	The Experimental Physics and Industrial Control System (EPICS), is an open-source software framework for high-performance distributed control, and is at the heart of many of the world’s large accelerators and telescopes. Recently, EPICS has undergone a major revision, with the aim of better computing supporting for the next generation of machines and analytical tools. Many new data types, such as matrices, tables, images, and statistical descriptions, plus users’ own data types, now supplement the simple scalar and waveform types of the former EPICS. New computational architectures for scientific computing have been added for high-performance data processing services and pipelining. Python and Java bindings have enabled powerful new user interfaces. The result has been that controls are now being integrated with modelling and simulation, machine learning, enterprise databases, and experiment DAQs. We introduce this new EPICS (version 7) from the perspective of accelerator physics and review early adoption cases in accelerators around the world.

WEPGW003	High-Level Applications for the Sirius Accelerator Control System	controls, MMI, linac, GUI	2462
	X.R. Resende, L. Liu, A.C.S. Oliveira, F.H. de Sá, G.L. do Prado LNLS, Campinas, Brazil
	Sirius is the new 3 GeV low-emittance Brazilian Synchrotron Light source under installation and commissioning at LNLS. The machine control system is based on EPICS and when the installation is complete it should have a few hundred thousand process variables in use. For flexible integration and intuitive control of such sizable system a considerable number of high-level applications, input/output controllers and graphical user interfaces have been developed, mostly in Python, using a variety of libraries, such as PyEpics, PCASPy and PyDM. Common support service applications (Archiver Appliance, Olog, Apache server, a mongoDB-based configuration server, etc) are used. Matlab Middle Layer is also an available option to control EPICS applications. Currently system integration tests are being performed concomitant with initial phases of accelerator commissioning and installation. A set of functionalities is already available: Linac’s control; timing subsystem control; machine snapshots; optics measurements and correction; magnets settings and cycling; Booster orbit acquisition and correction, and so on. From the experience so far, subsystems communications have worked satisfactorily but there has been a few unexpected component performance. In this paper we discuss this experience and descrive the libraries and packages used in high-level control system , as well as the difficulties faced to implement and to operate them.

WEPGW007	Progress of the Machine Control Upgrade at COSY/JüLICH	controls, operation, experiment, quadrupole	2473
	V. Kamerdzhiev, I. Bekman, C. Böhme, R. Gebel, B. Lorentz, P. Niedermayer, M. Simon, M. Thelen FZJ, Jülich, Germany R. Modic, ’. Oven Cosylab, Ljubljana, Slovenia
	The Cooler Synchrotron COSY operated at the Research Center Jülich is undergoing staged machine control upgrades driven by the requirements of the JEDI (Jülich Electric Dipole moment Investigations) collaboration. The upgrades aim towards better beam control e.g. beam orbit, tune, and chromaticity control improvements. A better orbit control was achieved through the upgrade of BPM electronics and migration from initial Tcl/Tk based control system to Control System Studio (CSS) utilizing EPICS. Currently, a design for improved beam tune control is in development. The main part of work is the transition towards a faster and less restrictive magnet control. It further includes improved tune measurement tools as well as the migration of control for quadrupole magnets to EPICS. Ultimately the control of all systems should be centralized around EPICS to enable ease of operation, automation, setup of services, etc. The decision path, technical details of the upgrade and performance of the upgraded sub-systems are presented. We also showcase how the COSY team’s physics and research goals are complemented by Cosylab’s technical design and implementation to form a synergetic collaboration.

WEPGW071	Evaluation of a New 500 MHz Digitizer at Elettra and Fermi	pick-up, interface, insertion, storage-ring	2635
	P. Leban, M. Žnidarčič I-Tech, Solkan, Slovenia S. Bassanese, G. Brajnik, R. De Monte Elettra-Sincrotrone Trieste S.C.p.A., Basovizza, Italy
	A new digitizer was evaluated in ELETTRA storage ring and FERMI linear accelerator. The A/D conversion is done with 14-bits at 500 MS/s. The sampling clock is hard-locked to the Master Oscillator and has a jitter of a maximum 10 ps. The AC coupled version has an analog bandwidth up to 2 GHz and was used to measure the fill pattern. The bunch flat-top is very narrow (10^-15 ps). To reach better stability, various external filtering components were used. Bunch-by-bunch beam position was calculated offline and compared to a standard BPM electronics. The DC coupled version was used to sample pulses from the fast current transformer at FERMI. A software interface can configure data acquisition length and fill buffer segments with pre-defined number of triggers. Native TANGO and EPICS interfaces allow for fast integration with CSS and other display tools.

WEPGW073	Control System for Lasers at Hilase	laser, controls, software, PLC	2641
	J. Horáček, T. Mocek, M. Rehakova HiLASE Centre, Institute of Physics ASCR, v.v.i., Dolní Bře’any, Czech Republic R. Modic, J. Podlipnik, M. Pogacnik Cosy lab, Ljubljana, Slovenia
	We present the current state of the HiLASE Centre control system developed in cooperation with Cosylab. The aim of the development is to build a control system which would be in charge of the operation of kW-class in-house-developed laser beamlines. These beamlines deliver picosecond pulses with repetition rates between 1 kHz and 1 MHz and high-energy nanosecond pulses at 10 Hz. A generic control system architecture is presented, which can either support full-size development lasers or compact industrial versions. The EPICS control system work focuses on image acquisition and processing, vacuum control, provision of timing, archiving and user interfaces. HiLASE provides high-level requirements, Cosylab complements them, provides the design of the solution and implementation. Delivery is performed during on-site visits where a test plan is executed for acceptance. This approach relieves HiLASE of the need to hire and manage their own team while retaining full control over the functionality through requirements and acceptance approval. Cosylab complements HiLASE with self-managed teams that deliver to specification.

WEPGW074	MYRRHA DAQ Development	controls, GUI, LabView, software	2645
	R. Modic Cosy lab, Ljubljana, Slovenia P. Della Faille, D. Vandeplassche SCK•CEN, Mol, Belgium P. Mekuc Cosylab, Ljubljana, Slovenia
	An approach to a generic Data Acquisition (DAQ) solution for the MYRRHA test stand at Louvain-la-Neuve (Belgium) will be described in this paper. Need for better sampling performance, signal quality, arbitrary processing and storage of measurements was a motivation for this work. A full integration of the DAQ system in the global EPICS control environment was a strong requirement. An intermediate DAQ platform was put in place to satisfy the control and experiment needs. The NI PXI platform is selected to minimize integration and development effort. NI LabVIEW is used to create a generic DAQ application. CALab library supported by BESSY is used to connect LabVIEW and EPICS. CSS GUI provides the user with the necessary control, visualization and configuration capability. The technical and organizational approach to the collaboration will be detailed in the paper. Necessary customizations of CSS and CALab and experience on using NI PXI for DAQ platform will be explained.

WEPGW079	A Channel Access Software Platform for Beam Dynamics Applications in Scripting Languages	interface, controls, software, MMI	2661
	J.T.M. Chrin, M. Aiba, J. Snuverink PSI, Villigen PSI, Switzerland
	To facilitate the seamless integration of EPICS (Experimental Physics and Industrial Control System) into high-level applications in particle accelerators, a dedicated modern C++ Channel Access Interface (CAFE) library* provides a comprehensive and user-friendly interface to the underlying control system. Functionality is provided for synchronous and asynchronous interaction of single and composite groups of channels, coupled with an abstract layer tailored towards beam dynamics applications and complex modelling of virtual accelerators. Equivalent consumable solutions in scripting and domain-specific languages can then be accelerated by providing bindings to the relevant methods of the interface platform. This is exemplified by CAFE’s extensive MATLAB interface, incarnated through a single MATLAB executable (mex) file, and a high performance Python interface written in the Cython programming language. A number of gratifying particularities specific to these language extension modules are revealed. * http://cafe.psi.ch

WEPGW085	Development of Operating Alarm System at TPS	operation, controls, vacuum, storage-ring	2684
	C.S. Huang, B.Y. Chen, C.K. Kuan, C.H. Kuo, T.Y. Lee, W.Y. Lin, S.Y. Perng, T.C. Tseng, H.S. Wang NSRRC, Hsinchu, Taiwan
	The Taiwan Photon Source (TPS) has many subsystems which includes magnet, power supply, vacuum, RF system, insertion device, control system, etc. Therefore, the operational and system check procedures are complex. In this paper, we summarize the routine operational procedures and propose an integrated operational alarm system that gathers machine information and sets high/low warning and fault limits for various signals which can help operators to quickly identify abnormal subsystems, thereby reducing machinery down time. The alarm system also has a wide range of applications, such as the event recording that helps the analysis after event. This new alarm system interface clearly indicates the machine status and improves operational efficiency.

	S. Chen, R.B. Hogan, A. Michalczyk, A.C. Starritt, Y.E. Tan AS - ANSTO, Clayton, Australia
	The Enhanced Orbit Diagnostic (EOD) features will be an expansion to the existing Fast Orbit Feedback (FOFB) system that is currently in operation. The new system will add the capability of online cor-rector-to-position response matrix calculation; this will significantly reduce the required measurement time. The new features will allow the injection of PRBS noise or sinusoidal signals into correctors, to characterise and monitor the FOFB system’s parameters and performance and track it over time. The system will be built based on a Xilinx ZYNQ Sys-tem-on-Module (SOM) mounted on an in-house designed motherboard to which the existing FOFB daughter board is plugged into.

	Funding: US Department of Energy DE-SC 0013571 Algorithmic control of accelerators is an active area of research that promises significant improvements in machine performance. To facilitate rapid algorithm prototyping, we have developed a generic interface between accelerator controls, beam physics modelling software and modern scripting languages. The work-flow of a project using this interface begins with testing algorithms of choice offline in simulation. After off-line testing, the same code can be deployed on real machines via the Experimental Physics and Industrial Control System (EPICS) API. We include noise in our simulations in order to mimic realistic accelerator behaviour and to evaluate robustness of algorithms to experimental uncertainties and long-term drifts. The results of test cases of using this framework are presented, including emittance tuning of the Cornell Electron Storage Ring (CESR), correction of diurnal drift in CESR steering and orbit correction on CESR and the Cornell-BNL ERL Test Accelerator (CBETA).

	Funding: The Australian Federal Government Superscience/EIF funding under the NCRIS mechanism. An 8 Tesla superconducting solenoid was commissioned at The Australian National University to make precision measurements of fusion cross-sections. Forces between the solenoid and the iron yoke that houses it must always be maintained within safe limits and precision location of the solenoid coil is necessary to achieve this. Thermal contraction of components can impact the locating structure of the solenoid coil, leading to unsafe forces. Improvements to this structure allowed successful completion of the first fusion measurements with the 8T solenoidal separator, and demonstrated that it is now ready for a program of fusion measurements.

	T. Šuštar Cosylab, Villigen, Switzerland P. Bucher, G. Theidel PSI, Villigen PSI, Switzerland R. Modic Cosy lab, Ljubljana, Slovenia
	SwissFEL, the new Free-Electron Laser facility is a 740 m long accelerator with the goal of providing pulses of light between 6 and 30 fs long at a wavelength of 1 to 7 Å at 100 Hz. To support shot-to-shot photon diagnostic and link the measurements to other measurements along the machine that belong to the same machine pulse, a new triggering and data acquisition system was developed. A new protocol was introduced which allows deterministic triggering, configuration and data transfer via one full-duplex optical connection. The measurement data is stamped with an unique pulse identifier, delivered from the SwisFEL Timing System*. A readout and control interface was developed to support data delivery to the Data Acquisition Dispatching Layer and for controlling the system. * Milne, et al., SwissFEL: The Swiss X-Ray Free-Electron Laser, Appl.

THPTS070	Diagnostic Tool For CompactPCI Crates	controls, status, diagnostics, network	4275
	H.Z. Chen, C.H. Chen, Y.-S. Cheng, K.T. Hsu, K.H. Hu, C.Y. Liao, C.Y. Wu NSRRC, Hsinchu, Taiwan
	On the control system hardware platform for the Taiwan Photon Source (TPS) more than half use CompactPCI crates. If a crate malfunctions, the internal crate card will not operate properly affecting accelerator operation. If the crate, however, could provide instant remote operational information, an opportunity exists to maintain or replace it in advance. Therefore, a diagnostic tool was developed to analyse and diagnose the condition of the crates. When abnormal operations occur, an alarm can be issued for early inspection and maintenance. This way it is possible to prevent the EPICS IOC from crashing by CompactPCI crates, which improves the reliability of accelerator operation.

The Experimental Physics and Industrial Control System (EPICS), is an open-source software framework for high-performance distributed control, and is at the heart of many of the world’s large accelerators and telescopes. Recently, EPICS has undergone a major revision, with the aim of better computing supporting for the next generation of machines and analytical tools. Many new data types, such as matrices, tables, images, and statistical descriptions, plus users’ own data types, now supplement the simple scalar and waveform types of the former EPICS. New computational architectures for scientific computing have been added for high-performance data processing services and pipelining. Python and Java bindings have enabled powerful new user interfaces. The result has been that controls are now being integrated with modelling and simulation, machine learning, enterprise databases, and experiment DAQs. We introduce this new EPICS (version 7) from the perspective of accelerator physics and review early adoption cases in accelerators around the world.

Sirius is the new 3 GeV low-emittance Brazilian Synchrotron Light source under installation and commissioning at LNLS. The machine control system is based on EPICS and when the installation is complete it should have a few hundred thousand process variables in use. For flexible integration and intuitive control of such sizable system a considerable number of high-level applications, input/output controllers and graphical user interfaces have been developed, mostly in Python, using a variety of libraries, such as PyEpics, PCASPy and PyDM. Common support service applications (Archiver Appliance, Olog, Apache server, a mongoDB-based configuration server, etc) are used. Matlab Middle Layer is also an available option to control EPICS applications. Currently system integration tests are being performed concomitant with initial phases of accelerator commissioning and installation. A set of functionalities is already available: Linac’s control; timing subsystem control; machine snapshots; optics measurements and correction; magnets settings and cycling; Booster orbit acquisition and correction, and so on. From the experience so far, subsystems communications have worked satisfactorily but there has been a few unexpected component performance. In this paper we discuss this experience and descrive the libraries and packages used in high-level control system , as well as the difficulties faced to implement and to operate them.

The Cooler Synchrotron COSY operated at the Research Center Jülich is undergoing staged machine control upgrades driven by the requirements of the JEDI (Jülich Electric Dipole moment Investigations) collaboration. The upgrades aim towards better beam control e.g. beam orbit, tune, and chromaticity control improvements. A better orbit control was achieved through the upgrade of BPM electronics and migration from initial Tcl/Tk based control system to Control System Studio (CSS) utilizing EPICS. Currently, a design for improved beam tune control is in development. The main part of work is the transition towards a faster and less restrictive magnet control. It further includes improved tune measurement tools as well as the migration of control for quadrupole magnets to EPICS. Ultimately the control of all systems should be centralized around EPICS to enable ease of operation, automation, setup of services, etc. The decision path, technical details of the upgrade and performance of the upgraded sub-systems are presented. We also showcase how the COSY team’s physics and research goals are complemented by Cosylab’s technical design and implementation to form a synergetic collaboration.

A new digitizer was evaluated in ELETTRA storage ring and FERMI linear accelerator. The A/D conversion is done with 14-bits at 500 MS/s. The sampling clock is hard-locked to the Master Oscillator and has a jitter of a maximum 10 ps. The AC coupled version has an analog bandwidth up to 2 GHz and was used to measure the fill pattern. The bunch flat-top is very narrow (10^-15 ps). To reach better stability, various external filtering components were used. Bunch-by-bunch beam position was calculated offline and compared to a standard BPM electronics. The DC coupled version was used to sample pulses from the fast current transformer at FERMI. A software interface can configure data acquisition length and fill buffer segments with pre-defined number of triggers. Native TANGO and EPICS interfaces allow for fast integration with CSS and other display tools.

We present the current state of the HiLASE Centre control system developed in cooperation with Cosylab. The aim of the development is to build a control system which would be in charge of the operation of kW-class in-house-developed laser beamlines. These beamlines deliver picosecond pulses with repetition rates between 1 kHz and 1 MHz and high-energy nanosecond pulses at 10 Hz. A generic control system architecture is presented, which can either support full-size development lasers or compact industrial versions. The EPICS control system work focuses on image acquisition and processing, vacuum control, provision of timing, archiving and user interfaces. HiLASE provides high-level requirements, Cosylab complements them, provides the design of the solution and implementation. Delivery is performed during on-site visits where a test plan is executed for acceptance. This approach relieves HiLASE of the need to hire and manage their own team while retaining full control over the functionality through requirements and acceptance approval. Cosylab complements HiLASE with self-managed teams that deliver to specification.

An approach to a generic Data Acquisition (DAQ) solution for the MYRRHA test stand at Louvain-la-Neuve (Belgium) will be described in this paper. Need for better sampling performance, signal quality, arbitrary processing and storage of measurements was a motivation for this work. A full integration of the DAQ system in the global EPICS control environment was a strong requirement. An intermediate DAQ platform was put in place to satisfy the control and experiment needs. The NI PXI platform is selected to minimize integration and development effort. NI LabVIEW is used to create a generic DAQ application. CALab library supported by BESSY is used to connect LabVIEW and EPICS. CSS GUI provides the user with the necessary control, visualization and configuration capability. The technical and organizational approach to the collaboration will be detailed in the paper. Necessary customizations of CSS and CALab and experience on using NI PXI for DAQ platform will be explained.

2661

J.T.M. Chrin, M. Aiba, J. Snuverink
PSI, Villigen PSI, Switzerland

To facilitate the seamless integration of EPICS (Experimental Physics and Industrial Control System) into high-level applications in particle accelerators, a dedicated modern C++ Channel Access Interface (CAFE) library* provides a comprehensive and user-friendly interface to the underlying control system. Functionality is provided for synchronous and asynchronous interaction of single and composite groups of channels, coupled with an abstract layer tailored towards beam dynamics applications and complex modelling of virtual accelerators. Equivalent consumable solutions in scripting and domain-specific languages can then be accelerated by providing bindings to the relevant methods of the interface platform. This is exemplified by CAFE’s extensive MATLAB interface, incarnated through a single MATLAB executable (mex) file, and a high performance Python interface written in the Cython programming language. A number of gratifying particularities specific to these language extension modules are revealed.

The Taiwan Photon Source (TPS) has many subsystems which includes magnet, power supply, vacuum, RF system, insertion device, control system, etc. Therefore, the operational and system check procedures are complex. In this paper, we summarize the routine operational procedures and propose an integrated operational alarm system that gathers machine information and sets high/low warning and fault limits for various signals which can help operators to quickly identify abnormal subsystems, thereby reducing machinery down time. The alarm system also has a wide range of applications, such as the event recording that helps the analysis after event. This new alarm system interface clearly indicates the machine status and improves operational efficiency.

The Enhanced Orbit Diagnostic (EOD) features will be an expansion to the existing Fast Orbit Feedback (FOFB) system that is currently in operation. The new system will add the capability of online cor-rector-to-position response matrix calculation; this will significantly reduce the required measurement time. The new features will allow the injection of PRBS noise or sinusoidal signals into correctors, to characterise and monitor the FOFB system’s parameters and performance and track it over time. The system will be built based on a Xilinx ZYNQ Sys-tem-on-Module (SOM) mounted on an in-house designed motherboard to which the existing FOFB daughter board is plugged into.

The Australian Synchrotron (AS) is a 3rd generation light source which has been in operation since 2006. Measurement of the storage ring’s beam position is provided by 98 beam position monitors, and corrections can be applied using 42 horizontal and 56 vertical slow corrector magnets, and 42 horizontal and 42 vertical fast corrector magnets. This paper provides a background describing the feedback strategies adopted at the AS leading to the current integrated orbit feedback system, together with a description of the beam position analyse techniques currently in use. It will also highlight some of the issues encountered with the system and how they were overcome. The paper also describes planned improvements, including the enhanced orbit diagnostics functionality we are intending to introduce in the next 12 months.

Algorithmic control of accelerators is an active area of research that promises significant improvements in machine performance. To facilitate rapid algorithm prototyping, we have developed a generic interface between accelerator controls, beam physics modelling software and modern scripting languages. The work-flow of a project using this interface begins with testing algorithms of choice offline in simulation. After off-line testing, the same code can be deployed on real machines via the Experimental Physics and Industrial Control System (EPICS) API. We include noise in our simulations in order to mimic realistic accelerator behaviour and to evaluate robustness of algorithms to experimental uncertainties and long-term drifts. The results of test cases of using this framework are presented, including emittance tuning of the Cornell Electron Storage Ring (CESR), correction of diurnal drift in CESR steering and orbit correction on CESR and the Cornell-BNL ERL Test Accelerator (CBETA).

An 8 Tesla superconducting solenoid was commissioned at The Australian National University to make precision measurements of fusion cross-sections. Forces between the solenoid and the iron yoke that houses it must always be maintained within safe limits and precision location of the solenoid coil is necessary to achieve this. Thermal contraction of components can impact the locating structure of the solenoid coil, leading to unsafe forces. Improvements to this structure allowed successful completion of the first fusion measurements with the 8T solenoidal separator, and demonstrated that it is now ready for a program of fusion measurements.

SwissFEL, the new Free-Electron Laser facility is a 740 m long accelerator with the goal of providing pulses of light between 6 and 30 fs long at a wavelength of 1 to 7 Å at 100 Hz*. To support shot-to-shot photon diagnostic* and link the measurements to other measurements along the machine that belong to the same machine pulse, a new triggering and data acquisition system was developed. A new protocol was introduced which allows deterministic triggering, configuration and data transfer via one full-duplex optical connection. The measurement data is stamped with an unique pulse identifier, delivered from the SwisFEL Timing System**. A readout and control interface was developed to support data delivery to the Data Acquisition Dispatching Layer* and for controlling the system.

On the control system hardware platform for the Taiwan Photon Source (TPS) more than half use CompactPCI crates. If a crate malfunctions, the internal crate card will not operate properly affecting accelerator operation. If the crate, however, could provide instant remote operational information, an opportunity exists to maintain or replace it in advance. Therefore, a diagnostic tool was developed to analyse and diagnose the condition of the crates. When abnormal operations occur, an alarm can be issued for early inspection and maintenance. This way it is possible to prevent the EPICS IOC from crashing by CompactPCI crates, which improves the reliability of accelerator operation. A detailed system architecture, implementation and progress will be discussed in this report.
