WEC1	The Do’s and Don’ts in Process Controls - Lessons Learned Over 35 Years	controls, PLC, cryogenics, hardware	1
	M.R. Clausen, T. Boeckmann, J. Hatje, O. Korth, M. Möller, J. Penning, H.R. Rickens, B. Schoeneburg DESY, Hamburg, Germany
	Designing, implementing and maintaining process control systems for cryogenic plants requires different viewpoints compared with those in machine controls. 24/7 operations for more than a year is a basic requirement. Hardware and software must be designed to fulfill this requirement. Many projects are carried out with industrial partners. Companies specify the process control logic which gets implemented by the local DESY team. Responsibilities, time tables and milestones must be clearly defined in such a case. Several cryogenic installations have been equipped with state of the art process control systems for cryogenic controls. Where the last one being the European XFEL. In the course of time commercial and open source systems were implemented and maintained. Control loops were basically always implemented in front end controllers running the real-time operating system VxWorks and EPICS as the control system toolkit. The approach to use PLCs will be discussed as an alternative approach. Large installations like the European XFEL require good project planning. Our success story will finalize our look back and initiate our look forward.

	The high-gain free electron lasers have given scientists hopes for new scientific discoveries in many frontier research areas. The Shanghai HIgh repetition rate XFEL aNd Extreme light facility (SHINE) was proposed by the central government of P.R. China on April 2017, which is a quasi-continuous wave hard X-ray free electron laser facility. The control system is responsible for the facility-wide device control, data acquisition, machine protection, high level database or application, as well as network and computing platform. It will be mainly based on EPICS to reach the balance between the high performance and costs of maintenance. The latest technology will be adopted for the high repetition rate data acquisition and feedback system. The details of the control system design will be reported in this paper.

WEP07	Innovative Graphical User Interfaces Development: Give the Power Back to Users	GUI, interface, controls, radiation	44
	G. Segura, A. Ledeul, A. Savulescu, B. Styczen, D. Vazquez Rivera CERN, Meyrin, Switzerland
	GUI for supervision, control and data acquisition systems are usually oriented to specialist users. In big organizations like CERN, where different teams play the roles of operators, scientists and instrumentation specialists, providing a unique or static user interface usually results in a situation of dissatisfaction of everyone. On the other hand, providing distinct user interfaces for each type of user increases the development and maintenance effort and makes software evolution heavier. The approach taken for the design and development of GUIs for radiation and environment protection at CERN addressed this issue by integrating user interface changes as an embedded software functionality. Key users were provided with a tool to build, deploy and maintain their own tailor-made user interfaces, in a graphical way and without the necessity of learning any kind of programming or scripting languages. Other benefits observed from this solution include reduction of the resources spent on the support and maintenance and increase of the frequency of GUIs updates, executed without compromising the underlying control system. This paper describe the innovative design that was implemented.

WEP08	A Universal System Based on WebSocket and JSON for the Employment of LabVIEW External Drivers	LabView, controls, power-supply, network	47
	A. Stecchi, C. Bisegni, P. Ciuffetti, A. D’Uffizi, G. Di Pirro, F. Galletti, A. Michelotti INFN/LNF, Frascati, Italy
	One of the heaviest workloads when installing a Control System on a plant is the development of a large number of device drivers. This is even more true in the case of scientific facilities for which you typically deal with many custom devices and legacy code. In these cases, it is useful to consider the Rapid Application Development (RAD) approach that consists in lessen the planning phase and give more emphasis on an adaptive process, so that software prototypes can be successfully used in addition to or in place of design specifications. LabVIEW* is a typical RAD-oriented development tool and is widely used in technical laboratories where many stand-alone programs are developed to manage devices under construction or evaluation. An original system that allows software clients to use external LabVIEW drivers is presented. This system, originally created for the !CHAOS Control System*, is entirely written in LabVIEW and is based on JSON messages -transmitted on a WebSocket communication- driving LabVIEW VIs through dynamic calls. This system is completely decoupled from the client and is therefore suitable for any Control System. LabVIEW: http://www.ni.com ** L. Catani et al, Phys. Rev. ST Accel. Beams 15, 112804 (2012).

	P. Chevtsov, D. Anicic, V.R. Arsov PSI, Villigen PSI, Switzerland M. Dach Dach Consulting GmbH, Brugg, Switzerland
	The main driving part of the X-ray free electron laser facility (SwissFEL) at the Paul Scherrer Institute (PSI) is a compact electron linear accelerator (linac). The machine is highly optimized to generate a superior FEL radiation with the lowest suitable electron beam energy. In order to meet extremely stringent SwissFEL requirements for electron beam quality and stability, a variety of beam diagnostics tools were developed and implemented at the PSI. All these tools are integrated into the SwissFEL control system. The paper describes basic control elements of the electron beam diagnostics tools and their operational performance.

	Funding: The authors would like to thank the Swiss National Science Foundation for the financial support. The Electromagnetic Calorimeter (ECAL) is one of the detectors of the Compact Muon Solenoid (CMS) experiment at the CERN Large Hadron Collider (LHC). The ECAL Detector Control System (DCS) software has been implemented using the WinCC Open Architecture (OA) platform. Modifications that require fundamental changes in the architecture are deployed only during the LHC long shutdowns. The upcoming long shutdown (2019-2020) offers a unique opportunity to perform large software updates to achieve a higher modularity, enabling a faster adaptation to changes in the experiment environment. We present the main activities of the ECAL DCS upgrade plan, covering aspects such as the re-organization of the computing infrastructure, the consolidation of integration tools using virtualized environments and the further usage of centralized resources. CMS software toolkits are evaluated from the point of view of the standardization of important parts of the system, such as the machine protection mechanism and graphical user interfaces. Many of the presented features are currently being developed, serving as precursors to the major ECAL upgrade foreseen for the next long shutdown (~2024-2025).

	Funding: The authors would like to thank the Swiss National Science Foundation for the financial support. The CMS Detector Control System (DCS) is implemented as a large distributed and redundant system, with applications interacting and sharing data in multiple ways. The CMS XML-RPC is a software toolkit implementing the standard Remote Procedure Call (RPC) protocol, using the Extensible Mark-up Language (XML) and a custom lightweight variant using the JavaScript Object Notation (JSON) to model, encode and expose resources through the Hypertext Transfer Protocol (HTTP). The CMS XML-RPC toolkit complies with the standard specification of the XML-RPC protocol that allows system developers to build collaborative software architectures with self-contained and reusable logic, and with encapsulation of well-defined processes. The implementation of this protocol introduces not only a powerful communication method to operate and exchange data with web-based applications, but also a new programming paradigm to design service-oriented software architectures within the CMS DCS domain. This paper presents details of the CMS XML-RPC implementation in WinCC Open Architecture (OA) Control Language using an object-oriented approach.

WEP19	TINE Release 5.0 : A First Look	controls, LabView, Windows, operation	77
	P. Duval, J. Szczesny, J.T. Tempel DESY, Hamburg, Germany J. Bobnar Cosylab, Ljubljana, Slovenia M. Nikolova EMBL, Hamburg, Germany S. Weisse DESY Zeuthen, Zeuthen, Germany
	The TINE* control system evolved in great part to meet the needs of controlling a large accelerator the size of HERA, where not only the size of the machine and efficient online data display and analysis were determining criteria, but also the seamless integration of many different platforms and programming languages. Although there has been continuous development and improvement during the operation of PETRA, it has now been 10 years since the last major release (version 4). Introducing a new major release necessarily implies a restructuring of the protocol headers and a tacit guarantee that it be compatible with its predecessors, as any logical deployment and upgrade strategy will entail operating in a mixed environment. We report here on the newest features of TINE Release 5.0 and on first experiences in its initial deployment. * http://tine.desy.de

WEP26	The Development of Vacuum Gauge Monitoring and Control System using Web2CToolkit	vacuum, controls, monitoring, interface	96
	H. Ishii, T. Kosuge, H. Nitani KEK, Ibaraki, Japan
	The Photon Factory is an accelerator-based light source facility, as a part of the High Energy Accelerator Research Organization (KEK) Japan and STARS (Simple Transmission and Retrieval System) is used as the beamline control system at the Photon Factory. STARS is a message transferring software for small scale control systems with TCP/IP sockets, which works on various types of operating systems. STARS is effective for various control systems and we developed Vacuum Gauge Monitoring and Control System with STARS. Web2cToolkit is developed by DESY that provides a user-friendly interface and user can develop Web based GUIs easily with Web2cToolkit. Web2c supports various types of protocol (e. g. TINE, DOOCS, EPICS, TANGO etc.) and the STARS protocol has been supported. We decided to introduce Web2cToolkit as the GUI application on our vacuum gauge monitoring and control system and a few functions are implemented. The development is still in progress.

WEP27	Development of the Malfunctions Detection System at Vepp-2000 Collider	controls, collider, interface, status	99
	O.S. Shubina, A.I. Senchenko, P.Yu. Shatunov BINP SB RAS, Novosibirsk, Russia A.I. Senchenko NSU, Novosibirsk, Russia
	In 2007, the creation of the electron-positron collider VEPP-2000 was completed at the Institute of Nuclear Physics of the SB RAS. VEPP-2000 collider facility consists of various subsystems, and a failure of any subsystem can lead to the incorrect operation of the complex for several hours or even days. Thus, there is a need to create software that, based on the data analysis, will warn about possible malfunctions. To accomplish the task, software was developed consisting of three modules. The first performs automatic verification of compliance data obtained from the accelerator complex and rules describing the correct subsystems operation. The second module is a user-friendly web interface that displays information about the state of the complex in a convenient way. The third module acts as some intermediary between the first and the second. It processes messages arriving at the message queue and redirects them to all subscribed clients via the web socket. This article is devoted to the development of test software, which is currently running on the VEPP-2000 control panel.

WEP28	Development of Software for Accessing the Vepp-2000 Collider Facility Archiving System	interface, collider, controls, database	102
	O.S. Shubina, A.I. Senchenko, P.Yu. Shatunov BINP SB RAS, Novosibirsk, Russia A.I. Senchenko NSU, Novosibirsk, Russia
	The VEPP-2000 is an electron-positron collider, that was commissioned at Budker Institute of Nuclear Physics. The VEPP-2000 acceleration complex consists of a few main subsystems: BEP booster ring and VEPP-2000 collider ring. Data from accelerator complex are recorded regularly with a frequency at 1 Hz. There is often a need to obtain already stored data for analysis or modeling. In addition, you must provide remote data access to optimize the workflow. The solution of this problem must be universal, and it must be easily adapted to various databases and installation modes. To solve the task, the software was developed based on the client-server architecture. The server part is responsible for processing data in automatic mode according to the developed algorithm. The client part allows to view the data in a user-friendly form. This article talks about the development of software, simplifying access to the VEPP-2000 archiving system, that is launched on the VEPP-2000 control panel.

THCA4	Development of a Network-based Timing and Tag Information Distribution System for Synchrotron Radiation Experiments at SPring-8	timing, FPGA, network, experiment	131
	T. Masuda JASRI/SPring-8, Hyogo, Japan
	Time-resolved measurements in synchrotron radiation experiments require an RF clock of a storage ring accelerator and a fundamental revolution frequency (zero address) signal. For the usage of these signals around the experimental station, long RF cables from the accelerator timing station, divider modules and delay modules must be deployed. These installations need a lot of cost and require a lot of efforts to adjust the timing by experts. To lower these costs and efforts, the revolution frequency, which is ~209 kHz at the SPring-8 storage ring, and tag information distribution system has been studied based on a high precision time synchronization technology over a network. In this study, the White Rabbit* (WR) technology is adopted. The proof of concept system has been built, which consists of a master PC, a slave PC and two WR switches. The master PC detects the zero-address signal and distributes the time stamps with tag information to the slave PC. Then the slave PC generates the ~209 kHz signals synchronized with the target bunch by adding the offset time by software. The measured one-σ jitter of the output signals from the slave PC has been achieved less than 100 ps. * https://www.ohwr.org/projects/white-rabbit

THCA5	Rethinking PLCs: Industrial Ethernet for Large-Scale Real-Time Distributed Control Applications	PLC, controls, hardware, network	136
	B. Plötzeneder, O. Janda, A. Kru’enko, J. Trdlicka ELI-BEAMS, Prague, Czech Republic P. Bastl Institute of Physics of the ASCR, Prague, Czech Republic
	Funding: Extreme Light Infrastructure - Phase 2 (CZ.02.1.01/ 0.0/0.0/15₀08/0000162; Ministry of Education, Youth and Sports CZ / European Regional Development Fund) Many research facilities rely on PLCs to automate large slow systems like vacuum or HVAC, where price, availability and reliability matter. The dominant architecture consists of local units of controllers/ modules (programmed in IEC61131-3 languages), which operate mostly autonomously from a SCADA layer. While some vendors provide low-level stacks to encourage growth of their ecosystems, PLC programming remains largely within a closed, proprietary world. In this paper, we introduce a different way of thinking about PLC hardware. Working with the open stacks intended for the design of new EtherCAT (Beckhoff) / Powerlink (B&R) modules, we built an abstract C+± API to control the existing ones. These industrial ethernet busses can be propagated using standard network hardware, so any RT-Linux system can now control any PLC module from anywhere in our facility using high-level languages (C++, LabVIEW). This way, PLC modules are seamlessly integrated into our distributed TANGO-based control system. PC-PLC interfaces are no longer needed; or in the case of traditionally implemented subsystems (machine safety), trivial.

THCB4	Leveraging Internet of Things Developments for Rapid Prototyping of Synoptic Displays	controls, HOM, EPICS, interface	151
	L.T. Stant, T.M. Cobb DLS, Oxfordshire, United Kingdom
	Recently the technology industry has been laying foundations for the eponymous Internet of Things (IoT): efficient publish-subscribe protocols; process control schemas for household items; and improved low-power radio communications. Accelerator controls and IoT have several aspects in common - small payloads, low latency, dashboard/synoptic data presentation format are some examples. The IoT now provides several open-source projects which can provide a partial implementation of one or more accelerator controls software features. Because development is typically a lower priority for accelerator controls groups, there is a valid case to try and utilise the free efforts of others for the benefit of accelerator controls. In this paper, the authors present examples of the use of IoT frameworks for synoptic display/GUI development. The work in this paper enables other developers to access this resource and experiment with their own systems.

THP08	Design and Implementation of Stepper Motor Control of the LINAC High Power RF System Based on FPGA	controls, GUI, FPGA, electron	179
	R. Rujanakraikarn, Ch. Dhammatong, W. Phacheerak SLRI, Nakhon Ratchasima, Thailand
	In this paper, the new motion control system that governs the position of high power attenuators and phase shifters in the linac’s RF system at SLRI is described. The drive system, which was originally driven by a set of AC reversible motors, is replaced by a new set of stepper motors. The hardware selection and installation is presented in detail. The digital control circuits are designed in VHDL and implemented on a commercial Field Programmable Gate Array (FPGA) board. The main software part, implemented in MicroBlaze Microcontroller System (MCS), is coded in C to control the position of stepper motors relative to the DC voltage reference points of the hardware system. A LabVIEW GUI is designed to interface with the control system to provide reference points and display position values via RS-232 and PLC interfaces. This stepper motor control system can be used to effectively implement the phase and amplitude control system of the linac’s RF signals in the future.

	R. Rujanakraikarn, P. Koonpong, S. Tesprasitte SLRI, Nakhon Ratchasima, Thailand
	A prototype of the 6-MeV medical linear accelerator has been under development at Synchrotron Light Research Institute (SLRI). A set of secondary collimators is utilized with different size arrangement for beam shaping purpose. To produce the desired field size of the beam, the FPGA-based collimator motion control is designed in VHDL for simultaneous control of the collimators while the main PI control is implemented in the FPGA’s main processor. In this paper, hardware and software upgrades of the collimator motion control system are presented. A custom drive hardware for individual collimator is designed to implement with the existing FPGA controller board. Interface between the custom hardware parts and the FPGA’s programmable logic (PL) part is described. Communication between the motion control subsystem and the main LabVIEW control software on PC is modified to send and receive parameters wirelessly. Software modification of the FPGA’s main processor part and that of the LabVIEW GUI part is also reported.

	Funding: Work supported by National Natural Science Foundation of China (No.11375186) A data warehouse based on Hadoop ecosystem is designed and constructed for Hefei Light Source II (HLS-II). The ETL program based on Spark migrates data to HDFS from RDB Channel Archiver and the EPICS Archiver Appliance continuously and store them in Parquet format. The distributed data analysis engine based on Impala greatly improves the performance of data retrieval and reduces the response time of queries. In this paper, we will describe our efforts and experience to use various open sources software and tools to effectively manage the big data. We will also report the plans on this data warehouse in the future.

	Funding: This project is funded by Brookhaven Science Associates. BSA is a partnership between Battelle and The Research Foundation for the State University of New York on behalf of Stony Brook University. The purpose of this project is to demonstrate the performance improvements on insertion devices by upgrading the motion control software. The insertion devices installed inside the NSLS-II storage ring are currently operating at micron precision with slow speeds, which can limit the scope of preferences for user experimentation. We can manipulate the devices with adaptive tuning algorithms to compensate for varying electromagnetic forces throughout motion scans. By correcting positional feedback with encoder compensation and redefining motion programs, we can safely increase the speed to run the same motion trajectories in less time.

Designing, implementing and maintaining process control systems for cryogenic plants requires different viewpoints compared with those in machine controls. 24/7 operations for more than a year is a basic requirement. Hardware and software must be designed to fulfill this requirement. Many projects are carried out with industrial partners. Companies specify the process control logic which gets implemented by the local DESY team. Responsibilities, time tables and milestones must be clearly defined in such a case. Several cryogenic installations have been equipped with state of the art process control systems for cryogenic controls. Where the last one being the European XFEL. In the course of time commercial and open source systems were implemented and maintained. Control loops were basically always implemented in front end controllers running the real-time operating system VxWorks and EPICS as the control system toolkit. The approach to use PLCs will be discussed as an alternative approach. Large installations like the European XFEL require good project planning. Our success story will finalize our look back and initiate our look forward.

The high-gain free electron lasers have given scientists hopes for new scientific discoveries in many frontier research areas. The Shanghai HIgh repetition rate XFEL aNd Extreme light facility (SHINE) was proposed by the central government of P.R. China on April 2017, which is a quasi-continuous wave hard X-ray free electron laser facility. The control system is responsible for the facility-wide device control, data acquisition, machine protection, high level database or application, as well as network and computing platform. It will be mainly based on EPICS to reach the balance between the high performance and costs of maintenance. The latest technology will be adopted for the high repetition rate data acquisition and feedback system. The details of the control system design will be reported in this paper.

CERN, Meyrin, Switzerland

GUI for supervision, control and data acquisition systems are usually oriented to specialist users. In big organizations like CERN, where different teams play the roles of operators, scientists and instrumentation specialists, providing a unique or static user interface usually results in a situation of dissatisfaction of everyone. On the other hand, providing distinct user interfaces for each type of user increases the development and maintenance effort and makes software evolution heavier. The approach taken for the design and development of GUIs for radiation and environment protection at CERN addressed this issue by integrating user interface changes as an embedded software functionality. Key users were provided with a tool to build, deploy and maintain their own tailor-made user interfaces, in a graphical way and without the necessity of learning any kind of programming or scripting languages. Other benefits observed from this solution include reduction of the resources spent on the support and maintenance and increase of the frequency of GUIs updates, executed without compromising the underlying control system. This paper describe the innovative design that was implemented.

One of the heaviest workloads when installing a Control System on a plant is the development of a large number of device drivers. This is even more true in the case of scientific facilities for which you typically deal with many custom devices and legacy code. In these cases, it is useful to consider the Rapid Application Development (RAD) approach that consists in lessen the planning phase and give more emphasis on an adaptive process, so that software prototypes can be successfully used in addition to or in place of design specifications. LabVIEW* is a typical RAD-oriented development tool and is widely used in technical laboratories where many stand-alone programs are developed to manage devices under construction or evaluation. An original system that allows software clients to use external LabVIEW drivers is presented. This system, originally created for the !CHAOS Control System**, is entirely written in LabVIEW and is based on JSON messages -transmitted on a WebSocket communication- driving LabVIEW VIs through dynamic calls. This system is completely decoupled from the client and is therefore suitable for any Control System.

The main driving part of the X-ray free electron laser facility (SwissFEL) at the Paul Scherrer Institute (PSI) is a compact electron linear accelerator (linac). The machine is highly optimized to generate a superior FEL radiation with the lowest suitable electron beam energy. In order to meet extremely stringent SwissFEL requirements for electron beam quality and stability, a variety of beam diagnostics tools were developed and implemented at the PSI. All these tools are integrated into the SwissFEL control system. The paper describes basic control elements of the electron beam diagnostics tools and their operational performance.

The Electromagnetic Calorimeter (ECAL) is one of the detectors of the Compact Muon Solenoid (CMS) experiment at the CERN Large Hadron Collider (LHC). The ECAL Detector Control System (DCS) software has been implemented using the WinCC Open Architecture (OA) platform. Modifications that require fundamental changes in the architecture are deployed only during the LHC long shutdowns. The upcoming long shutdown (2019-2020) offers a unique opportunity to perform large software updates to achieve a higher modularity, enabling a faster adaptation to changes in the experiment environment. We present the main activities of the ECAL DCS upgrade plan, covering aspects such as the re-organization of the computing infrastructure, the consolidation of integration tools using virtualized environments and the further usage of centralized resources. CMS software toolkits are evaluated from the point of view of the standardization of important parts of the system, such as the machine protection mechanism and graphical user interfaces. Many of the presented features are currently being developed, serving as precursors to the major ECAL upgrade foreseen for the next long shutdown (~2024-2025).

The CMS Detector Control System (DCS) is implemented as a large distributed and redundant system, with applications interacting and sharing data in multiple ways. The CMS XML-RPC is a software toolkit implementing the standard Remote Procedure Call (RPC) protocol, using the Extensible Mark-up Language (XML) and a custom lightweight variant using the JavaScript Object Notation (JSON) to model, encode and expose resources through the Hypertext Transfer Protocol (HTTP). The CMS XML-RPC toolkit complies with the standard specification of the XML-RPC protocol that allows system developers to build collaborative software architectures with self-contained and reusable logic, and with encapsulation of well-defined processes. The implementation of this protocol introduces not only a powerful communication method to operate and exchange data with web-based applications, but also a new programming paradigm to design service-oriented software architectures within the CMS DCS domain. This paper presents details of the CMS XML-RPC implementation in WinCC Open Architecture (OA) Control Language using an object-oriented approach.

The TINE* control system evolved in great part to meet the needs of controlling a large accelerator the size of HERA, where not only the size of the machine and efficient online data display and analysis were determining criteria, but also the seamless integration of many different platforms and programming languages. Although there has been continuous development and improvement during the operation of PETRA, it has now been 10 years since the last major release (version 4). Introducing a new major release necessarily implies a restructuring of the protocol headers and a tacit guarantee that it be compatible with its predecessors, as any logical deployment and upgrade strategy will entail operating in a mixed environment. We report here on the newest features of TINE Release 5.0 and on first experiences in its initial deployment.

The Photon Factory is an accelerator-based light source facility, as a part of the High Energy Accelerator Research Organization (KEK) Japan and STARS (Simple Transmission and Retrieval System) is used as the beamline control system at the Photon Factory. STARS is a message transferring software for small scale control systems with TCP/IP sockets, which works on various types of operating systems. STARS is effective for various control systems and we developed Vacuum Gauge Monitoring and Control System with STARS. Web2cToolkit is developed by DESY that provides a user-friendly interface and user can develop Web based GUIs easily with Web2cToolkit. Web2c supports various types of protocol (e. g. TINE, DOOCS, EPICS, TANGO etc.) and the STARS protocol has been supported. We decided to introduce Web2cToolkit as the GUI application on our vacuum gauge monitoring and control system and a few functions are implemented. The development is still in progress.

In 2007, the creation of the electron-positron collider VEPP-2000 was completed at the Institute of Nuclear Physics of the SB RAS. VEPP-2000 collider facility consists of various subsystems, and a failure of any subsystem can lead to the incorrect operation of the complex for several hours or even days. Thus, there is a need to create software that, based on the data analysis, will warn about possible malfunctions. To accomplish the task, software was developed consisting of three modules. The first performs automatic verification of compliance data obtained from the accelerator complex and rules describing the correct subsystems operation. The second module is a user-friendly web interface that displays information about the state of the complex in a convenient way. The third module acts as some intermediary between the first and the second. It processes messages arriving at the message queue and redirects them to all subscribed clients via the web socket. This article is devoted to the development of test software, which is currently running on the VEPP-2000 control panel.

The VEPP-2000 is an electron-positron collider, that was commissioned at Budker Institute of Nuclear Physics. The VEPP-2000 acceleration complex consists of a few main subsystems: BEP booster ring and VEPP-2000 collider ring. Data from accelerator complex are recorded regularly with a frequency at 1 Hz. There is often a need to obtain already stored data for analysis or modeling. In addition, you must provide remote data access to optimize the workflow. The solution of this problem must be universal, and it must be easily adapted to various databases and installation modes. To solve the task, the software was developed based on the client-server architecture. The server part is responsible for processing data in automatic mode according to the developed algorithm. The client part allows to view the data in a user-friendly form. This article talks about the development of software, simplifying access to the VEPP-2000 archiving system, that is launched on the VEPP-2000 control panel.

T. Masuda
JASRI/SPring-8, Hyogo, Japan

Time-resolved measurements in synchrotron radiation experiments require an RF clock of a storage ring accelerator and a fundamental revolution frequency (zero address) signal. For the usage of these signals around the experimental station, long RF cables from the accelerator timing station, divider modules and delay modules must be deployed. These installations need a lot of cost and require a lot of efforts to adjust the timing by experts. To lower these costs and efforts, the revolution frequency, which is ~209 kHz at the SPring-8 storage ring, and tag information distribution system has been studied based on a high precision time synchronization technology over a network. In this study, the White Rabbit* (WR) technology is adopted. The proof of concept system has been built, which consists of a master PC, a slave PC and two WR switches. The master PC detects the zero-address signal and distributes the time stamps with tag information to the slave PC. Then the slave PC generates the ~209 kHz signals synchronized with the target bunch by adding the offset time by software. The measured one-σ jitter of the output signals from the slave PC has been achieved less than 100 ps.

Many research facilities rely on PLCs to automate large slow systems like vacuum or HVAC, where price, availability and reliability matter. The dominant architecture consists of local units of controllers/ modules (programmed in IEC61131-3 languages), which operate mostly autonomously from a SCADA layer. While some vendors provide low-level stacks to encourage growth of their ecosystems, PLC programming remains largely within a closed, proprietary world. In this paper, we introduce a different way of thinking about PLC hardware. Working with the open stacks intended for the design of new EtherCAT (Beckhoff) / Powerlink (B&R) modules, we built an abstract C+± API to control the existing ones. These industrial ethernet busses can be propagated using standard network hardware, so any RT-Linux system can now control any PLC module from anywhere in our facility using high-level languages (C++, LabVIEW). This way, PLC modules are seamlessly integrated into our distributed TANGO-based control system. PC-PLC interfaces are no longer needed; or in the case of traditionally implemented subsystems (machine safety), trivial.

DLS, Oxfordshire, United Kingdom

Recently the technology industry has been laying foundations for the eponymous Internet of Things (IoT): efficient publish-subscribe protocols; process control schemas for household items; and improved low-power radio communications. Accelerator controls and IoT have several aspects in common - small payloads, low latency, dashboard/synoptic data presentation format are some examples. The IoT now provides several open-source projects which can provide a partial implementation of one or more accelerator controls software features. Because development is typically a lower priority for accelerator controls groups, there is a valid case to try and utilise the free efforts of others for the benefit of accelerator controls. In this paper, the authors present examples of the use of IoT frameworks for synoptic display/GUI development. The work in this paper enables other developers to access this resource and experiment with their own systems.

In this paper, the new motion control system that governs the position of high power attenuators and phase shifters in the linac’s RF system at SLRI is described. The drive system, which was originally driven by a set of AC reversible motors, is replaced by a new set of stepper motors. The hardware selection and installation is presented in detail. The digital control circuits are designed in VHDL and implemented on a commercial Field Programmable Gate Array (FPGA) board. The main software part, implemented in MicroBlaze Microcontroller System (MCS), is coded in C to control the position of stepper motors relative to the DC voltage reference points of the hardware system. A LabVIEW GUI is designed to interface with the control system to provide reference points and display position values via RS-232 and PLC interfaces. This stepper motor control system can be used to effectively implement the phase and amplitude control system of the linac’s RF signals in the future.

A prototype of the 6-MeV medical linear accelerator has been under development at Synchrotron Light Research Institute (SLRI). A set of secondary collimators is utilized with different size arrangement for beam shaping purpose. To produce the desired field size of the beam, the FPGA-based collimator motion control is designed in VHDL for simultaneous control of the collimators while the main PI control is implemented in the FPGA’s main processor. In this paper, hardware and software upgrades of the collimator motion control system are presented. A custom drive hardware for individual collimator is designed to implement with the existing FPGA controller board. Interface between the custom hardware parts and the FPGA’s programmable logic (PL) part is described. Communication between the motion control subsystem and the main LabVIEW control software on PC is modified to send and receive parameters wirelessly. Software modification of the FPGA’s main processor part and that of the LabVIEW GUI part is also reported.

A data warehouse based on Hadoop ecosystem is designed and constructed for Hefei Light Source II (HLS-II). The ETL program based on Spark migrates data to HDFS from RDB Channel Archiver and the EPICS Archiver Appliance continuously and store them in Parquet format. The distributed data analysis engine based on Impala greatly improves the performance of data retrieval and reduces the response time of queries. In this paper, we will describe our efforts and experience to use various open sources software and tools to effectively manage the big data. We will also report the plans on this data warehouse in the future.

Funding: This project is funded by Brookhaven Science Associates. BSA is a partnership between Battelle and The Research Foundation for the State University of New York on behalf of Stony Brook University.
The purpose of this project is to demonstrate the performance improvements on insertion devices by upgrading the motion control software. The insertion devices installed inside the NSLS-II storage ring are currently operating at micron precision with slow speeds, which can limit the scope of preferences for user experimentation. We can manipulate the devices with adaptive tuning algorithms to compensate for varying electromagnetic forces throughout motion scans. By correcting positional feedback with encoder compensation and redefining motion programs, we can safely increase the speed to run the same motion trajectories in less time.
