WEO13	Strategy for Modernizing a 40-Year-Old Accelerator Control System	6
	B.F. Harrison Fermilab, Batavia, Illinois, USA
	Funding: Fermi Research Alliance Modernizing the Fermilab accelerator control system is essential to future operations of the laboratory’s accelerator complex. The existing control system has evolved over four decades and uses hardware that is no longer available and software that uses obsolete frameworks. The Accelerator Controls Operations Research Network (ACORN) Project will modernize the control system and replace end-of-life power supplies to enable future accelerator complex operations with megawatt particle beams. The project team is evaluating three design concepts, and the future deployment of artificial intelligence capabilities for accelerator operations is an important consideration. An overview of the ACORN Project will be presented, including R&D used for evaluating the conceptual designs in the context of requirements for future accelerator operations.

WEO21	Status of EPICS Based Control System for the Cyclotrons in VECC, Kolkata
	A. Roy, N. Chaddha, S. Sahoo VECC, Kolkata, India
	At present two cyclotrons are operational in Variable Energy Cyclotron Centre (VECC), namely K130 Room Temperature Cyclotron (RTC) and K500 Superconducting Cyclotron (SCC). Around 2008, the open source distributed control system framework, EPICS was adopted for the development of RTC control system in VECC after its modernization. The journey was started with EPICS Base 3.14.8, asynDriver R4-4 and MEDM. Initially, the control system for precision magnet power supplies and vacuum system of RTC were implemented using EPICS. Over time, other systems like beam diagnostics, ion source gas flow system, beam line vacuum system of RTC were integrated with EPICS control system. There are also a number of unique EPICS based developments took place in VECC. The control system of SCC is also upgraded with EPICS over time. Recently some of the cyclotron model and analysis codes are integrated with SCC control system. A MySQL based machine operational database is also developed for storing operational data. The Control System Studio (CSS) is now taken up for developing the operator interface. The evolution of EPICS based control system in VECC over time is discussed in this paper.

	Japan Proton Accelerator Research Complex (J-PARC) timing system has been in operation since 2006. Over the past 16 years, there were trigger-failure events, and some of which seriously affected the operation of J-PARC ac-celerator, especially at Main Ring. To troubleshoot the source of such events more quickly, we decided to devel-op a timing read-back system to read back distributed timing signals at the device side. A PLC-type triggered scaler module was developed as a key of the system. It can count number of pulses in an accelerator cycle and store the counts in a momentary array. Using the module, customized read-back applications for various timing-related signals have been developed: (a) read-back a 25-Hz trigger clock, (b) read-back a pulsed bending magnet trig-ger, (c) read-back a magnet power-supply trigger. These applications were implemented successfully in J-PARC Main Ring, and demonstrated as countermeasure against past trigger-failure events. More details will be given in the paper.

THO11	Building Control System Remotely	15
	M. Lukaszewski, K. Klys E9, London, United Kingdom
	Funding: European Regional Development Fund and the state budget of the Czech Republic project HiLASE CoE (CZ.02.1.01/0.0/0.0/15₀06/0000674); Horizon 2020 Framework Programme (H2020) (739573). Building a control system for a scientific facility is a complex process that requires a lot of time coordination and the cooperation of hundreds of people. The latest of our control system for 10 J 100 Hz laser system happened to be built when access to the lab was much more difficult, due to the pandemic that made travel much more complex, and local restrictions at one point prevented large number of people from being in the lab at the same time. This paper shows how, despite the demanding working conditions, we built the control system for the 10 J 100 Hz laser. The control system was designed in collaboration with CLF (STFC, UK) and HiLASE (Institute of Physics, ASCR). The whole process of building the laser control system was divided into stages and we had to rely on remote working. This article discusses how we adapted each stage to work remotely, what tools we used, how we minimised the risks, and what we would have done differently if we had started from scratch.

	J. Varlec, Ž. Oven, J. Varlec COSYLAB, Control System Laboratory, Ljubljana, Slovenia
	With increasing popularity of Beckhoff devices in scientific projects, there is an increasing need for their devices to be integrated into EPICS control systems. Projects often want to use Beckhoff PLCs for applications that have to handle a large amount of signals with fast cycle times. So, how can we connect Beckhoff devices to EPICS control systems without sacrificing performance? Beckhoff offers multiple possibilities when it comes to interfacing with their PLCs or industrial PCs, such as modbus, OPC UA, or ADS protocols. While all of these could be used for the usual use cases, we believe that for more data intensive applications, ADS works best. For this reason, Cosylab developed an EPICS device support module that implements advanced ADS features, such as ADS sum commands, which provide fast read/write capabilities to your IOCs.

	For the future Facility for Antiproton and Ion Research (FAIR), which is currently under construction, a new Control System is being developed and already used at major parts of the GSI facility. The central component for Settings Management within the FAIR Control System is based on CERN’s framework "LHC Software Architecture" (LSA) and enhanced by FAIR specific features. One of the most complex features is the control mechanism of storage ring operations, the so-called Storage Ring Mode. This operation mode allows to manipulate device settings while the beam is circulating in the ring. There are four different types of possible changes in the Storage Ring Mode: skipping, repetition, breakpoint and manipulation. The Storage Ring Mode was developed in late 2019 and first used with beam in 2020 at the existing heavy ion Storage Ring ESR at GSI. This contribution illustrates in detail how the Storage Ring Mode is implemented within LSA and other subsystems. It also shows how it is operated using the Expert Storage Ring Mode application.

THP04	EPICS Tango Bridge	57
	T.M. Madej, P.P. Goryl, M. Nabywaniec, Ł. Żytniak S2Innovation, Kraków, Poland
	EPICS (Experimental Physics and Industrial Control System) and Tango Controls are the two most popular control systems for scientific facilities. They both have advantages and disadvantages. Sometimes there is existing software driver supporting integration only with EPICS or Tango. EPICS Tango Bridge is the perfect solution for accessing Tango devices using EPICS Channel Access protocol. Using our bridge, the cost of integration is significantly lower than providing dedicated integration of specific hardware in EPICS. The bridge provides high reliability and robustness. Test cases created during the development process verify their limitations like the response time of reading one attribute in the bridge with a different number of Process Variables (PVs) or parallel access for multiple EPICS clients and many others.

THP05	Integration of Quench Detection Solution into FAIR’s FESA Control System	59
	M. Marn, A. Debenjak COSYLAB, Control System Laboratory, Ljubljana, Slovenia M. Dziewiecki GSI, Darmstadt, Germany
	Facility for Antiproton and Ion Research (FAIR) is going to make wide use of superconducting magnets for its components: the SIS100 synchrotron, the Superconducting Fragment Separator (SFRS) and Atomic, Plasma Physics and Applications (APPA) experiments. For all these magnets, uniform quench detection (QuD) electronics have been developed to protect them in case of uncontrolled loss of superconductivity. The QuD system will contain ca. 1500 electronic units, each having an Ethernet interface for controls, monitoring, data acquisition, and time synchronization. The units will be grouped into sub-networks of ca. 100 units and interfaced via dedicated control computers to the accelerator network. The interfacing software used to expose QuD functions to the FAIR controls framework is implemented as a Front-End Software Architecture (FESA) class. The software provides a solution for the constant collection of the data and monitoring of the system, storing the complete snapshot in the case a quench event is detected, and prompt notification of a quench to other components of the FAIR facility. The software is developed with special attention to robustness and reliability.

THP07	A Modern C++ Multiprocessing DOOCS Client Library Implementation	62
	S. Meykopff DESY, Hamburg, Germany
	At the DESY site in Hamburg/Germany the linear accelerators FLASH and European XFEL are successful operated by the control system DOOCS. DOOCS based on the client’server model and communicates with the matured SUN-RPC. The servers are build with a framework which consists of several C++ libraries. The clients use a DOOCS client library implementation in C++ or Java. In the past years the public interface (API) of the C++ client library was refined. But modern C++ features like futures are not provided in the API. Massive multi-processing, parallel communication, and optimized names resolution could improve the overall communication latency. The usage of the standard C++ library, the limit of external dependencies to SUN-RPC and OpenLDAP, and the reduction of the code size, may increase the maintainability of the code. This contribution presents an experimental new client C++ library which achieves these goals.

THP12	PLC Operated Plug and Play Vacuum Gauge Functionality at the Argonne Tandem Linear Accelerating System	69
	K.J. Bunnell, C. Dickerson, B.G. Nardi, D.J. Novak, D. Stanton ANL, Lemont, Illinois, USA
	The ATLAS (Argonne Tandem Linear Accelerating System) accelerator at Argonne National Laboratory is upgrading the vacuum control system from hardware-based, embedded controllers to modern flexible PLC- based controllers. This PLC system includes additional fail safes and a new remote operation feature. As part of this upgrade, a need for easy vacuum equipment replacement became apparent, specifically the vacuum gauges which are interfaced using serial communications. We developed an automated process to initialize and restore the configuration for replaced gauges. This simplifies the process and eliminates the need for a system expert for these tasks. This work was supported by the U.S. Department of Energy, Office of Nuclear Physics, under Contract No. DE-AC02-06CH11357.

EPICS (Experimental Physics and Industrial Control System) and Tango Controls are the two most popular control systems for scientific facilities. They both have advantages and disadvantages. Sometimes there is existing software driver supporting integration only with EPICS or Tango. EPICS Tango Bridge is the perfect solution for accessing Tango devices using EPICS Channel Access protocol. Using our bridge, the cost of integration is significantly lower than providing dedicated integration of specific hardware in EPICS. The bridge provides high reliability and robustness. Test cases created during the development process verify their limitations like the response time of reading one attribute in the bridge with a different number of Process Variables (PVs) or parallel access for multiple EPICS clients and many others.

Facility for Antiproton and Ion Research (FAIR) is going to make wide use of superconducting magnets for its components: the SIS100 synchrotron, the Superconducting Fragment Separator (SFRS) and Atomic, Plasma Physics and Applications (APPA) experiments. For all these magnets, uniform quench detection (QuD) electronics have been developed to protect them in case of uncontrolled loss of superconductivity. The QuD system will contain ca. 1500 electronic units, each having an Ethernet interface for controls, monitoring, data acquisition, and time synchronization. The units will be grouped into sub-networks of ca. 100 units and interfaced via dedicated control computers to the accelerator network. The interfacing software used to expose QuD functions to the FAIR controls framework is implemented as a Front-End Software Architecture (FESA) class. The software provides a solution for the constant collection of the data and monitoring of the system, storing the complete snapshot in the case a quench event is detected, and prompt notification of a quench to other components of the FAIR facility. The software is developed with special attention to robustness and reliability.

A Modern C++ Multiprocessing DOOCS Client Library Implementation

DESY, Hamburg, Germany

At the DESY site in Hamburg/Germany the linear accelerators FLASH and European XFEL are successful operated by the control system DOOCS. DOOCS based on the client’server model and communicates with the matured SUN-RPC. The servers are build with a framework which consists of several C++ libraries. The clients use a DOOCS client library implementation in C++ or Java. In the past years the public interface (API) of the C++ client library was refined. But modern C++ features like futures are not provided in the API. Massive multi-processing, parallel communication, and optimized names resolution could improve the overall communication latency. The usage of the standard C++ library, the limit of external dependencies to SUN-RPC and OpenLDAP, and the reduction of the code size, may increase the maintainability of the code. This contribution presents an experimental new client C++ library which achieves these goals.

The ATLAS (Argonne Tandem Linear Accelerating System) accelerator at Argonne National Laboratory is upgrading the vacuum control system from hardware-based, embedded controllers to modern flexible PLC- based controllers. This PLC system includes additional fail safes and a new remote operation feature. As part of this upgrade, a need for easy vacuum equipment replacement became apparent, specifically the vacuum gauges which are interfaced using serial communications. We developed an automated process to initialize and restore the configuration for replaced gauges. This simplifies the process and eliminates the need for a system expert for these tasks.
