MOAPP03	Control System Plans for SNS Upgrade Projects	controls, target, EPICS, neutron	12
	S.M. Hartman, K.S. White ORNL, Oak Ridge, Tennessee, USA
	Funding: This material is based upon work supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under contract number DE-AC05-00OR22725. The Spallation Neutron Source at Oak Ridge National Laboratory is planning two major upgrades to the facility. The Proton Power Upgrade project, currently underway, will double the machine power from 1.4 to 2.8 MW by adding seven additional cryomodules and associated equipment. The Second Target Station project, currently in conceptual design, will construct a new target station effectively doubling the potential scientific output of the facility. This paper discusses the control system upgrades required to integrate these projects into the existing EPICS based control systems used for the machine and neutron instrument beamlines. While much of the control system can be replicated from existing solutions, some systems require new hardware and software. Operating two target stations simultaneously will require a new run permit system to safely manage beam delivery.

	Funding: This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344 The National Ignition Facility (NIF) is the world’s most energetic laser experimental facility with 192 beams capable of delivering 2.1 MJ of 500 TW ultraviolet laser light to a target. NIF experiments facilitate the study of extreme physical conditions at temperatures exceeding 100 million K and 100 billion times atmospheric pressure allowing scientists the ability to generate conditions similar to the center of the sun and explore the physics of planetary interiors, supernovae and thermonuclear burn. This year concludes a series of optimizations and enhancements to the control & information systems to sustain the quantity of experimental target shots while developing an enhanced precision diagnostic system to optimize and increase the power and energy capabilities of the facility. In addition, many new system control and diagnostic capabilities have been commissioned to increase the understanding of target performance. This year also concludes a multi-year sustainability project to migrate the control system software to Java. This talk will report on the current status of each of these areas in support of the wide variety of experiments being conducted.

MOBPP02	Designing a Control System for Large Experimental Devices Using Web Technology	controls, EPICS, status, framework	28
	W. Zheng, N. Fu, S. Li, Y. Wang, F.Y. Wu, M. Zhang Huazhong University of Science and Technology, State Key Laboratory of Advanced Electromagnetic Engineering and Technology,, Hubei, People’s Republic of China
	EPICS is mature in accelerator community. However, there are endeavors to improve existing control system software like Tango and EPICS 7 mainly driven by the needs of flexibility of the control system and the development of computer technology. This paper presents a new way of building a large experimental device control system using web technology instead of EPICS toolkit. The goal is to improve the interoperability of the control system allowing different component in the control system to talk to each other effortlessly. An abstraction of the control system is made. The control system components are abstracted into resources. The accessing of the resources is done via standard HTTP RESTful web API. HMI is based on HTML and JavaScript in browsers. Web Socket is used for event distribution. The main feature of this design is that all interfaces in the system are based on open web standards, which are interoperable among almost all kinds of devices. The paper also presents a software toolkit to build this kind of control system. A control system for a diagnostic on J-TEXT tokamak built using this toolkit will be presented.

MOBPP05	Dynamic Control Systems: Advantages and Challenges	controls, TANGO, interface, database	46
	S. Rubio-Manrique, G. Cuní ALBA-CELLS Synchrotron, Cerdanyola del Vallès, Spain
	The evolution of Software Control Systems introduced the usage of dynamically typed languages, like Python or Ruby, that helped Accelerator scientists to develop their own control algorithms on top of the standard control system. This new high-level layer of scientist-developed code is prone to continuous change and no longer restricted to fixed types and data structures as low-level control systems used to be. This provides great advantages for scientists but also big challenges for the control engineers, that must integrate this dynamic developments into existing systems like user interfaces, archiving or alarms.

MOCPL01	IBEX: Beamline Control at ISIS Pulsed Neutron and Muon Source	controls, neutron, EPICS, software	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, software, 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.

MOCPL06	2D-Nano-Ptychography Imaging Results on the SWING Beamline at Synchrotron SOLEIL	controls, feedback, synchrotron, electron	91
	C. Engblom, Y.-M. Abiven, F. Alves, F. Berenguer, T. Bizien, A. Gibert, F. Langlois, A. Lestrade, P. Montaville, J. Pérez SOLEIL, Gif-sur-Yvette, France
	A new Nanoprobe system, which was originally developed in the scope of a collaboration with MAXIV (Sweden), has recently been tested and validated on the SWING beamline in Synchrotron SOLEIL. The aim of the project was to construct a Ptychography nano-imaging station. Initial steps were taken to provide a portable system capable of nanometric scans of samples with sizes ranging from the micrometer to fractions of a millimeter. Imaging was made possible by actuating a total of 16 Degrees Of Freedom (DOF) composed of a sample stage (3 DOF), a central stop stage (5 DOF), a Fresnel zone plate stage (5 DOF), as well as an order sorting aperture stage (3 DOF). These stages were actuated by an ensemble of piezo-driven and high-quality brushless motors, of which synchronized control (with kinematic modelling) was done using the Delta Tau platform. In addition, interferometry feedback was used for reconstruction purposes. Imaging results are promising: the system was able to resolve 40 nm measured with a Siemens star, the paper will describe the system and the achieved results.

MOCPR01	Graduate Software Engineer Development Program at Diamond Light Source	controls, software, 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.

MOMPL007	The Design of Intelligent Integrated Control Software Framework of Facilities for Scientific Experiments	controls, software, framework, monitoring	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.

MOMPR002	Improving User Information by Interfacing the Slow Control’s Log and Alarm Systems to a Flexible Chat Platform	controls, interface, GUI, operation	152
	M. Ritzert Heidelberg University, Heidelberg, Germany
	Research groups operating large experiments are often spread out around the globe, so that it can be a challenge to stay informed about current operations. We have therefore developed a solution to integrate a slow control system’s alarm and logging systems with the chat system used for communication between experimenters. This integration is not intended to replace a control screen containing the same information, but offers additional possibilities: - Instead of having to open the control system’s displays, which might involve setup work (VPN, remote desktop connections, …), a web interface or an app can be used to track important events in the system. - Messages can easily be filtered and routed to different recipients (individual persons or chat rooms). - Messages can be annotated and commented on. The system presented uses Apache Camel to forward messages received via JMS to Rocket. Chat. Since no binding to Rocket. Chat was available, this interface has been implemented. On the sending side, a C++ logging library that integrates with EPICS IOCs and interfaces with JMS has been designed. For the Belle II PXD collaboration.

	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, software	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, scattering, operation, software	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.

MOPHA001	Robotizing SOLEIL Beamlines to Improve Experiments Automation	controls, detector, synchrotron, interface	183

	Beamlines can benefit from the implementation of industrial robots in several ways: minimization of dead time, maximization of experimental throughput, and limitation of human presence during experimentation. Furthermore, the robots add flexibility in task management. The challenge for SOLEIL is to define a robotic standard, on both hardware and software, which is versatile enough to cover beamlines requirements, while being easy to implement, easy to use, and to maintain in operation. This paper will present the process of defining such a standard at SOLEIL, using 6 axis industrial robot arms. It will detail all aspects of this development, from market studies up to technical constraints. The specifications of the robots are aimed at addressing the most common technical constraints of beamlines, with a special care for mechanical properties. The robotic systems will be integrated into the Tango control system using a feature-based approach. This standard implementation is driven by two applications: picking and placing samples for powder diffraction on the CRISTAL beamline and positioning of a detector for x-rays coherent diffraction experiments on the NANOSCOPIUM beamline.

	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.

MOPHA063	Towards a Common Reliability & Availability Information System for Particle Accelerator Facilities	operation, database, medical-accelerators, radiation	356
	K. Höppner, Th. Haberer, K. Pasic, A. Peters HIT, Heidelberg, Germany J. Gutleber, A. Niemi CERN, Meyrin, Switzerland H. Humer AIT, Vienna, Austria
	Funding: This project has received funding from the European Union’s Horizon 2020 Research and Innovation program under grant agreement No 730871. Failure event and maintenance record based data collection systems have a long tradition in industry. Today, the particle accelerator community does not possess a common platform that permits storing and sharing reliability and availability information in an efficient way. In large accelerator facilities used for fundamental physics research, each machine is unique, the scientific culture, work organization, and management structures are often incompatible with a streamlined industrial approach. Other accelerator facilities enter the area of industrial process improvement, like medical accelerators due to legal requirements and constraints. The Heidelberg Ion Beam Therapy Center is building up a system for reliability and availability analysis, exploring the technical and organizational requirements for a community-wide information system on accelerator system and component reliability and availability. This initiative is part of the EU H₂020 project ARIES, started in May 2017. We will present the technical scope of the system that is supposed to access and obtain information specific to reliability statistics in ways not compromising the information suppliers and system producers.

MOPHA073	Recent Updates of the RIKEN RI Beam Factory Control System	controls, EPICS, power-supply, cyclotron	384
	M. Komiyama, M. Fujimaki, N. Fukunishi, A. Uchiyama RIKEN Nishina Center, Wako, Japan
	We report on two latest updates of the RIKEN Radioactive Isotope Beam Factory (RIBF) control system. First, the successor of the existing beam interlock system (BIS) operated since 2006 was developed in 2019. As a first step, it covers a small part of the RIBF facility. The new interlock system is based on a programmable logic controller (PLC) and uses a Linux-based PLC-CPU on that the Experimental Physics and Industrial Control System (EPICS) programs can be executed in addition to a sequencer. By using two kinds of CPUs properly according to the speed required for each signal handled in the system, we succeeded in reducing the response time less than one third of the BIS in the performance test using prototype. Second, we plan to expand coverage of the alarm system. We have applied the Best Ever Alarm System Toolkit (BEAST) for several years in addition to the Alarm Handler mainly to vacuum components. We have tried to include the magnet power supplies but found difficulties in treating old power supplies having large fluctuations of read-out values of their excitation currents in an appropriate manner. Our trials to overcome this problem will be presented.

	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.

	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.

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.

MOPHA141	Dynamic System Reliability Modelling of SLAC’s Radiation Safety Systems	controls, PLC, operation, electron	558
	F. Tao, K.W. Belt SLAC, Menlo Park, California, USA
	When the LCLS-II project is complete, there will be three major Department of Energy (DOE) beam programs occupying the same 2-mile long accelerator tunnel, e.g. LCLS, LCLS-II and FACET-II. In addition to the geographical overlap, the number of beam loss monitors of all types has been also significantly expanded to detect power beam loss from all sources. All these factors contribute to highly complex Radiation Safety Systems (RSS) at SLAC. As RSS are subject to rigorous configuration control, and their outputs are permits directly related to beam production, even small faults can cause a long down time. As all beam programs at SLAC have the 95% beam availability target, the complex RSS’s contribution to overall beam availability and maintainability is an important subject worth detailed analysis. In this paper, we apply the dynamic system reliability engineering techniques to create the RSS reliability model for all three beam programs. Both qualitative and semi-quantitative approaches are used to identify the most critical common causes, the most vulnerable subsystem as well as the areas that require future design improvement for better maintainability.

	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.

MOPHA163	The Detector Control System of the Muon Forward Tracker for the ALICE Experiment at LHC	detector, controls, power-supply, framework	617
	K. Yamakawa Hiroshima University, Faculty of Science, Higashi-Hirosima, Japan
	ALICE is the LHC experiment specifically devoted to the study of heavy-ion collisions. The Muon Forward Tracker (MFT) is one of the new detectors developed in the framework of the upgrade programs towards the LHC Run 3 starting from 2021. A Detector Control System (DCS) was developed for the MFT within the new framework of the upgraded ALICE central DCS. In this framework, detectors will deliver physics raw data as well as slow control data. The central DCS will be composed of an interface, named Alice Low level FRont-End Device (ALFRED), to convert high-level words within the DCS to low-level words which are sent to the detector FEE as commands. Used Supervisory Control And Data Acquisition (SCADA) is WinCC Open Architecture (OA). In addition, Joint Control Project Framework is installed to provide standard DCS solutions such as a Finite State Machine (FSM) commonly used by the LHC experiments. The FSM, as a base of the DCS hierarchy, was fully developed and successfully tested. A test bench of the MFT DCS was built as a minimal setup of the full DCS chain consisting of WinCC OA, ALFRED, a demonstration board of a DCS chip and a readout board. The latest status will be presented.

	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.

TUBPL01	Automatic Web Application Generation From an Irradiation Experiment Data Management Ontology (IEDM)	radiation, interface, operation, data-management	687
	B. Gkotse, F. Ravotti CERN, Meyrin, Switzerland B. Gkotse, P. Jouvelot MINES ParisTech, PSL Research University, Paris, France
	Funding: This project has received funding from the European Union’s Horizon 2020 Research and Innovation program under Grant Agreement no. 654168 Detectors and electronic components in High-Energy Physics experiments are nowadays often exposed to harsh radiation environments. Thus, to insure reliable operation over time, their radiation tolerance must be assessed beforehand through dedicated testing experiments in irradiation facilities. To prevent data loss and perform accurate experiments, these facilities need to rely upon a proper data management system. In prior work, we provided a formal description of the key concepts involved in the data management of irradiation experiments using an ontology (IEDM). In this work, we show how this formalisation effort has a practical by-product via the introduction of an ontology-based methodology for the automatic generation of web applications, using IEDM as a use case. Moreover, we also compare this IEDM-generated web application to the IRRAD Data Manager (IDM), the manually developed web application used for the data handling of the CERN Proton Irradiation facility (IRRAD). Our approach should allow irradiation facility teams to gain access to state-of-the-art data management tools without incurring significant software development effort.

TUBPL03	Experimental Data Transfer System BENTEN at SPring-8	synchrotron, synchrotron-radiation, radiation, operation	702
	T. Matsumoto, Y. Furukawa, Y. Hiraoka, M. Kodera, T. Matsushita, K. Nakada, A. Yamashita, S. Yokota JASRI, Hyogo, Japan
	Recently, there are strong demands on open data to promote data science like material informatics. At SPring-8, we have been operated data transfer system for open data of XAFS measurements since 2013* with the second in the world for amount data*. However, it was difficult to satisfy demands such as generic uses in experimental stations and data federation with other facilities. To overcome these, we newly developed data transfer system BENTEN. BENTEN provides easy-to-use and unified interface with REST API for data access from both inside and outside SPring-8. At SPring-8, proposal number is assigned for each experiment and members in the proposal are defined in DB. BENTEN can also realize restricted data access with the members using authentication and the DB. Data registration was performed with metadata such as experimental conditions and samples. Various metadata in the experiments can be easily defined. To achieve flexible data access with full-text search, we used Elasticsearch as metadata store. We began operation of BENTEN and open access of XAFS data since March this year. We plan to utilize BENTEN to promote open data and data science also with other experimental data. H.

TUBPL04	Public Cloud-based Remote Access Infrastructure for Neutron Scattering Experiments at MLF, J-PARC	operation, neutron, software, monitoring	707
	K. Moriyama CROSS, Ibaraki, Japan T. Nakatani JAEA/J-PARC, Tokai-mura, Japan
	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. Various architectures provided by public clouds enable advanced systems to develop quickly and effectively. Our cloud-based infrastructure comprises services for experimental monitoring, data download and data analysis, using architectures, such as object storage, event-driven server-less computing, and virtual desktop infrastructure (VDI). Facility users can access this infrastructure using a web browser and a VDI client. This contribution reports the current status of the remote access infrastructure.

TUBPR02	A 4-Channel, 7 ns-Delay Tuning Range, 400 fs-Step, 1.8 ps RMS Jitter, Delay Generator Implemented in a 180 nm CMOS Technology	timing, controls, power-supply, target	733

	This paper discloses the integration, in a 180 nm CMOS technology, of a 4-channel delay generator dedicated to synchronization down to a few ps. The delay generation principle relies on the linear charge of a capacitor triggered by the input pulse. The output pulse generation occurs when the capacitor voltage exceeds a threshold voltage. The delay full scale is automatically set to match the period of the master clock, ranging from 5-7 ns, with the help of an embedded calibration circuit. The delay value is controlled with the help of a 14-bit DAC setting the threshold voltage, which leads to a 400 fs delay step. Among other features, the chip embeds a combination mode of either 2 or 4 channels to output narrow width pulses. The chip is fully compliant with LVDS, LVPECL and CML differential input pulses and outputs LVPECL pulses. The chip has been fully characterized over temperature (0 to 60 °C) and supply voltage (± 10%). The chip is compliant with pulse repetition frequencies up to 20 MHz. The measured INL is 100 LSB and the RMS jitter is 1.8 ps. The power consumption has been measured to 350 mW for 4 active channels.

TUBPR06	Laser Megajoule Timing System	timing, laser, diagnostics, target	749
	T. Somerlinck, T. Falgon CEA, LE BARP cedex, France N. Bazoge, S. Hocquet, D. Monnier-Bourdin Greenfield Technology, Massy, France
	The aim of the Laser Megajoule facility (LMJ) is to deliver more than 1 MJ of laser energy to targets for high energy density physics experiments. In association with Greenfield Technology, we developed a specific timing system to synchronize the 176 laser beams on the target with a precision better than 40 ps rms and to trigger and mark plasma diagnostics. The final architecture, settled and used since three years, is based on a master oscillator that sends a clock with serial data through a fiber-optic network, allowing to synchronize more than 500 delay generators spread over the large LMJ facility. The settings of each laser beam and the various experiments require different sampling rates (multi to single shot) and 16 groups for coactivity. Three kinds of delay generators, electrical and optical, are designed for standard precision (<150 ps jitter) and the third is designed for high precision. Each output deliver trigger or fiducial signals with jitter down to 5 ps and peak-to-peak wander less than 10 ps over a week. Test performance of this LMJ timing system is in progress all over the LMJ facility. Besides it will be installed on the petawatt laser (PETAL) this year.

TUCPR01	Developing a Toolkit for Analysis of LCLS Pump-Probe Data	detector, framework, photon, interface	795
	S. Nelson SLAC, Menlo Park, California, USA
	Funding: This work was performed in support of the LCLS project at SLAC supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under Contract No. DE-AC02-76SF00515 The data format and volume at LCLS requires significant computing expertise which not all user groups can provide. We will describe the path to and current status of a Python module that enables user groups to translate and reduce their data into a format that they can easily work with. The package is developed in Python and uses the standard LCLS data analysis framework. It encapsulates knowledge of the standard beam line components and adds convenient ways to reduce the data of larger detectors. Both an event-based (best for small event sizes) and a binned approach which is able to handle larger data as megapixel size detectors are simple to setup. MPI is used for fast turn around, enabling close to real time feedback necessary to make decisions of how to use the limited amount of beam time. Jupyter notebooks are provided to demonstrate some of the available options and can serve as a convenient quick start for fast turn around analysis.

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.

TUCPR04	Improving User Experience in Complex Systems	interface, software, neutron, status	812
	M.J. Clarke, G.C. Murphy, R. Nørager, T.S. Richter 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. https://www.nngroup.com/articles/definition-user-experience/ *https://www.designpsykologi.dk/

TUCPR05	UX Focused Development Work During Recent ORNL EPICS-Based Instrument Control System Upgrade Projects	controls, scattering, neutron, detector	818
	X. Yao, R.D. Gregory, G.S. Guyotte, S.M. Hartman, K.-U. Kasemir, C.A. Lionberger, M.R. Pearson ORNL, Oak Ridge, Tennessee, USA
	Funding: Oak Ridge National Laboratory is managed by UT-Battelle LLC for the US Department of Energy The importance of usability and easy-to-use user interfaces (UI) have been recognized across many domains. However, the user-friendliness of scientific experiment control systems often lags behind industry standards in the flourishing user experience (UX) field. Scientific control systems can certainly benefit from these new UX research methods and approaches. Recent instrument control system upgrade projects at the SNS and HFIR facilities at Oak Ridge National Laboratory demonstrate the effectiveness of UX focused development work, and further reveal the need for more utilization of such techniques coming from the UX field. The ongoing control system upgrades are targeting the key facility-level priority of higher scientific productivity, and UX is one of the important tools to help us achieve this priority. We will highlight research methods and practices, introduce our findings and deliverables, and share challenges and lessons learned in applying UX methods to scientific control systems.

WECPL02	Roadmap to 100 Hz DAQ at SwissFEL: Experiences and Lessons Learned	FEL, operation, timing, controls	909
	T. Celcer, A. Babic, S.G. Ebner, F. Märki, L. Sala PSI, Villigen PSI, Switzerland
	Providing reliable and performant Data Acquisition System (DAQ) at Free Electron Lasers (FELs) is a challenging and complex task due to the inherent characteristics of a pulsed machine and consequent need of beam synchronous shot-to-shot DAQ, which enables correlation of collected data associated with each FEL pulse. We will focus on experiences gathered during the process of moving towards 100 Hz operation at SwissFEL from the perspective of beam synchronous DAQ. Given the scarce resources and challenging deadlines, a lot of efforts went into managing conflicting stakeholder expectations and priorities and into allocation of time for operation support and maintenance tasks on one side and time for design and development tasks on the other side. The technical challenges we encountered have shown a great importance of having proper requirements in the early phase, a well thought system design concept, which considers all subsystems in the DAQ chain, and a well-defined test framework for validation of recorded beam synchronous data.

WEDPL02	AliECS: A New Experiment Control System for the Alice Experiment	controls, detector, operation, distributed	956
	T. Mrnjavac, K. Alexopoulos, V. Chibante Barroso, G.C. Raduta CERN, Geneva, Switzerland
	The ALICE Experiment at CERN LHC (Large Hadron Collider) is undertaking during Long Shutdown 2 in 2019-2020 a major upgrade, which includes a new computing system called O² (Online-Offline). To ensure the efficient operation of the upgraded experiment along with its newly designed computing system, a reliable, high performance and automated experiment control system is being developed with the goal of managing all O² synchronous processing software, and of handling the data taking activity by interacting with the detectors, the trigger system and the LHC. The ALICE Experiment Control System (AliECS) is a distributed system based on state of the art cluster management and microservices which have recently emerged in the distributed computing ecosystem. Such technologies will allow the ALICE collaboration to benefit from a vibrant and innovating open source community. This communication illustrates the AliECS architecture. It provides an in-depth overview of the system’s components, features and design elements, as well as its performance. It also reports on the experience with AliECS as part of ALICE Run 3 detector commissioning setups.

WEDPL04	Consolidation and Redesign of CERN Industrial Controls Frameworks	controls, framework, interface, operation	963
	P. Golonka, F. Varela CERN, Meyrin, Switzerland
	The Industrial Controls Frameworks, JCOP and UNICOS, have been employed to develop hundreds of critical controls applications in multiple domains like the detector control system, accelerator complex (cryogenics, powering, interlocks) or technical infrastructure, leading to an unprecedented level of homogeneity. These frameworks, used by a thousand of developers worldwide, will now undergo a major consolidation and re-engineering effort to prepare them for the new challenges of the next 20 years in the HL-LHC era, and streamline their maintenance. The paper presents the challenges that will be faced during this project due to the breadth of technological stack and large code-base contributed over two decades by numerous authors. Delivery of innovation induced by evolution of technologies and refactoring of the ageing code must be done in a way that ensures backward-compatibility for existing systems. The vision and the current state of the frameworks is discussed, alongside the main deliveries planned in the medium term. Lessons learnt, optimizations of processes to make best use of available resources and efforts towards open-source licensing of the frameworks are also presented.

WEMPR001	Data Analysis Infrastructure for Diamond Light Source Macromolecular & Chemical Crystallography and Beyond	detector, database, monitoring, data-acquisition	1031
	M. Gerstel, A. Ashton, R.J. Gildea, K. Levik, G. Winter DLS, Oxfordshire, United Kingdom
	The Diamond Light Source data analysis infrastructure, Zocalo, is built on a messaging framework. Analysis tasks are processed by a scalable pool of workers running on cluster nodes. Results can be written to a common file system, sent to another worker for further downstream processing and/or streamed to a LIMS. Zocalo allows increased parallelization of computationally expensive tasks and makes the use of computational resources more efficient. The infrastructure is low-latency, fault-tolerant, and allows for highly dynamic data processing. Moving away from static workflows expressed in shell scripts we can easily re-trigger processing tasks in the event that an issue is found. It allows users to re-run tasks with additional input and ensures that automatically and manually triggered processing results are treated equally. Zocalo was originally conceived to cope with the additional demand on infrastructure by the introduction of Eiger detectors with up to 18 Mpixels and running at up to 560 Hz framerate on single crystal diffraction beamlines. We are now adapting Zocalo to manage processing tasks for ptychography, tomography, cryo-EM, and serial crystallography workloads.

	Funding: This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344 The past decade has seen great advances in web technology, making the browser the de-facto platform for many user applications. Advances in JavaScript, and innovations such as TypeScript, have enabled developers to build large scale applications for the web without sacrificing code maintainability. However, this rapid growth has also been accompanied by turbulence. AngularJS arrived and saw widespread adoption only to be supplanted by Angular 2+ a few years later; meanwhile other JavaScript-based languages and developer tools have proliferated. At the National Ignition Facility (NIF), the Shot Setup Tool (SST) is a large web-based tool for configuring experiments on the NIF that is being developed to replace legacy Java Swing application. We will present our experience in building SST during this turbulent time, including how we have leveraged TypeScript to greatly enhance code readability and maintainability in a multi-developer team, and our current effort to incrementally migrate from AngularJS to React.

WEMPR008	Web Extensible Display Manager 2	controls, framework, interface, software	1057
	R.J. Slominski, T.L. Larrieu JLab, Newport News, Virginia, USA
	Funding: Authored by Jefferson Science Associates, LLC under U.S. DOE Contract No. DE-AC05-06OR23177 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.

WEMPR010	Anomaly Detection for CERN Beam Transfer Installations Using Machine Learning	detector, feedback, controls, kicker	1066
	T. Dewitte, W. Meert, E. Van Wolputte Katholieke Universiteit Leuven, Leuven, Belgium P. Van Trappen CERN, Geneva, Switzerland
	Reliability, availability and maintainability determine whether or not a large-scale accelerator system can be operated in a sustainable, cost-effective manner. Beam transfer equipment (e.g. kicker magnets) has potentially significant impact on the global performance of a machine complex. Identifying root causes of malfunctions is currently tedious, and will become infeasible in future systems due to increasing complexity. Machine Learning could automate this process. For this purpose a collaboration between CERN and KU Leuven was established. We present an anomaly detection pipeline which includes preprocessing, detection, postprocessing and evaluation. Merging data of different, asynchronous sources is one of the main challenges. Currently, Gaussian Mixture Models and Isolation Forests are used as unsupervised detectors. To validate, we compare to manual e-logbook entries, which constitute a noisy ground truth. A grid search allows for hyper-parameter optimization across the entire pipeline. Lastly, we incorporate expert knowledge by means of semi-supervised clustering with COBRAS.

	Nowadays there is a growing need for user friendly workflow editors in all fields of scientific research. A special interest group is present at big physics research facilities where instrumentation is mostly controlled by a robust, and reliable low level control software solution. Different types of specific experiments using predetermined automated protocols and on-line data processing with real-time feedback require a more flexible and abstract high level control system. Beside flexibility and dynamism, easy usability is also required for researchers collaborating from several different fields. Tentatively, to test the ease and flexible usability, the Kepler workflow-engine was integrated with Tango. It enables researchers to automate and document experiment protocols without any programming skill. The X-ray crystallography laboratory at the Biological Research Center of Hungarian Academy of Science (BRC) has implemented an example crystallographic workflow to test the integrated system. This development was performed in cooperation with ELI-ALPS. S. Brockhauser, et al., Acta Cryst., D68, pp. 975-984, 2012. **P.

	The experimental capabilities at the MAX IV synchrotron consists of 17 beamlines at full capacity. Each beamline puts different requirements on the control system in terms of data acquisition, high performance, data volume, pre-processing needs, and fast experiment feedback and online visualization. Therefore, high demands are put on the data management systems, and the reliability and performance of these systems has a big impact on the overall success of the facility. At MAX IV we have started the DataStaMP (Data Storage and Management Project) with the aim of providing a unified and reliable solution for all data sources in our facility. This work presents the control system aspects of the project. It is initially aimed at providing data management solution for a selected number of detectors and beamlines. It is developed in a modular and scalable architecture and combines several programming languages and frameworks. All the software runs in a dedicated cluster and communicates with the experimental stations through high performance networks, using gRPC to talk to the control system and ZMQ for retrieving the data stream.

WEPHA049	CERN Neutrino Cryogenic Control System Technology: From the WA10⁵ Test Facility to the NP04 and NP02 Platforms	controls, cryogenics, PLC, operation	1209
	M. Pezzetti, C.F. Fluder, R. Orlandi CERN, Geneva, Switzerland
	The CERN Neutrino Platform is CERN’s undertaking to foster fundamental research in neutrino physics at particle accelerators worldwide. In this contest CERN has constructed a series of cryogenic test facilities, first of this series is the 5 tons liquid Argon detector named WA10⁵, succeeded by the 800 tons liquid Argon cryostats designated as NP04 and NP02 detectors. The cryogenic control system of these experiments was entirely designed and constructed by CERN to operate 365 days a year in a safe way through all the different phases aimed to cool down and fill the cryostat until reaching nominal stable conditions . This paper describes the process control system design methodology, the off line validation and the operational commissioning including fault scenario handling. A systematic usage of advanced informatics tools, such as CERN/CPC tools, Git and Jenkins, used to ensure a smooth and systematic software development of the process, is presented. Finally, particular attention is given to the adoption of the CERN cryogenic technical standard solutions to enhance reliability, safety, and flexibility of the system working 24 hours a day

WEPHA060	Future Acquisition Architecture Investigations at Diamond	software, framework, data-acquisition, controls	1240
	K.A. Ralphs, J.W. Handford 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.

	J.P. Hucka, J. Fitzek, D. Ondreka, S. Pietri, B.R. Schlei, H. Weick GSI, Darmstadt, Germany J. Enders TU Darmstadt, Darmstadt, Germany
	Funding: Supported by BMBF (05P15RDFN1 and 05P19RDFN1) At the GSI facility, the LSA* framework from CERN is used to implement a new control system for accelerators and beam transfers. This was already completed and tested for the SIS18 accelerator. The implementation of experimental rings such as CRYRING and ESR is currently under development. In addition, the fragment separator FRS and - at a later stage - also the superconducting fragment separator Super-FRS at FAIR will be controlled within this framework. The challenge posed by the implementation of the control system for the FRS arises from the interaction of the beam with matter in the beamline and the beam’s associated energy loss. This energy loss is determined using input from ATIMA* and has been included into the code of the LSA framework. The developed control system solutions were tested in dry-runs and proven to control power supplies and actuators with the help of an out of framework solution. Additionally the current production version of the software and setting generator was simulated and benchmarked by comparison to older measurements. M. Lamont et al., LHC Project Note 368 H.

	O. Ivashkevych, M.C. Cowan, L.F. Flaks, D. Poshka, T. Smith BNL, Upton, New York, USA
	Funding: National Synchrotron Light Source, a U.S. Department of Energy (DOE) Office of Science User Facility operated by Brookhaven National Laboratory under Contract No. DE-AC02-98CH10886. 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. https://oksanagit.github.io/babyIOC https://github.com/areaDetector *https://www.udoo.org/

WEPHA075	EPICS Also for Small and Medium Sized Experiments	EPICS, controls, FEL, electron	1269
	H. Junkes FHI, Berlin, Germany
	The Max Planck Society (MPS) is now promoting the use of EPICS for data acquisition within its organization. An attempt is being made to establish an alternative to commercial systems. Not only the big experiments like radio telescopes, LIGO, accelerators and FELs will be supported, but also smaller to medium experiments. This will also benefit MPS users at beamlines of accelerators. In order to make EPICS also attractive for less IT-affine experimenters (besides physicists also chemists and biochemists), the first step is to revise the documentation, to create some dummy instructions, but also to develop, set up and test demonstration and production hardware. One focus at a later stage will be the use of the real-time operating system RTEMS. The poster shows the current status of the project and explains the planned further measures.

WEPHA091	Generalising the High-Level Geometry System for Reflectometry Instruments at ISIS	controls, neutron, EPICS, target	1300
	T. Löhnert, A.J. Long STFC/RAL/ISIS, Chilton, Didcot, Oxon, United Kingdom J.R. Holt Tessella, Abingdon, United Kingdom
	At the ISIS Pulsed Neutron and Muon Source, we in the Experiment Control Group are currently upgrading from the LabVIEW-based SECI instrument control system to the new IBEX control system* based on EPICS**. One class of instrument we have yet to migrate to the new system is reflectometers. These instruments require equipment to track the path of the neutron beam to high levels of precision over various experimental configurations, which results in a unique set of control system requirements. Since August 2018, we have been implementing a higher level geometry layer responsible for linking beamline components together and preserving experimental parameters such as the incident beam angle across different configurations. This layer is written as a Python server running on the instrument, which interfaces to the Channel Access protocol used by EPICS. This talk will provide an overview of the system architecture, specifically how it supports the design goal of making the system easy to extend and reconfigure while preserving the functionality of the existing solution, as well as an outlook on future plans for a more sophisticated motion control system. http://www.ni.com/en-gb/shop/labview.html https://iopscience.iop.org/article/10.1088/1742-6596/1021/1/012019/pdf *https://epics-controls.org/

WEPHA096	Timing Signal Distribution for Synchrotron Radiation Experiments Using RF Over White Rabbit	timing, synchrotron-radiation, radiation, synchrotron	1316
	T. Masuda JASRI, Hyogo, Japan
	In synchrotron radiation experiments, some measurements such as nuclear resonant scattering, time-of-flight, and time-resolved measurements necessitate an RF clock and fundamental revolution frequency (zero-address) signals synchronized with a storage ring. Currently, these timing signals are delivered directly over dedicated cables from an accelerator timing station to each experimental station. Considering the upcoming IoT era, it is preferable that these signals can be distributed over a network based on digital technology. Therefore, I am building a proof of concept system (PoCS) that will achieve distributions of the 508.58 MHz clock and the zero-address signals synchronized with the storage ring using RF over White Rabbit. The PoCS consists of a master node, which receives the RF clock and the zero-address signals from the accelerator, and two slave nodes which generate timing signals near experimental stations. Each node employs a SPEC* board and a new FMC DDS**. The slave node will be able to output the RF clock with the arbitrary division rate and phase after reproducing the 508.58 MHz clock. This paper will describe the achieved functions and performance of the PoCS. https://ohwr.org/project/wr-d3s https://ohwr.org/project/spec *https://ohwr.org/project/fmc-dac-600m-12b-1cha-dds

WEPHA102	A Software Suite for the Radiation Tolerant Giga-bit Transceiver - Slow Control Adapter	software, controls, detector, interface	1333
	P. Moschovakos, P.P. Nikiel, S. Schlenker CERN, Meyrin, Switzerland H. Boterenbrood NIKHEF, Amsterdam, The Netherlands A. Koulouris NTUA, Athens, Greece
	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.

	A new version of the beamline control application BSXCuBE (BioSAXS Customized Beamline Environment) designed to control BioSAXS experiments at the new ESRF Extremely Brilliant Source (EBS) is under development. The new application is implemented as a Web application and it is based on MXCuBE3 (Macromolecular Crystallography Customized Beamline Environment version 3) from which inherits the same technology stack and application structure. This approach allows for faster development and easier maintenance. The advances in architecture and the design of new features in BSXCuBE3 are intended to enhance the automation on BioSAXS beamlines and facilitate the integration of new sample setups, such as microfluidics. As for MXCuBE3, the access to the application from any web browser natively allows the execution of remote experiments. Moreover, the ergonomics of the interface further simplifies beamline operation even for non-experienced users. This work presents the current status of BSXCuBE3 and demonstrates how the development of MXCuBE3 has contributed to the construction of a BioSAXS application.

WEPHA124	CERN Accelerators Beam Optimization Algorithm	ISOL, controls, simulation, operation	1379
	E. Piselli, A. Akroh, S. Rothe CERN, Geneva, Switzerland K. Blaum, M. Door MPI-K, Heidelberg, Germany D. Leimbach IKP, Mainz, Germany
	In experimental physics, computer algorithms are used to make decisions to perform measurements and different types of operations. To create a useful algorithm, the optimization parameters should be based on real time data. However, parameter optimization is a time consuming task, due to the large search space. In order to cut down the runtime of optimization we propose an algorithm inspired by the numerical method Nelder-Mead. This paper presents details of our method and selected experimental results from high-energy (CERN accelerators) to low-energy (Penning-trap systems) experiments as to demonstrate its efficiency. We also show simulations performed on standard test functions for optimization.

WEPHA127	The IRRAD Proton Irradiation Facility Control, Data Management and Beam Diagnostic Systems: An Outlook of the Major Upgrades Beyond the CERN Long Shutdown 2	radiation, proton, controls, operation	1389

	Funding: This project has received funding from the European Union’s Horizon 2020 Research and Innovation program under Grant Agreement no. 654168. The IRRAD proton irradiation facility at CERN was built during the Long Shutdown 1 (LS1) to address the irradiation experiment needs of the community working for the High-Luminosity (HL) upgrade of the LHC. The present IRRAD is an upgrade of a historical service at CERN that, since the 90’s, exploits the high-intensity 24 GeV/c PS proton beam for radiation-hardness studies of detector, accelerator and semiconductor components and materials. During its first run (2015-2018), IRRAD provided a key service to the CERN community, with more than 2500 samples irradiated. IRRAD is operated via custom-made irradiation systems, beam diagnostics and data management tools. During the Long Shutdown 2 (LS2), IRRAD will undergo several upgrades in order to cope also with new requirements arising for projects beyond the HL-LHC. In this paper, we (1) describe the various hardware and software equipment developed for IRRAD, and (2) present the main challenges encountered during the first years of operation, which have driven most of the improvements planned for LS2 such as applying machine-learning techniques in the processing and real-time analysis of beam profile data.

WEPHA174	ADUVC - an EPICS Areadetector Driver for USB Video Class Devices	detector, EPICS, controls, monitoring	1492
	J. Wlodek Stony Brook University, Computer Science Department, Stony Brook, New York, USA K.J. Gofron BNL, Upton, New York, USA
	Most devices supported by EPICS areaDetector fall under one of two categories: detectors and cameras. Many of the cameras in this group can be classified as industrial cameras, and allow for fine control of exposure time, gain, frame rate, and many other image acquisition parameters. This flexibility can come at a cost however, with most such industrial cameras’ prices starting near one thousand dollars, with the price rising for cameras with more features and better hardware. While these prices are justified for situations that require a large amount of control over the camera, for monitoring tasks and some basic data acquisition the use of consumer devices may be sufficient while being far less cost-prohibitive. The solution we developed was to write an areaDetector driver for USB Video Class (UVC) devices, which allows for a variety of cameras and webcams to be used through EPICS and areaDetector, with most costing under $100.

WESH3002	Control System for Fast Components of Electron Beam Welding Machines	controls, EPICS, electron, real-time	1516
	A.V. Gerasev, P.B. Cheblakov BINP SB RAS, Novosibirsk, Russia
	Modern electron beam machines for different applications including welding, additive technologies and etc. consist of many different subsystems, which should be controlled and monitored. They could be divided by so-called fast and slow subsystems. Slow subsystems allow reaction time to be around couple of seconds that can be implemented using PC. Fast subsystems require time to be around hundreds of microseconds combined with flexible logic. We present an implementation of such fast system for mechanical moving platform and electron beam control. The core of this system is single board computer Raspberry Pi. We employed a technique of fast waveform generation using Raspberry Pi on-chip DMA to manipulate stepper motors. Raspberry Pi was equipped by external CAN controller to operate an electron beam via CAN DACs. Special software was developed including libraries for low- and high-level technical process control written in C and Rust; and in-browser graphical user interface over HTTP and WebSockets. Finally, we assembled our hardware inside standard 19-inch rack mount chassis and integrated our system inside experimental electron beam machine infrastructure.

Funding: This material is based upon work supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under contract number DE-AC05-00OR22725.
The Spallation Neutron Source at Oak Ridge National Laboratory is planning two major upgrades to the facility. The Proton Power Upgrade project, currently underway, will double the machine power from 1.4 to 2.8 MW by adding seven additional cryomodules and associated equipment. The Second Target Station project, currently in conceptual design, will construct a new target station effectively doubling the potential scientific output of the facility. This paper discusses the control system upgrades required to integrate these projects into the existing EPICS based control systems used for the machine and neutron instrument beamlines. While much of the control system can be replicated from existing solutions, some systems require new hardware and software. Operating two target stations simultaneously will require a new run permit system to safely manage beam delivery.

EPICS is mature in accelerator community. However, there are endeavors to improve existing control system software like Tango and EPICS 7 mainly driven by the needs of flexibility of the control system and the development of computer technology. This paper presents a new way of building a large experimental device control system using web technology instead of EPICS toolkit. The goal is to improve the interoperability of the control system allowing different component in the control system to talk to each other effortlessly. An abstraction of the control system is made. The control system components are abstracted into resources. The accessing of the resources is done via standard HTTP RESTful web API. HMI is based on HTML and JavaScript in browsers. Web Socket is used for event distribution. The main feature of this design is that all interfaces in the system are based on open web standards, which are interoperable among almost all kinds of devices. The paper also presents a software toolkit to build this kind of control system. A control system for a diagnostic on J-TEXT tokamak built using this toolkit will be presented.

The evolution of Software Control Systems introduced the usage of dynamically typed languages, like Python or Ruby, that helped Accelerator scientists to develop their own control algorithms on top of the standard control system. This new high-level layer of scientist-developed code is prone to continuous change and no longer restricted to fixed types and data structures as low-level control systems used to be. This provides great advantages for scientists but also big challenges for the control engineers, that must integrate this dynamic developments into existing systems like user interfaces, archiving or alarms.

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.

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.

SOLEIL, Gif-sur-Yvette, France

A new Nanoprobe system, which was originally developed in the scope of a collaboration with MAXIV (Sweden), has recently been tested and validated on the SWING beamline in Synchrotron SOLEIL. The aim of the project was to construct a Ptychography nano-imaging station. Initial steps were taken to provide a portable system capable of nanometric scans of samples with sizes ranging from the micrometer to fractions of a millimeter. Imaging was made possible by actuating a total of 16 Degrees Of Freedom (DOF) composed of a sample stage (3 DOF), a central stop stage (5 DOF), a Fresnel zone plate stage (5 DOF), as well as an order sorting aperture stage (3 DOF). These stages were actuated by an ensemble of piezo-driven and high-quality brushless motors, of which synchronized control (with kinematic modelling) was done using the Delta Tau platform. In addition, interferometry feedback was used for reconstruction purposes. Imaging results are promising: the system was able to resolve 40 nm measured with a Siemens star, the paper will describe the system and the achieved results.

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.

The ATLAS Technical Coordination Expert System is a tool for the simulation of the ATLAS experiment infrastructure that combines information from diverse areas such as detector control (DCS) and safety systems (DSS), gas, water, cooling, ventilation, cryogenics, and electricity distribution. It allows the planning of an intervention during technical stops and maintenance periods, and it is being used during the LS2 to provide an additional source of information for the planning of interventions. This contribution will describe the status of the Expert System and how it us used to provide information on the impact of an intervention based on the risk assessment models of fault tree analysis and principal component analysis.

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.

Improving User Information by Interfacing the Slow Control’s Log and Alarm Systems to a Flexible Chat Platform

Heidelberg University, Heidelberg, Germany

Research groups operating large experiments are often spread out around the globe, so that it can be a challenge to stay informed about current operations. We have therefore developed a solution to integrate a slow control system’s alarm and logging systems with the chat system used for communication between experimenters. This integration is not intended to replace a control screen containing the same information, but offers additional possibilities: - Instead of having to open the control system’s displays, which might involve setup work (VPN, remote desktop connections, …), a web interface or an app can be used to track important events in the system. - Messages can easily be filtered and routed to different recipients (individual persons or chat rooms). - Messages can be annotated and commented on. The system presented uses Apache Camel to forward messages received via JMS to Rocket. Chat. Since no binding to Rocket. Chat was available, this interface has been implemented. On the sending side, a C++ logging library that integrates with EPICS IOCs and interfaces with JMS has been designed.
For the Belle II PXD collaboration.

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.

Beamlines can benefit from the implementation of industrial robots in several ways: minimization of dead time, maximization of experimental throughput, and limitation of human presence during experimentation. Furthermore, the robots add flexibility in task management. The challenge for SOLEIL is to define a robotic standard, on both hardware and software, which is versatile enough to cover beamlines requirements, while being easy to implement, easy to use, and to maintain in operation. This paper will present the process of defining such a standard at SOLEIL, using 6 axis industrial robot arms. It will detail all aspects of this development, from market studies up to technical constraints. The specifications of the robots are aimed at addressing the most common technical constraints of beamlines, with a special care for mechanical properties. The robotic systems will be integrated into the Tango control system using a feature-based approach. This standard implementation is driven by two applications: picking and placing samples for powder diffraction on the CRISTAL beamline and positioning of a detector for x-rays coherent diffraction experiments on the NANOSCOPIUM beamline.

A 6 GeV high energy synchrotron radiation light source is being built near Beijing, China. The accelerator part contains a linac, a booster and a 1360 m circumference storage ring, and fourteen production beamlines for phase one. The control systems are EPICS based with integrated application and data platforms for the accelerators and beamlines. The number of devices and the complexity level of operation for such a machine is extremely high, therefore, a modern system design is vital for efficient operation of the machine. This paper reports the design, preliminary development and planned near-future work, especially the databases for quality assurance and application software platforms for high level applications.

NICA (Nuclotron-based Ion Collider fAcility) is a new accelerator complex designed at the Joint Institute for Nuclear Research (Dubna, Russia) to study properties of dense baryonic matter. BM@N (Baryonic Matter at Nuclotron) is the first experiment at the complex. It is an experimental setup in the fixed-target hall of the Nuclotron to perform a research program focused on the production of strange matter in heavy-ion collisions. MPD (Multipurpose Detector) is a detector for colliding beam experiments at the complex, and it is being developed to provide: efficient registration of the particles produced by heavy ion collisions; identification of particle type, charge and energy; reconstruction of vertices of primary interactions and the position of secondary particle production. Existing Slow Control Systems for BM@N experiment, assembling, and testing zones of MPD detectors are based on Tango Controls. They provide monitoring and control of diverse hardware for efficient data taking, stable operation of detectors and quality control of assembled modules. Current status and developments as well as future design and plans for MPD Slow Control System will be reported.

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.

Failure event and maintenance record based data collection systems have a long tradition in industry. Today, the particle accelerator community does not possess a common platform that permits storing and sharing reliability and availability information in an efficient way. In large accelerator facilities used for fundamental physics research, each machine is unique, the scientific culture, work organization, and management structures are often incompatible with a streamlined industrial approach. Other accelerator facilities enter the area of industrial process improvement, like medical accelerators due to legal requirements and constraints. The Heidelberg Ion Beam Therapy Center is building up a system for reliability and availability analysis, exploring the technical and organizational requirements for a community-wide information system on accelerator system and component reliability and availability. This initiative is part of the EU H₂020 project ARIES, started in May 2017. We will present the technical scope of the system that is supposed to access and obtain information specific to reliability statistics in ways not compromising the information suppliers and system producers.

We report on two latest updates of the RIKEN Radioactive Isotope Beam Factory (RIBF) control system. First, the successor of the existing beam interlock system (BIS) operated since 2006 was developed in 2019. As a first step, it covers a small part of the RIBF facility. The new interlock system is based on a programmable logic controller (PLC) and uses a Linux-based PLC-CPU on that the Experimental Physics and Industrial Control System (EPICS) programs can be executed in addition to a sequencer. By using two kinds of CPUs properly according to the speed required for each signal handled in the system, we succeeded in reducing the response time less than one third of the BIS in the performance test using prototype. Second, we plan to expand coverage of the alarm system. We have applied the Best Ever Alarm System Toolkit (BEAST) for several years in addition to the Alarm Handler mainly to vacuum components. We have tried to include the magnet power supplies but found difficulties in treating old power supplies having large fluctuations of read-out values of their excitation currents in an appropriate manner. Our trials to overcome this problem will be presented.

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 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.

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.

SLAC, Menlo Park, California, USA

When the LCLS-II project is complete, there will be three major Department of Energy (DOE) beam programs occupying the same 2-mile long accelerator tunnel, e.g. LCLS, LCLS-II and FACET-II. In addition to the geographical overlap, the number of beam loss monitors of all types has been also significantly expanded to detect power beam loss from all sources. All these factors contribute to highly complex Radiation Safety Systems (RSS) at SLAC. As RSS are subject to rigorous configuration control, and their outputs are permits directly related to beam production, even small faults can cause a long down time. As all beam programs at SLAC have the 95% beam availability target, the complex RSS’s contribution to overall beam availability and maintainability is an important subject worth detailed analysis. In this paper, we apply the dynamic system reliability engineering techniques to create the RSS reliability model for all three beam programs. Both qualitative and semi-quantitative approaches are used to identify the most critical common causes, the most vulnerable subsystem as well as the areas that require future design improvement for better maintainability.

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.

ALICE is the LHC experiment specifically devoted to the study of heavy-ion collisions. The Muon Forward Tracker (MFT) is one of the new detectors developed in the framework of the upgrade programs towards the LHC Run 3 starting from 2021. A Detector Control System (DCS) was developed for the MFT within the new framework of the upgraded ALICE central DCS. In this framework, detectors will deliver physics raw data as well as slow control data. The central DCS will be composed of an interface, named Alice Low level FRont-End Device (ALFRED), to convert high-level words within the DCS to low-level words which are sent to the detector FEE as commands. Used Supervisory Control And Data Acquisition (SCADA) is WinCC Open Architecture (OA). In addition, Joint Control Project Framework is installed to provide standard DCS solutions such as a Finite State Machine (FSM) commonly used by the LHC experiments. The FSM, as a base of the DCS hierarchy, was fully developed and successfully tested. A test bench of the MFT DCS was built as a minimal setup of the full DCS chain consisting of WinCC OA, ALFRED, a demonstration board of a DCS chip and a readout board. The latest status will be presented.

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.

Detectors and electronic components in High-Energy Physics experiments are nowadays often exposed to harsh radiation environments. Thus, to insure reliable operation over time, their radiation tolerance must be assessed beforehand through dedicated testing experiments in irradiation facilities. To prevent data loss and perform accurate experiments, these facilities need to rely upon a proper data management system. In prior work, we provided a formal description of the key concepts involved in the data management of irradiation experiments using an ontology (IEDM)*. In this work, we show how this formalisation effort has a practical by-product via the introduction of an ontology-based methodology for the automatic generation of web applications, using IEDM as a use case. Moreover, we also compare this IEDM-generated web application to the IRRAD Data Manager (IDM), the manually developed web application used for the data handling of the CERN Proton Irradiation facility (IRRAD). Our approach should allow irradiation facility teams to gain access to state-of-the-art data management tools without incurring significant software development effort.

Recently, there are strong demands on open data to promote data science like material informatics. At SPring-8, we have been operated data transfer system for open data of XAFS measurements since 2013* with the second in the world for amount data**. However, it was difficult to satisfy demands such as generic uses in experimental stations and data federation with other facilities. To overcome these, we newly developed data transfer system BENTEN. BENTEN provides easy-to-use and unified interface with REST API for data access from both inside and outside SPring-8. At SPring-8, proposal number is assigned for each experiment and members in the proposal are defined in DB. BENTEN can also realize restricted data access with the members using authentication and the DB. Data registration was performed with metadata such as experimental conditions and samples. Various metadata in the experiments can be easily defined. To achieve flexible data access with full-text search, we used Elasticsearch as metadata store. We began operation of BENTEN and open access of XAFS data since March this year. We plan to utilize BENTEN to promote open data and data science also with other experimental data.

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. Various architectures provided by public clouds enable advanced systems to develop quickly and effectively. Our cloud-based infrastructure comprises services for experimental monitoring, data download and data analysis, using architectures, such as object storage, event-driven server-less computing, and virtual desktop infrastructure (VDI). Facility users can access this infrastructure using a web browser and a VDI client. This contribution reports the current status of the remote access infrastructure.

This paper discloses the integration, in a 180 nm CMOS technology, of a 4-channel delay generator dedicated to synchronization down to a few ps. The delay generation principle relies on the linear charge of a capacitor triggered by the input pulse. The output pulse generation occurs when the capacitor voltage exceeds a threshold voltage. The delay full scale is automatically set to match the period of the master clock, ranging from 5-7 ns, with the help of an embedded calibration circuit. The delay value is controlled with the help of a 14-bit DAC setting the threshold voltage, which leads to a 400 fs delay step. Among other features, the chip embeds a combination mode of either 2 or 4 channels to output narrow width pulses. The chip is fully compliant with LVDS, LVPECL and CML differential input pulses and outputs LVPECL pulses. The chip has been fully characterized over temperature (0 to 60 °C) and supply voltage (± 10%). The chip is compliant with pulse repetition frequencies up to 20 MHz. The measured INL is 100 LSB and the RMS jitter is 1.8 ps. The power consumption has been measured to 350 mW for 4 active channels.

The aim of the Laser Megajoule facility (LMJ) is to deliver more than 1 MJ of laser energy to targets for high energy density physics experiments. In association with Greenfield Technology, we developed a specific timing system to synchronize the 176 laser beams on the target with a precision better than 40 ps rms and to trigger and mark plasma diagnostics. The final architecture, settled and used since three years, is based on a master oscillator that sends a clock with serial data through a fiber-optic network, allowing to synchronize more than 500 delay generators spread over the large LMJ facility. The settings of each laser beam and the various experiments require different sampling rates (multi to single shot) and 16 groups for coactivity. Three kinds of delay generators, electrical and optical, are designed for standard precision (<150 ps jitter) and the third is designed for high precision. Each output deliver trigger or fiducial signals with jitter down to 5 ps and peak-to-peak wander less than 10 ps over a week. Test performance of this LMJ timing system is in progress all over the LMJ facility. Besides it will be installed on the petawatt laser (PETAL) this year.

The data format and volume at LCLS requires significant computing expertise which not all user groups can provide. We will describe the path to and current status of a Python module that enables user groups to translate and reduce their data into a format that they can easily work with. The package is developed in Python and uses the standard LCLS data analysis framework. It encapsulates knowledge of the standard beam line components and adds convenient ways to reduce the data of larger detectors. Both an event-based (best for small event sizes) and a binned approach which is able to handle larger data as megapixel size detectors are simple to setup. MPI is used for fast turn around, enabling close to real time feedback necessary to make decisions of how to use the limited amount of beam time. Jupyter notebooks are provided to demonstrate some of the available options and can serve as a convenient quick start for fast turn around analysis.

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

interface, software, neutron, status

M.J. Clarke, G.C. Murphy, R. Nørager, T.S. Richter
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.

The importance of usability and easy-to-use user interfaces (UI) have been recognized across many domains. However, the user-friendliness of scientific experiment control systems often lags behind industry standards in the flourishing user experience (UX) field. Scientific control systems can certainly benefit from these new UX research methods and approaches. Recent instrument control system upgrade projects at the SNS and HFIR facilities at Oak Ridge National Laboratory demonstrate the effectiveness of UX focused development work, and further reveal the need for more utilization of such techniques coming from the UX field. The ongoing control system upgrades are targeting the key facility-level priority of higher scientific productivity, and UX is one of the important tools to help us achieve this priority. We will highlight research methods and practices, introduce our findings and deliverables, and share challenges and lessons learned in applying UX methods to scientific control systems.

Roadmap to 100 Hz DAQ at SwissFEL: Experiences and Lessons Learned

FEL, operation, timing, controls

909

PSI, Villigen PSI, Switzerland

Providing reliable and performant Data Acquisition System (DAQ) at Free Electron Lasers (FELs) is a challenging and complex task due to the inherent characteristics of a pulsed machine and consequent need of beam synchronous shot-to-shot DAQ, which enables correlation of collected data associated with each FEL pulse. We will focus on experiences gathered during the process of moving towards 100 Hz operation at SwissFEL from the perspective of beam synchronous DAQ. Given the scarce resources and challenging deadlines, a lot of efforts went into managing conflicting stakeholder expectations and priorities and into allocation of time for operation support and maintenance tasks on one side and time for design and development tasks on the other side. The technical challenges we encountered have shown a great importance of having proper requirements in the early phase, a well thought system design concept, which considers all subsystems in the DAQ chain, and a well-defined test framework for validation of recorded beam synchronous data.

CERN, Geneva, Switzerland

The ALICE Experiment at CERN LHC (Large Hadron Collider) is undertaking during Long Shutdown 2 in 2019-2020 a major upgrade, which includes a new computing system called O² (Online-Offline). To ensure the efficient operation of the upgraded experiment along with its newly designed computing system, a reliable, high performance and automated experiment control system is being developed with the goal of managing all O² synchronous processing software, and of handling the data taking activity by interacting with the detectors, the trigger system and the LHC. The ALICE Experiment Control System (AliECS) is a distributed system based on state of the art cluster management and microservices which have recently emerged in the distributed computing ecosystem. Such technologies will allow the ALICE collaboration to benefit from a vibrant and innovating open source community. This communication illustrates the AliECS architecture. It provides an in-depth overview of the system’s components, features and design elements, as well as its performance. It also reports on the experience with AliECS as part of ALICE Run 3 detector commissioning setups.

CERN, Meyrin, Switzerland

The Industrial Controls Frameworks, JCOP and UNICOS, have been employed to develop hundreds of critical controls applications in multiple domains like the detector control system, accelerator complex (cryogenics, powering, interlocks) or technical infrastructure, leading to an unprecedented level of homogeneity. These frameworks, used by a thousand of developers worldwide, will now undergo a major consolidation and re-engineering effort to prepare them for the new challenges of the next 20 years in the HL-LHC era, and streamline their maintenance. The paper presents the challenges that will be faced during this project due to the breadth of technological stack and large code-base contributed over two decades by numerous authors. Delivery of innovation induced by evolution of technologies and refactoring of the ageing code must be done in a way that ensures backward-compatibility for existing systems. The vision and the current state of the frameworks is discussed, alongside the main deliveries planned in the medium term. Lessons learnt, optimizations of processes to make best use of available resources and efforts towards open-source licensing of the frameworks are also presented.

Data Analysis Infrastructure for Diamond Light Source Macromolecular & Chemical Crystallography and Beyond

The Diamond Light Source data analysis infrastructure, Zocalo, is built on a messaging framework. Analysis tasks are processed by a scalable pool of workers running on cluster nodes. Results can be written to a common file system, sent to another worker for further downstream processing and/or streamed to a LIMS. Zocalo allows increased parallelization of computationally expensive tasks and makes the use of computational resources more efficient. The infrastructure is low-latency, fault-tolerant, and allows for highly dynamic data processing. Moving away from static workflows expressed in shell scripts we can easily re-trigger processing tasks in the event that an issue is found. It allows users to re-run tasks with additional input and ensures that automatically and manually triggered processing results are treated equally. Zocalo was originally conceived to cope with the additional demand on infrastructure by the introduction of Eiger detectors with up to 18 Mpixels and running at up to 560 Hz framerate on single crystal diffraction beamlines. We are now adapting Zocalo to manage processing tasks for ptychography, tomography, cryo-EM, and serial crystallography workloads.

The past decade has seen great advances in web technology, making the browser the de-facto platform for many user applications. Advances in JavaScript, and innovations such as TypeScript, have enabled developers to build large scale applications for the web without sacrificing code maintainability. However, this rapid growth has also been accompanied by turbulence. AngularJS arrived and saw widespread adoption only to be supplanted by Angular 2+ a few years later; meanwhile other JavaScript-based languages and developer tools have proliferated. At the National Ignition Facility (NIF), the Shot Setup Tool (SST) is a large web-based tool for configuring experiments on the NIF that is being developed to replace legacy Java Swing application. We will present our experience in building SST during this turbulent time, including how we have leveraged TypeScript to greatly enhance code readability and maintainability in a multi-developer team, and our current effort to incrementally migrate from AngularJS to React.

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.

Reliability, availability and maintainability determine whether or not a large-scale accelerator system can be operated in a sustainable, cost-effective manner. Beam transfer equipment (e.g. kicker magnets) has potentially significant impact on the global performance of a machine complex. Identifying root causes of malfunctions is currently tedious, and will become infeasible in future systems due to increasing complexity. Machine Learning could automate this process. For this purpose a collaboration between CERN and KU Leuven was established. We present an anomaly detection pipeline which includes preprocessing, detection, postprocessing and evaluation. Merging data of different, asynchronous sources is one of the main challenges. Currently, Gaussian Mixture Models and Isolation Forests are used as unsupervised detectors. To validate, we compare to manual e-logbook entries, which constitute a noisy ground truth. A grid search allows for hyper-parameter optimization across the entire pipeline. Lastly, we incorporate expert knowledge by means of semi-supervised clustering with COBRAS.

Nowadays there is a growing need for user friendly workflow editors in all fields of scientific research. A special interest group is present at big physics research facilities where instrumentation is mostly controlled by a robust, and reliable low level control software solution. Different types of specific experiments using predetermined automated protocols and on-line data processing with real-time feedback require a more flexible and abstract high level control system*. Beside flexibility and dynamism, easy usability is also required for researchers collaborating from several different fields. Tentatively, to test the ease and flexible usability, the Kepler workflow-engine was integrated with Tango**. It enables researchers to automate and document experiment protocols without any programming skill. The X-ray crystallography laboratory at the Biological Research Center of Hungarian Academy of Science (BRC) has implemented an example crystallographic workflow to test the integrated system. This development was performed in cooperation with ELI-ALPS.

The experimental capabilities at the MAX IV synchrotron consists of 17 beamlines at full capacity. Each beamline puts different requirements on the control system in terms of data acquisition, high performance, data volume, pre-processing needs, and fast experiment feedback and online visualization. Therefore, high demands are put on the data management systems, and the reliability and performance of these systems has a big impact on the overall success of the facility. At MAX IV we have started the DataStaMP (Data Storage and Management Project) with the aim of providing a unified and reliable solution for all data sources in our facility. This work presents the control system aspects of the project. It is initially aimed at providing data management solution for a selected number of detectors and beamlines. It is developed in a modular and scalable architecture and combines several programming languages and frameworks. All the software runs in a dedicated cluster and communicates with the experimental stations through high performance networks, using gRPC to talk to the control system and ZMQ for retrieving the data stream.

The CERN Neutrino Platform is CERN’s undertaking to foster fundamental research in neutrino physics at particle accelerators worldwide. In this contest CERN has constructed a series of cryogenic test facilities, first of this series is the 5 tons liquid Argon detector named WA10⁵, succeeded by the 800 tons liquid Argon cryostats designated as NP04 and NP02 detectors. The cryogenic control system of these experiments was entirely designed and constructed by CERN to operate 365 days a year in a safe way through all the different phases aimed to cool down and fill the cryostat until reaching nominal stable conditions . This paper describes the process control system design methodology, the off line validation and the operational commissioning including fault scenario handling. A systematic usage of advanced informatics tools, such as CERN/CPC tools, Git and Jenkins, used to ensure a smooth and systematic software development of the process, is presented. Finally, particular attention is given to the adoption of the CERN cryogenic technical standard solutions to enhance reliability, safety, and flexibility of the system working 24 hours a day

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.

At the GSI facility, the LSA* framework from CERN is used to implement a new control system for accelerators and beam transfers. This was already completed and tested for the SIS18 accelerator. The implementation of experimental rings such as CRYRING and ESR is currently under development. In addition, the fragment separator FRS** and - at a later stage - also the superconducting fragment separator Super-FRS at FAIR will be controlled within this framework. The challenge posed by the implementation of the control system for the FRS arises from the interaction of the beam with matter in the beamline and the beam’s associated energy loss. This energy loss is determined using input from ATIMA*** and has been included into the code of the LSA framework. The developed control system solutions were tested in dry-runs and proven to control power supplies and actuators with the help of an out of framework solution. Additionally the current production version of the software and setting generator was simulated and benchmarked by comparison to older measurements.

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.

The Max Planck Society (MPS) is now promoting the use of EPICS for data acquisition within its organization. An attempt is being made to establish an alternative to commercial systems. Not only the big experiments like radio telescopes, LIGO, accelerators and FELs will be supported, but also smaller to medium experiments. This will also benefit MPS users at beamlines of accelerators. In order to make EPICS also attractive for less IT-affine experimenters (besides physicists also chemists and biochemists), the first step is to revise the documentation, to create some dummy instructions, but also to develop, set up and test demonstration and production hardware. One focus at a later stage will be the use of the real-time operating system RTEMS. The poster shows the current status of the project and explains the planned further measures.

At the ISIS Pulsed Neutron and Muon Source, we in the Experiment Control Group are currently upgrading from the LabVIEW*-based SECI instrument control system to the new IBEX control system** based on EPICS***. One class of instrument we have yet to migrate to the new system is reflectometers. These instruments require equipment to track the path of the neutron beam to high levels of precision over various experimental configurations, which results in a unique set of control system requirements. Since August 2018, we have been implementing a higher level geometry layer responsible for linking beamline components together and preserving experimental parameters such as the incident beam angle across different configurations. This layer is written as a Python server running on the instrument, which interfaces to the Channel Access protocol used by EPICS. This talk will provide an overview of the system architecture, specifically how it supports the design goal of making the system easy to extend and reconfigure while preserving the functionality of the existing solution, as well as an outlook on future plans for a more sophisticated motion control system.

Timing Signal Distribution for Synchrotron Radiation Experiments Using RF Over White Rabbit

1316

T. Masuda
JASRI, Hyogo, Japan

In synchrotron radiation experiments, some measurements such as nuclear resonant scattering, time-of-flight, and time-resolved measurements necessitate an RF clock and fundamental revolution frequency (zero-address) signals synchronized with a storage ring. Currently, these timing signals are delivered directly over dedicated cables from an accelerator timing station to each experimental station. Considering the upcoming IoT era, it is preferable that these signals can be distributed over a network based on digital technology. Therefore, I am building a proof of concept system (PoCS) that will achieve distributions of the 508.58 MHz clock and the zero-address signals synchronized with the storage ring using RF over White Rabbit*. The PoCS consists of a master node, which receives the RF clock and the zero-address signals from the accelerator, and two slave nodes which generate timing signals near experimental stations. Each node employs a SPEC** board and a new FMC DDS***. The slave node will be able to output the RF clock with the arbitrary division rate and phase after reproducing the 508.58 MHz clock. This paper will describe the achieved functions and performance of the PoCS.

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.

A new version of the beamline control application BSXCuBE (BioSAXS Customized Beamline Environment) designed to control BioSAXS experiments at the new ESRF Extremely Brilliant Source (EBS) is under development. The new application is implemented as a Web application and it is based on MXCuBE3 (Macromolecular Crystallography Customized Beamline Environment version 3) from which inherits the same technology stack and application structure. This approach allows for faster development and easier maintenance. The advances in architecture and the design of new features in BSXCuBE3 are intended to enhance the automation on BioSAXS beamlines and facilitate the integration of new sample setups, such as microfluidics. As for MXCuBE3, the access to the application from any web browser natively allows the execution of remote experiments. Moreover, the ergonomics of the interface further simplifies beamline operation even for non-experienced users. This work presents the current status of BSXCuBE3 and demonstrates how the development of MXCuBE3 has contributed to the construction of a BioSAXS application.

In experimental physics, computer algorithms are used to make decisions to perform measurements and different types of operations. To create a useful algorithm, the optimization parameters should be based on real time data. However, parameter optimization is a time consuming task, due to the large search space. In order to cut down the runtime of optimization we propose an algorithm inspired by the numerical method Nelder-Mead. This paper presents details of our method and selected experimental results from high-energy (CERN accelerators) to low-energy (Penning-trap systems) experiments as to demonstrate its efficiency. We also show simulations performed on standard test functions for optimization.

Funding: This project has received funding from the European Union’s Horizon 2020 Research and Innovation program under Grant Agreement no. 654168.
The IRRAD proton irradiation facility at CERN was built during the Long Shutdown 1 (LS1) to address the irradiation experiment needs of the community working for the High-Luminosity (HL) upgrade of the LHC. The present IRRAD is an upgrade of a historical service at CERN that, since the 90’s, exploits the high-intensity 24 GeV/c PS proton beam for radiation-hardness studies of detector, accelerator and semiconductor components and materials. During its first run (2015-2018), IRRAD provided a key service to the CERN community, with more than 2500 samples irradiated. IRRAD is operated via custom-made irradiation systems, beam diagnostics and data management tools. During the Long Shutdown 2 (LS2), IRRAD will undergo several upgrades in order to cope also with new requirements arising for projects beyond the HL-LHC. In this paper, we (1) describe the various hardware and software equipment developed for IRRAD, and (2) present the main challenges encountered during the first years of operation, which have driven most of the improvements planned for LS2 such as applying machine-learning techniques in the processing and real-time analysis of beam profile data.

Most devices supported by EPICS areaDetector fall under one of two categories: detectors and cameras. Many of the cameras in this group can be classified as industrial cameras, and allow for fine control of exposure time, gain, frame rate, and many other image acquisition parameters. This flexibility can come at a cost however, with most such industrial cameras’ prices starting near one thousand dollars, with the price rising for cameras with more features and better hardware. While these prices are justified for situations that require a large amount of control over the camera, for monitoring tasks and some basic data acquisition the use of consumer devices may be sufficient while being far less cost-prohibitive. The solution we developed was to write an areaDetector driver for USB Video Class (UVC) devices, which allows for a variety of cameras and webcams to be used through EPICS and areaDetector, with most costing under $100.

Modern electron beam machines for different applications including welding, additive technologies and etc. consist of many different subsystems, which should be controlled and monitored. They could be divided by so-called fast and slow subsystems. Slow subsystems allow reaction time to be around couple of seconds that can be implemented using PC. Fast subsystems require time to be around hundreds of microseconds combined with flexible logic. We present an implementation of such fast system for mechanical moving platform and electron beam control. The core of this system is single board computer Raspberry Pi. We employed a technique of fast waveform generation using Raspberry Pi on-chip DMA to manipulate stepper motors. Raspberry Pi was equipped by external CAN controller to operate an electron beam via CAN DACs. Special software was developed including libraries for low- and high-level technical process control written in C and Rust; and in-browser graphical user interface over HTTP and WebSockets. Finally, we assembled our hardware inside standard 19-inch rack mount chassis and integrated our system inside experimental electron beam machine infrastructure.

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.

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.

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.

Recently, by using deep learning methods, computers are able to surpass or come close to matching human performance on image analysis and pattern recognition. This advanced method could also help interpreting data from neutron scattering experiments. Those data contain rich scientific information about structure and dynamics of materials under investigation, and deep learning could help researchers better understand the link between experimental data and materials properties. We applied deep learning techniques to scientific neutron scattering data. This is a complex problem due to the multi-parameter space we have to deal with. We have used a convolutional neural network-based model to evaluate the quality of experimental neutron scattering images, which can be influenced by instrument configuration, sample and sample environment parameters. Sample structure can be deduced during data collection that can be therefore optimized. The neural network model can predict the experimental parameters to properly setup the instrument and derive the best measurement strategy. This results in a higher quality of data obtained in a shorter time, facilitating data analysis and interpretation.

PDF beamline is a new addition to Diffraction and In Situ Scattering program. Its state-of-the-art end-station gantry system has two detector stages and one sample environment with 3 m travel rated for 200 kg each. Detectors and environment stages move with 300 mm/s. Linear Brushless DC motors are controlled by Geo Brick LV Delta Tau motor-controller. Stages are equipped with absolute encoders and proximity sensors to avoid collisions. Control system slows the stages down when proximity switches are activated and moves 300 mm/s otherwise. A complex controls and safety system with many custom features is required to provide the full functionality of the gantry system and to protect equipment and users. An optics condition module located upstream of the gantry system contain beam defining slits, a fast shutter that is synchronized with detector frame rate, an alignment LASER, and an X-ray Energy Calibration System. The controls system of the OCM supports automatic operation of the ECS followed by unexpected beam dumps to recalibrate the X-ray wavelength. This contribution will discuss the details of the control system design, implementation, challenges, and first user experience.
