analytics was used to create intelligent systems in order to allow a relatively small team to focus on innovation rather than operations.

The Italian National Hadrontherapy Center (CNAO) is a particle treatment and research center equipped with a synchrotron accelerator. The configuration and support environment of CNAO’s control system, originally designed in 2003, is currently being upgraded to incorporate mobile devices. As part of the technological upgrade, a product line architecture has been designed with intent to define application scope, reusability of core assets, and specification of variation points. Implementation and compliance with the product line architecture aims at reducing application’s development time, improving reliability, and aiding medical certification procedures. However, definition and compliance with the architecture comes with considerable overhead development costs. In order to assist the development of new environment applications, a visual wizard has been developed to create customized base applications. This paper presents the challenges encountered and description of the product line architecture for the upgraded configuration and support environment. Alongside, we also describe the Wizard Generator, currently implemented applications, and planned application validation.

The Italian National Hadrontherapy Center (CNAO) is a cancer treatment center employing a synchrotron to accelerate charged particle beams. The configuration and support environment of CNAO’s control system is responsible for managing the repository, configuring the control system, as well as performing non-real time support operations. Applications in this environment interface with the relational repository, remote file systems, as well as lower level control system components. As part of the technological upgrade of the configuration and support environment, CNAO plans to integrate mobile applications into the control system. In order to lay the groundwork for the new generation of applications, new communication interfaces had to be designed. To achieve this, a web services approach was taken, with the objective of standardizing access to these resources. In this paper we describe in detail the update of the communication channels. Additionally, several solutions to challenges encountered, such as access management, logging, and interoperability, are presented.

Automatic Beam Loss Threshold Selection for LHC Collimator Alignment

The collimation system used in the Large Hadron Collider at CERN is positioned around the beam with a hierarchy that protects sensitive equipment from unavoidable beam losses. The collimator settings are determined using a beam-based alignment technique, where collimator jaws are moved towards the beam until the beam losses exceed a predefined threshold. This threshold needs to be updated dynamically, corresponding to the changes in the beam losses. The current method for aligning collimators is semi-automated requiring a collimation expert to monitor the loss signals and continuously select and update the threshold accordingly. The human element in this procedure is a major bottleneck for speeding up the alignment. This paper therefore proposes a method to fully automate this threshold selection. A data set was formed from previous alignment campaigns and analyzed to define an algorithm that produced results consistent with the user selections. In over 90% of the cases the difference between the two was negligible and the algorithm presented in this study was used for collimator alignments throughout 2018.

ESS, Lund, Sweden

Conda is an open source package, dependency and environment management system. It runs on Windows, macOS and Linux and can package and distribute software for any language (Python, R, Ruby, C/C++…). It allows one to build a software in a clean and repeatable way. EPICS is made of many different modules that need to be compiled together. Conda makes it easy to define and track dependencies between EPICS base and the different modules (and their versions). Anaconda’s new compilers allow conda to build binaries that can run on any modern linux distribution (x86₆4). Not relying on any specific OS packages removes issues that can arise when upgrading the OS. At ESS, conda packages are built using gitlab-ci and pushed to a local channel on our Artifactory server. Using conda makes it easy for the users to install the EPICS modules they want, where they want (locally on a machine, in a docker container for testing…). All dependencies and requirements are handled by conda. Conda environments make it possible to work on different versions on the same machine without any conflict.

The acceleration of particles in CERN’s Large Hadron Collider (LHC) is carried out by sixteen superconducting radiofrequency (RF) cavities. Their remote control is taken care of by a complex system which involves heterogeneous equipment and interfaces with a number of different subsystems, such as high voltage power converters, cryogenics, vacuum and access control interlocks. In view of the renovations of the CERN control system planned for the Long Shutdown 2 (LS2), the control software for the RF system recently underwent a complete bottom-up refactoring, in order to dispose of obsolete software and ensure the operation of the system in the long term. The upgraded software has been deployed one year before LS2, and allowed successful operation of the machine. This paper describes the strategy followed in order to commission the system and to guarantee LHC nominal operation after LS2.

The FORS Upgrade project (FORS-Up), financed by the European Southern Observatory, aims at upgrading the FORS2 instrument currently installed on the UT1 telescope of the ESO Very Large Telescope in Chile. FORS2 is an optical instrument that can be operated in different modes (imaging, polarimetry, long-slit and multi-object spectroscopy). Due to its versatility, the ESO Scientific Technical Committee has identified FORS2 as a highly demanded workhorse among the VLT instruments that shall remain operative for the next 15 years. The main goals of the FORS-Up project are the replacement of the FORS2 scientific detector and the upgrade of the instrument control software and electronics. The project is conceived as "fast track" so that FORS2 is upgraded to the VLT for 2022. This paper focuses on the outcomes of the FORS-Up Phase A, ended in February 2019, and carried out as a collaboration between ESO and INAF – Astronomical Observatory of Trieste, this latter in charge of the feasibility study of the upgrade of the control software and electronics with the latest VLT standard technologies (among them the use of the PLCs and of the latest features of the VLT Control Software).

HARPS-N is a high-precision radial-velocity spectrograph installed on the INAF TNG in the island of La Palma, Canary Islands. The HARPS-N project is a collaboration among several institutes lead by the Astronomical Observatory of the University of Geneva. The HARPS-N control software is composed by the Sequencer, which coordinates the scientific observations and by a series of modules implemented in LabVIEW for the control of the instrument front end, calibration unit and autoguider. The autoguider is the subsystem in charge of maintaining the target centered on the spectrograph fiber. It acquires target images at high frequency with a technical CDD and with the help of dedicated algorithms keeps the target centered on the fiber through a piezo tip-tilt stage. Exploiting the expertise acquired with the autoguiding system of the ESPRESSO spectrograph installed at the ESO VLT, a collaboration has been setup between the HARPS-N Consortium and the INAF - Astronomical Observatory of Trieste for the design and implementation of a new autoguider for HARPS-N. This paper describes the design, implementation and installation phases of the new autoguider system.

Large volumes of technical and logging data result from the operation of large scale astrophysical infrastructures. In the last few years several "Big Data" technologies have been developed to deal with a huge amount of data, e.g. in the Internet of Things (IoT) framework. We are comparing different stacks of Big Data/IoT architectures including high performance distributed messaging systems, time series databases, streaming systems, interactive data visualization. The main aim is to classify these technologies based on a set of use cases typically related to the data produced in the astronomical environment, with the objective to have a system that can be updated, maintained and customized with a minimal programming effort. We present the preliminary results obtained, using different Big Data stack solution to manage some use cases related to quasi real-time collection, processing and storage of the technical data, logging and technical alert produced by the array of nine ASTRI telescopes that are under development by INAF as a pathfinder array for the Cherenkov astronomy in the TeV energy range.

The Facility for Rare Isotope Beams, once completed, will require hundreds of devices throughout the machine to operate using synchronized timestamps and triggering events. These include, but are not limited to fault timestamps, time-dependent diagnostic measurements and complex beam pulse patterns. To achieve this design goal, we utilize a timing network using off-the-shelf hardware from Micro Research Finland. A GPS time base is also utilized to provide client timestamping synchronization via NTP/PTP. We describe our methods for software-generated event and beam pulse patterns, performance of installed equipment against project requirements, integration with other systems and challenges encountered during development.

The ISIS Muon and Neutron Source has been in operation for more than 30 years and has already seen one complete replacement of its controls system software. Currently ISIS uses the Vista controls system suite of software. I present our work in implementing a new EPICS control system for our Front End Test Stand (FETS) currently running VISTA. This new EPICS system is being used to evaluate a possible migration from Vista to EPICS at a larger scale in ISIS. I present my experience in the initial implementation of EPICS, considerations on using a phased transition during which the two systems are run in parallel, and our future plans with regard to developing control systems in an established decades-old accelerator with heterogeneous systems.

Particle accelerators need a timing mechanism to properly accelerate the beam from its source to its destination. The synchronization among accelerator devices is important, which is accomplished by a distribution of timing signals. Devices which require their times synchronized to the acceleration cycle are connected to timelines. Timing signals are sent out along the timelines in the form of digital codes. Correspondingly, devices in the complex are equipped with timeline decoders, which allow devices to extract timing signals appropriately. In this work, a new simulation architecture is introduced which can generate user-specific timing events for software testing in the control systems.

The Experimental Areas group of the CERN Engineering department operates a number of beamlines for the fixed target experiments, irradiation facilities and test beams. The software currently used for the simulation of the beamline layout (BEATCH), beam optics (TRANSPORT), particle tracking (TURTLE) and muon halo calculation (HALO) has been developed in FORTRAN in the 1980s and requires an update in order to ensure long-term continuity. The ongoing Software Migration Project transfers the beamline description to a set of newer commonly used software codes, such as MADX, FLUKA, G4Beamline, BDSIM etc. This contribution summarizes the goals and the scope of the project. It discusses the implementation of the beamlines in the new codes, their integration into the CERN layout database and the interfaces to the software codes used by other CERN groups. This includes the CERN secondary beamlines control system CESAR, which is used for the readout of the beam diagnostics and control of the beam via setting of the magnets, collimators, filters etc. The proposed interface is designed to allow a comparison between the measured beam parameters and the ones calculated with beam optics software.

The Proton Irradiation Facility (IRRAD) is a reference facility at CERN for characterizing detectors and other accelerator components against radiation. To ensure reliable facility operations and smooth experimental data handling, a new IRRAD Data Manager (IDM) web application has been developed and first used during the last facility run before the CERN Long Shutdown 2. Following best practices in User Experience design, IDM provides a user-friendly interface that allows both users to handle their samples’ data and the facility operators to manage and coordinate the experiments more efficiently. Based on the latest web technologies such as Django, JQuery and Semantic UI, IDM is characterized by its minimalistic design and functional robustness. In this paper, we present the key features of IDM, our design choices and its overall software architecture. Moreover, we discuss scalability and portability opportunities for IDM in order to cope with the requirements of other irradiation facilities.

Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-SC0012704 with the U.S. Department of Energy.
The fast extraction kicker system at AGS to RHIC transport line uses Stanford Research DG535 delay generators to time, synchronize, and trigger charging power supplies and high-level thyratron trigger pulse generators. This timing system has been upgraded to use an SRS DG645 instrument due to reliability issues with the aforementioned model and slow response time of GPIB buses. The new model provides the relative timing of the separate kicker modules of the assembly from a synchronized external trigger with the RF system. Specifications of the timing scheme, an algorithm to load settings synchronized with RHIC real-time events, and performance analysis of the software will be presented in the paper.

CERN, Meyrin, Switzerland

The renovation of the SPS Personnel Protection System (PPS) comprises the installation of industrial access control solutions and the implementation of a new safety instrumented system tailored to the particular needs of the accelerator. The SPS has been a working horse of the CERN accelerator complex for many decades and its configuration has changed through the many years of operation. The classic solutions for safety systems design, used in the LHC and PS machines, have not been judged adequate for this accelerator undergoing perpetual changes, composed of many sites forming several safety chains. In order to avoid expensive software modifications, each time the accelerator configuration evolves, a configurable safety software design was proposed. This paper presents the hardware architecture of the PLC-based SPS PPS and the configurable software architecture proposed. It further reports on the testing and formal verification activities performed to validate the safety software and discusses the pros and cons of the configurable approach.

CERN, Meyrin, Switzerland

The CERN accelerator controls infrastructure spans several thousands of machines and devices used for Accelerator control and data acquisition. In 2009 a full home-made CERN solution has been developed (DIAMON) to monitor and diagnose the complete controls infrastructure. The adoption of the solution by an enlarged community of users and its rapid expansion led to a final product that became more difficult to operate and maintain, in particular because of the multiplicity and redundancy of the services, the centralized management of the data acquisition and visualization software, the complex configuration and also the intrinsic scalability limits. At the end 2017, a complete new monitoring system for the beam controls infrastructure was launched. The new "COSMOS" system was developed with two main objectives in mind: First, detect instabilities and prevent breakdowns of the control system infrastructure and to provide users with a more coherent and efficient solution for the development of their specific data monitoring agents and related dashboards. This paper describes the overall architecture of COSMOS, focusing on the conceptual and technological choices of the system.

The Cherenkov Telescope Array (CTA) will be the next generation ground-based observatory for gamma-ray astronomy at very-high energies. CTA will consist of two large arrays with 118 Cherenkov telescopes in total, deployed in Paranal (Chile) and Roque de Los Muchachos Observatories (Canary Islands, Spain). The Array Control and Data Acquisition (ACADA) system provides the means to execute observations and to handle the acquisition of scientific data in CTA. The Resource Manager & Central Control (RM&CC) sub-system is a core element in the ACADA system. It implements the execution of observation requests received from the scheduler sub-system and provides infrastructure services concerning the administration of various resources to all ACADA sub-systems. The RM&CC is also responsible of the dynamic allocation and management of concurrent operations of up to nine telescope sub-arrays, which are logical groupings of individual CTA telescopes performing coordinated scientific operations. This contribution presents a summary of the main RM&CC design features, and of the future plans for prototyping.

The SPES* Tape Station (STS) for Radioactive Ion Beams (RIBs) characterization is under construction at LNL. This tool will be used to measure the actual composition of the radioactive ion beams extracted from the SPES-β ion source and to optimize the source’s parameters. STS will provide beam diagnostic information by determining the beam composition and intensity. At the same time, it will be able to measure the target release curves needed for the source’s characterization and development. The core part of the system, the related motor and controls are being designed and constructed in synergy with IPN Orsay (France), iThemba Laboratories (South Africa) and the Gamma collaboration (INFN-CSN3). In particular, the mechanical part is based on the existing BEDO** tape system operated in ALTO while the control system for motion is an EPICS*** base application under implementation by iThemba and INFN, result of a upgrade operation required to substitute obsoleted hardware and update logic and algorithm.

The European Southern Observatory’s Very Large Telescope (VLT) provides support for high-performance industrial cameras with its Technical Detector Control System (TDCS). Until now, TDCS has used a communication interface based on an API from Allied Vision Technologies (AVT), which only supports cameras made by AVT. As part of the VLT 2019 release, a new communication interface has been developed for TDCS using Aravis, the open-source library for GenICam cameras. Aravis has been independently developed to provide support for cameras from any vendor, although this is not guaranteed. It reads the GenICam interface of a GigE Vision camera to enable control. It also has capabilities for USB3Vision cameras. With this new communication interface, support for other manufacturers is now possible. It has been tested with cameras from AVT and Basler, and further tests using a CameraLink camera with a GigE Vision adapter are planned. This paper will discuss the capabilities of Aravis, considerations in the design of the communication interface, and lessons learnt from the implementation.

Macromolecular Crystallography (MX) facilities are known for using many samples and require software tools which can scan, store and help to track samples’ Data Matrix codes and to maintain the correct sample processing order. An open source Data Matrix code scanning program, Puck Scanner, developed at Diamond Light Source (DLS) is introduced, its scanning algorithm explained and the continuous visualisation of results presented. Scanned codes are stored together with date, time, and the number of valid codes within a puck. This information is crucial for researchers as it allows them to match the sample with X-ray scanning results. The software is used in Diamond’s XChem laboratory on a day to day basis and has started to be adopted by other facilities.

Quasar (Quick OPC-UA Server Generation Framework) enables efficient development of OPC-UA servers. The project evolved into a software ecosystem providing complete OPC-UA support for Detector Control Systems. OPC-UA servers can be modeled and generated and profit from tooling to aid development, deployment and maintenance. OPC-UA client libraries can be generated and published to users. Client-server chaining is supported. quasar was used to build OPC-UA servers for different computing platforms including server machines, credit-card computers as well as System-on-a-chip solutions. Quasar generated servers can be integrated as slave modules into other software projects written in higher-level programming languages (such as Python) to provide OPC-UA information exchange. quasar supports quick and efficient integration of OPC-UA servers into a control system based on the WinCC OA SCADA platform. The ecosystem can work with different OPC-UA stacks including 100% free and open-source ones. Thus it’s not restricted by licensing constraints. The contribution will present an overview and the evolution of the ecosystem along with example applications from ATLAS DCS and beyond.

Modern power converters (power supplies) at CERN use proprietary controls hardware, which is integrated into the wider control system by software device servers developed specifically for the CERN environment, built using CERN libraries and communication protocols. There is a growing need to allow other HEP laboratories to make use of power converters that were originally developed for CERN and, consequently, a desire to allow for their efficient integration into control systems used at those laboratories, which are generally based upon either of the EPICS and Tango frameworks. This paper gives an overview of power converter equipment and software currently being provided to other laboratories through CERN’s Knowledge and Technology Transfer program and describes differences identified between CERN’s control system model and that of EPICS, which needed to be accounted for. A reference EPICS implementation provided by CERN to other laboratories to facilitate integration of the CERN power converter controls is detailed and the prospects for the development of a Tango equivalent in the future are also covered.

Modern power converters (power supplies) at CERN are controlled by devices known as Function Generator/Controllers (FGCs), which are embedded computer systems providing function generation, current and field regulation, and state control. FGCs were originally conceived for the LHC in the early 2000s, though later generations are now increasingly being deployed in the accelerators in the LHC Injector Chain (Linac4, Booster, Proton Synchrotron and SPS) to replace obsolete equipment. A new generation of FGC known as the FGC3.2 is currently in development, which will provide for the evolving needs of the CERN accelerator complex and additionally be supplied to other HEP laboratories through CERN’s Knowledge and Technology Transfer program. This paper describes the evolution of FGCs, summarizes tests performed to evaluate candidate components for the FGC3.2 and details the final hardware and software architectures which were chosen. The new controller will make use of a multi-core ARM-based system-on-chip (SoC) running an embedded Linux operating system in contrast to earlier generations which combined a microcontroller and DSP with software running on ’bare metal’.

The Detector Control System (DCS) is one of the main pieces involved in the operation of the Compact Muon Solenoid (CMS) experiment at the LHC. The system is built using WinCC Open Architecture (WinCC OA) and the Joint Controls Project (JCOP) framework which was developed on top of WinCC at CERN. Following the JCOP paradigm, CMS has developed its own framework which is structured as a collection of more than 200 individual installable components each providing a different feature. Everyone of the systems that the CMS DCS consists of is created by installing a different set of these components. By automating this process, we are able to quickly and efficiently create new systems in production or recreate problematic ones, but also, to create development environments that are identical to the production ones. This latter one results in smoother development and integration processes, as the new/reworked components are developed and tested in production-like environments. Moreover, it allows the central DCS support team to easily reproduce systems that the users/developers report as being problematic, reducing the response time for bug fixing and improving the support quality.

In the framework of the LHC Injectors Upgrade Project, the new connection from Linac4, injecting a 160 MeV H⁻ beam into the Proton Synchrotron Booster (PSB) requires a set of four slow kicker magnets (KSW) per PSB ring to move the beam on a stripping foil, remove electrons and perform phase space painting. A new multiple-linear waveform generator based on a Marx topology powers each KSW, allowing adjustment of the current discharge shape with high flexibility for the different beam users. To control these complex power generators, National Instruments (NI) PXIe crates fitted with a set of modules (A/D, D/A, FPGA, PROFINET) are used. Initially, control software developed with LabVIEW has validated the test bench hardware. A full software re-engineering, accessing the hardware using Linux drivers, C APIs and the C++ framework FESA3 under Linux CentOS7 was achieved for operational deployment. This paper describes the hardware used, and the integration of NI PXIe systems into CERN controls environment, as well as the software architecture to access the hardware and provide PSB operators and kicker experts with the required control and supervision.

Due to changing requirements, this toolset has been recently rewritten in C++ and Python. A hardware developer, using the graphical editor, defines a memory map, which is subsequently used to ensure consistency between software and hardware. The memory map file is an input for a variety of tools used by the hardware engineers, such as VHDL code generators. In addition to aiding the firmware development, our tools generate C++ wrapper libraries. The wrapper provides a simple interface on top of a Linux device driver to read and write registers by exposing memory map nodes in a hierarchical way, performing all low-level bit manipulations and checks internally. To interact with the hardware, a software that runs on a front-end computer is needed. Cheburashka allows us to generate FESA (Front-End Software Architecture) classes with parts of the operational interface already present. This paper describes the evolution of the graphical editor and the Python tools used for C++ code generation, along with a description of their main features.

Users visiting scientific installations aim to collect the best quality data frequently under time pressure. They look for complementary techniques at different sites and when they arrive to one they have limited time to understand the data acquisition architecture. In these conditions, the availability of generic and common interfaces to the experimental channels and measurements improve the user experience regarding the programming and configuration of the experiment. Here we present solutions to the data acquisition challenges provided by the Sardana scientific SCADA suite. In one experimental session the same detector may be employed in different modes e.g., getting the data stream when aligning the sample or the stage, getting a single time/monitor controlled exposure and finally running the measurement process like a step or continuous scan. The complexity of the acquisition setup increases with the number of detectors being simultaneously used and even more depending on the applied synchronization. In this work we present recently enriched Sardana interfaces and optimized processes and conclude with the roadmap of further enhancements.

MAX IV Laboratory, inaugurated in June 2016, has for the last 8 months accepted synchrotron users on three beamlines, NanoMAX, BioMAX and Hippie, while simultaneously pushing towards bringing more beamlines into the commissioning and user phases. As evidence of this, the last call issued addressed 10 beamlines. As of summer 2019, MAX IV has reached a point where 11 beamlines simultaneously have shutters open and are thus receiving light under stable operation. With 16 beamlines funded, the number of beamlines will grow over the coming years. The Controls and IT group has performed numerous beamline system installations such as a sample changer at BioMAX, Dectris detector at Nanomax, and End Station at Hippie. It has additionally developed processes, such as automated IT infrastructure with a view to accepting users. We foresee a focus on end stations and detectors, as well as data storage, data handling and scientific software. As an example, a project entitled "DataStaMP" has been recently funded aiming to increase the data and metadata storage and management system in order to accommodate the ever increasing demand for storage and access.

Evolution of the CERN LINAC 4 Intensity Interlock System Using a Generic, Real-Time Comparator in C++

A. Topaloudis, J.C. Allica Santamaria
CERN, Geneva, Switzerland

During the commissioning phase of LINAC 4, three watchdog interlock systems were used to protect the accelerator and its equipment. These systems cut the beam if losses, calculated by combining the intensity measurements at various locations, exceed some predefined thresholds. While the existing systems were designed to be simple and robust to ensure safety, the future connection of the linac to the Proton Synchrotron Booster (PSB) requires new instances of these systems with additional requirements. Such requirements include the remote communication of the watchdogs with the intensity measurement systems to decouple any physical dependency between the two systems, and the arithmetical/logical combination of the measured data based on the watchdog location. As the Controls Interlocks Beam User (CIBU) hardware interface to the Beam Interlock Controller (BIC) is simple, the software part of the system can be re-designed to be application agnostic giving a single decision after performing a configurable set of comparisons. This paper describes the upgrade of the software of the existing watchdog interlock system to a generic comparator, enabling its usage for other applications.

Funding: National Research Foundation
The 64-antenna MeerKAT interferometric radio telescope is a precursor to the SKA which will host hundreds of receptor dishes with a collecting area of 1 sq km. During the pre-construction phase of the SKA1 MID, the SKA DSH Consortium plans to build, integrate and qualify an SKA1 MID DSH Qualification Model (SDQM) against MeerKAT. Before the system level qualification testing can start on the SDQM, the qualified Dish sub-elements have to be integrated onto the SDQM and set to work. The SKA MPI DISH, a prototype SKA dish funded by the Max Planck Institute, will be used for early verification of the hardware and the control system. This prototype dish uses the TANGO framework for monitoring and control while MeerKAT uses the Karoo Array Telescope Control Protocol (KATCP). To aid the integration of the SKA MPI DSH, the MeerKAT Control and Monitoring (CAM) subsystem has been upgraded by incorporating a translation layer and a specialized SKA antenna proxy that will enable CAM to monitor and command the SKA dish as if it were a MeerKAT antenna.

CERN, Geneva, Switzerland

Maximizing the efficiency of operating CERN’s accelerator complex requires careful forward planning, and synchronized scheduling of cross-accelerator events. These schedules are of interest to many people helping them to plan and organize their work. Therefore, this data should be easily accessible, both interactively and programmatically. Development of the Accelerator Schedule Management (ASM) system started in 2017 to address such topics and enable definition, management and publication of schedule data in generic way. The ASM system currently includes three core modules to manage: Yearly accelerator schedules for the CERN Injector complex and LHC; Submission and scheduling of Machine Development (MD) requests with supporting statistics; Submission, approval, scheduling and follow-up of control system changes and their impact. This paper describes the ASM Web application (built with Angular, TypeScript and Java) in terms of: Core scheduling functionality; Integration of external data sources; Provision of programmatic access to schedule data via a language agnostic REST API (allowing other systems to leverage schedule data).

CERN, Geneva, Switzerland

The control of pulsed systems at CERN requires often the use of fast digital electronics to perform tight timing control and fast protection of high-voltage pulsed generators. For the implementation of such functionalities, a FPGA is the perfect candidate for the digital logic, however with limited integration potential within the control system. The market push for integrated devices, so called System on a Chip (SoC) - a tightly coupled ARM processing system and specific programmable logic in a single device, has allowed a better integration of the various components required for the control of pulsed systems. This technology is used for the implementation of fast switch interlocking logic, integrated within the CERN control framework by using embedded Linux running a Snap7 server. It is also used for the implementation of a lower-tier communication bridge between a front-end computer and a high fan-out multiplexing programmable logic for timing and analogue low-level control. This paper presents these two projects where the SoC technology has been deployed and discusses possible further applications within distributed real-time control architecture for distributed pulsed systems.

SLAC, Menlo Park, California, USA

The SLAC Microresonator Radio Frequency (SMuRF) system is being developed as a readout system for next generation Cosmic Microwave Background (CMB) cameras*. It is based on a FPGA board where the real-time digital processing algorithms are implemented, and high-level applications running in an industrial PC. The software for this project is based on C++ and Python and it is in active development. The software follows the client-server model where the server implements the low-level communication with the FGPA while high-level applications and data processing algorithms run on the client. SMuRF systems are being deployed in several institutions and in order to facilitate the management of the software application releases, dockers containers are being used. Docker images, for both servers and clients, contain all the software packages and configurations needed for their use. The images are tested, tagged, and published in one place. They can then be deployed in all other institutions in minutes with no extra dependencies. This paper describes how the docker images are designed and build, and how continuous integration tools are used in their release cycle for this project.

Many applications in experimental physics facilities require custom hardware solutions to control process parameters or to acquire data at high rates with high integrity. These hardware solutions typically require custom software implementations. The neutron scattering detectors at the Spallation Neutron Source at ORNL* implement custom protocols over optical fiber connected to a PCI express based read-out board. A dedicated kernel device driver provides an interface to the software application and must be able to sustain data bursts from a pulsed source while acquiring data for long periods of time. The same optical channel is also used as low-latency communication link to detector electronics for configuration and real time fault detection. This paper presents a Linux device driver design, implementation challenges in a low-latency high-throughput setup, real use case benchmarks and importance of clean application programming interface for seamless integration in control systems. This software implementation was developed as a generic framework and has been extended beyond neutron data acquisition. It is suitable to diverse applications where it allows for rapid FPGA development.

A control and data acquisition system of a high speed wire scanner is developed for high intensity beam profile diagnostics. The control system of the wire scanner includes two IOCs, a Soft IOC and a VME IOC. The Soft IOC connects with an Aerotech Ensemble motor drive through EPCIS motor record and controls the movement of the wire scanner. An Electrical Input card samples the real-time position of the wire through an incremental encoder, and generates a pulse to synchronize a VME ADC data acquisition card, which digitizes and samples the beam-induced signal after pre-amplification. A VME Relay Output card is installed to control the Brake Solenoid and Actuator Solenoid. All the VME I/O cards are installed on one VME crate and controlled by the VME IOC. The system configuration and software of the wire scanner are under development.

To facilitate software development for the high-level applications on the particle accelerator, we proposed and prototyped a computing platform, so-called ’phyapps-cloud’. Based on the technology stack composed by Python, JavaScript, Docker, and Web service, such a system could greatly decouple deployment and development. That is, the users (app developers) only need to focus on the feature development by working on the infrastructure that is served by ’phyapps-cloud’, while the cloud service provider (which develop and deploy ’phyapps-cloud’) could focus on the development of the infrastructure. In this contribution, the development details will be addressed, as well as the demonstration of a simple Python script development on this platform.

Graphical User Interface Programming Challenges Moving Beyond Java Swing and JavaFX

GUI, interface, hardware, framework

S. Bart Pedersen, S. Jackson
CERN, Geneva, Switzerland

Oracle, the owner of Java, announced in 2018 that they would stop supporting their Swing and JavaFX technologies within the next decade. These technologies have fulfilled the graphical user interface (GUI) needs of CERN accelerator operation for over 2 decades, but their impending eradication has triggered an initiative to choose alternative technologies to develop future GUIs. Hundreds of existing applications will also need to be migrated or rewritten. The challenges to replace Java GUIs are numerous. The programmers will have to adapt and be retrained. The performance of the new GUI technologies will have to be at least as performant as the existing Java technologies. The programming environment, code versioning, dependency management and documentation will all need to be considered. This paper provides an overview of research comparing candidate GUI technologies and explains the selection of two main language families as possible replacements for Swing and JavaFX: Web applications (combining Java/JavaScript and web sockets) and Python PyQt (C++ based graphical library).

In many experimental facilities there is a rising interest by users and beamline scientists to take part in the experiment control software development process. This necessity arises from the flexibility and adaptability of many beamlines, that can run very different experiments, requiring changes in the software even during beamtimes. On the other side, we still need a professional and controlled approach in order to be able to maintain the software efficiently. Our proposed solution is to exploit the object oriented nature of programming languages to create a library that provides a uniform interface both to the different controlled devices (e.g. motors) and to experimental procedures (e.g. scans). Every component and procedure can be represented as an object, a building block for experiment control scripts. We can thus provide the scientists with a powerful tool for implementing highly flexible control software to run experiments. Furthermore, a library makes the development of experiment control scripts easier and quicker for software developers. In any case we are able to protect the most sensitive structures (e.g. control systems) beneath a strong and trusted software layer.

Continuous Integration (CI) is widely used in industry, especially in the software world. Here we propose a combination of CI processes to run firmware and software tests both in simulation and on real hardware that can be well adapted to FPGA-based accelerator electronics designs. We have built a test rack with a variety of hardware platforms. Relying on source code version control tools, when a developer submits a change to the code base, a multi-stage test pipeline is triggered. Unit tests are run automatically, bitstreams are generated for the various supported FPGA platforms and loaded onto the FPGAs in the rack, and tests are run on hardware. Reports are generated upon test completion and notifications are sent to the developers in case of failure.

An infrastructure for remote access supporting research workflow is essential for neutron scattering user facilities such as J-PARC MLF. Because the experimental period spans day and night, service monitoring the measurement status from outside the facility is required. Additionally, convenient way to bring a large amount of data back to user’s home institution and to analyze it after experiments is required. To meet these requirements, we are developing a remote access infrastructure as a front-end for facility users based on public clouds. Recently, public clouds have been rapidly developed, so that development and operation schemes of computer systems have changed considerably.

Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-SC0012704 with the U.S. Department of Energy
In RHIC low energy bunched beam cooling experiment, LEReC, a 704 MHz fiber laser is modulated such that when striking a photocathode, it produces corresponding electron bunches which are accelerated and transported to overlap an ion beam bunched at 9 MHz RF frequency The need for precise timing is handled well by the existing infrastructure. A layer of software application called the timing manager has been created to track the LEReC beam concerning the RHIC beam and allow instruments to be fired in real-time units instead of bunch timing or RHIC turns. The manager also automates set-tings of different modes based on the RF frequency and maintains the timing of instrumentation with a beam. A detailed description of the bunch structure and scheme of synchronizing the RF and laser pulses will be discussed in the paper.

Funding: This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344 with document release number LLNL-PROC-792238.
LLNL has developed a low latency, real-time, closed-loop, woofer-tweeter Adaptive Optics Control (AOC) system with a feedback control update rate of greater than 16 kHz. The Low-Latency Adaptive Mirror System (LLAMAS) is based on controller software previously developed for the successful Gemini Planet Imager (GPI) instrument which had an update rate of 1 kHz. By tuning the COTS operating system, tuning and upgrading the processing hardware, and adapting existing software, we have the computing power to implement a Linear-Quadratic-Gaussian (LQG) Controller in real time. The implementation of the LQG leverages hardware optimizations developed for low latency computing and the video game industry, such as fused multiply add accelerators and optimized Fast Fourier Transforms. We used the Intel Math Kernel Library (MKL) to implement the high-order LQG controller with a batch mode execution of 576 6x6 matrix multiplies. We will share our progress, lessons learned and our plans to further optimize performance by tuning high order LQG parameters.

CEA, LE BARP cedex, France

The French Laser Megajoule (LMJ) is, behind the US NIF, the second largest inertial fusion facility in the World. The main activity of this facility is the acquisition of several physical phenomena as neutron, gamma, X rays produced by the indirect attack of hundreds of high power laser beams on targets through measurement devices called "target diagnostics". More than 30 diagnostics will be installed and driven in a huge and complex integrated computer control system. All this Targets Diagnostics arrived one at a time, each one with its particularity and complexity. The Tango Architecture and Panorama are used for the command control of these equipment. The aim of this paper is first, to introduce how Targets Diagnostics are progressively integrated in the command control. We will then see how Targets Diagnostics managed to cohabit even if they are in different phases of their integration. The paper concludes how Target Diagnostics are configured and computer-driven during all the shot sequence.

The Linac Coherent Light Source (LCLS) at the SLAC National Accelerator Laboratory is currently undergoing a major upgrade. In order to facilitate the development of new software that will be needed to operate the upgraded machine, a simulator has been developed to simulate the LCLS electron beam and the accelerator devices that measure and manipulate it. The simulator is comprised of several small "services" that simulate different types of devices, and provide an EPICS interface identical to the real control system. All of the services communicate with a central beam line model to change accelerator parameters and retrieve information about the simulated beam.

Jupyter notebooks are executable documents that are displayed in a web browser. The notebook elements consist of human-authored contextual elements and computer code, and computer-generated output from executing the computer code. Such outputs can include tables and plots. The notebook elements can be executed interactively, and the whole notebook can be saved, re-loaded and re-executed, or converted to read-only formats such as HTML, LaTeX and PDF. Exploiting these characteristics, Jupyter notebooks can be used to improve the effectiveness of computational and data exploration, documentation, communication, reproducibility and re-usability of scientific research results. They also serve as building blocks of remote data access and analysis as is required for facilities hosting large data sets and initiatives such as the European Open Science Cloud (EOSC). In this contribution we report from our experience of using Jupyter notebooks for data analysis at research facilities, and outline opportunities and future plans.

Improving User Experience in Complex Systems

ESS, Copenhagen, Denmark

Don Norman and Jakob Nielsen* define User Experience (UX) as "encompassing all aspects of the end-user’s interaction with the company, its services, and its products". The question is, however, is it possible to provide a significantly better UX in an inherently complex environment, such as at a neutron beamline instrument? With this in mind, we decided to ask the professionals at Design Psykology** to see what might be achievable for user-facing scientific software at the ESS. During a series of short workshops, we looked at general UX principles and how they could be applied to two of our user-facing software projects. We learned a number of useful practices and ideas, such as: why UX is more than just the graphical user interface; the value of creating user personas and mapping their workflow; How to design for the user’s "System 1". A bad UX may make the user feel like they are fighting against the system rather than working with it. A good UX, however, will unobtrusively help them do what they need to do without fuss or bother. If done well, UX is not a zero-sum game: improvements can be made so novices and experts alike can work more efficiently.

Improvement of EPICS Software Deployment at NSLS-II

847

A.A. Derbenev
BNL, Upton, New York, USA

The NSLS-II Control System has workstations and servers standardized to the usage of Debian OS. With exceptions like RTEMS and Windows systems where software is built and delivered by hand, all hosts have EPICS software installed from an internally-hosted and externally-mirrored Debian package repository. Configured by Puppet, machines have a similar environment with EPICS base, modules, libraries, and binaries. The repository is populated from epicsdeb, a community organization on GitHub. Currently, packages are available for Debian 8 and 9 with legacy support being provided for Debian 6 and 7. Since packaging creates overhead on how quickly software updates can be available, keeping production systems on track with development is a challenging task. Software is often customized and built manually to get recent features, e.g. for AreaDetector. Another challenge is services like GPFS which underperform or do not work on Debian. Proposed improvements target keeping the production environment up to date. A detachment from the host OS is achieved by using containers, such a Docker, to provide software images. A CI/CD pipeline is created to build and distribute software updates.

ELI-ALPS will be the first large-scale attosecond facility accessible to the international scientific community and its user groups. Control system development has three major directions: vacuum control systems, optical control systems, as well as the integrated control, monitoring and data acquisition systems. The development of the systems has asked for different levels of integration. In certain cases low-level devices are integrated (e.g. vacuum valves), while in other cases complete systems are integrated (e.g. the Tango interface of a laser system). This heterogeneous environment is managed through the elaboration of a common and general architecture. Most of the hardware elements are connected to PLCs (direct control level), which are responsible for the low-level operation of devices, including machine protection functions, and data transfer to the supervisory control level (CLIs, GUIs). Certain hardware elements are connected to the supervisory layer (cameras), as well as the Tango interface of the laser systems. This layer handles also data acquisition with a special focus on the metadata catalogue.

The Laser Megajoule (LMJ) is a 176-beam laser facility, located at the CEA CESTA Laboratory near Bordeaux (France). It is designed to deliver about 1.5 MJ of energy to targets, for high energy density physics experiments, including fusion experiments. Six 8-beams bundles are currently operational. The Front-End is the LMJ subsystem built to deliver the laser pulse which will be amplified into the bundles. It consists of 4 laser seeders, producing the laser pulses with the expected specificities and 88 Pre-Amplifier Modules (PAM). In this paper, we introduce the architecture of the Front-End’s control system which coordinate the operations of the laser seeders and the PAMs’s control systems. We will discuss the ability of the laser seeders and their control systems to inject the 88 PAMs almost independently. Then we will deal with the functions that enable the expected laser performances in terms of energy, spatial and temporal shapes. Finally, the technics used to validate and optimize the operation of the software involved in the Front-End’s equipment performance will be detailed.

Diamond Light Source is a publicly funded 3rd generation national synchrotron which will soon operate 39 state-of-the-art instruments covering a wide range of physical and life science applications. Realization of such instruments poses many challenges from initial scientific concept, to final user experience. To get best efficiency, Diamond operates a modular approach for engineering and software systems support, usually with custom hardware or software component coming together on the final instrument in-situ. To facilitate cross-group collaboration, prototyping, integrated development and testing of the full instrument including scientific case before the final implementation, an optical prototyping setup has been developed which has an identical backend to real beamline instruments. We present detail of the software and hardware components of this environment and how these have been used to develop functionality for the new operational instruments. We present several high impact examples of such integrated prototyping development including the instrumentation for DIAD (integrated Dual Imaging And Diffraction) and the J08 beamline for: soft X-ray ptychography end-station.

The integration of structured data and the PV Access network protocol into the EPICS toolkit has opened up many possibilities for added functionality and features, which more and more facilities are looking to leverage. At the same time however the core developers also have to cope with technical debt incurred in the race to deliver working software. This paper will describe the current status of EPICS 7, and some of the work done in the last two years following the reorganization of the code-base. It will cover some of the development group’s technical and process changes, and echo questions being asked about support for recent language standards that may affect support for older target platforms, and adoption of other internal standards for coding and documentation.

The BNL CA-D controls environment has recently been adopting modern programming languages such as Python. A new framework has been created to instantiate setting and measurement parameters in Python as an alternative to C++ and Java process-variable-like objects. With the help of automated testing tools such as pyTest and Coverage, a test suite is generated and executed before the release of Python-based accelerator device objects (ADO) to assure quality as well as compatibility. This suite allows developers to add custom tests, repeat failed tests, create random inputs, and log failures.

About one hundred channels of pulsed magnet power supply control system were installed in 2017 in KEK electron positron LINAC to realize pulse-to-pulse control of output current every 20 ms. The control system of a group of eight channels totally consists of commercially available devices, namely a PC (Windows 8.1), a PXIe crate and several PXIe boards such as ADC, DAC communication and timing. The software is written with LabVIEW. EPICS channel access protocol is used to communicate with OPI over standard Ethernet network. Depending on the destination of the beam, there are ten beam modes. The software is able to keep parameters for each mode independently, which makes it possible for us to operate one LINAC as if it were ten virtual LINACs. Even Software feedback to compensate small drift of output current is available for each mode independently. During two years of operation, there were no significant problem. Although the Windows is not a real-time OS, dropping rate of the trigger coming every 20 ms is less than a ppm. Rebooting of the PC or software is necessary only a few times in a year.

The National Ignition Facility (NIF) is the world’s largest laser system for Inertial Confinement Fusion (ICF) and High Energy Density (HED) experiments. Design of NIF control system started in the 1990s, incorporating established hardware and software technologies of that era. The architecture of the control system has stood the test of time, successfully scaling up to full 192 laser beam configuration in 2009, and then transitioning to 24x7 operations and sustaining 400 shots annually since 2016. The control system has grown with NIF to add new major capabilities, such as cryogenic layering, a petawatt-class laser, 3D neutron imaging and others. In parallel, with scaling up and efficiency optimizations, the software had to adapt to changes dictated by the fast-paced computer industry. Some of our originally chosen technologies have become obsolete and replaced by new programming languages, frameworks and paradigms. In this talk, we will discuss how the NIF control system has leveraged the strengths of its distributed, cross-platform architecture to successfully modernize "in-place" computing platforms and programming languages without impacting the demanding experiment schedule.

B. Lefort, V. Costa
CERN, Meyrin, Switzerland

The rapid evolution of science and of scientific projects usually implies high levels of mobility among researchers, engineers and applied scientists. In parallel, software development has been getting easier and easier as computing technology has evolved. One direct consequence of these two paradigms is a proliferation of small software that becomes vulnerable in many ways, when the person who develops and maintains it departs. Inspector is a low-code development platform to design control interfaces. It features a visual interface composer, a visual programming language and supports Python. More than 600 Inspector applications are used at CERN. We will explain how people with little experience of writing software can develop applications that they could not otherwise explicitly code for themselves. Finally, we will demonstrate how it offers the organization enhanced security and higher productivity, as well as relieving the load on IT for bug fixes and non-compliance.

LNLS, Campinas, Brazil

A novel solution for integrating EPICS with Compact RIO (cRIO), the real-time embedded industrial controllers by National Instruments (NI), is proposed under the name Nheengatu (NHE). The cRIO controller, which is equipped with a processor running a real-time version of Linux (LinuxRT) and a Xilinx Kintex FPGA, is extremely powerful for control systems since it can be used to program real-time complex data processing and fine control tasks on both the LinuxRT and the FPGA. The proposed solution enables the control and monitoring of all tasks running on LinuxRT and the FPGA through EPICS. The devised solution is not limited to any type of cRIO module. Its architecture can be abstracted into four groups: FPGA and LabVIEW-RT interface blocks, the Nheengatu library, Device Support and IOC. The Nheengatu library, device support and IOC are generic - they are compiled only once and can be deployed on all cRIOs available. Consequently, a setup-specific configuration file is provided to the IOC upon instantiation. The configuration file contains all data for the devised architecture to configure the FPGA and to enable communication between EPICS and the FPGA/LabVIEW-RT interface blocks.

SOLEIL, Gif-sur-Yvette, France

High quality of service is SOLEIL is a key mission since 2007. Historically operation processes and information systems have been defined mostly on the fly by the different teams all along the synchrotron’s journey. Some major outcomes are a limited cross-teams collaboration and a slow learning organization. Consequently, we are currently implementing a holistic approach with common operational processes upon a shared information system. Our first process is "incident management"; an incident is an unplanned disruption or degradation of service. We have tackled incident management for IT* in 2015, then for the accelerators since January 2018. We are starting to extend it to beamlines since beginning 2019. As a follow-up, we will address the "problem management" process (a problem is the cause of one or more incidents) and the creation of a knowledge base for the operation. By implementing those processes, the culture of continuous improvement is slowly spreading, in particular by driving blameless incident and problem analysis. This paper will present the journey we have been through including our results, improvements and difficulties of implementing this new way of thinking.

The Square Kilometre Array (SKA) project is an international collaboration aimed to design and build the world’s largest radio telescope, composed of thousands of antennae and related support systems, with over a square kilometre of collecting area. In order to ensure proper and uninterrupted operation of SKA, the role of the operator at the control room is crucial and the User Interface is the main tool that the operator uses to control and monitor the telescope. During the current bridging phase, a user interface generator has been prototyping. It aims to provide a tool for UI developer to create an own engineeristic user interface compliant with SKA User Interface Design Principle and operator and stakeholder needs. A technology downselection has been made in order to evaluate different web-solution based on TANGO.

This paper presents the development of the Miniscule ELT (MELT) Control Software. MELT is an optical test bench with a turbulence generator, whose main objective is to deploy and validate key functionalities of central control system and the Wavefront control strategies on the Extremely Large Telescope (ELT) during AIV/commissioning and operation phase. The subsystems under control are: a segmented primary mirror, a secondary mirror on a hexapod, an adaptive fourth mirror, a fast tip/tilt mirror, phasing sensor, a light source, a Wavefront sensor, a IR camera, together with their control interfaces that emulate the ELT conditions. The Core Integration Infrastructure will be deployed to MELT for their verification and testing strategy, producing feedback to their requirements and design. This paper describes the Control SW distributed architecture, communication patterns, user interfaces and SW infrastructure. The control algorithms are being developed separately and will be integrated into the control loop via MATLAB scripts.

At the trade-off of power, wireless technologies are much more portable and convenient than their wired counterparts. This is especially true in the scientific sphere, where many environmental factors must be recorded at all times at as many locations as possible. Using these technologies, scientists can often reduce cost while maximizing the number of sensors without compromising sensor quality. To this end, we have developed EPICS controllers for both Bluetooth Low Energy (BLE) sensors and XBee ZigBee sensors. For BLE, we chose the Nordic Thingy:52 for its low cost, high battery life, and impressive range of sensors. The controller we developed combines EPICS base functions, the Bluetooth generic attribute data structure library, and multithreading techniques to enable real-time broadcast of the Thingy’s 20+ sensors’ live values. Because BLE is limited in range, we also developed a controller for the XBee sensor which, through the ZigBee mesh protocol, can expand its range through each node added into the network. With these controllers, NSLS-II scientists will have access to a whole new class of sensors which are both easier to deploy and cheaper than their wired predecessors.

MAX IV Laboratory, Lund University, Lund, Sweden

Projects management of synchrotron is both complicated and complex. Building scientific facilities are resource consuming although largely made out of standard and well known components. The industrial approach of project management resolves this complication by requiring analysis and planning to facilitate the execution of tasks. The complexity comes by all the research making unique the accelerators, the beamlines and its usage. Known unknown requires experiments which evolve continuously causing the development path to be naturally iterative. Agile project management has come a long way since its definition in 2001. Nowadays this method is ubiquitous in the software development industry following different implementation like Scrum or XP and started to evolve at a bigger scale (i.e Scaled Agile) applied within an entire organization. The versatility of the Agile method has been applied to a Scientific technical development program such as the MAX IV Laboratory control system. This article describes the experience of 7 years of Agile project management and the use of Lean Management principles to develop and maintain the control system.

Funding: Argonne National Laboratory’s work was supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under contract DE-AC02-06CH11357
The installation of the APS-U has a short schedule of one year, making it imperative to be well prepared before the installation process begins. The Component Database (CDB) has been designed to help in documenting and tracking all the components for APS-U. Two new major domains, Machine Design domain and Measurement and Analysis Archive (MAARC) domain, have been added to CDB to further its ability in exhaustively documenting components. The Machine Design domain will help define the purpose of all the components in the APS-U design and the MAARC domain allows association of components with collected data. The CDB and a traveler application from FRIB have been integrated to help with documenting various processes performed, such as inspections and maintenance. Working groups have been formed to define appropriate work flow processes for receiving components, using the tools to document receiving inspection and QA requirements. The applications are under constant development to perform as expected by the working groups. Over some time, especially after production procurement began, the CDB has seen more and more usage in order to aid in preparation for the APS-U installation.

Why Should You Invest in Asset Management? A Fire and Gas Use Case

1041

H. Nissen, S. Grau
CERN, Geneva, Switzerland

At present, the CERN Fire and Gas detection systems involve about 22500 sensors and their number is increasing rapidly at the same time as the number of equipped installations grows up. These assets cover a wide spectrum of technologies, manufacturers, models, parameters, and ages, reflecting the 60 years of CERN history. The use of strict rules and data structures in the declaration of the assets can make a big impact on the overall system maintainability and therefore on the global reliability of the installation. Organized assets data facilitates the creation of powerful reports that help asset owners and management address material obsolescence and end-of-life concerns with a global perspective Historically preventive maintenance have been used to assure the correct function of the installations. With modern supervision systems, a lot of data is collected and can be used to move from preventive maintenance towards data driven maintenance (predictive). Moreover it optimizes maintenance cost and increase system availability while maintaining reliability. A prerequisite of this move is a coherence on the assets defined in the asset management system and in the supervision system.

The Cherenkov Telescope Array (CTA) project is the initiative to build the next-generation gamma-ray observatory. With more than 100 telescopes planned to be deployed in two sites, CTA is one of the largest astronomical facilities under construction. The Array Control and Data Acquisition (ACADA) system will be the central element of on-site CTA Observatory operations. The mission of the ACADA system is to manage and optimize the telescope array operations at each of the CTA sites. To that end, ACADA will provide all necessary means for the efficient execution of observations, and for the handling of the several Gb/s generated by each individual CTA telescope. The ACADA system will contain a real-time analysis pipeline, dedicated to the automatic generation of science alert candidates based on the inspection of data being acquired. These science alerts, together with external alerts arriving from other scientific installations, will permit ACADA to modify ongoing observations at sub-minute timescales in order to study high-impact scientific transient phenomena. This contribution describes the challenges, architecture, design principles, and development status of the ACADA system.

The Web Extensible Display Manager (WEDM) was first deployed at Jefferson Lab (JLab) in 2016 with the goal of rendering Extensible Display Manager (EDM) control screens on the web for the benefit of accessibility, and with version 2 our aim is to provide a more general purpose display toolkit by freeing ourselves from the constraints of the EDM dependency. Over the last few years WEDM has been extensively used at JLab for 24/7 information kiosks, on-call monitoring, and by remote users and staff. The software has also been deployed to Oak Ridge National Laboratory, and has become more robust as many bug fixes and contributions have been added. However, adoption and utility of the software as a general purpose control system display manager is limited by EDM, which is no longer actively maintained. A new toolkit can be built on modern frameworks, fully embrace web conventions and standards, and support multiple control system data sources. This new version is a result of a technology review and selection, and introduces a web inspired display file format, a web based display builder, new widgets, and a data interface intended to support pluggable data.

One of the primary diagnostic tools for beam emittance measurement at the Linac Coherent Light Source II (LCLS-II), an upgrade of the SLAC National Accelerator Laboratory’s Linac Coherent Light Source (LCLS) facility, is the wire scanners. LCLS-II’s new Fast Wire Scanner (FWS) is based on a similar mechanical design of linear servo motor with position feedback from an incremental encoder as that for LCLS. With a high repetition rate of up to 1 MHz from the superconducting accelerator of LCLS-II, it is no longer sufficient to use point-to-point EPICS-controlled moves from wire to wire, as continued exposure will damage the wires. The system needs to perform on-the-fly scans, with a single position versus time profile calculated in advance and executed in a single coordinated motion by Aerotech Ensemble motion controller. The new fast wire scanner control system has several advantages over LCLS fast wire scanner controls with the capability to program safety features directly on the drive and integrate machine protection checks on an FPGA. This paper will focus on the software architecture and implementation for LCLS-II Fast Wire Scanners.

The SKA Observatory is approaching the construction of the SKA1 radio telescopes, concluding the pre-construction phase in December 2019. A bridging phase has commenced before construction commences during which lean-agile processes, structures and practices are being prototyped. By the end of the bridging phase we plan to have pivoted from a document based, earned value, stage gated set of processes arranged around pre-construction consortia to a code based, value flow driven, lean-agile set of processes unified around the Scaled Agile Framework. During the bridging process we have onboarded more than 10 agile development teams and in this paper we describe the processes, the main technical and cultural challenges and the preliminary results of adopting a lean-agile culture within the SKA organization.

The Continuous Electron Beam Accelerator Facility (CEBAF) at Jefferson Laboratory is a high power Continuous Wave (CW) electron accelerator. It uses a mixture of of SRF cryomodules: older, lower energy C20/C50 modules and newer, higher energy C100 modules. The cryomodules are arrayed in two anti-parallel linear accelerators. Accurately classifying the type of cavity faults is essential to maintaining and improving accelerator performance. Each C100 cryomodule contains eight 7-cell cavities. When a cavity fault occurs within a cryomodule, all eight cavities generate 17 waveforms each containing 8192 points. This data is exported from the control system and saved for review. Analysis of these waveforms is time intensive and requires a subject matter expert (SME). SMEs examine the data from each event and label it according to one of several known cavity fault types. Multiple machine learning models have been developed on this labeled dataset with sufficient performance to warrant the creation of a limited machine learning software system for use by accelerator operations staff. This paper discusses the transition from model development to implementation of a prototype system.

The project aimed to implement a beamline control and data collection system through a server virtualization system, and was applied to the 5C beamline of the 3rd generation beamline of Pohang Accelerator Laboratory (PAL). The 5C beamline is currently under construction for the FBDD beamline with the goal of building a fully automated beamline. Therefore, the project was started to operate stably and efficiently various systems to be applied to the beamline. The control system was implemented using EPICS software tools and MxDC/MxLive software for data acquisition and storage. The control and data collection system of this beamline is integrated using XCP-ng[1] (XenServer Based), and it is in operation. With the integrated server virtualization system, network organization / simplification and data send/receive between systems are more stabilized. The overall size of the system has been significantly reduced, making maintenance easier.

The 3 years collaboration with ESS* at Lund (Sweden) has given us the opportunity to use new COTS hardware and new tools. Based on that experience, we have developed the IEE (IRFU** EPICS Environment) by retaining relevant and scalable ESS solutions. This platform centralized several functionalities, fully installed by scripting, on a server that is running on a virtual machine. The functionalities are an EPICS environment and the root file system with the kernel for each embedded systems. In order to provide homogeneous EPICS modules between all collaborators, a template was designed and used as containers for new developments. Furthermore, a development and a production workflow is also proposed and strongly recommended. Due to the current responsibility of CEA IRFU to provide an EPICS platform for SARAF** at Tel Aviv (Israel), IEE was chosen as the standard platform for the whole accelerator. This paper will present the new standard IRFU EPICS Environment based on MTCA and virtual machines.

The Electromagnetic Calorimeter (ECAL) is one of the sub-detectors of the Compact Muon Solenoid (CMS), a general-purpose particle detector at the CERN Large Hadron Collider (LHC). The CMS ECAL Detector Control System (DCS) and the CMS ECAL Safety System (ESS) have supported the detector operations and ensured the detector’s integrity since the CMS commissioning phase, more than 10 years ago. Over this long period, several changes to both systems were necessary to keep them in-line with current hardware technologies and the evolution of software platforms. The acquired experience of long-term running of both systems led to the need of major modifications to the original design and implementation methods. Such interventions to either systems, which require mid- to long-term validation, result in a considerable amount of downtime and therefore can only be performed during long LHC shutdown periods. This paper discusses the software and hardware upgrades to be carried out during the LHC Long Shutdown 2 (LS2), with emphasis on the evaluation of design choices concerning custom and standard industrial hardware.

The ATLAS and CMS cryogenic control systems have been operational for more than a decade. Over this period, the number of PLCs faults increased due to equipment ageing, leading to systems failures. Maintenance of the systems started to be problematic due to the unavailability of some PLC hardware components, which had become obsolete. This led to a review of the hardware architecture and its upgrade to the latest technology, ensuring a longer equipment life cycle and facilitating the implementation of modifications to the process logic. The change of the hardware provided an opportunity to upgrade the process control applications using the most recent CERN frameworks and commercial engineering software, improving the in-house software production methods and tools. Integration of all software production tasks and technologies using the Continuous Integration practice allows us to prepare and implement more robust software while reducing the required time and effort. The publication presents the current status of the project, the strategy for hardware migration, enhanced software production methodology as well as the experience already gained from the first implementations.

ELI-ALPS will be the first large-scale attosecond facility accessible to the international scientific community and its user groups. The core business of ELI-ALPS is to generate attosecond pulses and provide these to the prospective users. In order to reach this ultimate goal, one key support area, the engineering development of complex systems as well as the engineering custom design service, has been systematically elaborated based on the standards, recent results, trends and best practices of systems engineering. It covers the boundaries towards all related support areas, from building operation and maintenance, to the custom manufacturing provided by the workshops, with the intention to make the model as well as the daily work as comprehensive and consistent as possible. Different tools have been evaluated and applied through the years, however, a key lessons learned is that some of the most important tools are teamwork, personal communication and constructive conflicts.

DLS, Oxfordshire, United Kingdom

At Diamond we are reviewing the current stack of in-house Software Applications that are used to control our beamline experiments and analyse the data produced by them. We intend to use this process of analysis and investigation to formulate proposals for a revised architecture to address the issues with the existing architecture, making use of the opportunities presented by modern technologies and methods, where appropriate. In doing so we hope to design a more flexible and maintainable system which addresses technical debt and functional limitations that have built up over the lifetime of our current software. This will allow us to go on to implement a powerful acquisition and analysis system to be used with the new facilities of Diamond II.

1248

T. Hoffmann, H. Bräuning
GSI, Darmstadt, Germany

As construction of the FAIR accelerator complex progresses, the existing heavy ion synchroton SIS18, the storage ring ESR and the high energy beam transfer lines HEBT have been upgraded to the future control system. Within this upgrade the beam instrumentation (BI) data acquisition systems (DAQ) have been heavily modernized too. These are now integrated into the control system with its White Rabbit based timing system, data supply (i.e. ion species, energy, etc) and services like archiving. Dedicated clients running in the main control room allow visualization and correlation of the data and status of the BI devices. The DAQ hardware has been upgraded using new state-of-the-art components. With a trend to slowly phase out VME based systems, solutions based on standard Industrial PC for few channels as well as on the new µTCA standard for many channels have been successfully implemented. This contribution will give an overview over the upgraded BI-DAQ systems like current transformers and counter applications for ionization chambers, scintillators, and more. It will also present first experiences during beam operation with the new control system, which started summer last year.

In the world of increasing complexity and integration, experiments often stretch over multiple beamlines or several facilities. Users may come with their own sample environments and detectors. It is always a challenge to integrate user end-station equipment into the hosting facility controls. Recognizing this trend, NSLS2 has developed babyIOC* Control System in Box, portable small-factor IOC solution. The new release comes with CentOS, EPICS, as well as areaDetector-3-5**. The selected hardware is from innovative hardware designer UDOO***, Italy. This SBC has diskless 64-bit Intel architecture, 4-core 2.56 GHz, 8 GB of RAM, x3 1 Gbit interfaces for ~$400 US. System boots and runs from microSD card. Building another system comes to copying the image to another microSD card. We believe this board with the easy downloadable image can be used at any facility and/or experimental stations including Tango systems, that would be interested benefiting from areaDetector package. Given a growing interest to areaDetector software from Tango community, babyIOC could serve as evaluation starting point.

PAL, Pohang, Republic of Korea

At least three different computers are used in the beamline of PAL, first for EPICS IOC, second for device control and data acquisition(DAQ), and third for analyzing data for users. In the meantime, stable beamline control was possible by maintaining the policy of separating applications listed above from the hardware layer. As data volumes grow and the resulting data throughput increases, demands for replacement of highly efficient computers has increased. Advances in virtualization technology and robust computer performance have enabled a policy shift from hardware-level isolation to software-level isolation without replacing all the computers. DAQ and analysis software using the Bluesky Data Collection Framework have been implemented on this virtualized OS. In this presentation, we introduce the DAQ system implemented by this virtualization method.

DESY, Hamburg, Germany

The European-XFEL is an X-ray Free Electron Laser facility located in Hamburg (Germany). The 17.5 GeV superconducting accelerator will provide photons simultaneously to several user stations. Currently 12 Wire Scanner stations are used to image transverse beam profiles in the high energy sections. These scanners provide a slow scan mode for single bunch operation. When operating with long bunch trains (>100 bunches) fast scans are used to measure beam sizes in an almost nondestructive manner. To operate fast scans multiple impacts on the beam loss system (BLM) and the charge transmission interlock (TIS) have to be taken into account. This paper focuses on the interaction between these systems and first experiences performing measurements.

The Square Kilometre Array (SKA) project is responsible for developing the SKA Observatory, the world’s largest radiotelescope ever built. In this context, a number of Graphical User Interfaces (GUI) have to be designed and built to be used for monitoring and control, testing, simulation, integration, commissioning and maintenance. The Tango framework and its UI tools, selected for SKA in 2015, support the types of basic control interfaces currently used at both radio telescopes and within high energy physics experiments. This paper reports on the development of a Qt/Taurus code generator prototype based on the IFML (Interaction Flow Modeling Language) standard and respective modeling tools, that are extended for supporting the platform-specific code generation. The purpose of this work is to enable the use of low-code development in SKA GUI design, thus enabling increased efficiency, reliability and coherency of the produced UI. We present a simple GUI use case as complete example of software development cycle starting from requirements and including IFML modelling, Qt/Taurus automatic coding, interface evaluation and validation.

INFN/LNL, Legnaro (PD), Italy

A nuclear plant, for energy or for nuclear physics, is a complex facility where high level security is mandatory, both for machines and people. But sometimes the status of danger is not correctly felt, inducing workers to misinterpret situations and, as consequence, not act in the best way. At the same time problems related to area accessibility can occur during normal machine operations, limiting actions related to local maintenance and environment supervision. It would be suitable to have the opportunity to perform these tasks in an independently from environment limitations and machine operations. In order to overcome these limits, we applied Virtual Technology to the nuclear physics context. As consequence, this new tool has given us the chance to reinterpret concepts like training or maintenance planning. In this paper the main proof of concept implemented are described and additional information related to different VR technology usages are exposed.

The future upgrades of the LHC (Large Hadron Collider) will increase its luminosity. To fulfill the needs of the detector electronic upgrades and in particular to cope with the extreme radiation environment, the GBT-SCA (Giga-Bit Transceiver - Slow Control Adapter) ASIC was developed for the control and monitoring of on-detector electronics. To benefit maximally from the ASIC, a flexible and hardware interface agnostic software suite was developed. A hardware abstraction layer - the SCA software package - exploits the abilities of the chip, maximizes its potential performance for back-end implementations, provides control over ASIC configuration, and enables concurrent operations wherever possible. An OPC UA server was developed on top of the SCA software library to integrate seamlessly with distributed control systems used for detector control and Trigger/DAQ (Data AcQuisition) configuration, both of which communicate with the GBT-SCA via network-attached optical link receivers based on FPGAs. This paper describes the architecture, design and implementation aspects of the SCA software suite components and their application in the ATLAS experiment.

Managing Cybersecurity for Control System Safety System development environments

R. Mudingay, S. Armanet
ESS, Lund, Sweden

At ESS, we manage cyber security for our control system infrastructure by mixing together technologies that are relevant for each system. User access to the control system networks is controlled by an internal DMZ concept whereby we use standard security tools (vulnerability scanners, central logging, firewall policies, system and network monitoring), and users have to go through dedicated control points (reverse proxy, jump hosts, privileged access management solutions or EPICS channel or PV access gateways). The infrastructure is managed though a DevOps approach: describing each component using a configuration management solution; using version control to track changes, with continuous integration workflows to our development process; and constructing the deployment of the lab/staging area to mimic the production environment. We also believe in the flexibility of visualization. This is particularly true for safety systems where the development of safety-critical code requires a high level of isolation. To this end, we utilize dedicated virtualized infrastructure and isolated development environments to improve control (remote access, software update, safety code management).

The 4th generation light source, PAL-XFEL, is an X-ray free electron laser in Pohang, Korea. One of key features of the event timing system in the PAL-XFEL, the beam synchronous acquisition is used in many beam diagnostics and analysis and the species of that increase gradually. In order to reduce the cost for event receivers which are required for operating the beam synchronous acquisition and to resolve the difficulty of the limited platform dependent on event receivers, we developed the virtual event receiver system receiving timestamps and BSA information from an event generator not using real event receivers. In this paper, we introduce the software architecture of the virtual event receiving system and present test results of it.

The control system, ACNET, for Fermilab’s accelerator complex has enabled the lab’s scientific mission for decades. ACNET has evolved over the years to incorporate new technologies. However, as Fermilab prepares to enter a new era with its PIP-II superconducting linear accelerator, ACNET is at a crossroads. There are several components that are either obsolete or outdated, or certainly will be over the long lifetime of PIP-II. We have begun a plan to modernize our accelerator control system. This paper discusses some of the obsolete hardware and software that needs to be replaced, and lays out options and technologies that we might adopt as part of this modernization effort.

Funding: This work was supported by the U.S. DOE, Office of Nuclear Physics, under Contract DE-AC02-06CH11357. The research used resources of ANL’s ATLAS Facility, a DOE Office of Science User Facility.
The ATLAS (Argonne Tandem Linear Accelerating System) accelerator at Argonne National Laboratory, near Chicago, IL., has recently been upgraded via the addition of a pulsed mode Electron Beam Ion Source (EBIS). Pulsed operation requires finer levels of control of various digital systems like fast switching high-voltage power supplies and remotely controlled function generators. Additionally, pico-level and femto-level ammeters need per-device zero correction and calibration to accurately read beam intensities. As the facility moves away from fast register-based analog signals, new and slower digital protocols adversely affect the perceived execution time of the control system. This work presents options, research, and results of implementing an asynchronous layer between high level user interfaces and the low level communication drivers in order to increase the perceived responsiveness of the system. Solutions are evaluated ranging from in-house codes, which implement system-wide mutual exclusion and prioritization, to drivers available from the EPICS control system. Key performance criteria include ease of implementation, cross platform availability, and overall robustness.

CERN, Geneva, Switzerland

LabVIEW with its graphical approach is suited for engineers used to design and implement systems based on schematics and designs. Being a graphical language, it can be challenging to keep track of drivers, runtime engines, deployments and configurations since most of the tools on the market aimed towards this are implemented for textual languages. Configuration management is possible in the development environment via version control systems such as perforce, however at CERN and in the open source software development community in general, the tendency is moving towards Git. In this paper we demonstrate how the combination of automated builds, packaging, versioning and consistent deployment can further ease and speed up development, while ensure robustness and coherency across systems. We also show how an in-house built tool called "RADE Installer" synchronizes both development environments and drivers across workstations, empowering graphical development at CERN, by merging the open source toolchains with the workflow of LabVIEW. RADE installer represents definitively a solution for LabVIEW to keep track of drivers, runtime engines, deployments and configurations.

Sirius beam diagnostics group is responsible for specifying, designing and developing IOCs for most of the diagnostics in the Booster, Storage Ring and Transport Lines, such as: Screens, Slits, Scrapers, Beam Position Monitors, Tune Measurement, Beam Profile, Current Measurement, Injection Efficiency and Bunch-by-Bunch Feedback. In order to ease maintenance, improve robustness, repeatability and dependency isolation a set of guidelines and recipes were developed for standardizing the IOC deployment. It is based on two main components: containerization, which isolates the IOC in a well-known environment, and a remote boot strategy for our diagnostics servers, which ensures all hosts boot in the same base operating system image. In this paper, the remote boot strategy, along with its constituent parts, as well as the containerization guidelines will be discussed.

DELTA, Dortmund, Germany

During the past decades, a variety of particle optics programs have been applied for accelerator studies at the storage ring facility DELTA. Depending on the application, most programs were used offline without dynamic machine synchronisation. In order to centralize and standardize storage ring modeling capabilities, a dedicated online model server was developed and integrated into the EPICS-based control system. The core server is based on Python/EPICS service modules using OCELOT and COBEA as simulation tools. All data, actual machine readings/settings, conversion coefficients, results of simulation calculations as well as manual parameter settings, are handled via EPICS process variables. Thus, the data are transparently available in the entire control system for further processing or visualisation. To improve maintainability and adaptability, the remote presentation model controller concept was realized in the implementation. The paper explains the setup of the model server and discusses first use cases.

Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-SC0012704 with the U.S. Department of Energy.
Modern instruments are often supplied with rich proprietary software tools, which makes it difficult to integrate them to an existing control systems. The liteServer is very lightweight, low latency, cross-platform network protocol for signal monitoring and control. It provides very basic functionality of popular channel access protocols like CA or pvAccess of EPICS. It supports request-reply patterns: ’info’, ’get’ and ’set’ requests and publish-subscribe pattern: ’monitor’ request. The main scope of the liteServer is: 1) provide control and monitoring for instruments supplied with proprietary software, 2) provide fastest possible Ethernet transactions, 3) make it possible to implement in FPGA without CPU core. The transport protocol is connection-less (UDP) and data serialization format is Universal Binary JSON (UBJSON). The UBJSON provides complete compatibility with the JSON specification, it is very efficient and fast. A liteServer-based system can be connected to existing control system using simple bridge program (bridges for EPICS and RHIC Ado are provided).

At the Spallation Neutron Source, these systems are fully integrated into the EPICS based machine control system to facilitate optimal machine performance. BACnet is the predominant communication protocol used in the building automation industry, thus inspiring SNS to develop a BACnet/IP software driver for EPICS to enable this integration. This paper describes how SNS uses the BACnet driver and standard EPICS tools to perform custom chiller sequencing to manage chiller system performance and meet accelerator requirements for high availability.

NXCALS - Architecture and Challenges of the Next CERN Accelerator Logging Service

extraction, controls, operation, hardware

1465

J.P. Wozniak, C. Roderick
CERN, Geneva, Switzerland

CERN’s Accelerator Logging Service (CALS) is in production since 2003 and stores data from accelerator infrastructure and beam observation devices. Initially expecting 1 TB/year, the Oracle based system has scaled to cope with 2.5 TB/day coming from >2.3 million signals. It serves >1000 users making an average of 5 million extraction requests per day. Nevertheless, with a large data increase during LHC Run 2 the CALS system began to show its limits, particularly for supporting data analytics. In 2016 the NXCALS project was launched with the aim of replacing CALS from Run 3 onwards, with a scalable system using "Big Data" technologies. The NXCALS core is production-ready, based on open-source technologies such as Hadoop, HBase, Spark and Kafka. This paper will describe the NXCALS architecture and design choices, together with challenges faced while adopting these technologies. This includes: write/read performance when dealing with vast amounts of data from heterogenous data sources with strict latency requirements; how to extract, transform and load >1 PB of data from CALS to NXCALS. NXCALS is not CERN-specific and can be relevant to other institutes facing similar challenges.

The high-gain free electron lasers have given scientists hopes for new scientific discoveries in many frontier research areas. The Shanghai HIgh repetition rate XFEL aNd Extreme light facility (SHINE) is under construction in China, which is a quasi-continuous wave hard X-ray free electron laser facility. The control system is responsible for the facility-wide device control, data acquisition, machine protection, high level database or application, as well as network and computing platform. It will be mainly based on EPICS to reach the balance between the high performance and costs of maintenance. The latest technology will be adopted for the high repetition rate data acquisition and feedback system. The details of the control system design will be reported in this paper.

With refrigerating power of the order of 1.5 kW at -35 °C and full compatibility with Detector Control System standards, Light Use Cooling Appliance for Surface Zones (LUCASZ) is the first movable medium size evaporative CO₂ detector cooling system. By 2018 a series of 4 LUCASZ units has been fully deployed by the EP-DT group at CERN. LUCASZ is capable to provide CO₂ cooling for various needs of detector development and testing required for Phase I&II upgrades of LHC experiments. This paper describes selected software and controls hardware ideas used to develop the LUCASZ control system as baseline solutions for CO₂ cooling systems for Phase II upgrade of ATLAS and CMS trackers. The main challenges for future control system development will come from the number of cooling plants, the modularity, operation, and the implementation of backup philosophy. The introduction of automated software generation for both PLC and SCADA is expected to bring major improvement on the efficiency of control system implementation. In this respect, a unification step between experiments is highly required without neglecting specific needs of ATLAS and CMS.

DESY, Hamburg, Germany

The Java Doocs Data Display (jddd) is a Java-based tool for creating and running graphical user interfaces for accelerator control systems. It is the standard graphical user interface for operating the European XFEL accelerator. Since Java 8 Oracle introduced a number of major changes in the Java ecosystem’s legal and technical contexts that significantly impact Java developers and users. The most impactful changes for our software were the removal of Java Web Start, Oracles new licensing model and shorter release cycles. To keep jddd up to date, the source code had to be refactored and new distribution concepts for the different operating systems had to be developed. In this paper the benefits and pitfalls of the jddd migration from Oracle Java8 to OpenJDK¹¹⁺ will be described.

G. Weiss
ESS, Lund, Sweden

At the European Spallation Source, PV Access has been selected as the default EPICS protocol. However, PV Access in the initial releases of EPICS 7 does not implement any access control of client requests. In order to be able to protect selected process variables (PVs) from write requests that may cause harm to the system, some type of access control is needed. This paper details how PV Access is extended to partially reuse the access control available in Channel Access, while at the same time providing additional features. It also explains how ESS intends to deploy and manage access control in terms of infrastructure, tools and responsibilities. Limitations of the access control mechanism are also discussed.

Funding: SKA South Africa National Research Foundation of South Africa Department of Science and Technology
The MeerKAT Control and Monitoring(CAM) solution is a mature software system that has undergone multiple phases of construction and expansion. It is a distributed system with a run-time environment of 15 logical nodes featuring dozens of interdependent, short-lived processes that interact with a number of long-running services. This presents a challenge for the development team to balance operational goals with continued discovery and development of useful enhancements for its users (astronomers, telescope operators). Continuous Delivery is a set of practices designed to always keep software in a releasable state. It employs the discipline of release engineering to optimise the process of taking changes from source control to production. In this paper, we review the current path to production (build, test and release) of CAM, identify shortcomings and introduce approaches to support further incremental development of the system. By implementing patterns such as deployment pipelines and immutable release candidates we hope to simplify the release process and demonstrate increased throughput of changes, quality and stability in the future

In a part of the SPring-8 upgrade project, the SACLA linac will be used as the injector for the SPring-8 storage ring. We will upgrade the beam monitor system for beam transport, which consists of screen monitor (SCM), beam position monitor (BPM) and current monitor (CT). For the SCM, we adopted GigE Vision standard for the CCD camera and EtherCAT as a field bus for the stepper motor control of focusing system. We have developed camera control software using open source libraries to integrate various vendors’ GigE Vision cameras with the SPring-8 control framework. A grabbed image is stored into the file server and property, such as camera settings for image and event number, is stored into the database. The BPM is a key device for precise and stable injection. We adopted the commercially available MTCA.4 fast ADC/DAC module with modified firmware developed for readout of the BPM and the CT. We are developing acquisition software for MTCA.4 modules to synchronize with a beam trigger. The acquired data are stored into the database with time stamp and event number. We present the preparation of beam monitor control system for the beam transport to injection from SACLA to SPring-8.

IRFU* software control team is involved from feasibility studies to equipment deployment into many different experiments by their size and running time. For many years, IRFU is using PLC solution for controlling part of the experiment, and two different SCADA: - MUSCADE, in-house SCADA dedicated to small experiments. - EPICS** for big facilities. With MUSCADE, IRFU has developed a set of tools that gives an easy and a fast way for PLC developers to configure the SCADA. As EPICS projects are growing in our department, we are working now on adapting those tools to EPICS: - PLCParser, which generates an EPICS database for PLC communication (S7PLC, Modbus). - CAFEJava (Channel Access For EPICS Java) API, which runs a simulated EPICS IOC to test EPICS synoptic, and provides EPICS process variables access for any Java application. - Dxf2Opi, which converts Autocad DXF files into OPI files for CSS*** software. - MOONARCH (Memory Optimizer ON ARCHiver Appliance), which reduces EPICS Archiver Appliance**** data files storage.

HZB, Berlin, Germany

A multi modal set-up provides synchrotron radiation with a broad energy range of 80 eV - 10 keV and variable polarization to the EMIL lab at BESSY II. Two canted undulators, five end stations, three monochromators, more than twenty optical elements, sample to source distances of more than 60 m are challenges by its own. The Double Crystal Monochromator (DCM) feeding the U17 hard X-ray beamlines was designed and optimized for stability and resolution. The mechanical concept of the U17/DCM puts high demands on the software. For on-the-fly synchronization of crystal pitch, crystal translation and the cryogenic cooling system rotation, a closed loop feedback is needed to fulfill the control system requirements. Motion programs are used for compensation of the non-linearities of the pitch rotation. Target positions are approached on a well defined path improving reproducibility and positioning time. A non-linear closed loop control provides fine positioning. A setup of the motion controller based on the tpmac module provides the abstraction interface to the complex DCM motion control software. This paper discusses the DCM hardware, the software model and experimental verification.

The Cryogenic Near Infrared Spectropolarimeter (Cryo-NIRSP) will be one of the first light instruments on the Daniel K. Inouye Solar Telescope (DKIST) currently under construction in Hawaii. Cyro-NIRSP is a near- and thermal- IR imager and spectrograph operating in a cryogenic environment. It will be used to study the faint solar coronal magnetic field across a large field-of-view. Such a complex and precise instrument demands equal requirements from the control system. The control system must handle the many sub-components (e.g. cameras, polarimeter, mirrors) and bring them all together to manage the setup, timings, synchronization, real time motion and overall monitoring. It is built within the pre-defined DKIST software framework, which provides consistency across all instruments. This paper will discuss how such a control system has been achieved for the Cryo-NIRSP instrument detailing some of the challenges that were overcome relating to the synchronization of specific components and the complex inter-dependencies between configurables. It will also touch on the data processing and visualization software development for the end-to-end functioning of the instrument.

Synchrotron end-stations consist of a complex network of devices. The setup is not static and is often upgraded. The data acquisition systems are constantly challenged by such changes and upgrades, so scalability and flexibility are crucial skills. DonkiOrchestra is a ZeroMQ-based framework for data acquisition and experiment control based on an advanced software trigger-driven paradigm. In the DonkiOrchestra approach a software device, referred to as Director, provides the logical organization of the experiment as a sequential workflow relying on triggers. Each software trigger activates a set of Actor devices that can be hierarchically organized according to different priority levels. Data acquired by the Actors is tagged with the trigger number and stored in HDF5 archives. The intrinsic asynchronicity of ZeroMQ maximizes the opportunity of performing parallel operations and sensor readouts. This paper describes the software architecture behind DonkiOrchestra, which is fully configurable and scalable, so it can be reused on multiple endstations and facilities. Furthermore, experimental applications at Elettra beamlines and future developments are presented and discussed.

CERN, Geneva, Switzerland

The operation of the LHC at CERN is highly dependent on its associated infrastructure to operate properly, such as its cryogenic system where many conditions must be fulfilled for superconducting magnets and RF cavities. In 2018, the LHC cryogenic system caused 172 hours of accelerator downtime (out of 5760 running hours). Since the cryogenics recovery acts as a time amplifier, it is important to identify not optimized processes and malfunctioning systems at an early stage to anticipate losses of availability. The LHC cryogenic control systems embeds about 60,000 I/O whereof more than 20,000 analog signals which have to be monitored by operators. It is therefore crucial to select only the relevant and necessary information to be presented. This paper presents a signal analysis system created to automatically generate adequate daily reports on potential problems in the LHC cryogenic system which are not covered by conventional alarms, and examples of real issues that have been found and treated during the 2018 physics run. The analysis system, which is written in Python, is generic and can be applied to many different systems.

NuPIC (Numenta Platform for Intelligent Computing) is an open-source computing platform that attempts to mimic neurological pathways in the human brain. We have used the Python implementation to explore the utility of using this system to detect anomalies in both stored and real-time data coming from the controls system for the RHIC Collider at Brookhaven National Laboratory. This paper explores various aspects of that work including the types of data most suited to anomaly detection, the likelihood of developing false positive and negative anomaly results, and experiences with training the system. We also report on the use of this software for monitoring various parts of the controls system in real-time.

The phase 1 of the SPIRAL2 facility, the extension project of the GANIL laboratory in Caen, France, is to be commissioned. The accelerator, composed of a normal conducting RFQ and a superconducting linac, is designed to accelerate high power deuteron and heavy ion beams up to 200 kW. A Machine Protection System (MPS) has been implemented to protect the accelerator from thermal damages for this very large range of beam intensities. This paper presents the solutions chosen for this system, composed of three subsystems: one dedicated to thermal protection which requires a PLC and a fast electronic system, a second one dedicated to enlarged safety protection, and a third safety subsystem dedicated to fast vacuum valve protection. Both of those subsystems work associated with a global EPICS-based control and HMI system, which gives the operation team global supervision of the accelerator and allows controlling sensor trigger thresholds, interlock system, beam initialization and power increase through the beam time structure. The MPS has been developed and is currently tested to be ready for the incoming SPIRAL2 commissioning.

In September 2017 the European XFEL entered user operation after years of construction and one year of commissioning. To provide a fast and flexible startup of the various sections of the machine, the high-level control software was essential from the beginning. While progressing in commissioning and increasing operation parameter space, the enormous complexity of the European XFEL put hard requirements on the control and operation concepts. Having now the full baseline parameters reached, this paper will review the high-level software concepts and architecture in respect to effectiveness, reliability and ease of operation. Beside a review of the high-level software concepts and design ideas also general operation concepts and the interoperability between the various sub-systems in respect to the overall facility performance will be presented.
