WEC1	The Do’s and Don’ts in Process Controls - Lessons Learned Over 35 Years	PLC, software, 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.

	!CHAOS* (Control system based on Highly Abstracted and Open Structure) is now mature and is being employed in real operational contexts. A dedicated infrastructure, recently installed at the LNF Computer Centre, houses the framework and provides control services to different LNF installations. The !CHAOS native capability of fast storage, based on the use of a non-relational database, has been finalized and tested with applications demanding high bandwidth. Thanks to its scalable design, the fast storage allows to accommodate multiple sources with sub-millisecond timing. The EU (Execution Unit) node has also been delivered and turned out to be a "Swiss Army knife" for processing both live and stored data, inserting feedbacks and in general for correlating data acquired by the CU (Control Units) nodes. A key feature of the EU is a plugin mechanism that allows to easily integrate different programming and scripting languages such as LUA, C++, Python, also exploiting the ROOT framework, the well-known scientific tool from CERN. A comprehensive description of the !CHAOS evolution, of its performances and of its use, both in scientific and industrial contexts, is presented. * L. Catani et al, Phys. Rev. ST Accel.

WEP01	EtherCAT Driver and Tools for EPICS and Linux at PSI	EPICS, real-time, Linux, PLC	22
	D. Maier-Manojlovic PSI, Villigen PSI, Switzerland
	EtherCAT bus and interface are widely used for external module and device control in accelerator environments at PSI, ranging from modulator and undulator communication and control, over motion control, basic I/O control, all the way to Machine Protection System for the new SwissFEL accelerator. A combined EPICS/Linux driver package has been developed at PSI, to allow for simple and mostly automatic setup of various EtherCAT configurations. The driver is capable of automatic scan of the existing devices and modules, followed by self-configuration and finally autonomous operation of the EtherCAT bus real-time loop. Additionally, the driver package supports the user PLC to manipulate EtherCAT data in real time, implements fast real-time (single cycle) slave-to-slave communication (skipping EPICS layer or PLC completely), features guaranteed one-shot trigger signals otherwise not supported by EPICS and much more. All the standard EtherCAT functions are supported, including the complete reprogramming of slave configurations and configuration generation for programmable slaves, such as EL6692 and EL6695 network bridges.

WEP04	Developing and Validating OPC-UA Based Industrial Controls for Power Supplies at CERN	electron, simulation, electronics, power-supply	35
	M. Ludwig, J.A.R. Arroyo Garcia, M. Bengulescu, B. Farnham, P.G.J. Gonzalez Jimenez, F. Varela CERN, Meyrin, Switzerland
	The industrial control systems of CERN’s experiments are undergoing major renovation since 2017 and well into CERN’s second Long Shutdown (LS2) until the end of 2019. Each detector power-supply control system runs several hundred software instances consisting of many different components in parallel on a large scale, broadly distinguishable as servers and clients. Our accumulated experience during LHC runs proves that some complex control issues are impossible to detect using stand-alone components on a small scale only. Furthermore, new components must be developed well before the electron-ics becomes available, without impact on operations. Moreover, during LS2, the improved and now widely established Open Protocol Communication Unified Ar-chitecture (OPC-UA) replaces OPC-DA as middleware protocol. For these reasons, we developed a simulation environment to emulate the real, and valuable, CAEN power-supply electronics underneath the OPC-UA serv-ers. This distributed simulation is configurable to mimic and exceed the nominal conditions during production and provides a repeatable setup for validation. This paper discusses the functionality and use of this simulation service.

WEP07	Innovative Graphical User Interfaces Development: Give the Power Back to Users	GUI, interface, software, 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, software, 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.

WEP13	Control System Upgrade for the FFAG Accelerator Complex at KURNS	EPICS, PLC, FFAG, LabView	60
	Y. Kuriyama, Y. Fuwa, Y. Ishi, Y. Mori, H. Okita, T. Uesugi Kyoto University, Research Reactor Institute, Osaka, Japan
	Fixed field alternating gradient (FFAG) accelerator complex has been operated as a proton driver for the experiment of accelerator driven system (ADS) at Institute for Integrated Radiation and Nuclear Science, Kyoto University (KURNS). PLC based control system has been developed and the operator interface has been connected to PLC via network. Originally, a LabVIEW based operational interface was chosen to construct the system because of its easiness. However we met an upgrade problem, and a new control system based on EPICS instead of LabVIEW was introduced in 2010. In the spring of 2018, the replacement from LabVIEW to EPICS has been almost completed except for the beam interlock system and the LINAC control system provided by LINAC production company (AccSys). Also, the EPICS archiving tool (Archiver Appliance) has been invoked and operated at the end of 2017. This Presentation reports the details of the current control system and also the upgraded GPIB control and storage system. Formerly, Kyoto University Research Reactor Institute (KURRI).

	The Taiwan Photon Source (TPS) is a 3 GeV storage ring. A NI C-RIO controller, basic to the real-time, EPICS program, is used and designed such as to maintain ultra-high vacuum conditions and protect vacuum components. Pressure readings from ionization gauges are taken as the logic signal to control sector gate valves to protect ultra-high vacuum condition. Monitoring of vacuum components, water-cooling systems and chamber temperatures serves to protect vacuum equipment from radiation power. The evolution and status of the control system is presented in this paper.

WEP15	Recent Development of the RIKEN RI Beam Factory Control System	power-supply, operation, EPICS, cyclotron	66
	M. Komiyama, M. Fujimaki, N. Fukunishi, K. Kumagai, A. Uchiyama RIKEN Nishina Center, Wako, Japan
	We report on development of the successor of the existing controller device used for the magnet power supplies in the RIKEN Radioactive Isotope Beam Factory (RIBF). The existing controller for the magnet power supplies is operated in the Versa Module European (VME) computing machines under the Experimental Physics and Industrial Control System (EPICS) framework. The present controller has been operated stably for more than 10 years, however, it is now commercially unavailable because supply of some parts has been already terminated. In 2016, we developed a successor to have the same function essentially as the existing one, but it is designed to run in control systems constructed by programmable logic controller (PLC) modules instead of the VME computing environment, in order to achieve cost reduction and functional scalability. We confirmed that the successor was successfully controlled by using a test system. And now, we are developing a control system that can flexibly add new functions through actual operation while having all the existing functions. We will introduce the successor to the new injector LINAC system this year.

WEP16	CMS ECAL Detector Control System Upgrade Plan for the CERN Large Hadron Collider Long Shutdown II	software, detector, interface, framework	69
	R.J. Jiménez Estupinan, D.R.S. Di Calafiori, G. Dissertori, L. Djambazov, W. Lustermann, S. Zelepoukine ETH, Zurich, Switzerland
	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	LabView, Windows, software, 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

Trowitzsch DESY Zeuthen, Zeuthen, Germany M. Otevřel CEITEC, BUT, Brno, Czech Republic Y. Renier DPNC, Genève, Switzerland G. Vashchenko DESY, Hamburg, Germany
	The Photo Injector Test Facility at DESY in Zeuthen (PITZ) was built to test and to optimize sources of high brightness electron beams for Free-Electron Lasers (FELs). In order to achieve high accelerating gradients and long RF pulse lengths in the RF gun cavities an extensive and safe RF conditioning is required. A State Machine based Automatic Conditioning application (SMAC) was developed to automate the RF conditioning processes, allowing for greater efficiency and performance optimization. SMAC is written in Java and uses State Chart XML (SCXML) as the finite-state machine execution environment based on Harel statecharts. It employs the Distributed Object-Oriented Control System (DOOCS) and Three-fold Integrated Networking Environment (TINE) for the communication with the control system of PITZ. The graphical user interface (GUI) is created by using the Java Swing toolkit. Communication between GUI and SXML processing layer is performed via Document Object Model (DOM) events. The SMAC application has been successfully applied to RF conditioning of several gun cavities at PITZ.

WEP26	The Development of Vacuum Gauge Monitoring and Control System using Web2CToolkit	vacuum, monitoring, interface, software	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	software, 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	software, interface, collider, 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.

	In RIBF project, a superconducting linac will be implemented in order to enhance the beam energy necessary for promoting super heavy element experiment. A new 28 GHz electron resonance ion source has been installed upstream of them. Its control system will be consisted of Yokogawa FA-M3 series which is a porgrammble logic controller (PLC) with EPICS because of many achievements in case of RIBF control system. On the other hand, in the previous system with PLCs there was a disadvantage of low reliability for communications between PLC stations. Additionally, some devices (eg, oven, mivoc etc.) are changed for the generation of various kind of ions each times, therefore higher expandability is required. In the new system, we have designed the control system by utilizing star topology fieldbus for communications between the PLC stations to establish safety and expandability. In this conference, we report on the details of the system.

WEP31	Design of PLC Temperature Flow Acquisition System Based on EPICS	rfq, PLC, EPICS, interface	109
	H. Zheng, H. Cao, Y.X. Chen IMP/CAS, Lanzhou, People’s Republic of China
	In the design of the ADS injector II, the RFQ cavity holds a supreme status, and the RFQ temperature and flow information are the key parameters for the cavity frequency tuning. To ensure the long-term, stable and accurate acquisition of temperature flow data is the core task of control. In this paper, the PLC temperature flow acquisition system which is based on EPICS design was described, and the EPICS driver of this PLC was developed independently. The driver uses TCP/IP connection to EPICS IOC, and the communication protocol uses the "data block overall transmission protocol", to ensure the stability of the device’s data communications. After 3 months of long-term operation inspection, this acquisition system can ensure long-term and stable acquisition of real-time temperature and flow data of the equipment, and be able to send control information to related controlled equipment. In addition, redundant PLCs and redundant IOCs were adopted in this acquisition system to make the switch to alternate channels within milliseconds once a channel fails.

	Building a high power spallation target is one of the critical issues in Accelerator Driven System (ADS). The control system which was built based on the real-time distributed control software of experimental physics and industrial control system (EPICS) was attempted for the experimental target prototype. There are several sub-systems in the target system, e.g. the elevating system, the vacuum system, the heat-exchanging system. As an IOC, each sub-system was finally integrated into the control system of the target by different drivers and methods because different hardware devices were used for each sub-system. The ’SLS s7 driver’ which was devel-oped based on the Ethernet Interface was used for the communication between the Siemens PLCs and the Hu-man Machine Interface (HMI). The interfaces between Labview and EPICS were used for the NI (Nation-al Instruments) DAQs systems. In addition, the driver developed by ourselves was used for devices with serial ports, e.g. RS-232 or RS-485/422. The control system was finally proved stable and could basically meet the ele-mentary requirements of the spallation target system.

THCA1	Quest for the New Standard PSI IOC Platform	EPICS, Linux, FPGA, operation	119
	D. Anicic PSI, Villigen PSI, Switzerland
	With its four accelerator facilities the Paul Scherrer Institut (PSI) has already several decades of control system Input Output Computer (IOC) experience. The technology is moving forward fast. The older hardware is becoming obsolete: it is slow, consumes too much power, does not match new computing, networking and bus technologies, and replacements can no longer be purchased as models have been discontinued. All this forces us to opt for a new "standard" IOC platform with increasing regularity. What used to be twenty years, became ten, and is now tending towards five years. Here we present past and possible future IOC platforms which we are investigating. Feedback from the conference would be highly appreciated.

THCA2	Development of MicroTCA-based Low-level Radio Frequency Control Systems for cERL and STF	cavity, LLRF, FPGA, linac	124
	F. Qiu, T. Matsumoto, S. Michizono, T. Miura KEK, Ibaraki, Japan
	Low-level radio frequency (LLRF) control systems based on µTCA standard have been developed for facilities such as compact energy recovery linac (cERL) and superconducting test facility (STF) at the High Energy Accelerator Research Organization (KEK), Japan. Three different types of boards were developed according to their different applications. Experimental physics and industrial control system (EPICS) was selected as the data communication system for all of these µTCA boards. The LLRF systems showed good performance during the beam commissioning. This paper presents the current status of the µTCA-based LLRF systems in the cERL and STF.

	C.H. Huang, Y.-S. Cheng, P.C. Chiu, K.T. Hsu, K.H. Hu, C.Y. Wu NSRRC, Hsinchu, Taiwan
	For a low-emittance photon light source like the Taiwan Photon Source (TPS), beam stability is a very important property for high-quality photon beams. It is, however, hard to completely remove beam disturbing effects. Therefore, a feedback/feedforward system becomes an effective tool to suppress beam motion. In this report, we discuss the performance of such a system implemented at the TPS. The component performance of the feedback system has been tested to understand its bandwidth limitations.

THCA5	Rethinking PLCs: Industrial Ethernet for Large-Scale Real-Time Distributed Control Applications	PLC, hardware, software, 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.

THCB1	ACOP. NET : Not Just Another GUI Builder	GUI, MMI, site, interface	139
	J. Szczesny, P. Duval, M. Lomperski, H. Wu DESY, Hamburg, Germany J. Bobnar Cosylab, Ljubljana, Slovenia T. Kosuge KEK, Ibaraki, Japan
	ACOP (Advanced Component Oriented Programming) tools have been useful in control system GUI application development for some time, originally as an ActiveX component offering a transport layer and a multi-faceted chart * and then later as a suite of components in the Java world *. We now present a set of ACOP components for development in .NET. And where the emphasis in the past has been primarily on rapid application development of rich clients, this new palette of components is designed both for fully featured rich-client development in any of the .NET supported languages (C#, C++, VB, F#) as well as for fully configurable clients (with design-time browsing), where no programming on the part of the developer is necessary, and of course for any combination between these extremes. This is an important point, which will become clear when we contrast application development with ACOP. NET with other control system GUI builders such as Control System Studio and jddd. Although Visual Studio is the GUI builder of choice, we will present other available options, for example on Linux. Examples using transport plugs for TINE and STARS will be given. I.

	T. Kosuge, H. Ishii, Y. Nagatani, H. Nitani KEK, Ibaraki, Japan P. Duval, J. Szczesny DESY, Hamburg, Germany
	STARS is an extremely simple and very flexible control software for small scale control systems with TCP/IP sockets, which is used as the beamline control system and so on at the KEK Photon Factory (KEK-PF). STARS works on various operating system and the STARS client developer can choose his or her favorite programing language. Choosing .NET is very common to develop GUI applications of beamline control at the KEK-PF. ACOP (Advanced Component Oriented Programming) is very useful for GUI development, which is developed by DESY and a .NET version of ACOP was recently developed. ACOP has a transport layer and communicate with various system through this layer. Now, we have started development of STARS transport layer of ACOP .NET and succeeded in adding very primitive functionality. The development of ACOP .NET STARS transport layer is still ongoing.

THCB3	Improving Web2cHMI Gesture Recognition Using Machine Learning	toolkit, interface, extraction, TANGO	148
	R. Bacher DESY, Hamburg, Germany
	Web2cHMI is multi-modal human-machine interface which seamlessly incorporates actions based on various interface modalities in a single API, including finger, hand and head gestures as well as spoken commands. The set of native gestures provided by off-the-shelf 2D- or 3D-interface devices such as the Myo gesture control armband can be enriched or extended by additional custom gestures. This paper discusses a particular method and its implementation in recognizing different finger, hand and head movements using supervised machine learning algorithms including a non-linear regression for feature extraction of the movement and a k-nearest neighbor method for movement classification using memorized training data. The method is 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, which can then be associated with specific user interactions.

THCB4	Leveraging Internet of Things Developments for Rapid Prototyping of Synoptic Displays	HOM, EPICS, interface, software	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.

THP02	Current Status of the RAON Machine Protection System Development	operation, PLC, machine-protect, target	160
	H. Jin, Y. Choi, S. Lee IBS, Daejeon, Republic of Korea
	For the RAON accelerator that transport beams with high energy and power, a machine protection system (MPS) that protects each device from sudden beam loss is necessary. For this reason, we have been preparing for the development of the MPS with the start of the RAON accelerator construction. For effective MPS operation and stable accelerator operation, we divided the MPS into four subsystems: fast protection system, slow interlock system, run permit system, and post-mortem system. Among them, the FPGA-based fast protection system and the PLC-based slow interlock system have been tested by prototypes and are currently working on the mass production. The run permit system and the post-mortem system are also undergoing basic design and software development. In this paper, we will describe the progress of the MPS development through detailed hardware and software development in the RAON accelerator and explain the future plans.

THP06	Reliability Improvement for the Insertion Device Control in the TPS	EPICS, insertion, radiation, insertion-device	173
	C.Y. Wu, J. Chen, Y.-S. Cheng, K.T. Hsu, K.H. Hu, C.Y. Liao NSRRC, Hsinchu, Taiwan
	Insertion devices (ID) are essential components in third-generation synchrotron light sources, which can produce highly-brilliant, collimated and quasi-monochromatic radiation over a broad energy range for experiments. Reliable operation of the insertion devices is important to users of beamlines. The most unpredictable fault is due to a soft error in optical absolute encoders due to radiation. There are several solutions to avoid such faults, e.g. by increasing the distance of the encoder from the beam, by a lead shield cover and finally by adopting an auxiliary position sensing devices to help recovery from a fault. Efforts to improve operational reliability of the TPS ID controls will be discussed.

	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.

	IFMIF (International Fusion Materials Irradiation Facility) Prototype Accelerator (LIPAc) has been developed, which is designed to produce a deuteron CW beam with a current of 125 mA at 9 MeV. After the injector commissioning, the LIPAc is entering in the second commissioning phase in which RFQ, MEBT, RF Power System and Beam Instrumentation (BI) systems have been integrated. The LCSs of LIPAc have been developed by European Home Team (EU-HT) and delivered with its subsystems; the CCS, including personnel and machine protection, timing, archiving and alarming, by Japanese Home Team (JA-HT). These have been implemented on the EPICS platform to mitigate the risk of incompatibility in the integration, which JA-HT and EU-HT are jointly carrying out to control the whole accelerator. In the CCS, some interlocks associated with measurement systems–chopper interlock, protection of BI systems, etc.–are implemented on FPGA and the condition of interlock triggering can be changed from EPICS OPIs depending on the beam conditions. The use of EPICS interface can add flexibility but still satisfy fast response and reliability requirement. The design and implementation will be presented.

THP16	Remote Waveform Access Supports with EPICS for TPS and TLS Control Systems	EPICS, data-acquisition, synchrotron, Ethernet	198
	Y.-S. Cheng, K.T. Hsu, K.H. Hu, C.Y. Liao, C.Y. Wu NSRRC, Hsinchu, Taiwan
	To eliminate long distance cabling for improving signal quality, the remote waveform access supports have been developed and applied on the TPS (Taiwan Photon Source) and TLS (Taiwan Light Source) control systems. Waveforms include pulse magnets power supplies waveforms, AC waveforms of main power supplies, LLRF waveforms, beam signals, etc., and these are necessary to be monitored during routine beam operation. One is that use the EPICS-embedded data acquisition systems which are formed by the Zynq System-on-Chip architecture to capture the waveform signals; the other is that a dedicated EPICS IOC is used to communicate with the present Ethernet-based oscilloscopes to acquire each waveform data. According to specific purposes use, the different graphical applications have been developed and integrated into the existing operation interfaces. These are convenient to observe waveform status and to analyze the acquired data on the control consoles. The efforts are described at this paper.

	SuperKEKB project aims at world highest luminosity to 8x10³⁵cm^-2s^-1. To achieve the luminosity, a lot of equipment was newly constructed or upgraded. Especially, Damping Ring (DR) was newly constructed for reducing positron emittance, and was located at the middle of the injector LINAC. The DR timing system was also constructed. The synchronized timing which is generated at injector LINAC, is received at DR sub timing station and is distributed the end of some equipment, Kicker, Septum, and monitoring devices. We succeeded to generate not only synchronized timing but also beam control information such as beam gate for trigger inhibit signal and injection and extraction timing "value" via data buffer delivery. By using this method, accelerator operation became more convenient system.

	The purpose of a Low-Level Radio Frequency (LLRF) system is to control the accelerating cavity field amplitude and phase. To have better RF field stability, precise control and high noise reduction, a digital LLRF control system based on Field Programmable Gate Arrays (FPGA) was developed at NSRRC. We replaced the analog LLRF system with a digital version for the TPS booster ring at the beginning of 2018. During routine operation of the booster RF, some faults occurred when the digital LLRF operated in the energy savings mode. The performance and operational experience of the digital LLRF for the TPS booster will be presented here.

	Operating an injector of a synchrotron light source, energy efficiency is an important issue. Dipole and quadrupoles families of the booster synchrotron for Taiwan Light Source (TLS) is resonantly excited by three White circuits at 10 Hz rate. Magnet current cannot response in cycle-by-cycle basic due to resonance nature. The possibility of operation of the booster synchrotron in energy saving mode is explored. Minimizing the duration of magnet excitation without effect of the injected and extracted beam to support top-up operation for the TLS is investigated. Efforts will be presented in this report.

THP23	Further Improvements in Power Supply Controller Transient Recorders for Post-Mortem Analysis of BPM Orbit Dumps at PETRA-III	power-supply, operation, status, interface	220
	P.K. Bartkiewicz, C. Gindler, G.K. Sahoo DESY, Hamburg, Germany
	PETRA-III is a 3rd generation synchrotron light source dedicated to users with 14 beamlines beginning operations in 2010. The storage ring was modified in 2014 for an additional 12 beamlines in two extensions. It is operated with several filling modes with 100mA at electron beam energy of 6 GeV. The horizontal beam emittance is 1.30 nmrad with 1% coupling. During a user run the Machine Protection System may trigger an unscheduled beam dump if transients in the magnet power supply (PS) currents are detected which are above permissible limits. PS controllers provide transient recorder data, showing differences between current set-point and readout values in a time span of several seconds around the moment of a beam loss. We describe automatic management system handling a large number of PSs, performing automatic transient recorder data readout, storing and available for offline analysis. We discuss hardware implementation of transient recorders and its configuration software, a Java GUI application used to investigate the transient behavior of different PSs, which might have been responsible for emittance growth, orbit fluctuations, or the beam dumps seen in a post-mortem analysis.

FRCB1	Ultra Fast Data Acquisition in ELI Beamlines	laser, interface, FPGA, data-acquisition	230
	P. Bastl Institute of Physics of the ASCR, Prague, Czech Republic V. Gaman, O. Janda, P. Pivonka, B. Plötzeneder, J. Sys, J. Trdlicka ELI-BEAMS, Prague, Czech Republic
	The ELI Beamlines facility is a Petawatt laser facility in the final construction and commissioning phase in Czech Republic. In fully operation phase, four lasers will be used to control beamlines in six experimental halls. In this paper we describe Ultra fast and distributed data acquisition system as was defined in ELI Beamlines. The data acquisition system is divided into two levels: central and local level. The central level data acquisition system defines a special Tier 0 RAM buffer. This buffer is based on special multi node data acquisition server which shares memory of all its nodes into one continuous space over low latency network technologies (Mellanox Infinband/Intel OmniPath). The main role of the Tier 0 buffer is to acquire first bunch and provide load balancing of incoming data. These data comes from many sources distributed along the experimental technologies. The local data acquisition system is then responsible for connection of local detectors to central data acquisition server through ROCE interface. The connection is done directly when supported or indirectly using local data acquisition computers (for PCIe etc.).

FRCC2	Continuous Beam Scanning Intensity Control of a Medical Proton Accelerator Using a Simulink Generated FPGA Gain Scheduled Controller	proton, power-supply, cyclotron, radiation	242
	P. Fernandez Carmona, C. Bula, M. Eichin, G. Klimpki, D. Meer, V. Minnig, S. Psoroulas, D.C. Weber PSI, Villigen PSI, Switzerland
	At the Centre for Proton Therapy at the Paul Scherrer Institut we treat cancer patients using a fixed beam line and two gantries. The latter use a step-and-shoot technique to deliver dose covering the treatment volume with a grid of weighted proton bunches. Dose delivery for tumours moving under respiration (e.g. lung) is however challenging and not routinely performed because of the interplay between target and beam motions. At the Gantry 2 unit, we are implementing a novel continuous beam modulation concept called line scanning, aiming at realizing a faster dose delivery to allow for effective organ motion mitigation techniques such as rescanning and gating. The current should stabilise within 100 us, which is tough due to the non-linearity of the system and latency of the monitors. In this work we implemented a gain scheduled controller and a predictor by modelling the accelerator in Simulink and developing a controller using the frequency domain robust method. We used Mathwork’s HDL Coder functionality to generate VHDL code that was implemented in an FPGA in the gantry control system. Latency, overshoot and dosimetric performance improved considerably compared to a classic PID.

FRCC3	CERN Supervision, Control and Data Acquisition System for Radiation and Environmental Protection	radiation, monitoring, instrumentation, interface	248
	A. Ledeul, A. Savulescu, G. Segura, B. Styczen, D. Vazquez Rivera CERN, Meyrin, Switzerland
	The CERN Health, Safety and Environment Unit is mandated to provide a Radiation and Environment Supervision, Control and Data Acquisition system for all CERN accelerators, experiments as well as the environment. The operation and maintenance of the previous CERN radiation and environment supervisory systems showed some limitations in terms of flexibility and scalability. In order to face the increasing demand for radiation protection and continuously assess both conventional and radiological impacts on the environment, CERN developed and deployed a new supervisory system, called REMUS - Radiation and Environment Monitoring Unified Supervision. REMUS design and development focused on these desired features. REMUS interfaces with 75 device types, providing about 3,000 measurement channels (approximately 600, 000 tags) at the time of writing. This paper describes the architecture of the system, as well as the innovative design that was adopted in order to face the challenges of heterogeneous equipment interfacing, diversity of end users and continuous operation.

FRCC4	Maintenance and Optimization of Insertion Devices at NSLS-II Using Motion Controls	software, feedback, insertion, undulator	253
	C.A. Guerrero, J. Escallier, R.I. Farnsworth, D.A. Hidas, Y. Tian BNL, Upton, Long Island, New York, USA
	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.

!CHAOS* (Control system based on Highly Abstracted and Open Structure) is now mature and is being employed in real operational contexts. A dedicated infrastructure, recently installed at the LNF Computer Centre, houses the framework and provides control services to different LNF installations. The !CHAOS native capability of fast storage, based on the use of a non-relational database, has been finalized and tested with applications demanding high bandwidth. Thanks to its scalable design, the fast storage allows to accommodate multiple sources with sub-millisecond timing. The EU (Execution Unit) node has also been delivered and turned out to be a "Swiss Army knife" for processing both live and stored data, inserting feedbacks and in general for correlating data acquired by the CU (Control Units) nodes. A key feature of the EU is a plugin mechanism that allows to easily integrate different programming and scripting languages such as LUA, C++, Python, also exploiting the ROOT framework, the well-known scientific tool from CERN. A comprehensive description of the !CHAOS evolution, of its performances and of its use, both in scientific and industrial contexts, is presented.

D. Maier-Manojlovic
PSI, Villigen PSI, Switzerland

EtherCAT bus and interface are widely used for external module and device control in accelerator environments at PSI, ranging from modulator and undulator communication and control, over motion control, basic I/O control, all the way to Machine Protection System for the new SwissFEL accelerator. A combined EPICS/Linux driver package has been developed at PSI, to allow for simple and mostly automatic setup of various EtherCAT configurations. The driver is capable of automatic scan of the existing devices and modules, followed by self-configuration and finally autonomous operation of the EtherCAT bus real-time loop. Additionally, the driver package supports the user PLC to manipulate EtherCAT data in real time, implements fast real-time (single cycle) slave-to-slave communication (skipping EPICS layer or PLC completely), features guaranteed one-shot trigger signals otherwise not supported by EPICS and much more. All the standard EtherCAT functions are supported, including the complete reprogramming of slave configurations and configuration generation for programmable slaves, such as EL6692 and EL6695 network bridges.

BLISS is the new ESRF control system for running experiments, with full deployment aimed for the end of the EBS upgrade program in 2020. BLISS provides a global approach to run synchrotron experiments, thanks to hardware integration, Python sequences and an advanced scanning engine. As a Python package, BLISS can be easily embedded into any Python application and data management features enable online data analysis. In addition, BLISS ships with tools to enhance scientists user experience and can easily be integrated into TANGO based environments, with generic TANGO servers on top of BLISS controllers. BLISS configuration facility can be used as an alternative TANGO database. Delineating all aspects of the BLISS project from beamline device configuration up to the integrated user interface, this poster will present the technical choices that drove BLISS design and will describe the BLISS software architecture and technology stack in depth.

The industrial control systems of CERN’s experiments are undergoing major renovation since 2017 and well into CERN’s second Long Shutdown (LS2) until the end of 2019. Each detector power-supply control system runs several hundred software instances consisting of many different components in parallel on a large scale, broadly distinguishable as servers and clients. Our accumulated experience during LHC runs proves that some complex control issues are impossible to detect using stand-alone components on a small scale only. Furthermore, new components must be developed well before the electron-ics becomes available, without impact on operations. Moreover, during LS2, the improved and now widely established Open Protocol Communication Unified Ar-chitecture (OPC-UA) replaces OPC-DA as middleware protocol. For these reasons, we developed a simulation environment to emulate the real, and valuable, CAEN power-supply electronics underneath the OPC-UA serv-ers. This distributed simulation is configurable to mimic and exceed the nominal conditions during production and provides a repeatable setup for validation. This paper discusses the functionality and use of this simulation service.

Innovative Graphical User Interfaces Development: Give the Power Back to Users

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.

Fixed field alternating gradient (FFAG) accelerator complex has been operated as a proton driver for the experiment of accelerator driven system (ADS) at Institute for Integrated Radiation and Nuclear Science, Kyoto University (KURNS)*. PLC based control system has been developed and the operator interface has been connected to PLC via network. Originally, a LabVIEW based operational interface was chosen to construct the system because of its easiness. However we met an upgrade problem, and a new control system based on EPICS instead of LabVIEW was introduced in 2010. In the spring of 2018, the replacement from LabVIEW to EPICS has been almost completed except for the beam interlock system and the LINAC control system provided by LINAC production company (AccSys). Also, the EPICS archiving tool (Archiver Appliance) has been invoked and operated at the end of 2017. This Presentation reports the details of the current control system and also the upgraded GPIB control and storage system.

We report on development of the successor of the existing controller device used for the magnet power supplies in the RIKEN Radioactive Isotope Beam Factory (RIBF). The existing controller for the magnet power supplies is operated in the Versa Module European (VME) computing machines under the Experimental Physics and Industrial Control System (EPICS) framework. The present controller has been operated stably for more than 10 years, however, it is now commercially unavailable because supply of some parts has been already terminated. In 2016, we developed a successor to have the same function essentially as the existing one, but it is designed to run in control systems constructed by programmable logic controller (PLC) modules instead of the VME computing environment, in order to achieve cost reduction and functional scalability. We confirmed that the successor was successfully controlled by using a test system. And now, we are developing a control system that can flexibly add new functions through actual operation while having all the existing functions. We will introduce the successor to the new injector LINAC system this year.

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 Photo Injector Test Facility at DESY in Zeuthen (PITZ) was built to test and to optimize sources of high brightness electron beams for Free-Electron Lasers (FELs). In order to achieve high accelerating gradients and long RF pulse lengths in the RF gun cavities an extensive and safe RF conditioning is required. A State Machine based Automatic Conditioning application (SMAC) was developed to automate the RF conditioning processes, allowing for greater efficiency and performance optimization. SMAC is written in Java and uses State Chart XML (SCXML) as the finite-state machine execution environment based on Harel statecharts. It employs the Distributed Object-Oriented Control System (DOOCS) and Three-fold Integrated Networking Environment (TINE) for the communication with the control system of PITZ. The graphical user interface (GUI) is created by using the Java Swing toolkit. Communication between GUI and SXML processing layer is performed via Document Object Model (DOM) events. The SMAC application has been successfully applied to RF conditioning of several gun cavities at PITZ.

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.

In RIBF project, a superconducting linac will be implemented in order to enhance the beam energy necessary for promoting super heavy element experiment. A new 28 GHz electron resonance ion source has been installed upstream of them. Its control system will be consisted of Yokogawa FA-M3 series which is a porgrammble logic controller (PLC) with EPICS because of many achievements in case of RIBF control system. On the other hand, in the previous system with PLCs there was a disadvantage of low reliability for communications between PLC stations. Additionally, some devices (eg, oven, mivoc etc.) are changed for the generation of various kind of ions each times, therefore higher expandability is required. In the new system, we have designed the control system by utilizing star topology fieldbus for communications between the PLC stations to establish safety and expandability. In this conference, we report on the details of the system.

In the design of the ADS injector II, the RFQ cavity holds a supreme status, and the RFQ temperature and flow information are the key parameters for the cavity frequency tuning. To ensure the long-term, stable and accurate acquisition of temperature flow data is the core task of control. In this paper, the PLC temperature flow acquisition system which is based on EPICS design was described, and the EPICS driver of this PLC was developed independently. The driver uses TCP/IP connection to EPICS IOC, and the communication protocol uses the "data block overall transmission protocol", to ensure the stability of the device’s data communications. After 3 months of long-term operation inspection, this acquisition system can ensure long-term and stable acquisition of real-time temperature and flow data of the equipment, and be able to send control information to related controlled equipment. In addition, redundant PLCs and redundant IOCs were adopted in this acquisition system to make the switch to alternate channels within milliseconds once a channel fails.

Building a high power spallation target is one of the critical issues in Accelerator Driven System (ADS). The control system which was built based on the real-time distributed control software of experimental physics and industrial control system (EPICS) was attempted for the experimental target prototype. There are several sub-systems in the target system, e.g. the elevating system, the vacuum system, the heat-exchanging system. As an IOC, each sub-system was finally integrated into the control system of the target by different drivers and methods because different hardware devices were used for each sub-system. The ’SLS s7 driver’ which was devel-oped based on the Ethernet Interface was used for the communication between the Siemens PLCs and the Hu-man Machine Interface (HMI). The interfaces between Labview and EPICS were used for the NI (Nation-al Instruments) DAQs systems. In addition, the driver developed by ourselves was used for devices with serial ports, e.g. RS-232 or RS-485/422. The control system was finally proved stable and could basically meet the ele-mentary requirements of the spallation target system.

With its four accelerator facilities the Paul Scherrer Institut (PSI) has already several decades of control system Input Output Computer (IOC) experience. The technology is moving forward fast. The older hardware is becoming obsolete: it is slow, consumes too much power, does not match new computing, networking and bus technologies, and replacements can no longer be purchased as models have been discontinued. All this forces us to opt for a new "standard" IOC platform with increasing regularity. What used to be twenty years, became ten, and is now tending towards five years. Here we present past and possible future IOC platforms which we are investigating. Feedback from the conference would be highly appreciated.

Low-level radio frequency (LLRF) control systems based on µTCA standard have been developed for facilities such as compact energy recovery linac (cERL) and superconducting test facility (STF) at the High Energy Accelerator Research Organization (KEK), Japan. Three different types of boards were developed according to their different applications. Experimental physics and industrial control system (EPICS) was selected as the data communication system for all of these µTCA boards. The LLRF systems showed good performance during the beam commissioning. This paper presents the current status of the µTCA-based LLRF systems in the cERL and STF.

For a low-emittance photon light source like the Taiwan Photon Source (TPS), beam stability is a very important property for high-quality photon beams. It is, however, hard to completely remove beam disturbing effects. Therefore, a feedback/feedforward system becomes an effective tool to suppress beam motion. In this report, we discuss the performance of such a system implemented at the TPS. The component performance of the feedback system has been tested to understand its bandwidth limitations.

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.

ACOP (Advanced Component Oriented Programming) tools have been useful in control system GUI application development for some time, originally as an ActiveX component offering a transport layer and a multi-faceted chart * and then later as a suite of components in the Java world **. We now present a set of ACOP components for development in .NET. And where the emphasis in the past has been primarily on rapid application development of rich clients, this new palette of components is designed both for fully featured rich-client development in any of the .NET supported languages (C#, C++, VB, F#) as well as for fully configurable clients (with design-time browsing), where no programming on the part of the developer is necessary, and of course for any combination between these extremes. This is an important point, which will become clear when we contrast application development with ACOP. NET with other control system GUI builders such as Control System Studio and jddd. Although Visual Studio is the GUI builder of choice, we will present other available options, for example on Linux. Examples using transport plugs for TINE and STARS will be given.

STARS is an extremely simple and very flexible control software for small scale control systems with TCP/IP sockets, which is used as the beamline control system and so on at the KEK Photon Factory (KEK-PF). STARS works on various operating system and the STARS client developer can choose his or her favorite programing language. Choosing .NET is very common to develop GUI applications of beamline control at the KEK-PF. ACOP (Advanced Component Oriented Programming) is very useful for GUI development, which is developed by DESY and a .NET version of ACOP was recently developed. ACOP has a transport layer and communicate with various system through this layer. Now, we have started development of STARS transport layer of ACOP .NET and succeeded in adding very primitive functionality. The development of ACOP .NET STARS transport layer is still ongoing.

DESY, Hamburg, Germany

Web2cHMI is multi-modal human-machine interface which seamlessly incorporates actions based on various interface modalities in a single API, including finger, hand and head gestures as well as spoken commands. The set of native gestures provided by off-the-shelf 2D- or 3D-interface devices such as the Myo gesture control armband can be enriched or extended by additional custom gestures. This paper discusses a particular method and its implementation in recognizing different finger, hand and head movements using supervised machine learning algorithms including a non-linear regression for feature extraction of the movement and a k-nearest neighbor method for movement classification using memorized training data. The method is 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, which can then be associated with specific user interactions.

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.

For the RAON accelerator that transport beams with high energy and power, a machine protection system (MPS) that protects each device from sudden beam loss is necessary. For this reason, we have been preparing for the development of the MPS with the start of the RAON accelerator construction. For effective MPS operation and stable accelerator operation, we divided the MPS into four subsystems: fast protection system, slow interlock system, run permit system, and post-mortem system. Among them, the FPGA-based fast protection system and the PLC-based slow interlock system have been tested by prototypes and are currently working on the mass production. The run permit system and the post-mortem system are also undergoing basic design and software development. In this paper, we will describe the progress of the MPS development through detailed hardware and software development in the RAON accelerator and explain the future plans.

Insertion devices (ID) are essential components in third-generation synchrotron light sources, which can produce highly-brilliant, collimated and quasi-monochromatic radiation over a broad energy range for experiments. Reliable operation of the insertion devices is important to users of beamlines. The most unpredictable fault is due to a soft error in optical absolute encoders due to radiation. There are several solutions to avoid such faults, e.g. by increasing the distance of the encoder from the beam, by a lead shield cover and finally by adopting an auxiliary position sensing devices to help recovery from a fault. Efforts to improve operational reliability of the TPS ID controls will be discussed.

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.

IFMIF (International Fusion Materials Irradiation Facility) Prototype Accelerator (LIPAc) has been developed, which is designed to produce a deuteron CW beam with a current of 125 mA at 9 MeV. After the injector commissioning, the LIPAc is entering in the second commissioning phase in which RFQ, MEBT, RF Power System and Beam Instrumentation (BI) systems have been integrated. The LCSs of LIPAc have been developed by European Home Team (EU-HT) and delivered with its subsystems; the CCS, including personnel and machine protection, timing, archiving and alarming, by Japanese Home Team (JA-HT). These have been implemented on the EPICS platform to mitigate the risk of incompatibility in the integration, which JA-HT and EU-HT are jointly carrying out to control the whole accelerator. In the CCS, some interlocks associated with measurement systems–chopper interlock, protection of BI systems, etc.–are implemented on FPGA and the condition of interlock triggering can be changed from EPICS OPIs depending on the beam conditions. The use of EPICS interface can add flexibility but still satisfy fast response and reliability requirement. The design and implementation will be presented.

To eliminate long distance cabling for improving signal quality, the remote waveform access supports have been developed and applied on the TPS (Taiwan Photon Source) and TLS (Taiwan Light Source) control systems. Waveforms include pulse magnets power supplies waveforms, AC waveforms of main power supplies, LLRF waveforms, beam signals, etc., and these are necessary to be monitored during routine beam operation. One is that use the EPICS-embedded data acquisition systems which are formed by the Zynq System-on-Chip architecture to capture the waveform signals; the other is that a dedicated EPICS IOC is used to communicate with the present Ethernet-based oscilloscopes to acquire each waveform data. According to specific purposes use, the different graphical applications have been developed and integrated into the existing operation interfaces. These are convenient to observe waveform status and to analyze the acquired data on the control consoles. The efforts are described at this paper.

SuperKEKB project aims at world highest luminosity to 8x10³⁵cm^-2s^-1. To achieve the luminosity, a lot of equipment was newly constructed or upgraded. Especially, Damping Ring (DR) was newly constructed for reducing positron emittance, and was located at the middle of the injector LINAC. The DR timing system was also constructed. The synchronized timing which is generated at injector LINAC, is received at DR sub timing station and is distributed the end of some equipment, Kicker, Septum, and monitoring devices. We succeeded to generate not only synchronized timing but also beam control information such as beam gate for trigger inhibit signal and injection and extraction timing "value" via data buffer delivery. By using this method, accelerator operation became more convenient system.

The purpose of a Low-Level Radio Frequency (LLRF) system is to control the accelerating cavity field amplitude and phase. To have better RF field stability, precise control and high noise reduction, a digital LLRF control system based on Field Programmable Gate Arrays (FPGA) was developed at NSRRC. We replaced the analog LLRF system with a digital version for the TPS booster ring at the beginning of 2018. During routine operation of the booster RF, some faults occurred when the digital LLRF operated in the energy savings mode. The performance and operational experience of the digital LLRF for the TPS booster will be presented here.

Operating an injector of a synchrotron light source, energy efficiency is an important issue. Dipole and quadrupoles families of the booster synchrotron for Taiwan Light Source (TLS) is resonantly excited by three White circuits at 10 Hz rate. Magnet current cannot response in cycle-by-cycle basic due to resonance nature. The possibility of operation of the booster synchrotron in energy saving mode is explored. Minimizing the duration of magnet excitation without effect of the injected and extracted beam to support top-up operation for the TLS is investigated. Efforts will be presented in this report.

Number of pulsed signals is counted and stored in a cell of memory-buffer, then, each external trigger (25 Hz) shifts the pointer to the cell. The buffer size (192) is designed to store one machine-cycle (2480 ms or 5200 ms in J-PARC). Demonstrative measurements using a prototype module are reported. In addition, scheme to detect miss-trigger events are discussed.

PETRA-III is a 3rd generation synchrotron light source dedicated to users with 14 beamlines beginning operations in 2010. The storage ring was modified in 2014 for an additional 12 beamlines in two extensions. It is operated with several filling modes with 100mA at electron beam energy of 6 GeV. The horizontal beam emittance is 1.30 nmrad with 1% coupling. During a user run the Machine Protection System may trigger an unscheduled beam dump if transients in the magnet power supply (PS) currents are detected which are above permissible limits. PS controllers provide transient recorder data, showing differences between current set-point and readout values in a time span of several seconds around the moment of a beam loss. We describe automatic management system handling a large number of PSs, performing automatic transient recorder data readout, storing and available for offline analysis. We discuss hardware implementation of transient recorders and its configuration software, a Java GUI application used to investigate the transient behavior of different PSs, which might have been responsible for emittance growth, orbit fluctuations, or the beam dumps seen in a post-mortem analysis.

The ELI Beamlines facility is a Petawatt laser facility in the final construction and commissioning phase in Czech Republic. In fully operation phase, four lasers will be used to control beamlines in six experimental halls. In this paper we describe Ultra fast and distributed data acquisition system as was defined in ELI Beamlines. The data acquisition system is divided into two levels: central and local level. The central level data acquisition system defines a special Tier 0 RAM buffer. This buffer is based on special multi node data acquisition server which shares memory of all its nodes into one continuous space over low latency network technologies (Mellanox Infinband/Intel OmniPath). The main role of the Tier 0 buffer is to acquire first bunch and provide load balancing of incoming data. These data comes from many sources distributed along the experimental technologies. The local data acquisition system is then responsible for connection of local detectors to central data acquisition server through ROCE interface. The connection is done directly when supported or indirectly using local data acquisition computers (for PCIe etc.).

At the Centre for Proton Therapy at the Paul Scherrer Institut we treat cancer patients using a fixed beam line and two gantries. The latter use a step-and-shoot technique to deliver dose covering the treatment volume with a grid of weighted proton bunches. Dose delivery for tumours moving under respiration (e.g. lung) is however challenging and not routinely performed because of the interplay between target and beam motions. At the Gantry 2 unit, we are implementing a novel continuous beam modulation concept called line scanning, aiming at realizing a faster dose delivery to allow for effective organ motion mitigation techniques such as rescanning and gating. The current should stabilise within 100 us, which is tough due to the non-linearity of the system and latency of the monitors. In this work we implemented a gain scheduled controller and a predictor by modelling the accelerator in Simulink and developing a controller using the frequency domain robust method. We used Mathwork’s HDL Coder functionality to generate VHDL code that was implemented in an FPGA in the gantry control system. Latency, overshoot and dosimetric performance improved considerably compared to a classic PID.

The CERN Health, Safety and Environment Unit is mandated to provide a Radiation and Environment Supervision, Control and Data Acquisition system for all CERN accelerators, experiments as well as the environment. The operation and maintenance of the previous CERN radiation and environment supervisory systems showed some limitations in terms of flexibility and scalability. In order to face the increasing demand for radiation protection and continuously assess both conventional and radiological impacts on the environment, CERN developed and deployed a new supervisory system, called REMUS - Radiation and Environment Monitoring Unified Supervision. REMUS design and development focused on these desired features. REMUS interfaces with 75 device types, providing about 3,000 measurement channels (approximately 600, 000 tags) at the time of writing. This paper describes the architecture of the system, as well as the innovative design that was adopted in order to face the challenges of heterogeneous equipment interfacing, diversity of end users and continuous operation.

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.
