	The SwissFEL is a new free electron laser facility at the Paul Scherrer Institute (PSI) in Switzerland. Commissioning started in 2016 and resulted in first lasing in December 2016 (albeit not on the design energy). In 2017, the commissioning continued and will result in the first pilot experiments at the end of the year. The close interaction of experiment and accelerator components as well as the pulsed electron beam required a well thought out integration of the control system including some new concepts and layouts. This paper presents the current status of the control system together with some lessons learned.

MODPL07	How Low-Cost Devices Can Help on the Way to ALICE Upgrade	ion, experiment, controls, monitoring	114
	O. Pinazza INFN-Bologna, Bologna, Italy A. Augustinus, P.M. Bond, P.Ch. Chochula, A.N. Kurepin, M. Lechman, J.L. LÃ¥ng, O. Pinazza CERN, Geneva, Switzerland A.N. Kurepin RAS/INR, Moscow, Russia
	The ambitious upgrade plan of the ALICE experiment expects a complete redesign of its data flow after the LHC shutdown scheduled for 2019, for which new electronics modules are being developed in the collaborating institutes. Access to prototypes is at present very limited and full scale prototypes are expected only close to the installation date. To overcome the lack of realistic HW, the ALICE DCS team built small-scale prototypes based on low-cost commercial components (Arduino, Raspberry PI), equipped with environmental sensors, and installed in the experiment areas around and inside the ALICE detector. Communication and control software was developed, based on the architecture proposed for the future detectors, including CERN JCOP FW and ETM WINCC OA. Data provided by the prototypes has been recorded for several months, in presence of beam and magnetic field. The challenge of the harsh environment revealed some insurmountable weaknesses, thus excluding this class of devices from usage in a production setup. They did prove, however, to be robust enough for test purposes, and are still a realistic test-bed for developers while the production of final electronics is continuing.

TUCPA05	Laser Damage Image Pre-processing Based on Total Variation	ion, optics, laser, site	272
	J. Luo, Z. Ni, X. Xie, X. Zhou CAEP, Sichuan, People's Republic of China
	The inspection and tracking of laser-induced damages of optics play a significant role in high-power laser systems. Laser-induced defects or flaws on the surfaces of optics are presented in images acquired by specific charge coupled devices (CCDs), hence the identification of defects from laser damage images is essential. Despite a great effort we have made to improve the imaging results, the defect identification is a challenging task. The proposed research focuses on the pre-processing of laser damage images, which assists identifying optic defects. We formulate the image pre-processing as a total variation (TV) based image reconstruction problem, and further develop an alternating direction method of multipliers (ADMM) algorithm to solve it. The use of TV regularization makes the pre-processed image sharper by preserving the edges or boundaries more accurately. Experimental results demonstrate the effectiveness of this method.

TUMPL02	Streamlining Support and Development Activities Across the Distinct Support Groups of the ALBA Synchrotron with the Implementation of a New Service Management System	ion, controls, software, project-management	298
	M. Martin, A. Burgos, C. Colldelram, G. Cuní, D. Fernández-Carreiras, E. Fraga, G. García López, O. Matilla, A. Pérez Font, D. Salvat ALBA-CELLS Synchrotron, Cerdanyola del Vallès, Spain
	The MIS section in the Computing division at ALBA Synchrotron designs and supports management information systems. This paper describes the streamlining of the work of 12 support groups into a single customer portal and issue management system. Prior to the change, ALBA was using five different ticket systems. To improve coordination, we searched tools able to support ITIL Service Management, as well as PRINCE2 and Agile Project Management. Within market solutions, JIRA, with its agile boards, calendars, SLAs and service desks, was the only solution with a seamless integration of both. Support teams took the opportunity to redesign their service portfolio and management processes. Through the UX design, JIRA has proved to be a flexible solution to customize forms, workflows, permissions and notifications on the fly, creating a virtuous cycle of rapid improvements, a rewarding co-design experience which results in highly fitting solutions and fast adoption. Team, project and service managers now use a single system to track requests in a timely manner, view trends, and get a consolidated view of efforts invested in the different beamlines and accelerators.

TUMPA07	Advances in Automatic Performance Optimization at FERMI	ion, FEL, laser, experiment	352
	G. Gaio, N. Bruchon, M. Lonza Elettra-Sincrotrone Trieste S.C.p.A., Basovizza, Italy L. Saule University of Trieste, Trieste, Italy
	Despite the large number of feedback loops running simultaneously at the FERMI Free Electron Laser (FEL), they are not sufficient to keep the optimal machine working point in the long term, in particular when the machine is tuned in such a way to be more sensitive to drifts of the critical parameters. In order to guarantee the best machine performance, a novel software application which minimizes the shot to shot correlation between these critical parameters and the FEL radiation has been implemented. This application, which keeps spatially and temporally aligned the seed laser and the electron beam, contrary to many algorithms that inject noise in the system to be optimized, run transparently during the experiment beam times. In this paper we will also present a newly developed method to calculate a beam 'quality factor' starting from the images provided by a photon spectrometer, which tries to mimic the evaluation of machine physicists, as well as the results obtained using two model-less algorithms to optimize the FEL performance through maximization of the quality factor.

TUPHA001	Research on Fault Diagnosis of Power Supply Control System on BEPCII	ion, power-supply, controls, interface	361
	D. Wang, J. Liu, X.L. Wang IHEP, Beijing, People's Republic of China
	The reliable and stable operation of the accelerator is the premise and foundation of physics experiments. For example, in the BEPCII, the fault of the magnet power supply front-end electronics devices may cause accelerator energy instability and even lead to beam loss. Therefore, it is very necessary to diagnose and locate the device fault accurately and rapidly, that will induce the high cost of the accelerator operation. Faults diagnosis can not only improve the safety and reliability of the equipment, but also effectively reduce the equipment's cycle costing. The multi-signal flow model proposed by Pattipati K.R is considered as the preferred method of industrial equipment faults detection. However, there are still some problems about fault probability conflict in the processing of correlation matrix diagnosis due to the hierarchical nature of multi-signal flow modeling. Thus we develop the fault diagnosis strategy based on the important prior knowledge of the fault. This method is applied to the front-end electronic devices of BEPCII magnet power supply control system and improves the fault diagnosis and analysis ability of magnet power supply control system.

	Novosibirsk Free electron Laser (FEL) based on multi-turn energy recovery linac is the source of coherent radiation with ability of wavelength tuning. It involves one single-turn and one 4-turn microtron-recuperator, which are have general injection channel and acceleration section. There are three different free electron lasers, mounted on different tracks of these accelerators, and operating on different electron beam energy and have different wavelength range and power of generated radiation. Whole FEL facility is a complex physics installation, controlled by large amount of equipment of different types. Therefore, for effective control and monitor of FEL operation state and its parameters, the particularized control system was developed. In this paper the architecture, hardware, software compound parts of this control system are considered. Also main abilities, characteristics of this system and examples of its usage are presented.

	In NSC KIPT, Kharkov, Ukraine the state of art nuclear facility Neutron Source on the base of subcritical assembly driven with 100 MeV/100 kW electron linear accelerator has been build. The electron beam generates neutrons during bombarding the tungsten or uranium target. The subcritical assembly of low enrichment uranium is used to multiply the initial neutrons due to fission of the uranium nuclei. The facility is the first world facility of such kind. It is supposed that maximal value of multiplying neutron factor in the source will be equal to 0.95. So, the neutron flux will be increased as much as 50 times. Because of sub-criticality the facility eliminates the possibility to produce the self-sustained chain reaction. Now the Neutron source is under commissioning. In the report the facility and its control system current status is presented.

	Funding: The work described was funded by the U.S. Department of Energy, Office of Science via the Isotope Development and Production for Research and Applications subprogram in the Office of Nuclear Physics. Isotopes produced at Los Alamos National Laboratory (LANL) are saving lives, advancing cutting-edge research, and helping to address national security questions. For the past two years LANL's Accelerator Operations & Technology Division has executed a $6.4M improvement project for the Isotope Production Facility. The goals are to reduce the programmatic risk and enhance facility reliability while at the same time pursuing opportunities to increase general isotope production capacity. This has led to some exciting innovations. In this paper we will discuss the engineering designs for our new collimator, which is both adjustable and 'active' (i.e. equipped with beam current and temperature measurements), as well as our upgraded beam raster system and new beam diagnostics capabilities. We will also report on results obtained and lessons learned from the commissioning phase and initial production run. LA-UR-17-22778

	Synchrotron facilities provides short, regular and high frequency flashes of light. These pulses are used by the scientific community for time resolved experiments. To improve the time resolution, demands for always shorter X-ray pulses are growing. To achieve this goal, Synchrotron SOLEIL and MAX IV laboratory have developed special operating modes such as low-alpha and femtoslicing, as well as a single pass linear accelerator. For the most demanding experiments, the synchronization between short light pulses and pump-probe devices requires sub-picoseconds delay adjustment. The TimIQ system has been developed for that purpose. It is a joint development between Synchrotron Soleil and MAX IV Laboratory. It is aimed to be used on three beamlines at Soleil and one at MAX IV. Based on IQ modulation technics, it allows shifting a radio frequency clock by steps of #100 fs. This paper is a description of this system and of its performances.

TUPHA118	Correction of 10 Hz Orbit Distortion From Diamond's I10 Fast Switching Chicane	ion, controls, power-supply, polarization	682
	M.J. Furseman, C.P. Bailey, S. Gayadeen, G. Rehm, W.A.H. Rogers DLS, Oxfordshire, United Kingdom
	The I10 beamline at Diamond Light Source is configured to study circular dichroism. To increase signal to noise ratio between the two beam polarisations and increase temporal resolution the beamline is fed by two separate IDs that are typically configured with opposite handed polarisations. A chicane of steering magnets with programmable power supplies is used to provide 10 Hz switching between the two photon beams by producing a dynamic closed bump that alternates the on-axis trajectory of the electron beam between the two IDs. In order to maintain the closed bump and make the switching transparent to the rest of the photon beamlines the phase and amplitude of the sine functions applied to the chicane magnets must be exactly correct. In this paper the linear scheme that was used to correct the residual 10 Hz orbit distortion is presented. Future work that uses the fully programmable nature of the magnet power supply controllers to correct high order distortions is also discussed.

TUPHA125	The Bunch Arrival Time Monitor at FLASH and European XFEL	ion, laser, controls, FEL	701
	M. Viti, M.K. Czwalinna, H. Dinter, C. Gerth, K.P. Przygoda, R. Rybaniec, H. Schlarb DESY, Hamburg, Germany
	In modern free electron laser facilities like FLASH I/II and European XFEL at DESY a high resolution intra bunch train arrival time measurement is mandatory, providing a crucial information for the beam based feedback system. For this purpose a Bunch Arrival Time Monitor (BAM) was developed, based on an electro-optical scheme where an ultra-short pulsed laser is employed. A BAM is composed of several subsystems, including stepper motors, power management, dedicated readout board, management board for voltage settings, temperature sensors and temperature controller and optical amplifier. Part of the electronics is developed using the MicroTCA standard. We will present in this poster the basic requirements for the BAM, software design and implementation developed to manage the subsystems and their interactions.

	A state in which accelerator system works at a given moment of time is determined by the state machine. The idea of the project has been based on FSM - finite state machine, in which each of the states is precisely determined by assigned specified operations on subsystem devices of the accelerator system such as e.g. magnets of storage rings, RF transmitters etc. To ensure high reliability, the main part of the project has been based on PLC - Programmable Logic Controller. StateMachine wich is a TangoClass has been written in Python using the facadedevice library, that allows information from the control system to be delivered to the PLC system. By using an universal Tango Class AllenBradleyEIP the state machine shering an informationa about accelerator system to the Tango control system. This information is archived in Cassandra database system by using the Tango HDB++ archiving system.

	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-SC0012704 with the U.S. Department of Energy. The development of HTTP service interfaces* to the BNL Collider-Accelerator Department (C-AD) controls system opens up the ability to more quickly and easily adapt existing codes developed for other systems for use at RHIC. A simple particle accelerator online model built for commissioning the NSLS II was adapted for use with the Low Energy RHIC electron Cooling project (LEReC)* and the Coherent Electron Cooling (CeC)**** proof of principle experiment. For this project, a set of python modules and a python application were adapted for use in RHIC by replacing NSLS II control system interfaces with python modules that interface to the C-AD controls HTTP services. This paper will discuss the new interfaces and the status of commissioning them for operations. * T. D'Ottavio, et al., these proceedings S. Seletskiy et al., TUPMA054, IPAC15, 2015. * A.

THAPL05	Nomad 3D: Augmented Reality in Instrument Control	ion, controls, software, experiment	1098
	Y. Le Goc, F. Cecillon, P. Mutti ILL, Grenoble, France
	The life cycle of an ILL instrument has two main stages. During the design of the instrument, a precise but static 3D model of the different components is developed. Then comes the exploitation of the instrument of which the control by the Nomad software allows scientific experiments to be performed. Almost all instruments at the ILL have moveable parts often hidden behind radiological protection elements such as heavy concrete walls or casemate. Massive elements of the sample environment like magnets and cryostats must be aligned in the beam. All those devices are able to collide with the surrounding environment. To avoid those types of accident, the instrument moves must be checked by a pre-experiment simulation that will reveal possible interferences. Nomad 3D is the application that links the design and the experiment aspects providing an animated 3D physical representation of the instrument while it moves. Collision detection algorithms will protect the moveable parts from crashes. During an experiment, it will augment the reality by enabling to "see" behind the walls. It will provide as well a precise virtual representation of the instrument during the simulations.

THCPA03	Applying Layer of Protection Analysis (LOPA) to Accelerator Safety Systems Design	ion, controls, radiation, PLC	1217
	F. Tao, J.M. Murphy SLAC, Menlo Park, California, USA
	Large accelerator safety system design is complex and challenging. The complexity comes from the wide geographical distribution and the entangled control/protection functions that are shared across multiple control systems. To ensure safety performance and avoid unnecessary overdesign, a systematic approach should be followed when setting the functional requirements and the associated safety integrity. Layer of Protection Analysis (LOPA) is a method in IEC61511 for assigning the SIL to a safety function. This method is well suited for complex applications and is widely adopted in the process industry. The outputs of the LOPA study provide not only the basis for setting safety functions design objective, but also a reference document for managing system change and determining test scope. In this paper, SLAC credited safety systems are used to demonstrate the application of this semi-quantitative method. This example will illustrate how to accurately assess the hazardous event, analyze the independence of different protection layers, and determine the reliability of a particular protection function.

THMPL02	Upgrade of KEK Electron/positron Linac Control System for the Both SuperKEKB and Light Sources	ion, experiment, injection, linac	1257

	KEK injector linac has delivered electrons and positrons for particle physics and photon science experiments for more than 30 years. It is being upgraded for the SuperKEKB project, which aims at a 40-fold increase in luminosity over the previous project of KEKB, in order to increase our understanding of flavour physics. This project requires ten-times smaller emittance and five-times larger current in injection beam from the injector. And many hardware components are being tested and installed. Even during the 6-year upgrade, it was requested to inject beams into light sources storage rings of PF and PF-AR. Furthermore, the beam demanding approaches from those storage rings are different. SuperKEKB would demand highest performance, and unscheduled interruption may be acceptable if the performance would be improved. However, light sources expect a stable operation without any unscheduled break, mainly because most users run experiments for a short period. In order to deal with the both requirements several measures are taken for operation, construction and maintenance strategy including simultaneous top-up injections.

THPHA025	LCLS-II Injector Laser System	ion, laser, controls, timing	1397
	S.C. Alverson, D.E. Anderson, S. Gilevich SLAC, Menlo Park, California, USA
	Funding: SLAC National Accelerator Lab - LCLS-II The Linac Coherent Light Source II (LCLSII) is a new Free Electron Laser (FEL) facility being built as an upgrade to the existing LCLS-I and is planned for early commissioning this year (2017) and full operation in 2020. The injector laser which hits the cathode to produce the electrons for this FEL source is conceptually similar to LCLS-I, but will utilize an upgraded controls architecture in order to be compatible with the faster repetition rate (1 MHz) of the beam. This includes moving to industrial PCs from VME and utilizing SLAC designed PCIe timing cards and camera framegrabbers. This poster discusses the overall architecture planned for this installation and discusses the reasoning behind the choices of hardware and control scheme.

	The Phase I beam commissioning of SuperKEKB has been conducted from February to June in the last year. The injector linac has successfully delivered the electron and positron beams to the SuperKEKB main ring. The linac beam studies and subsystem developments are also intensively going on together with the daily normal beam injection to both rings of the SuperKEKB and two light sources. Towards Phase II and III beam commissioning of SuperKEKB, one of key issues is a fine beam control with the new beam position monitor readout system, a positron capture system based on the flux concentrator, a pulsed quadrupole and steering magnets, and a low emittance photo-cathode rf electron source. In this paper, we report the control system status of SuperKEKB injector linac together with the commissioning result of Phase I. In addition, the improvement plant of injector control system is also mentioned.

THPHA069	Control System for Atlas Tilecal HVremote Boards	ion, controls, interface, Ethernet	1543

	Funding: Funding from FCT (Portuguese government funding agency of the MCTES); project "ColaboracÃ£o na ExperiÃªncia ATLAS", CERN/FISNUC/0005/2015 One of the proposed solutions for upgrading the high voltage (HV) system of Tilecal, the ATLAS hadron calorimeter, consists in removing the HV regulation boards from the detector and deploying them in a low-radiation room where there is permanent access for maintenance. This option requires many ~100m long HV cables but removes the requirement of radiation hard boards. That solution simplifies the control system of the HV regulation cards (called HVRemote). It consists of a Detector Control System (DCS) node linked to 256 HVRemote boards through a tree of Ethernet connections. Each HVRemote includes a smart Ethernet transceiver for converting data and commands from the DCS into serial peripheral interface (SPI) signals routed to SPI-capable devices in the HVRemote. The DCS connection to the transceiver and the control of some SPI-capable devices via Ethernet has been tested successfully. It was fabricated a test board (HVRemote-ctrl) with the interfacing sub-system of the HVRemote. It is being tested through SPI-interfaces and several devices were already validated. A next version adds a few more ADC/DAC devices for checking their suitability for the final design.

THPHA071	Plans at CERN for Electronics and Communication in the Distributed I/O Tier	ion, radiation, FPGA, electronics	1552
	G. Daniluk, E. Gousiou CERN, Geneva, Switzerland
	Controls and data acquisition in accelerators often involve some kind of computing platform (VME, PICMG 1.3, MTCA.4…) connected to Distributed I/O Tier electronics using a fieldbus or another kind of serial link. At CERN, we have started a project to rationalize this tier, providing a modular centrally-supported platform which allows equipment groups to focus on solving their particular problems while benefiting from a set of well-debugged building blocks. The paper describes the strategy, based on 3U Euro crates with a generic FPGA-based board featuring space for FMC mezzanines. Different mezzanines allow communication using different protocols. There are two variants of the electronics, to deploy in environments with and without radiation tolerance requirements. The plans we present are the result of extensive discussion at CERN among all stakeholders. We present them here with the aim of gathering further feedback and potential interest for inter-lab collaborations.

THPHA141	Design of the Front-End Detector Control System of the ATLAS New Small Wheels	ion, detector, interface, electronics	1710
	P.V. Moschovakos, A. Koulouris NTUA, Athens, Greece
	Funding: For the ATLAS Muon Collaboration The foreseen upgrades of the LHC accelerator and the experiments will drastically increase the data and trigger rates. To cope with the vast and low latency data flow, the ATLAS small wheel muon detector will be replaced with a New Small Wheel. Among the upgrades needed, is a radiation tolerant Slow Control Adapter (GBT-SCA) ASIC dedicated for the on-detector control and monitoring. The ASIC employs various interfaces, making it flexible to match the needs of the different operations. On the backend, the Front-End Link eXchange system will be the interface between the data handling system and the detector front-end and trigger electronics. A dedicated slow control data component was developed as the middleware from FELIX to the end users. It is based on the OPC Unified Architecture protocol and it is comprised of an OPC-UA server, that will handle the slow control traffic from the control room to the GBT-SCA and vice versa. Ultimately, various scope-oriented OPC-UA clients, connected to the OPC-UA server, will be employed to configure and calibrate the ASICs, program the FPGAs, oversee the well-functioning of the boards and monitor the environmental parameters of the detector.

	This paper presents the proposed communication architecture of the Detector Control System (DCS) for the Inner Tracking System (ITS). The purpose of the DCS is to acquire and control the states of the ITS. Since the ITS is not yet fully implemented, an emulator of the communication architecture is being developed. The proposed architecture comprises five levels. At the bottom, the detector is emulated by sensors connected to microcontrollers. Each microcontroller is then connected to a Raspberry Pi which represents the ALICE low-level front-end (ALF) electronics at the second level of communication architecture. The third level is represented by Front-End Device (FRED), a Linux server where more than one ALF device can be connected. FRED is then connected to the fourth level, implemented by the SCADA interface - WinCC OA. Above all these levels is an archiving and configuration database setup. Configuration bypasses the SCADA interface and is managed directly through FRED. The purpose of the emulator is to verify the proposed architecture in terms of data throughput and cooperation of the mentioned modules.

	At the SPring-8 site, the X-ray free electron laser facility, SACLA, and the third generation light source, SPring-8 storage ring, is operated. The SACLA generate brilliant coherent X-ray beams with wavelength of below 0.1nm and the SPring-8 provides brilliant X-ray to large number of experimental users. On the SPring-8 upgrade project we have a plan to use the linac of SACLA for a full-energy injector. For this purpose, two accelerators should be controlled seamlessly and the SACLA has to operate as to generate X-ray laser and injector for the SPring-8 simultaneously. We start the design of control system to meet those requirements. We redesign all of a control framework such as Database, Messaging System and Equipment Control include with NoSQL database, MQTT and EtherCAT. In this paper, we will report the design of control system for SACLA/SPring-8 together with status of the SPring-8 upgrade project.

The SwissFEL is a new free electron laser facility at the Paul Scherrer Institute (PSI) in Switzerland. Commissioning started in 2016 and resulted in first lasing in December 2016 (albeit not on the design energy). In 2017, the commissioning continued and will result in the first pilot experiments at the end of the year. The close interaction of experiment and accelerator components as well as the pulsed electron beam required a well thought out integration of the control system including some new concepts and layouts. This paper presents the current status of the control system together with some lessons learned.

The ambitious upgrade plan of the ALICE experiment expects a complete redesign of its data flow after the LHC shutdown scheduled for 2019, for which new electronics modules are being developed in the collaborating institutes. Access to prototypes is at present very limited and full scale prototypes are expected only close to the installation date. To overcome the lack of realistic HW, the ALICE DCS team built small-scale prototypes based on low-cost commercial components (Arduino, Raspberry PI), equipped with environmental sensors, and installed in the experiment areas around and inside the ALICE detector. Communication and control software was developed, based on the architecture proposed for the future detectors, including CERN JCOP FW and ETM WINCC OA. Data provided by the prototypes has been recorded for several months, in presence of beam and magnetic field. The challenge of the harsh environment revealed some insurmountable weaknesses, thus excluding this class of devices from usage in a production setup. They did prove, however, to be robust enough for test purposes, and are still a realistic test-bed for developers while the production of final electronics is continuing.

CAEP, Sichuan, People's Republic of China

The inspection and tracking of laser-induced damages of optics play a significant role in high-power laser systems. Laser-induced defects or flaws on the surfaces of optics are presented in images acquired by specific charge coupled devices (CCDs), hence the identification of defects from laser damage images is essential. Despite a great effort we have made to improve the imaging results, the defect identification is a challenging task. The proposed research focuses on the pre-processing of laser damage images, which assists identifying optic defects. We formulate the image pre-processing as a total variation (TV) based image reconstruction problem, and further develop an alternating direction method of multipliers (ADMM) algorithm to solve it. The use of TV regularization makes the pre-processed image sharper by preserving the edges or boundaries more accurately. Experimental results demonstrate the effectiveness of this method.

The MIS section in the Computing division at ALBA Synchrotron designs and supports management information systems. This paper describes the streamlining of the work of 12 support groups into a single customer portal and issue management system. Prior to the change, ALBA was using five different ticket systems. To improve coordination, we searched tools able to support ITIL Service Management, as well as PRINCE2 and Agile Project Management. Within market solutions, JIRA, with its agile boards, calendars, SLAs and service desks, was the only solution with a seamless integration of both. Support teams took the opportunity to redesign their service portfolio and management processes. Through the UX design, JIRA has proved to be a flexible solution to customize forms, workflows, permissions and notifications on the fly, creating a virtuous cycle of rapid improvements, a rewarding co-design experience which results in highly fitting solutions and fast adoption. Team, project and service managers now use a single system to track requests in a timely manner, view trends, and get a consolidated view of efforts invested in the different beamlines and accelerators.

Despite the large number of feedback loops running simultaneously at the FERMI Free Electron Laser (FEL), they are not sufficient to keep the optimal machine working point in the long term, in particular when the machine is tuned in such a way to be more sensitive to drifts of the critical parameters. In order to guarantee the best machine performance, a novel software application which minimizes the shot to shot correlation between these critical parameters and the FEL radiation has been implemented. This application, which keeps spatially and temporally aligned the seed laser and the electron beam, contrary to many algorithms that inject noise in the system to be optimized, run transparently during the experiment beam times. In this paper we will also present a newly developed method to calculate a beam 'quality factor' starting from the images provided by a photon spectrometer, which tries to mimic the evaluation of machine physicists, as well as the results obtained using two model-less algorithms to optimize the FEL performance through maximization of the quality factor.

Research on Fault Diagnosis of Power Supply Control System on BEPCII

D. Wang, J. Liu, X.L. Wang
IHEP, Beijing, People's Republic of China

The reliable and stable operation of the accelerator is the premise and foundation of physics experiments. For example, in the BEPCII, the fault of the magnet power supply front-end electronics devices may cause accelerator energy instability and even lead to beam loss. Therefore, it is very necessary to diagnose and locate the device fault accurately and rapidly, that will induce the high cost of the accelerator operation. Faults diagnosis can not only improve the safety and reliability of the equipment, but also effectively reduce the equipment's cycle costing. The multi-signal flow model proposed by Pattipati K.R is considered as the preferred method of industrial equipment faults detection. However, there are still some problems about fault probability conflict in the processing of correlation matrix diagnosis due to the hierarchical nature of multi-signal flow modeling. Thus we develop the fault diagnosis strategy based on the important prior knowledge of the fault. This method is applied to the front-end electronic devices of BEPCII magnet power supply control system and improves the fault diagnosis and analysis ability of magnet power supply control system.

In NSC KIPT, Kharkov, Ukraine the state of art nuclear facility Neutron Source on the base of subcritical assembly driven with 100 MeV/100 kW electron linear accelerator has been build. The electron beam generates neutrons during bombarding the tungsten or uranium target. The subcritical assembly of low enrichment uranium is used to multiply the initial neutrons due to fission of the uranium nuclei. The facility is the first world facility of such kind. It is supposed that maximal value of multiplying neutron factor in the source will be equal to 0.95. So, the neutron flux will be increased as much as 50 times. Because of sub-criticality the facility eliminates the possibility to produce the self-sustained chain reaction. Now the Neutron source is under commissioning. In the report the facility and its control system current status is presented.

Funding: The work described was funded by the U.S. Department of Energy, Office of Science via the Isotope Development and Production for Research and Applications subprogram in the Office of Nuclear Physics.
Isotopes produced at Los Alamos National Laboratory (LANL) are saving lives, advancing cutting-edge research, and helping to address national security questions. For the past two years LANL's Accelerator Operations & Technology Division has executed a $6.4M improvement project for the Isotope Production Facility. The goals are to reduce the programmatic risk and enhance facility reliability while at the same time pursuing opportunities to increase general isotope production capacity. This has led to some exciting innovations. In this paper we will discuss the engineering designs for our new collimator, which is both adjustable and 'active' (i.e. equipped with beam current and temperature measurements), as well as our upgraded beam raster system and new beam diagnostics capabilities. We will also report on results obtained and lessons learned from the commissioning phase and initial production run.

Synchrotron facilities provides short, regular and high frequency flashes of light. These pulses are used by the scientific community for time resolved experiments. To improve the time resolution, demands for always shorter X-ray pulses are growing. To achieve this goal, Synchrotron SOLEIL and MAX IV laboratory have developed special operating modes such as low-alpha and femtoslicing, as well as a single pass linear accelerator. For the most demanding experiments, the synchronization between short light pulses and pump-probe devices requires sub-picoseconds delay adjustment. The TimIQ system has been developed for that purpose. It is a joint development between Synchrotron Soleil and MAX IV Laboratory. It is aimed to be used on three beamlines at Soleil and one at MAX IV. Based on IQ modulation technics, it allows shifting a radio frequency clock by steps of #100 fs. This paper is a description of this system and of its performances.

The I10 beamline at Diamond Light Source is configured to study circular dichroism. To increase signal to noise ratio between the two beam polarisations and increase temporal resolution the beamline is fed by two separate IDs that are typically configured with opposite handed polarisations. A chicane of steering magnets with programmable power supplies is used to provide 10 Hz switching between the two photon beams by producing a dynamic closed bump that alternates the on-axis trajectory of the electron beam between the two IDs. In order to maintain the closed bump and make the switching transparent to the rest of the photon beamlines the phase and amplitude of the sine functions applied to the chicane magnets must be exactly correct. In this paper the linear scheme that was used to correct the residual 10 Hz orbit distortion is presented. Future work that uses the fully programmable nature of the magnet power supply controllers to correct high order distortions is also discussed.

In modern free electron laser facilities like FLASH I/II and European XFEL at DESY a high resolution intra bunch train arrival time measurement is mandatory, providing a crucial information for the beam based feedback system. For this purpose a Bunch Arrival Time Monitor (BAM) was developed, based on an electro-optical scheme where an ultra-short pulsed laser is employed. A BAM is composed of several subsystems, including stepper motors, power management, dedicated readout board, management board for voltage settings, temperature sensors and temperature controller and optical amplifier. Part of the electronics is developed using the MicroTCA standard. We will present in this poster the basic requirements for the BAM, software design and implementation developed to manage the subsystems and their interactions.

A state in which accelerator system works at a given moment of time is determined by the state machine. The idea of the project has been based on FSM - finite state machine, in which each of the states is precisely determined by assigned specified operations on subsystem devices of the accelerator system such as e.g. magnets of storage rings, RF transmitters etc. To ensure high reliability, the main part of the project has been based on PLC - Programmable Logic Controller. StateMachine wich is a TangoClass has been written in Python using the facadedevice library, that allows information from the control system to be delivered to the PLC system. By using an universal Tango Class AllenBradleyEIP the state machine shering an informationa about accelerator system to the Tango control system. This information is archived in Cassandra database system by using the Tango HDB++ archiving system.

The development of HTTP service interfaces* to the BNL Collider-Accelerator Department (C-AD) controls system opens up the ability to more quickly and easily adapt existing codes developed for other systems for use at RHIC. A simple particle accelerator online model built for commissioning the NSLS II** was adapted for use with the Low Energy RHIC electron Cooling project (LEReC)*** and the Coherent Electron Cooling (CeC)**** proof of principle experiment. For this project, a set of python modules and a python application were adapted for use in RHIC by replacing NSLS II control system interfaces with python modules that interface to the C-AD controls HTTP services. This paper will discuss the new interfaces and the status of commissioning them for operations.

Nomad 3D: Augmented Reality in Instrument Control

ion, controls, software, experiment

ILL, Grenoble, France

The life cycle of an ILL instrument has two main stages. During the design of the instrument, a precise but static 3D model of the different components is developed. Then comes the exploitation of the instrument of which the control by the Nomad software allows scientific experiments to be performed. Almost all instruments at the ILL have moveable parts often hidden behind radiological protection elements such as heavy concrete walls or casemate. Massive elements of the sample environment like magnets and cryostats must be aligned in the beam. All those devices are able to collide with the surrounding environment. To avoid those types of accident, the instrument moves must be checked by a pre-experiment simulation that will reveal possible interferences. Nomad 3D is the application that links the design and the experiment aspects providing an animated 3D physical representation of the instrument while it moves. Collision detection algorithms will protect the moveable parts from crashes. During an experiment, it will augment the reality by enabling to "see" behind the walls. It will provide as well a precise virtual representation of the instrument during the simulations.

SLAC, Menlo Park, California, USA

Large accelerator safety system design is complex and challenging. The complexity comes from the wide geographical distribution and the entangled control/protection functions that are shared across multiple control systems. To ensure safety performance and avoid unnecessary overdesign, a systematic approach should be followed when setting the functional requirements and the associated safety integrity. Layer of Protection Analysis (LOPA) is a method in IEC61511 for assigning the SIL to a safety function. This method is well suited for complex applications and is widely adopted in the process industry. The outputs of the LOPA study provide not only the basis for setting safety functions design objective, but also a reference document for managing system change and determining test scope. In this paper, SLAC credited safety systems are used to demonstrate the application of this semi-quantitative method. This example will illustrate how to accurately assess the hazardous event, analyze the independence of different protection layers, and determine the reliability of a particular protection function.

KEK injector linac has delivered electrons and positrons for particle physics and photon science experiments for more than 30 years. It is being upgraded for the SuperKEKB project, which aims at a 40-fold increase in luminosity over the previous project of KEKB, in order to increase our understanding of flavour physics. This project requires ten-times smaller emittance and five-times larger current in injection beam from the injector. And many hardware components are being tested and installed. Even during the 6-year upgrade, it was requested to inject beams into light sources storage rings of PF and PF-AR. Furthermore, the beam demanding approaches from those storage rings are different. SuperKEKB would demand highest performance, and unscheduled interruption may be acceptable if the performance would be improved. However, light sources expect a stable operation without any unscheduled break, mainly because most users run experiments for a short period. In order to deal with the both requirements several measures are taken for operation, construction and maintenance strategy including simultaneous top-up injections.

The Linac Coherent Light Source II (LCLSII) is a new Free Electron Laser (FEL) facility being built as an upgrade to the existing LCLS-I and is planned for early commissioning this year (2017) and full operation in 2020. The injector laser which hits the cathode to produce the electrons for this FEL source is conceptually similar to LCLS-I, but will utilize an upgraded controls architecture in order to be compatible with the faster repetition rate (1 MHz) of the beam. This includes moving to industrial PCs from VME and utilizing SLAC designed PCIe timing cards and camera framegrabbers. This poster discusses the overall architecture planned for this installation and discusses the reasoning behind the choices of hardware and control scheme.

The Phase I beam commissioning of SuperKEKB has been conducted from February to June in the last year. The injector linac has successfully delivered the electron and positron beams to the SuperKEKB main ring. The linac beam studies and subsystem developments are also intensively going on together with the daily normal beam injection to both rings of the SuperKEKB and two light sources. Towards Phase II and III beam commissioning of SuperKEKB, one of key issues is a fine beam control with the new beam position monitor readout system, a positron capture system based on the flux concentrator, a pulsed quadrupole and steering magnets, and a low emittance photo-cathode rf electron source. In this paper, we report the control system status of SuperKEKB injector linac together with the commissioning result of Phase I. In addition, the improvement plant of injector control system is also mentioned.

One of the proposed solutions for upgrading the high voltage (HV) system of Tilecal, the ATLAS hadron calorimeter, consists in removing the HV regulation boards from the detector and deploying them in a low-radiation room where there is permanent access for maintenance. This option requires many ~100m long HV cables but removes the requirement of radiation hard boards. That solution simplifies the control system of the HV regulation cards (called HVRemote). It consists of a Detector Control System (DCS) node linked to 256 HVRemote boards through a tree of Ethernet connections. Each HVRemote includes a smart Ethernet transceiver for converting data and commands from the DCS into serial peripheral interface (SPI) signals routed to SPI-capable devices in the HVRemote. The DCS connection to the transceiver and the control of some SPI-capable devices via Ethernet has been tested successfully. It was fabricated a test board (HVRemote-ctrl) with the interfacing sub-system of the HVRemote. It is being tested through SPI-interfaces and several devices were already validated. A next version adds a few more ADC/DAC devices for checking their suitability for the final design.

CERN, Geneva, Switzerland

Controls and data acquisition in accelerators often involve some kind of computing platform (VME, PICMG 1.3, MTCA.4…) connected to Distributed I/O Tier electronics using a fieldbus or another kind of serial link. At CERN, we have started a project to rationalize this tier, providing a modular centrally-supported platform which allows equipment groups to focus on solving their particular problems while benefiting from a set of well-debugged building blocks. The paper describes the strategy, based on 3U Euro crates with a generic FPGA-based board featuring space for FMC mezzanines. Different mezzanines allow communication using different protocols. There are two variants of the electronics, to deploy in environments with and without radiation tolerance requirements. The plans we present are the result of extensive discussion at CERN among all stakeholders. We present them here with the aim of gathering further feedback and potential interest for inter-lab collaborations.

Funding: For the ATLAS Muon Collaboration
The foreseen upgrades of the LHC accelerator and the experiments will drastically increase the data and trigger rates. To cope with the vast and low latency data flow, the ATLAS small wheel muon detector will be replaced with a New Small Wheel. Among the upgrades needed, is a radiation tolerant Slow Control Adapter (GBT-SCA) ASIC dedicated for the on-detector control and monitoring. The ASIC employs various interfaces, making it flexible to match the needs of the different operations. On the backend, the Front-End Link eXchange system will be the interface between the data handling system and the detector front-end and trigger electronics. A dedicated slow control data component was developed as the middleware from FELIX to the end users. It is based on the OPC Unified Architecture protocol and it is comprised of an OPC-UA server, that will handle the slow control traffic from the control room to the GBT-SCA and vice versa. Ultimately, various scope-oriented OPC-UA clients, connected to the OPC-UA server, will be employed to configure and calibrate the ASICs, program the FPGAs, oversee the well-functioning of the boards and monitor the environmental parameters of the detector.

This paper presents the proposed communication architecture of the Detector Control System (DCS) for the Inner Tracking System (ITS). The purpose of the DCS is to acquire and control the states of the ITS. Since the ITS is not yet fully implemented, an emulator of the communication architecture is being developed. The proposed architecture comprises five levels. At the bottom, the detector is emulated by sensors connected to microcontrollers. Each microcontroller is then connected to a Raspberry Pi which represents the ALICE low-level front-end (ALF) electronics at the second level of communication architecture. The third level is represented by Front-End Device (FRED), a Linux server where more than one ALF device can be connected. FRED is then connected to the fourth level, implemented by the SCADA interface - WinCC OA. Above all these levels is an archiving and configuration database setup. Configuration bypasses the SCADA interface and is managed directly through FRED. The purpose of the emulator is to verify the proposed architecture in terms of data throughput and cooperation of the mentioned modules.

At the SPring-8 site, the X-ray free electron laser facility, SACLA, and the third generation light source, SPring-8 storage ring, is operated. The SACLA generate brilliant coherent X-ray beams with wavelength of below 0.1nm and the SPring-8 provides brilliant X-ray to large number of experimental users. On the SPring-8 upgrade project we have a plan to use the linac of SACLA for a full-energy injector. For this purpose, two accelerators should be controlled seamlessly and the SACLA has to operate as to generate X-ray laser and injector for the SPring-8 simultaneously. We start the design of control system to meet those requirements. We redesign all of a control framework such as Database, Messaging System and Equipment Control include with NoSQL database, MQTT and EtherCAT. In this paper, we will report the design of control system for SACLA/SPring-8 together with status of the SPring-8 upgrade project.
