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

MOBPP05	Dynamic Control Systems: Advantages and Challenges	controls, TANGO, experiment, 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.

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

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

MOMPR002	Improving User Information by Interfacing the Slow Control’s Log and Alarm Systems to a Flexible Chat Platform	controls, GUI, operation, experiment	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.

	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.

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

MOPHA011	Improving Gesture Recognition with Machine Learning: A Comparison of Traditional Machine Learning and Deep Learning	network, GUI, real-time, controls	214
	R. Bacher DESY, Hamburg, Germany
	Meaningful gesturing is important for an intuitive human-machine communication. This paper deals with methods suitable for identifying different finger, hand and head movements using supervised machine learning algorithms. On the one hand it discusses an implementation based on the k-nearest neighbor classification algorithm (traditional machine learning approach). On the other hand it demonstrates the classification potential of a convolutional neural network (deep learning approach). Both methods are capable of distinguishing between fast and slow, short and long, up and down, or right and left linear as well as clockwise and counterclockwise circular movements. The details of the different methods with respect to recognition accuracy and performance will be presented.

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

MOPHA066	Electronics for LCLS-II Beam Containment System Shut-off	PLC, electron, electronics, linac	366
	R.A. Kadyrov, D.G. Brown, E.P. Chin, C.I. Clarke, M. Petree, E. Rodriguez, F. Tao SLAC, Menlo Park, California, USA
	LCLS-II is a new FEL which is under construction at SLAC National Accelerator Laboratory. Its superconducting electron linac is able to produce up to 1.2 MW of beam power. Beam Containment System (BCS) is employed to limit the beam power and prevent excessive radiation in case of electron beam loss or FEL breach. Fast and slow shut-off paths are designed for devices with different response requirements. The system is required to shut-off the beam within 200 µs for some of the fast sensors. Fast path is based on custom electronic designs, and slow path leverages industrial safety-rated PLC hardware. The system spans for 4 km of LCLS-II and combines inputs from about 150 sensors of different complexity. Architecture is based on multiple levels starting with summing sensor inputs locally and to converting them into permits for the shut-off devices. Each level is implemented redundantly. Automated test and manual tests at all levels are implemented in the system. System architecture, electronics design and cable plant challenges are presented below.

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

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

MOPHA109	Python Based Application for Beam Current Transformer Signal Analysis	electron, GUI, controls, electronics	473
	M.C. Paniccia, D.M. Gassner, A. Marusic, A. Sukhanov BNL, Upton, New York, USA
	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-SC0012704 with the U.S. Department of Energy. There are a variety of beam current transformers that are used at all accelerator facilities for current and bunch charge measurements. Transformer signals are traditionally measured using integrator electronics followed by a digitizer. However, integrator circuits have a limited bandwidth and are susceptible to noise. By directly digitizing the output of the transformer, the signal bandwidth is limited only by the transformer characteristics and the digitizing platform. Digital integration and filtering can then easily be applied to reduce noise resulting in an overall improvement of the beam parameter measurements. This paper describes a Python-based application that performs the filtering and integration of a current transformer pulse that has been directly digitized by an oscilloscope.

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

MOPHA118	Improving Alarm Handling for the TI Operators by Integrating Different Sources in One Alarm Management and Information System	framework, monitoring, database, controls	502
	M. Bräger, M. Bouzas Reguera, U. Epting, E. Mandilara, E. Matli, I. Prieto Barreiro, M.P. Rafalski CERN, Geneva, Switzerland
	CERN uses a central alarm system to monitor its complex technical infrastructure. The Technical Infrastructure (TI) operators must handle a large number of alarms coming from several thousand equipments spread around CERN. In order to focus on the most important events and improve the time required to solve the problem, it is necessary to provide extensive helpful information such as alarm states of linked systems, a geographical overview on a detailed map and clear instructions to the operators. In addition, it is useful to temporarily inhibit alarms coming from equipment during planned maintenance or interventions. The tool presents all necessary information in one place and adds simple and intuitive functionality to ease the operation with an enhanced interface.

MOPHA121	Generic Data Acquisition Interfaces and Processes in Sardana	controls, experiment, hardware, software	506

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.

MOPHA135	PyDM - Extension Points	framework, EPICS, controls, factory	539
	H.H. Slepicka, M.L. Gibbs SLAC, Menlo Park, California, USA
	PyDM (Python Display Manager) is a Python and Qt-based framework for building user interfaces for control systems providing a no-code, drag-and-drop system to make simple screens, as well as a straightforward Python framework to build complex applications. PyDM developers and users can easily create complex applications using existing Python packages such as NumPy, SciPy, Scikit-learn and others. With high level interfaces for data plugins and external tools, PyDM can be extended with new widgets, integration with facility-specific tools (electronic log books, data logger viewers, et cetera) as well as new data sources (EPICS, Tango, ModBus, Web Services, etc) without the need to recompile or change the PyDM internal source.

	The detection of beam loss events in accelerators is an important task for machine and personal protection, and for optimization of beam trajectory. An optical beam loss monitor (oBLM) being developed by the Cockcroft Institute at Daresbury Laboratory required integration with the rest of the controls and timing system of the site’s electron accelerator, CLARA (Compact Linear Accelerator for Research and Applications). [1] This paper presents the design and implementation of an inexpensive solution using a Domino Ring Sampling device from PSI. Signals from the oBLM are acquired and can be processed to resolve beam loss events to a resolution of 0.2 m.

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

MOPHA152	Use of Multi-Network Fieldbus for Integration of Low-Level Intelligent Controller Within Control Architecture of Fast Pulsed System at CERN	controls, network, Ethernet, FPGA	589
	N. Voumard, C. Boucly, M.P. Pimentel, L. Strobino, P. Van Trappen CERN, Geneva, Switzerland
	Fieldbuses and Industrial Ethernet networks are extensively used for the control of fast-pulsed magnets at CERN. With the ongoing trend to develop increasingly more complex low-level intelligent controllers near to the actuators and sensors, the flexibility to integrate these within different control architectures grows in importance. In order to reduce development efforts and keep the fieldbus choice open, a multi-network field-bus technology has been selected for the network interfacing part of the controllers. Such an approach has been successfully implemented for several projects such as the development of high voltage capacitor chargers/dischargers, the surveillance of floating solid-state switch and the monitoring of a power triggering system that, today, are interfaced either to PROFIBUS-DP or PROFINET networks. The integration of various fieldbus interfaces within the controller and the required embedded software/gateware to manage to network communication are presented. The gain in flexibility, modularity and openness obtained through this approach is also reviewed.

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

	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.

	J.M. Zhou, A.L. Li, K.N. Li, C.H. Peng, J. Zheng CIAE, Beijing, People’s Republic of China
	A linear superconducting accelerator is being constructed in our institute. Its vacuum control system should be convenient and reliable. We intend to concentrate the control of each vacuum unit into a control box that implement the simple hard interlocking logic and the final action output of the vacuum device and the complete interlocking logic between the vacuum devices is realized in the PLC. Operators can perform local operation through the front panel of the control box or remotely control through the computer by switching the local/remote switch. In addition, the control flow of vacuum extraction and the protection flow when leakage occurs are also given in this paper.

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

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

MOSH4002	A Cloud Based Framework for Advanced Accelerator Controls	controls, EPICS, operation, framework	655
	J.P. Edelen, M.V. Keilman, P. Moeller, R. Nagler RadiaSoft LLC, Boulder, Colorado, USA
	Funding: This material is based upon work supported by the U.S. Department of Energy, Office of Science, Office of Nuclear Physics under Award Number DE-SC0019682. Modern particle accelerator facilities generate large amounts of data and face increasing demands on their operational performance. As the demand on accelerator operations increases so does the need for automated tuning algorithms and control to maximize uptime with reduced operator intervention. Existing tools are insufficient to meet the broad demands on controls, visualization, and analysis. We are developing a cloud based toolbox featuring a generic virtual accelerator control room for the development of automated tuning algorithms and the analysis of large complex datasets. This framework utilizes tracking codes combined with with algorithms for machine drift, low-level control systems, and other complications to create realistic models of accelerators. These models are directly interfaced with advanced control toolboxes allowing for rapid prototyping of control algorithms. Additionally, our interface provides users with access to a wide range of Python-based data analytics libraries for the study and visualization of machine data. In this paper, we provide an overview of our interface and demonstrate its utility on a toy accelerator running on EPICS.

TUBPL01	Automatic Web Application Generation From an Irradiation Experiment Data Management Ontology (IEDM)	radiation, experiment, 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.

TUBPL06	Energy Consumption Monitoring With Graph Databases and Service Oriented Architecture	database, network, monitoring, operation	719
	A. Kiourkos, S. Infante, K.S. Seintaridis CERN, Meyrin, Switzerland
	CERN is a major electricity consumer. In 2018 it consumed 1.25 TWh, 1/3 the consumption of Geneva. Monitoring of this consumption is crucial for operational reasons but also for raising awareness of the users regarding energy utilization. This monitoring is done via a system, developed internally and is quite popular within the CERN community therefore to accommodate the increasing requirements, a migration is underway that utilizes the latest technologies for data modeling and processing. We present the architecture of the new energy monitoring system with an emphasis on the data modeling, versioning and the use of graphs to store and process the model of the electrical network for the energy calculations. The algorithms that are used are presented and a comparison with the existing system is performed in order to demonstrate the performance improvements and flexibility of the new approach. The system embraces the Service Oriented Architecture principles and we illustrate how these have been applied in its design. The different modules and future possibilities are also presented with an analysis of their strengths, weaknesses, and integration within the CERN infrastructure.

TUCPL03	The LMJ Target Diagnostics Integration	diagnostics, target, controls, software	767
	S. Tranquille-Marques, P. Prunet CEA, LE BARP cedex, France
	The French Laser Megajoule (LMJ) is, behind the US NIF, the second largest inertial fusion facility in the World. The main activity of this facility is the acquisition of several physical phenomena as neutron, gamma, X rays produced by the indirect attack of hundreds of high power laser beams on targets through measurement devices called "target diagnostics". More than 30 diagnostics will be installed and driven in a huge and complex integrated computer control system. All this Targets Diagnostics arrived one at a time, each one with its particularity and complexity. The Tango Architecture and Panorama are used for the command control of these equipment. The aim of this paper is first, to introduce how Targets Diagnostics are progressively integrated in the command control. We will then see how Targets Diagnostics managed to cohabit even if they are in different phases of their integration. The paper concludes how Target Diagnostics are configured and computer-driven during all the shot sequence.

	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.

TUCPR04	Improving User Experience in Complex Systems	experiment, 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/

	Funding: Argonne National Laboratory’s work was supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under contract DE-AC02-06CH11357 APS Upgrade multi-bend achromat accelerator (MBA) uses state-of-the-art embedded controllers coupled to various technical subsystems. These controllers have the capability to collect large amounts of fast data for statistics, diagnostics, or fault recording. At times, continuous real-time acquisition of this data is preferred, which presents a number of challenges that must be considered early on in the design; such as network architecture, data management and storage, real-time processing, and impact on normal operations. The design goal is selectable acquisition of turn-by-turn BPM data, together with additional fast diagnostics data. In this paper we discuss engineering specifications and the design of the MBA Data Acquisition System (DAQ). This system will interface with several technical subsystems to provide time-correlated and synchronously sampled data acquisition for commissioning, troubleshooting, performance monitoring and fault detection. Since most of these subsystems will be new designs for the MBA, defining the functionality and interfaces to the DAQ early in the development will ensure the necessary components are included in a consistent and systematic way.

	The CLARA experiment at the STFC, Daresbury laboratory has just completed its first successful exploitation period. The CLARA controls system is being rapidly deployed as CLARA enters its next development phase and our current infrastructure is becoming hard to maintain. Virtualization of the server infrastructure will allow the rapid deployment, recovery and testing of systems infrastructure. This talk will review our experience of migrating several key services and IOCs to a virtualized environment. KVM and LXD have been evaluated against our current system and Ansible has been used to automate many tasks that were normally done by hand. The Archiver Appliance is being exploited beyond its original deployment and is a critical component of several analysis tool-chains. Virtualization allows development, maintenance and deployment of the archiver without disrupting its users. Virtualization is also used to manage the CLARA Virtual Accelerator. The Virtual Accelerator can now run with many instances proving useful for scientists. Originally, it was limited to one instance per server.

WEAPP01	Old and New Generation Control Systems at ESA	controls, operation, ECR, monitoring	859
	M. Pecchioli ESA/ESOC, Darmstadt, Germany
	Traditionally Mission Control Systems for spacecraft operated at the European Space Operations Centre (ESOC) have been developed based on large re-use of a common implementation covering the majority of the required functions, which is referred to as mission control system infrastructure. The generation currently in operations has been successfully used for all categories of missions, including many commercial ones operated outside ESOC. It is however anticipated that its implementation is going to face obsolescence in the coming years, thus an ambitious Project is currently on-going aiming at the development and deployment of a completely new generation. This Project capitalizes as much as possible on the European initiative (referred to as EGS-CC) which is progressively developing and delivering a modern and advanced platform forming the basis for any type of monitoring and control applications for space systems. This paper is going to provide a technical overview of the two infrastructure generations, highlighting the main differences from a technical and usability standpoints. Lessons learned from previous and current developments will also be analyzed.

WEAPP03	Converting From NIS to Redhat Identity Management	network, controls, Linux, database	871
	T.S. McGuckin, R.J. Slominski JLab, Newport News, Virginia, USA
	Funding: This material is based upon work supported by the U.S. Department of Energy, Office of Science, Office of Nuclear Physics under contract DE-AC05-06OR23177. The Jefferson Lab (JLab) accelerator controls network has transitioned to a new authentication and directory service infrastructure. The new system uses the Red Hat Identity Manager (IdM) as a single integrated front-end to the Lightweight Directory Access Protocol (LDAP) and a replacement for NIS and a stand-alone Kerberos authentication service. This system allows for integration of authentication across Unix and Windows environments and across different JLab computing environments, including across firewalled networks. The decision making process, conversion steps, issues and solutions will be discussed.

WEAPP04	ICS Infrastructure Deployment Overview at ESS	network, controls, database, framework	875
	B. Bertrand, S. Armanet, J. Christensson, A. Curri, A. Harrisson, R. Mudingay ESS, Lund, Sweden
	The ICS Control Infrastructure group at the European Spallation Source (ESS) is responsible for deploying many different services. We treat Infrastructure as code to deploy everything in a repeatable, reproducible and reliable way. We use three main tools to achieve that: Ansible (an IT automation tool), AWX (a GUI for Ansible) and CSEntry (a custom in-house developed web application used as Configuration Management Database). CSEntry (Control System Entry) is used to register any device with an IP address (network switch, physical machines, virtual machines). It allows us to use it as a dynamic inventory for Ansible. DHCP and DNS are automatically updated as soon as a new host is registered in CSEntry. This is done by triggering a task that calls an Ansible playbook via AWX API. Virtual machines can be created directly from CSEntry with one click, again by calling another Ansible playbook via AWX API. This playbook uses proxmox (our virtualization platform) API for the VM creation. By using Ansible groups, different proxmox clusters can be managed from the same CSEntry web application. Those tools give us an easy and flexible solution to deploy software in a reproducible way.

	Funding: ELI-ALPS is supported by the European Union and cofinanced by the European Regional Development Fund (GOP-1.1.1-12/B-2012-000, GINOP-2.3.6-15-2015-00001) ELI-ALPS will be the first large-scale attosecond facility accessible to the international scientific community and its user groups. Control system development has three major directions: vacuum control systems, optical control systems, as well as the integrated control, monitoring and data acquisition systems. The development of the systems has asked for different levels of integration. In certain cases low-level devices are integrated (e.g. vacuum valves), while in other cases complete systems are integrated (e.g. the Tango interface of a laser system). This heterogeneous environment is managed through the elaboration of a common and general architecture. Most of the hardware elements are connected to PLCs (direct control level), which are responsible for the low-level operation of devices, including machine protection functions, and data transfer to the supervisory control level (CLIs, GUIs). Certain hardware elements are connected to the supervisory layer (cameras), as well as the Tango interface of the laser systems. This layer handles also data acquisition with a special focus on the metadata catalogue.

WEBPP02	Centralized System Management of IPMI Enabled Platforms Using EPICS	EPICS, monitoring, controls, database	887
	K. Vodopivec ORNL, Oak Ridge, Tennessee, USA
	Funding: This work was supported by the U.S. Department of Energy under contract DE-AC0500OR22725. Intelligent Platform Management Interface (IPMI) is a specification for computer hardware platform management and monitoring. The interface includes features for monitoring hardware sensors like fan speed and device temperature, inventory discovery, event propagation and logging. All IPMI functionality is accessible without the host operating system running. With its wide support across hardware vendors and the backing of a standardization committee, it is a compelling instrumentation for integration into a control system for large experimental physics projects. Integrating IPMI into EPICS provides the benefit of centralized monitoring, archiving and alarming integrated with the facility control system. A new project has been started to enable this capability by creating a native EPICS device driver built on the open-source FreeIPMI library for the remote host connection interface. The driver supports automatic system components discovery for creating EPICS database templates, detailed device information from Field Replaceable Unit interface, sensor monitoring with remote threshold management, geographical PV addressing in PICMG based platforms and PICMG front panel lights readout.

WEBPP03	The Laser Megajoule Facility: Front End’s Control System	controls, software, laser, operation	891
	J. Langot, C. Baret, P. Fourtillan, J.F. Gleyze, D. Hamon, D. Lebeaux, A. Perrin CEA, LE BARP cedex, France
	The Laser Megajoule (LMJ) is a 176-beam laser facility, located at the CEA CESTA Laboratory near Bordeaux (France). It is designed to deliver about 1.5 MJ of energy to targets, for high energy density physics experiments, including fusion experiments. Six 8-beams bundles are currently operational. The Front-End is the LMJ subsystem built to deliver the laser pulse which will be amplified into the bundles. It consists of 4 laser seeders, producing the laser pulses with the expected specificities and 88 Pre-Amplifier Modules (PAM). In this paper, we introduce the architecture of the Front-End’s control system which coordinate the operations of the laser seeders and the PAMs’s control systems. We will discuss the ability of the laser seeders and their control systems to inject the 88 PAMs almost independently. Then we will deal with the functions that enable the expected laser performances in terms of energy, spatial and temporal shapes. Finally, the technics used to validate and optimize the operation of the software involved in the Front-End’s equipment performance will be detailed.

WECPR02	Benefits and Drawbacks of Using Rust in an Existing C/C++ Codebase	EPICS, MMI, framework, target	928
	B.S. Martins FRIB, East Lansing, Michigan, USA
	Mozilla has recently released a new programming language, Rust, as a safer and more modern alternative to C++. This work explores the benefits (chiefly the features provided by Rust) and drawbacks (the difficulty in integrating with a C ABI) of using Rust in an existing codebase, the EPICS framework, as a replacement for C/C++ in some of EPICS’ modules.

Fangohr University of Southampton, Southampton, United Kingdom
	To achieve a tight integration of instrument control and (online) data analysis, the European XFEL decided in 2011 to develop Karabo, a custom control and data processing system. Karabo provides control via event-driven communication. Signal/slot and request/reply patterns are implemented via a central message broker. Data pipelines for e.g. scientific workflows or detector calibration are implemented as direct TCP/IP connections. The core entities of Karabo are self-describing devices written in C++ or Python. They represent hardware, orchestrate other devices, or provide system services like data logging and configuration storage. To operate Karabo, a Python command line interface and a generic GUI written in PyQt are provided. Control and data widgets compose Karabo scenes that are provided by devices or are manually customized and stored together with device configurations in a central database. Since 2016, Karabo is used to commission and operate the currently three photon beam lines and six scientific instruments at the European XFEL. This contribution summarizes the status of Karabo, highlights achievements and lessons learned, and gives an outlook for future directions. Heisen, B., et al.

WEDPL01	In-Place Technology Replacement of a 24x7 Operational Facility: Key Lessons Learned and Success Strategies From the NIF Control System Modernization	controls, software, operation, CORBA	950
	M. Fedorov, G.K. Brunton, C.M. Estes, B.T. Fishler, M.S. Flegel, A.P. Ludwigsen, M. Paul, S.L. Townsend LLNL, Livermore, California, USA
	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 largest laser system for Inertial Confinement Fusion (ICF) and High Energy Density (HED) experiments. Design of NIF control system started in the 1990s, incorporating established hardware and software technologies of that era. The architecture of the control system has stood the test of time, successfully scaling up to full 192 laser beam configuration in 2009, and then transitioning to 24x7 operations and sustaining 400 shots annually since 2016. The control system has grown with NIF to add new major capabilities, such as cryogenic layering, a petawatt-class laser, 3D neutron imaging and others. In parallel, with scaling up and efficiency optimizations, the software had to adapt to changes dictated by the fast-paced computer industry. Some of our originally chosen technologies have become obsolete and replaced by new programming languages, frameworks and paradigms. In this talk, we will discuss how the NIF control system has leveraged the strengths of its distributed, cross-platform architecture to successfully modernize "in-place" computing platforms and programming languages without impacting the demanding experiment schedule.

WEDPL04	Consolidation and Redesign of CERN Industrial Controls Frameworks	controls, framework, experiment, 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.

	G. Strangolino Elettra-Sincrotrone Trieste S.C.p.A., Basovizza, Italy
	Cumbia libraries offer the next generation core (C++) and graphical (Qt) software to write complete and lightweight applications that provide a unified user interface, regardless of the underlying engine (Tango, EPICS, WebSocket, …) With the new formula plugin, results can be manipulated and combined by JavaScript functions and displayed in the appropriate widget. Qt has a deep JavaScript integration that allows efficient introduction of program logic into the application. Using the Qt + QML technologies, apps can be designed for the desktop and mobile devices. Switching between the two targets is an immediate operation. A WebSocket based service* has been used to test Qt + QML mobile applications on portable devices. It makes it possible to connect to Tango and EPICS without their installation. A new tool called "la-cumparsita" lets non-programmers use the Qt designer to realize complete applications ready to communicate with the control system in use: Tango, EPICS or any other abstraction framework (e.g. WebSocket). These apps seamlessly integrate with the desktop. Most demanding users can integrate JavaScript functions and use them as data sources for the GUI elements. *The "canoned" service. It is part of the PWMA project (GPL3 LICENSE) and exposes a WebSocket interface.

WEDPR02	Benefits of Low Code Development Environments on Large Scale Control Systems	controls, software, MMI, PLC	976
	B. Lefort, V. Costa CERN, Meyrin, Switzerland
	The rapid evolution of science and of scientific projects usually implies high levels of mobility among researchers, engineers and applied scientists. In parallel, software development has been getting easier and easier as computing technology has evolved. One direct consequence of these two paradigms is a proliferation of small software that becomes vulnerable in many ways, when the person who develops and maintains it departs. Inspector is a low-code development platform to design control interfaces. It features a visual interface composer, a visual programming language and supports Python. More than 600 Inspector applications are used at CERN. We will explain how people with little experience of writing software can develop applications that they could not otherwise explicitly code for themselves. Finally, we will demonstrate how it offers the organization enhanced security and higher productivity, as well as relieving the load on IT for bug fixes and non-compliance.

	The application framework used in Fermilab’s Control System is proprietary and was written decades ago. Considered state-of-the-art at one time, it now lacks many features we expect from a modern interface and needs to be replaced. Our investigation of Web browsers and JavaScript revealed a powerful, rich, and state-of-the-art development environment. We discuss JavaScript frameworks, JavaScript language features, and packaging tools. We also discuss issues we need to resolve before we are confident this can become our primary application platform.

WEMPL004	Inception of a Learning Organization to Improve SOLEIL’s Operation	operation, software, database, controls	1001
	A. Buteau, G. Abeillé, X. Delétoille, J.-F. Lamarre, T. Marion, L.S. Nadolski SOLEIL, Gif-sur-Yvette, France
	High quality of service is SOLEIL is a key mission since 2007. Historically operation processes and information systems have been defined mostly on the fly by the different teams all along the synchrotron’s journey. Some major outcomes are a limited cross-teams collaboration and a slow learning organization. Consequently, we are currently implementing a holistic approach with common operational processes upon a shared information system. Our first process is "incident management"; an incident is an unplanned disruption or degradation of service. We have tackled incident management for IT* in 2015, then for the accelerators since January 2018. We are starting to extend it to beamlines since beginning 2019. As a follow-up, we will address the "problem management" process (a problem is the cause of one or more incidents) and the creation of a knowledge base for the operation. By implementing those processes, the culture of continuous improvement is slowly spreading, in particular by driving blameless incident and problem analysis. This paper will present the journey we have been through including our results, improvements and difficulties of implementing this new way of thinking. *ICALEPCS 2015: MOPGF150

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

WEMPL007	EPICS Controlled Wireless Sensors	controls, network, EPICS, software	1015
	M.T. Rolland Stony Brook University, Computer Science Department, Stony Brook, New York, USA K.J. Gofron BNL, Upton, New York, USA
	At the trade-off of power, wireless technologies are much more portable and convenient than their wired counterparts. This is especially true in the scientific sphere, where many environmental factors must be recorded at all times at as many locations as possible. Using these technologies, scientists can often reduce cost while maximizing the number of sensors without compromising sensor quality. To this end, we have developed EPICS controllers for both Bluetooth Low Energy (BLE) sensors and XBee ZigBee sensors. For BLE, we chose the Nordic Thingy:52 for its low cost, high battery life, and impressive range of sensors. The controller we developed combines EPICS base functions, the Bluetooth generic attribute data structure library, and multithreading techniques to enable real-time broadcast of the Thingy’s 20+ sensors’ live values. Because BLE is limited in range, we also developed a controller for the XBee sensor which, through the ZigBee mesh protocol, can expand its range through each node added into the network. With these controllers, NSLS-II scientists will have access to a whole new class of sensors which are both easier to deploy and cheaper than their wired predecessors.

WEMPR003	Exploring Embedded Systems’ Dedicated Cores for Real-Time Applications	controls, hardware, real-time, operation	1036
	P.H. Nallin, J.G.R.S. Franco, R.C. Ito, A.R.D. Rodrigues LNLS, Campinas, Brazil
	Developments and research in high technology leads to powerful and sophisticated machines which are highly important for many scientific fields. Considering real-time applications, however, these systems tend to become non-deterministic and users may find themselves inside a not completely controllable environment. Exploring open-hardware single board computers with a system-on-a-chip which usually runs an operational system on their main processor(s) and also have real-time units is a good alternative. These real-time units are designed as a microcontroller embedded on the chip where a firmware is loaded, runs concomitantly and exchanges data with the main system. As a result, it is possible to achieve performance increase, high temporal resolution and low latency and jitter, features that are widely desired for controls and critical data acquisition systems. This system architecture allows moving real-time data into high level servers, such as Redis (Remote Dictionary Server) and EPICS, easily. This paper introduces and shows uses of Beaglebone Black, an inexpensive single-board computer, its Programmable Real-Time Units (PRUs) and data sharing with Redis data structure.

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

WEMPR008	Web Extensible Display Manager 2	controls, framework, experiment, 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.

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

WEPHA014	EPICS Archiver Appliance - Installation and Use at BESSY/HZB	EPICS, controls, hardware, vacuum	1093
	T. Birke HZB, Berlin, Germany
	After 2 years of tests and development, the EPICS Archiver Appliance went into operation at HZB/BESSY in April 2018. After running for a year as an optional new archiver, the Archiver Appliance switched places with the old Channel Archiver and is now the central productive archiver in currently three installations (four at the time of this conference) at HZB. To provide a smooth transition from the Channel Archiver to the EPICS Archiver Appliance for end users as well as applications, some frontends like e.g. the ArchiveViewer and other applications needed some modifications to be fully usable. New retrieval frontends are also provided and will replace the ArchiveViewer in the future. In addition the versatile retrieval API rapidly improved the development of Python applications for analysis and optimization. Experiences with installation, configuration, maintenance and use of the EPICS Archiver Appliance will be shared in this paper.

WEPHA023	Co-Simulation of HDL Using Python and MATLAB Over Tcl TCP/IP Socket in Xilinx Vivado and Modelsim Tools	simulation, controls, MMI, FPGA	1127
	Ł. Butkowski, B. Dursun, C. Gümüş, M.K. Karakurt DESY, Hamburg, Germany
	This paper presents the solution, which helps in the simulation and verification of the implementation of the Digital Signal Processing (DSP) algorithms written in hardware description language (HDL). Many vendor tools such as Xilinx ISE/Vivado or Mentor Graphics ModelSim are using Tcl as an application programming interface. The main idea of the co-simulation is to use the Tcl TCP/IP socket, which is Tcl build in feature, as the interface to the simulation tool. Over this interface the simulation is driven by the external tool. The stimulus vectors as well as the model and verification are implemented in Python or MATLAB and the data with simulator is exchanged over dedicated protocol. The tool, which was called cosimtcp, was developed in Deutsches Elektronen-Synchrotron (DESY). The tool is a set of scripts that provide a set of functions. This tool has been successfully used to verify many DSP algorithms implemented in the FPGA chips of the Low Level Radio Frequency (LLRF) and synchronization systems of the European X-Ray Free Electron Laser (E-XFEL) accelerator. Cosimtcp is an open source available tool.

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

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.

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

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

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.

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

Meaningful gesturing is important for an intuitive human-machine communication. This paper deals with methods suitable for identifying different finger, hand and head movements using supervised machine learning algorithms. On the one hand it discusses an implementation based on the k-nearest neighbor classification algorithm (traditional machine learning approach). On the other hand it demonstrates the classification potential of a convolutional neural network (deep learning approach). Both methods are capable of distinguishing between fast and slow, short and long, up and down, or right and left linear as well as clockwise and counterclockwise circular movements. The details of the different methods with respect to recognition accuracy and performance will be presented.

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

LCLS-II is a new FEL which is under construction at SLAC National Accelerator Laboratory. Its superconducting electron linac is able to produce up to 1.2 MW of beam power. Beam Containment System (BCS) is employed to limit the beam power and prevent excessive radiation in case of electron beam loss or FEL breach. Fast and slow shut-off paths are designed for devices with different response requirements. The system is required to shut-off the beam within 200 µs for some of the fast sensors. Fast path is based on custom electronic designs, and slow path leverages industrial safety-rated PLC hardware. The system spans for 4 km of LCLS-II and combines inputs from about 150 sensors of different complexity. Architecture is based on multiple levels starting with summing sensor inputs locally and to converting them into permits for the shut-off devices. Each level is implemented redundantly. Automated test and manual tests at all levels are implemented in the system. System architecture, electronics design and cable plant challenges are presented below.

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

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

There are a variety of beam current transformers that are used at all accelerator facilities for current and bunch charge measurements. Transformer signals are traditionally measured using integrator electronics followed by a digitizer. However, integrator circuits have a limited bandwidth and are susceptible to noise. By directly digitizing the output of the transformer, the signal bandwidth is limited only by the transformer characteristics and the digitizing platform. Digital integration and filtering can then easily be applied to reduce noise resulting in an overall improvement of the beam parameter measurements. This paper describes a Python-based application that performs the filtering and integration of a current transformer pulse that has been directly digitized by an oscilloscope.

CERN, Geneva, Switzerland

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

CERN uses a central alarm system to monitor its complex technical infrastructure. The Technical Infrastructure (TI) operators must handle a large number of alarms coming from several thousand equipments spread around CERN. In order to focus on the most important events and improve the time required to solve the problem, it is necessary to provide extensive helpful information such as alarm states of linked systems, a geographical overview on a detailed map and clear instructions to the operators. In addition, it is useful to temporarily inhibit alarms coming from equipment during planned maintenance or interventions. The tool presents all necessary information in one place and adds simple and intuitive functionality to ease the operation with an enhanced interface.

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.

PyDM (Python Display Manager) is a Python and Qt-based framework for building user interfaces for control systems providing a no-code, drag-and-drop system to make simple screens, as well as a straightforward Python framework to build complex applications. PyDM developers and users can easily create complex applications using existing Python packages such as NumPy, SciPy, Scikit-learn and others. With high level interfaces for data plugins and external tools, PyDM can be extended with new widgets, integration with facility-specific tools (electronic log books, data logger viewers, et cetera) as well as new data sources (EPICS, Tango, ModBus, Web Services, etc) without the need to recompile or change the PyDM internal source.

The detection of beam loss events in accelerators is an important task for machine and personal protection, and for optimization of beam trajectory. An optical beam loss monitor (oBLM) being developed by the Cockcroft Institute at Daresbury Laboratory required integration with the rest of the controls and timing system of the site’s electron accelerator, CLARA (Compact Linear Accelerator for Research and Applications). [1] This paper presents the design and implementation of an inexpensive solution using a Domino Ring Sampling device from PSI. Signals from the oBLM are acquired and can be processed to resolve beam loss events to a resolution of 0.2 m.

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

Fieldbuses and Industrial Ethernet networks are extensively used for the control of fast-pulsed magnets at CERN. With the ongoing trend to develop increasingly more complex low-level intelligent controllers near to the actuators and sensors, the flexibility to integrate these within different control architectures grows in importance. In order to reduce development efforts and keep the fieldbus choice open, a multi-network field-bus technology has been selected for the network interfacing part of the controllers. Such an approach has been successfully implemented for several projects such as the development of high voltage capacitor chargers/dischargers, the surveillance of floating solid-state switch and the monitoring of a power triggering system that, today, are interfaced either to PROFIBUS-DP or PROFINET networks. The integration of various fieldbus interfaces within the controller and the required embedded software/gateware to manage to network communication are presented. The gain in flexibility, modularity and openness obtained through this approach is also reviewed.

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

A linear superconducting accelerator is being constructed in our institute. Its vacuum control system should be convenient and reliable. We intend to concentrate the control of each vacuum unit into a control box that implement the simple hard interlocking logic and the final action output of the vacuum device and the complete interlocking logic between the vacuum devices is realized in the PLC. Operators can perform local operation through the front panel of the control box or remotely control through the computer by switching the local/remote switch. In addition, the control flow of vacuum extraction and the protection flow when leakage occurs are also given in this paper.

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

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

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

Modern particle accelerator facilities generate large amounts of data and face increasing demands on their operational performance. As the demand on accelerator operations increases so does the need for automated tuning algorithms and control to maximize uptime with reduced operator intervention. Existing tools are insufficient to meet the broad demands on controls, visualization, and analysis. We are developing a cloud based toolbox featuring a generic virtual accelerator control room for the development of automated tuning algorithms and the analysis of large complex datasets. This framework utilizes tracking codes combined with with algorithms for machine drift, low-level control systems, and other complications to create realistic models of accelerators. These models are directly interfaced with advanced control toolboxes allowing for rapid prototyping of control algorithms. Additionally, our interface provides users with access to a wide range of Python-based data analytics libraries for the study and visualization of machine data. In this paper, we provide an overview of our interface and demonstrate its utility on a toy accelerator running on EPICS.

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.

CERN is a major electricity consumer. In 2018 it consumed 1.25 TWh, 1/3 the consumption of Geneva. Monitoring of this consumption is crucial for operational reasons but also for raising awareness of the users regarding energy utilization. This monitoring is done via a system, developed internally and is quite popular within the CERN community therefore to accommodate the increasing requirements, a migration is underway that utilizes the latest technologies for data modeling and processing. We present the architecture of the new energy monitoring system with an emphasis on the data modeling, versioning and the use of graphs to store and process the model of the electrical network for the energy calculations. The algorithms that are used are presented and a comparison with the existing system is performed in order to demonstrate the performance improvements and flexibility of the new approach. The system embraces the Service Oriented Architecture principles and we illustrate how these have been applied in its design. The different modules and future possibilities are also presented with an analysis of their strengths, weaknesses, and integration within the CERN infrastructure.

CEA, LE BARP cedex, France

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

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.

Improving User Experience in Complex Systems

ESS, Copenhagen, Denmark

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

APS Upgrade multi-bend achromat accelerator (MBA) uses state-of-the-art embedded controllers coupled to various technical subsystems. These controllers have the capability to collect large amounts of fast data for statistics, diagnostics, or fault recording. At times, continuous real-time acquisition of this data is preferred, which presents a number of challenges that must be considered early on in the design; such as network architecture, data management and storage, real-time processing, and impact on normal operations. The design goal is selectable acquisition of turn-by-turn BPM data, together with additional fast diagnostics data. In this paper we discuss engineering specifications and the design of the MBA Data Acquisition System (DAQ). This system will interface with several technical subsystems to provide time-correlated and synchronously sampled data acquisition for commissioning, troubleshooting, performance monitoring and fault detection. Since most of these subsystems will be new designs for the MBA, defining the functionality and interfaces to the DAQ early in the development will ensure the necessary components are included in a consistent and systematic way.

The CLARA experiment at the STFC, Daresbury laboratory has just completed its first successful exploitation period. The CLARA controls system is being rapidly deployed as CLARA enters its next development phase and our current infrastructure is becoming hard to maintain. Virtualization of the server infrastructure will allow the rapid deployment, recovery and testing of systems infrastructure. This talk will review our experience of migrating several key services and IOCs to a virtualized environment. KVM and LXD have been evaluated against our current system and Ansible has been used to automate many tasks that were normally done by hand. The Archiver Appliance is being exploited beyond its original deployment and is a critical component of several analysis tool-chains. Virtualization allows development, maintenance and deployment of the archiver without disrupting its users. Virtualization is also used to manage the CLARA Virtual Accelerator. The Virtual Accelerator can now run with many instances proving useful for scientists. Originally, it was limited to one instance per server.

Old and New Generation Control Systems at ESA

controls, operation, ECR, monitoring

859

M. Pecchioli
ESA/ESOC, Darmstadt, Germany

Traditionally Mission Control Systems for spacecraft operated at the European Space Operations Centre (ESOC) have been developed based on large re-use of a common implementation covering the majority of the required functions, which is referred to as mission control system infrastructure. The generation currently in operations has been successfully used for all categories of missions, including many commercial ones operated outside ESOC. It is however anticipated that its implementation is going to face obsolescence in the coming years, thus an ambitious Project is currently on-going aiming at the development and deployment of a completely new generation. This Project capitalizes as much as possible on the European initiative (referred to as EGS-CC) which is progressively developing and delivering a modern and advanced platform forming the basis for any type of monitoring and control applications for space systems. This paper is going to provide a technical overview of the two infrastructure generations, highlighting the main differences from a technical and usability standpoints. Lessons learned from previous and current developments will also be analyzed.

ESS, Lund, Sweden

The ICS Control Infrastructure group at the European Spallation Source (ESS) is responsible for deploying many different services. We treat Infrastructure as code to deploy everything in a repeatable, reproducible and reliable way. We use three main tools to achieve that: Ansible (an IT automation tool), AWX (a GUI for Ansible) and CSEntry (a custom in-house developed web application used as Configuration Management Database). CSEntry (Control System Entry) is used to register any device with an IP address (network switch, physical machines, virtual machines). It allows us to use it as a dynamic inventory for Ansible. DHCP and DNS are automatically updated as soon as a new host is registered in CSEntry. This is done by triggering a task that calls an Ansible playbook via AWX API. Virtual machines can be created directly from CSEntry with one click, again by calling another Ansible playbook via AWX API. This playbook uses proxmox (our virtualization platform) API for the VM creation. By using Ansible groups, different proxmox clusters can be managed from the same CSEntry web application. Those tools give us an easy and flexible solution to deploy software in a reproducible way.

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

Funding: This work was supported by the U.S. Department of Energy under contract DE-AC0500OR22725.
Intelligent Platform Management Interface (IPMI) is a specification for computer hardware platform management and monitoring. The interface includes features for monitoring hardware sensors like fan speed and device temperature, inventory discovery, event propagation and logging. All IPMI functionality is accessible without the host operating system running. With its wide support across hardware vendors and the backing of a standardization committee, it is a compelling instrumentation for integration into a control system for large experimental physics projects. Integrating IPMI into EPICS provides the benefit of centralized monitoring, archiving and alarming integrated with the facility control system. A new project has been started to enable this capability by creating a native EPICS device driver built on the open-source FreeIPMI library for the remote host connection interface. The driver supports automatic system components discovery for creating EPICS database templates, detailed device information from Field Replaceable Unit interface, sensor monitoring with remote threshold management, geographical PV addressing in PICMG based platforms and PICMG front panel lights readout.

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

To achieve a tight integration of instrument control and (online) data analysis, the European XFEL decided in 2011 to develop Karabo*, a custom control and data processing system. Karabo provides control via event-driven communication. Signal/slot and request/reply patterns are implemented via a central message broker. Data pipelines for e.g. scientific workflows or detector calibration are implemented as direct TCP/IP connections. The core entities of Karabo are self-describing devices written in C++ or Python. They represent hardware, orchestrate other devices, or provide system services like data logging and configuration storage. To operate Karabo, a Python command line interface and a generic GUI written in PyQt are provided. Control and data widgets compose Karabo scenes that are provided by devices or are manually customized and stored together with device configurations in a central database. Since 2016, Karabo is used to commission and operate the currently three photon beam lines and six scientific instruments at the European XFEL. This contribution summarizes the status of Karabo, highlights achievements and lessons learned, and gives an outlook for future directions.

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

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.

Cumbia libraries offer the next generation core (C++) and graphical (Qt) software to write complete and lightweight applications that provide a unified user interface, regardless of the underlying engine (Tango, EPICS, WebSocket, …) With the new formula plugin, results can be manipulated and combined by JavaScript functions and displayed in the appropriate widget. Qt has a deep JavaScript integration that allows efficient introduction of program logic into the application. Using the Qt + QML technologies, apps can be designed for the desktop and mobile devices. Switching between the two targets is an immediate operation. A WebSocket based service* has been used to test Qt + QML mobile applications on portable devices. It makes it possible to connect to Tango and EPICS without their installation. A new tool called "la-cumparsita" lets non-programmers use the Qt designer to realize complete applications ready to communicate with the control system in use: Tango, EPICS or any other abstraction framework (e.g. WebSocket). These apps seamlessly integrate with the desktop. Most demanding users can integrate JavaScript functions and use them as data sources for the GUI elements.
*The "canoned" service. It is part of the PWMA project (GPL3 LICENSE) and exposes a WebSocket interface.

Benefits of Low Code Development Environments on Large Scale Control Systems

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

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

Fermilab, Batavia, Illinois, USA

The application framework used in Fermilab’s Control System is proprietary and was written decades ago. Considered state-of-the-art at one time, it now lacks many features we expect from a modern interface and needs to be replaced. Our investigation of Web browsers and JavaScript revealed a powerful, rich, and state-of-the-art development environment. We discuss JavaScript frameworks, JavaScript language features, and packaging tools. We also discuss issues we need to resolve before we are confident this can become our primary application platform.

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

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

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

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

Developments and research in high technology leads to powerful and sophisticated machines which are highly important for many scientific fields. Considering real-time applications, however, these systems tend to become non-deterministic and users may find themselves inside a not completely controllable environment. Exploring open-hardware single board computers with a system-on-a-chip which usually runs an operational system on their main processor(s) and also have real-time units is a good alternative. These real-time units are designed as a microcontroller embedded on the chip where a firmware is loaded, runs concomitantly and exchanges data with the main system. As a result, it is possible to achieve performance increase, high temporal resolution and low latency and jitter, features that are widely desired for controls and critical data acquisition systems. This system architecture allows moving real-time data into high level servers, such as Redis (Remote Dictionary Server) and EPICS, easily. This paper introduces and shows uses of Beaglebone Black, an inexpensive single-board computer, its Programmable Real-Time Units (PRUs) and data sharing with Redis data structure.

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

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.

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

After 2 years of tests and development, the EPICS Archiver Appliance went into operation at HZB/BESSY in April 2018. After running for a year as an optional new archiver, the Archiver Appliance switched places with the old Channel Archiver and is now the central productive archiver in currently three installations (four at the time of this conference) at HZB. To provide a smooth transition from the Channel Archiver to the EPICS Archiver Appliance for end users as well as applications, some frontends like e.g. the ArchiveViewer and other applications needed some modifications to be fully usable. New retrieval frontends are also provided and will replace the ArchiveViewer in the future. In addition the versatile retrieval API rapidly improved the development of Python applications for analysis and optimization. Experiences with installation, configuration, maintenance and use of the EPICS Archiver Appliance will be shared in this paper.

This paper presents the solution, which helps in the simulation and verification of the implementation of the Digital Signal Processing (DSP) algorithms written in hardware description language (HDL). Many vendor tools such as Xilinx ISE/Vivado or Mentor Graphics ModelSim are using Tcl as an application programming interface. The main idea of the co-simulation is to use the Tcl TCP/IP socket, which is Tcl build in feature, as the interface to the simulation tool. Over this interface the simulation is driven by the external tool. The stimulus vectors as well as the model and verification are implemented in Python or MATLAB and the data with simulator is exchanged over dedicated protocol. The tool, which was called cosimtcp, was developed in Deutsches Elektronen-Synchrotron (DESY). The tool is a set of scripts that provide a set of functions. This tool has been successfully used to verify many DSP algorithms implemented in the FPGA chips of the Low Level Radio Frequency (LLRF) and synchronization systems of the European X-Ray Free Electron Laser (E-XFEL) accelerator. Cosimtcp is an open source available tool.

Successful integration of industrial equipment in the CERN accelerator complex relies mainly on 3 key components. The first part is the Controls Middleware (CMW). That provides a common communication infrastructure for the accelerator controls at CERN. The second part is timing. To orchestrate and align electronic and electrical equipment across the 27 km Large Hadron Collider (LHC) at sub nanosecond precision, an elaborate timing scheme is needed. Every component has to be configured and aligned within milliseconds and then trigger in perfect harmony with each other. The third and last bit is configuration management. The COTS devices have to be kept up to date, remotely managed and compatible with each other at all times. This is done through a combination of networked Pre eXecution Environments (PXE) mounting network accessible storage on the front ends, where operating systems and packages can be maintained across systems. In this article we demonstrate how COTS based National Instruments PXI and cRIO systems can be integrated in the CERN accelerator domain for measurement and monitoring systems.

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.

When completed, the European Spallation Source (ESS) will have around half a million of installed cables to power and control both the machine and end-stations instruments. To keep track of all these cables throughout the different phases of ESS, an application called Cable Database was developed at the Integrated Control System (ICS) Division. It provides a web-based graphical interface where authorized users may perform CRUD operations in cables, as well as batch imports (through well-defined EXCEL files) to substantially shortened the time needed to deal with massive amounts of cables at once. Besides cables, the Cable Database manages cable types, connectors, manufacturers and routing points, thus fully handling the information that surrounds cables. Additionally, it provides a programmatic interface through RESTful services that other ICS applications (e.g. CCDB) may consume to successfully perform their domain specific businesses. The present paper introduces the Cable Database and describes its features, architecture and technology stack, data concepts and interfaces. Finally, it enumerates development directions that could be pursued to further improve this application.

The European Spallation Source (ESS) is a neutron research facility based in Sweden that will be in operation in 2023. It is expected to have around 1500 IOCs controlling both the machine and end-station instruments. To manage the IOCs, an application called IOC Factory was developed at ESS. It provides a consistent and centralized approach on how IOCs are configured, generated, browsed and audited. The configuration allows users to select EPICS module versions of interest, and set EPICS environment variables and macros for IOCs. The generation automatically creates IOCs according to configurations. Browsing retrieves information on when, how and why IOCs were generated and by whom. Finally, auditing tracks changes of generated IOCs deployed locally. To achieve these functionalities, the IOC Factory relies on two other applications: the Controls Configuration Database (CCDB) and the ESS EPICS Environment (E3). The first stores information about IOCs, devices controlled by these, and required EPICS modules and snippets, while the second stores snippets needed to generate IOCs (st.cmd files). Combined, these applications enable ESS to successfully manage IOCs with minimum effort.

H. Kleines, F. Suxdorf
FZJ, Jülich, Germany

Main focus of slow control in neutron scattering is motion control for the movement of around 25 mechanical axes in a typical neutron instrument. The implementation of motion control functions in the JCNS neutron instruments at the FRM II research reactor in Garching, Germany, is based on Siemens S7 PLCs. A communication protocol called PMcomm which is optimized for motion control applications in neutron instruments has been developed at JCNS. PMcomm (PROFI motion communication) is based on PROFINET or PROFIBUS as the underlying transport protocol in order to facilitate the easy integration into the PLC world. It relies on the producer/consumer communication mechanism of PROFINET and PROFIBUS for the efficient direct access to often-used data like positions or status information. Coordinated movement of groups of axes is facilitated by a generic controller/axes model that abstracts from the specifics of the underlying motion control hardware. Simplicity was a major design goal of the protocol in order to allow an efficient and easy implementation on PLCs.

EPICS V3 provides simple data types accessible over the network through Channel Access identified by a flat process variable (PV) name. This flexibility is often regarded as a strength of EPICS, as the user can easily pick and choose the information they require. However, such data is almost always inter-related in some manner, pushing the burden of reconstructing that relationship to the end-user/client. ophyd represents hardware in Python as hierarchical classes, grouping together related signals from the underlying control system. ophyd devices make imposing this hierarchy simple, readable, and descriptive. This structure allows ophyd to provide a consistent interface across a wide-range of devices, which can then be used by higher-level software for any number of tasks: from command-line inspection, to scanning/data collection (bluesky), or even automatic GUI generation (typhon, adviewer). ophyd contains a number of pre-built devices for common hardware (and IOCs) as well as the tools to build custom devices.

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

Funding: This material is based upon work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DE-SC0000661, the State of Michigan, and Michigan State University.
The Beam Instrumentation and Measurements group at the Facility for Rare Isotope Beams is responsible for maintaining several EPICS IOC instances for beam diagnostics, of different IOC types, which end up generating tens of thousands of PVs. Given the heterogeneity of Diagnostics devices, the need to archive data for scientific and debugging purposes, and space limitations for archived data storage, there is a need for having per-PV (as opposed to per-Record) archiving rules in order to maximize utility and minimize storage footprint. This work will present our solution to the problem: "IOC Manager", a custom tool that leverages continuous integration, a relational database, and a custom EPICS module to allow users to specify regular-expression based rules for the archiver in a web interface.

The control system of the Elettra Sincrotrone Trieste infrastructure plants (cooling water, air conditioning, electricity, etc.) consists of several Siemens PLCs connected by an Ethernet network and a number of management stations running the Siemens Desigo software for high-level operation and monitoring, graphical display of the process variables, automatic alarm distribution and a wide range of different data analysis features. No external interface has been realized so far to connect Desigo to the Elettra and FERMI accelerator control systems based on Tango, making it difficult for the control room operators to monitor the conventional plant operation and parameters (temperature, humidity, water pressure, etc.), which are essential for the accelerator performance and reliability. This paper describes the development of a dedicated Desigo application to make selected process variables externally visible to a specific Tango device server, which then enables the use of all the tools provided by this software framework to implement graphical interfaces, alarms, archiving, etc. New proposals and developments to expand and improve the system are also discussed.

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.

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

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.

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

An extensive management functionality is one of the key advantages of the MicroTCA.4 standard. Monitoring and control of more than 350 MicroTCA crates and thousands of AMC and RTM modules installed at XFEL, FLASH, SINBAD and ANGUS experiments has been integrated into the DOOCS-based control system. A DOOCS middle layer server together with Java-based GUIs - JDDD and JDTool - developed at DESY, enable remote management and provide information about MicroTCA shelves and components. The integrated management includes inventory information, monitoring current consumption, temperatures, voltages and various types of the built-in sensors. The system event logs and collected histories of the sensors are used to investigate failures and issues.

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.
Conventional facility controls, such as those used for water and cooling systems, are often developed and operated independent of the accelerator control system using commercial SCADA systems. At the Spallation Neutron Source, these systems are fully integrated into the EPICS based machine control system to facilitate optimal machine performance. BACnet is the predominant communication protocol used in the building automation industry, thus inspiring SNS to develop a BACnet/IP software driver for EPICS to enable this integration. This paper describes how SNS uses the BACnet driver and standard EPICS tools to perform custom chiller sequencing to manage chiller system performance and meet accelerator requirements for high availability.

After about two years in operation the bunch-synchronized data acquisition as used with the accelerator control system at the European XFEL is being revisited and reevaluated. As we have now gained quite some experience with the current system design it was found to have shortfalls specifically with respect to the offered methods for data retrieval and management. In the context of modern data collection and management technologies readily in use by huge internet companies, new frameworks are being evaluated as a control-system independent replacement for data reduction, processing and online analysis. The main focus here is currently put on streaming technologies. Different approaches are being discussed in this paper and reviewed for feasibility and adaptability for control system architectures used at DESY’s accelerator facilities.

We post a new EPICS channel archiver system that is being developed at LANSCE of Los Alamos National Laboratory. Different from the legacy archiver system, this system is built on InfluxDB database and Plotly visualization toolkits. InfluxDB is an opensource time series database system and provides a SQL-like language for fast storage and retrieval of time series data. By replacing the old archiving engine and index file with InfluxDB, we have a more robust, compact and stable archiving server. On a client side, we introduce a new implementation combined with asynchronous programming and multithreaded programming. We also describe a web-based archiver configuration system that is associated with our current IRMIS system. To visualize the data stored, we use the JavaScript Plotly graphing library, another open source toolkit for time series data, to build frontend pages. In addition, we also develop a viewer application with more functionality including basic data statistics and simple arithmetic for channel values. Finally, we propose some ideas to integrate more statistical analysis into this system.

Phoebus is a Java/JavaFX framework for creating state-of-the-art, next-generation desktop applications for monitoring and controlling EPICS systems. The recent developments in Java and JavaFX have made it possible to reconsider the role of the Eclipse Rich Client Platform (RCP) in the development of client applications. Phoebus’s aim is to provide a simple to use and yet "rich-enough" application framework to develop modular JavaFX desktop applications for the most recent Java platform. Phoebus is an extensible framework for multiple control system protocols. It provides features for developing robust and scalable multi-threaded client applications. Key features include event rate decoupling, caching and queuing, and a common set of immutable data types to represent controls data from various protocols. The paper describes the framework as used to implement applications and service for monitoring EPICS PVs. The benefits highlighted will provide the EPICS community a new development perspective.

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

The CS-Studio alarm system was originally based on a relational database and the Apache ActiveMQ message service. The former was necessary to store configuration and state, while the latter communicated state updates and user actions. In a recent update, the combination of relational database and ActiveMQ have been replaced by Apache Kafka. We present how this simplified the implementation while at the same time improving performance.

IPFN - IST, Bobadela, Portugal

Continuous integration is widespread in software development, but a number of factors have thus far limited its use in PLC (Programmable Logic Controller) application development. A key requirement of continuous integration is that build and test stages must be automated. Automation of the build stage can be difficult for PLC developers, as building is typically performed with proprietary engineering tools. This has been solved by developing command line utilities which use the APIs of these tools. Another issue is that the program must be deployed to a real target (PLC) in order to test, something that is typically easier to do in other types of software development, where virtual environments may easily be used. This is solved by expanding the command line utilities to allow fully automated deployment of the PLC program. Finally, testing the PLC program presents its own challenges, as it is typically undesirable to alter the program in order to implement the tests natively in the PLC. This is avoided by using an industry standard protocol (OPC UA) to access PLC variables for testing purposes, allowing tests to be performed on an unaltered program.

In an environment of rapidly expanding and changing control systems, a solution geared towards the automation of application dependent Programmable Logic Controller (PLC) projects becomes an increasing need at the European X-Ray Free Electron Laser (EuXFEL). Through the standardization of components in the PLC Framework, it becomes feasible to develop tools in order to automate the generation of over 100 Beckhoff PLC Projects. The focus will be on the PLC Management System (PLCMS) tool developed to achieve this. Provided with an electrical diagram markup (EPLAN XML export), the PLCMS queries the database model populated from the PLC Framework. It captures integration parameters and compatible EtherCAT fieldbus hardware. Additionally, inter-device communication and interlocking processes are integrated into the PLC from a defined user template by the PLCMS. The solution provides a flexible and scalable means for automatic and expedited deployment for the PLC control systems. The PLCMS can be further enhanced by interfacing into the Supervisory Control and Data Acquisition (SCADA) system for complete asset management of both PLC software and connected hardware across the facility.

FPGA based fast electronics to acquire and pre-process signals of detectors and diagnostics and PLC based hardware and software for motion, vacuum and other control and monitoring applications are key elements of the European X-Ray Free Electron Laser. In order to bring the newly developed scientific user facility up and running, the underlying electrical and electronic components require a diverse array of tools and processes to be developed in order to meet the continually adapting requirements and make use of technological advances. Many challenges were faced, including high availability and up-time, adaptability to a dynamic environment, rapid lead-time for integration of complex components, numerous instrumentation installations and commissioning, high time resolution and subsequently, high demands on data and sampling rates, synchronization and real-time processing. In this contribution we will provide an overview of the selected technologies, developed concepts and solutions along with generically designed frameworks and tools, which aim to provide a high degree of standardization on the control systems and even automatic generation from requirements to final install.

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