MOPHA072	Automation in NSRC SOLARIS With Python and Tango Controls	controls, TANGO, MMI, real-time	382
	W.T. Kitka, M.K. Falowski, A.M. Marendziak, N. Olszowska, M. Zając NSRC SOLARIS, Kraków, Poland
	NSRC SOLARIS is a 1.5 GeV third generation light source constructed at Jagiellonian University in Kraków, Poland. The machine was commissioned in April 2016 and operates in decay mode. Two beamlines PEEM/XAS and UARPES were commissioned in 2018 and they have opened for conducting research in fall 2018. Two more beamlines (PHELIX and XMCD) are installed now and will be commissioned soon. Due to small size of the team and many concurrent tasks, automation is very important. Automating many tasks in a quick and effective way is possible thanks to the control system based on TANGO Controls and Python programming language. With facadevice library the necessary values can be easily calculated in real-time. Beam position correction with PID controller at PEEM/XAS and UARPES beamlines, alarm handling in SOLARIS Heating Unit Controller and real-time calculation of various vacuum parameters are shown as examples.

	The Vacuum Controls Configurator (vacCC) is an application developed at CERN for the management of large-scale vacuum control systems. The application was developed to facilitate the management of the configuration of the vacuum control system at CERN, the largest vacuum system in operation in the world, with over 15,000 vacuum devices spread over 128 km of vacuum chambers. It allows non-experts in software to easily integrate or modify vacuum devices within the control system via a web browser. It automatically generates configuration data that enables the communication between vacuum devices and the supervision system, the generation of SCADA synoptics, long and short term archiving, and the publishing of vacuum data to external systems. VacCC is a web application built for the cloud, dockerized, and based on a microservice architecture. In this paper, we unveil the application’s main aspects concerning its architecture, data flow, data validation, and generation of configuration for SCADA/PLC.

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.

WECPL03	Implementation of the Motion Control System for LCLS-II Undulators	undulator, controls, EPICS, hardware	915
	M.A. Montironi, C.J. Andrews, H. Bassan, K.R. Lauer, Yu.I. Levashov, H.-D. Nuhn, Z.R. Wolf SLAC, Menlo Park, California, USA Ž. Oven Cosylab, Ljubljana, Slovenia
	As part of the LCLS upgrade called LCLS-II, two new undulator lines were introduced: a soft X-Ray line (SXR) and a hard H-Ray line (HXR). Serving distinct purposes, the two undulator lines employ different undulator designs. The SXR line is composed of 21 vertical gap, horizontally polarized undulators while the HXR line is composed of 32 undulator segments designed to operate on the horizontal axis and to produce a vertically polarized beam. The HXR undulators will replace the LCLS ones and thus the control system was designed with the main goal of maximizing the re-utilization of existing hardware and software. For this purpose, the motion control system based on RTEMS running on VME with Animatics SmartMotors was developed as an upgrade of the LCLS design and the cam-based undulator girder positioning system has been reused. The all new SXR undulators employ a new control system design based on Aerotech motion controllers and EPICS soft IOCs (input-output controllers). This paper describes how the most challenging motion control requirements were implemented focusing on motion synchronization, K-value to gap transformation, cams kinematics and calibration, and user interaction.

WEPHA014	EPICS Archiver Appliance - Installation and Use at BESSY/HZB	EPICS, controls, hardware, interface	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.

WEPHA017	Integration of Wireless Mobile Equipment in Supervisory Application	controls, PLC, database, MMI	1102
	S. Blanchard, R. Ferreira, P. Gomes, G. Pigny, A.P. Rocha CERN, Geneva, Switzerland
	Pumping group stations and bake-out control cabinets are temporarily installed close to vacuum systems in CERN accelerator tunnels, during their commissioning. The quality of the beam vacuum during operation depends greatly on the quality of the commissioning. Therefore, the integration of mobile equipment in the vacuum supervisory application is primordial. When connected to the control system, the mobile stations appear automatically integrated in the synoptic. They are granted with the same level of remote control, diagnostics and data logging as fixed equipment. The wireless connection and the communication protocol with the supervisory application offer a flexible and reliable solution with high level of integrity.

WEPHA052	Engineering Support Activities at ELI-ALPS Through a Systems Engineering Perspective	controls, laser, operation, software	1219
	L.J. Fülöp, F. Horvath, I. Kiss, A. Makai, L. Schrettner ELI-ALPS, Szeged, Hungary
	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. The core business of ELI-ALPS is to generate attosecond pulses and provide these to the prospective users. In order to reach this ultimate goal, one key support area, the engineering development of complex systems as well as the engineering custom design service, has been systematically elaborated based on the standards, recent results, trends and best practices of systems engineering. It covers the boundaries towards all related support areas, from building operation and maintenance, to the custom manufacturing provided by the workshops, with the intention to make the model as well as the daily work as comprehensive and consistent as possible. Different tools have been evaluated and applied through the years, however, a key lessons learned is that some of the most important tools are teamwork, personal communication and constructive conflicts.

WEPHA068	A Control System Using EtherCAT Technology for The Next-Generation Accelerator	controls, PLC, gun, LLRF	1258
	M. Ishii, M.T. Takeuchi JASRI/SPring-8, Hyogo-ken, Japan T. Fukui RIKEN SPring-8 Center, Innovative Light Sources Division, Hyogo, Japan C. Kondo JASRI, Hyogo, Japan
	The construction of a new 3 GeV Light Source is in progress. The 3 GeV Light Source will be designed a compact and stable Linac based on the C-band accelerator developed by SACLA. Furthermore, we have an upgrade project of SPring-8 that we call SPring-8-II. We adopted EtherCAT technology as a network fieldbus for the next-generation control system. Currently, as the control systems using EtherCAT, a low-level RF system and a new standard in-vacuum undulator system are running at the SPring-8 storage ring. Additionally, it is necessary to upgrade a high-power RF (HPRF) system at SACLA and a magnet power supply system. The current HPRF system consists of a VME and four PLCs. These PLCs are connected by an optical FA-Link that had been discontinued. Therefore, we will construct a new HPRF system that is replaced a VME with MTCA.4 and is used EtherCAT as a fieldbus. A fieldbus of a magnet power supply system will be replaced an old optical link with EtherCAT. The new systems will be verified into a prototype accelerator for the 3 GeV Light Source in SPring-8 site. The control systems using EtherCAT will be installed into the 3 GeV Light Source and SPring-8-II.

	The Taiwan photon source (TPS) is a 3 GeV photon source. For the vacuum system NI CompactRIO controllers with embedded real-time processors and programmable FPGAs were selected to design the inter-lock system to maintain ultra-high vacuum conditions and protect vacuum devices. The vacuum pressure protection function and component protection logics worked well during the past years of operation. Be-sides, basic function and other applications such as TCP/IP Modbus communication and real time message APIs were developed. The architecture of the vacuum control system is presented in this paper.

WESH2001	CS-Studio Alarm System Based on Kafka	GUI, interface, controls, toolkit	1504
	K.-U. Kasemir ORNL, Oak Ridge, Tennessee, USA
	Funding: This material is based upon work supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under contract number DE-AC05-00OR22725. The 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.

THCPL05	Signal Analysis for Automated Diagnostic Applied to LHC Cryogenics	cryogenics, software, Windows, controls	1601
	K.O.E. Martensson, B. Bradu, G. Ferlin CERN, Geneva, Switzerland
	The operation of the LHC at CERN is highly dependent on its associated infrastructure to operate properly, such as its cryogenic system where many conditions must be fulfilled for superconducting magnets and RF cavities. In 2018, the LHC cryogenic system caused 172 hours of accelerator downtime (out of 5760 running hours). Since the cryogenics recovery acts as a time amplifier, it is important to identify not optimized processes and malfunctioning systems at an early stage to anticipate losses of availability. The LHC cryogenic control systems embeds about 60,000 I/O whereof more than 20,000 analog signals which have to be monitored by operators. It is therefore crucial to select only the relevant and necessary information to be presented. This paper presents a signal analysis system created to automatically generate adequate daily reports on potential problems in the LHC cryogenic system which are not covered by conventional alarms, and examples of real issues that have been found and treated during the 2018 physics run. The analysis system, which is written in Python, is generic and can be applied to many different systems.

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.

As part of the LCLS upgrade called LCLS-II, two new undulator lines were introduced: a soft X-Ray line (SXR) and a hard H-Ray line (HXR). Serving distinct purposes, the two undulator lines employ different undulator designs. The SXR line is composed of 21 vertical gap, horizontally polarized undulators while the HXR line is composed of 32 undulator segments designed to operate on the horizontal axis and to produce a vertically polarized beam. The HXR undulators will replace the LCLS ones and thus the control system was designed with the main goal of maximizing the re-utilization of existing hardware and software. For this purpose, the motion control system based on RTEMS running on VME with Animatics SmartMotors was developed as an upgrade of the LCLS design and the cam-based undulator girder positioning system has been reused. The all new SXR undulators employ a new control system design based on Aerotech motion controllers and EPICS soft IOCs (input-output controllers). This paper describes how the most challenging motion control requirements were implemented focusing on motion synchronization, K-value to gap transformation, cams kinematics and calibration, and user interaction.

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.

Pumping group stations and bake-out control cabinets are temporarily installed close to vacuum systems in CERN accelerator tunnels, during their commissioning. The quality of the beam vacuum during operation depends greatly on the quality of the commissioning. Therefore, the integration of mobile equipment in the vacuum supervisory application is primordial. When connected to the control system, the mobile stations appear automatically integrated in the synoptic. They are granted with the same level of remote control, diagnostics and data logging as fixed equipment. The wireless connection and the communication protocol with the supervisory application offer a flexible and reliable solution with high level of integrity.

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

The construction of a new 3 GeV Light Source is in progress. The 3 GeV Light Source will be designed a compact and stable Linac based on the C-band accelerator developed by SACLA. Furthermore, we have an upgrade project of SPring-8 that we call SPring-8-II. We adopted EtherCAT technology as a network fieldbus for the next-generation control system. Currently, as the control systems using EtherCAT, a low-level RF system and a new standard in-vacuum undulator system are running at the SPring-8 storage ring. Additionally, it is necessary to upgrade a high-power RF (HPRF) system at SACLA and a magnet power supply system. The current HPRF system consists of a VME and four PLCs. These PLCs are connected by an optical FA-Link that had been discontinued. Therefore, we will construct a new HPRF system that is replaced a VME with MTCA.4 and is used EtherCAT as a fieldbus. A fieldbus of a magnet power supply system will be replaced an old optical link with EtherCAT. The new systems will be verified into a prototype accelerator for the 3 GeV Light Source in SPring-8 site. The control systems using EtherCAT will be installed into the 3 GeV Light Source and SPring-8-II.

The Taiwan photon source (TPS) is a 3 GeV photon source. For the vacuum system NI CompactRIO controllers with embedded real-time processors and programmable FPGAs were selected to design the inter-lock system to maintain ultra-high vacuum conditions and protect vacuum devices. The vacuum pressure protection function and component protection logics worked well during the past years of operation. Be-sides, basic function and other applications such as TCP/IP Modbus communication and real time message APIs were developed. The architecture of the vacuum control system is presented in this paper.

Funding: This material is based upon work supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under contract number DE-AC05-00OR22725.
The 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.

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