	Funding: This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344 The National Ignition Facility (NIF) is the world's largest and most energetic laser experimental facility with 192 beams capable of delivering 1.8 megajoules of 500-terawatt ultraviolet laser energy to a target. The energy, temperatures and pressures capable of being generated on the NIF allow scientists the ability to generate conditions similar to the center of the sun and explore the physics of planetary interiors, supernovae, black holes and thermonuclear burn. This year concludes a very successful multi-year plan of optimizations to the control & information systems and operational processes to increase the quantity of experimental target shots conducted in the facility. In addition, many new system control and diagnostic capabilities have been commissioned for operational use to maximize the scientific value produced. With NIF expecting to be operational for greater than 20 years focus has also been placed on optimizing the software processes to improve the sustainability of the control system. This talk will report on the current status of each of these areas in support of the wide variety of experiments being conducted in the facility. Release No.: LLNL-ABS-727237-DRAFT

MOCPL02	Experiences with Laser Survey Instrument Based Approach to National Ignition Facility Diagnostic Alignments	ion, alignment, diagnostics, laser	52
	E.F. Wilson, M.A. Fedorov, J.R. Hoffman, W.A. Howes, M.J. Lewis, C.L.M. Martinez-Nieves, V. Pacheu, N. Shingleton LLNL, Livermore, California, USA
	Funding: This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. The National Ignition Facility (NIF) uses powerful lasers to compress targets, to study high energy density physics. Sophisticated diagnostics are placed close to the targets to record the results of each shot. The placement of these diagnostics relative to the target is critical to the mission, with alignment tolerances on the order of 500 microns. The integration of commercial laser-based survey instruments into the NIF control system has improved diagnostic alignment in many ways. The Advanced Tracking Laser Alignment System (ATLAS) project incorporates commercial Faro laser tracker instruments into the diagnostic factory and the target chamber, improving alignment accuracy over prior systems. The system uses multiple retroreflectors mounted on each of the diagnostic positioners to translate to a 6D position in the NIF target chamber volume. This enables a closed loop alignment process to align each diagnostic. This paper provides an overview of how the laser tracker is used in diagnostic alignment, and discusses challenges met by the control system to achieve this integration.

TUMPL05	Strategies for Migrating to a New Experiment Setup Tool at the National Ignition Facility	ion, experiment, interface, diagnostics	311
	A.D. Casey, R.G. Beeler, C.D. Fry, J. Mauvais, E.R. Pernice, M. Shor, J.L. Spears, D.E. Speck, S.L. West LLNL, Livermore, California, USA
	Funding: This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. For the last 10 years, the National Ignition Facility (NIF) has provided scientists with an application, the Campaign Management Tool (CMT), to define the parameters needed to achieve their experimental goals. Conceived to support the commissioning of the NIF, CMT allows users to define over 18,000 settings. As NIF has transitioned to an operational facility, the low-level focus of CMT is no longer required by most users and makes setting up experiments unnecessarily complicated. At the same time, requirements have evolved as operations has identified new functionality required to achieve higher shot execution rates. Technology has also changed since CMT was developed, with the availability of the internet and web-based tools being two of the biggest changes. To address these requirements while adding new laser and diagnostic capabilities, NIF has begun to replace CMT with the Shot Setup Tool (SST). This poses challenges in terms of software development and deployment as the introduction of the new tool must be done with minimal interruption to ongoing operations. The development process, transition strategies and technologies chosen to migrate from CMT to SST will be presented. LLNL-ABS-728212

TUMPA01	New Visual Alignment Sequencer Tool Improves Efficiency of Shot Operations at the National Ignition Facility (NIF)	ion, alignment, controls, software	328
	M.A. Fedorov, J.R. Castro Morales, V. Pacheu, E.F. Wilson LLNL, Livermore, California, USA
	Funding: This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344 LLNL-ABS-728701 Established control systems for scientific experimental facilities offer several levels of user interfaces to match domain-specific needs and preferences of experimentalists, operational and engineering staff. At the National Ignition Facility, the low-level device panels address technicians' need for comprehensive hardware control, while Shot Automation software allows NIF Shot Director to advance thousands of devices at once through a carefully orchestrated shot sequence. MATLAB scripting with NIF Layering Toolbox has enabled formation of intricate Deuterium-Tritium ice layers for fusion experiments. The latest addition to this family of user interfaces is the Target Area Alignment Tool (TAAT), which guides NIF operators through hundreds of measurement and motion steps necessary to precisely align targets and diagnostics for each experiment inside of the NIF's 10-meter target chamber. In this paper, we discuss how this new tool has integrated familiar spreadsheet calculations with intuitive visual aids and checklist-like scripting to allow NIF Process Engineers to automate and streamline alignment sequences, contributing towards NIF Shot Rate enhancement goals.

TUMPA04	Operation Status of J-PARC MR Machine Protection System and Future Plan	ion, operation, experiment, power-supply	341
	T. Kimura KEK, Ibaraki, Japan K.C. Sato J-PARC, KEK & JAEA, Ibaraki-ken, Japan
	The J-PARC MR's Machine Protection System (MR-MPS) was introduced from the start of beam operation in 2008. Since then, MR-MPS has contributed to the improvement of safety including stable operation of the accelerator and the experiment facilities. The present MR-MPS needs to be reviewed from the aspects such as increase of connected equipment, addition of power supply building, flexible beam abort processing, module uniqueness, service life etc. In this paper, we show the performance of MR-MPS and show future consideration of upgrade.

TUPHA013	Accelerator Fault Tracking at CERN	ion, operation, controls, distributed	397
	C. Roderick, L. Burdzanowski, D. Martin Anido, S. Pade, P. Wilk CERN, Geneva, Switzerland
	CERNs Accelerator Fault Tracking (AFT) system aims to facilitate answering questions like: "Why are we not doing Physics when we should be?" and "What can we do to increase machine availability?" People have tracked faults for many years, using numerous, diverse, distributed and un-related systems. As a result, and despite a lot of effort, it has been difficult to get a clear and consistent overview of what is going on, where the problems are, how long they last for, and what is the impact. This is particularly true for the LHC, where faults may induce long recovery times after being fixed. The AFT project was launched in February 2014 as collaboration between the Controls and Operations groups with stakeholders from the LHC Availability Working Group (AWG). The AFT system has been used successfully in operation for LHC since 2015, yielding a lot of attention and generating a growing user community. In 2017 the scope has been extended to cover the entire Injector Complex. This paper will describe the AFT system and the way it is used in terms of architecture, features, user communities, workflows and added value for the organisation.

TUPHA019	Optimized Calculation of Timing for Parallel Beam Operation at the FAIR Accelerator Complex	ion, MMI, software, heavy-ion	411
	A. Schaller, J. Fitzek GSI, Darmstadt, Germany D. Lorenz, F. Wolf TU Darmstadt, Darmstadt, Germany
	For the new FAIR accelerator complex at GSI the settings management system LSA is used. It is developed in collaboration with CERN and until now it is executed strictly serial. Nowadays the performance gain of single core processors have nearly stagnated and multicore processors dominate the market. This evolution forces software projects to make use of the parallel hardware to increase their performance. In this thesis LSA is analyzed and parallelized using different parallelization patterns like task and loop parallelization. The most common case of user interaction is to change specific settings so that the accelerator performs at its best. For each changed setting, LSA needs to calculate all child settings of the parameter hierarchy. To maximize the speedup of the calculations, they are also optimized sequentially. The used data structures and algorithms are reviewed to ensure minimal resource usage and maximal compatibility with parallel execution. The overall goal of this thesis is to speed up the calculations so that the results can be shown in a user interface with nearly no noticeable latency.

TUPHA061	Status of the NSC KIPT Neutron Source	ion, neutron, shielding, electron	537
	O. Bezditko, I.M. Karnaukhov, A. Mytsykov, D.V. Tarasov, A.Y. Zelinsky NSC/KIPT, Kharkov, Ukraine
	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

TUPHA088	Timing System at ESS	ion, timing, controls, EPICS	618
	J. Cereijo García, T. Korhonen, J.H. Lee ESS, Lund, Sweden
	The European Spallation Source (ESS) timing system is based on the hardware developed by Micro-Research Finland (MRF). The main purposes of the timing system are: generation and distribution of synchronous clock signals and trigger events to the facility, providing a time base so that data from different systems can be time-correlated and synchronous transmission of beam-related data for for different subsystems of the facility. The timing system has a tree topology: one Event Generator (EVG) sends the events, clocks and data to an array of Event Receivers (EVRs) through an optical distribution layer (fan-out modules). The event clock frequency for ESS will be 88.0525 MHz, divided down from the bunch frequency of 352.21 MHz. An integer number of ticks of this clock will define the beam macro pulse full length, around 2.86 ms, with a repetition rate of 14 Hz. An active delay compensation mechanism will provide stability against long-term drifts. A novelty of ESS compared to other facilities is the use of the features provided by EVRs in uTCA form factor, such as trigger and clock distribution over the backplane. These EVRs are already being deployed in some systems and test stands.

TUPHA129	Motion Control System for the European Spallation Source Target Wheel	ion, controls, radiation, neutron	717
	D.P. Brodrick, T. Gahl, B. Gallese, K. Jurisic, M. Larsson, U. Odén, A. Sandström, K. Sjögreen ESS, Lund, Sweden
	The European Spallation Source (ESS) linear accelerator will deliver high energy proton bunches to tungsten sectors on a rotating Target Wheel, which will produce neutrons through a nuclear process. The motion control system of the Target Wheel presents engineering challenges, such as: velocity and phase stability requirements to precisely align individual tungsten sectors with proton bunches from the accelerator; a high moment of inertia due to the composition and distribution of mass on the wheel; limitations on the physical space to integrate control components, and components for associated safety systems; and, some components being exposed to a high radiation environment. The motion control system being prototyped employs components that satisfy the constraints on the physical space and radiation environment. Precise velocity and phasing of the Target Wheel are achieved by generating a series of pulses as each tungsten sector passes a fiducial point in the rotational cycle, and implementing a motion control algorithm to correctly synchronise the Target Wheel with reference signals from the centralised ESS timing system, which also controls the timing of the accelerator.

TUPHA198	Software Applications for Beam Traceability and Machine Documentation at ISOLDE	ion, ISOL, controls, experiment	905
	E. Fadakis, N. Bidault, M.L. Lozano Benito, E. Matli, J.A. Rodriguez, K.S. Seintaridis CERN, Geneva, Switzerland
	The ISOLDE facility at CERN requires a wide variety of software applications to ensure maximum productivity. It will be further enforced by two new and innovative applications; Automatic Save After set uP (ASAP) and Fast Beam Investigation (FBI). ASAP saves crucial time for the engineers in charge (EIC) during the physics campaign. It automatizes and standardizes a repetitive process. In addition, for each new set up, the EIC is required to document the settings of all important elements before delivering beam to the users. FBI will be serving two different needs. First, it will be used as a beam traceability tool. The settings of every element of ISOLDE that could obstruct, stop or affect the beam will be tracked by the application. This will allow to understand better the presence of radioactive contaminants after each experiment at every possible point in the facility. The second functionality will allow real time monitoring of the machine status during a physics run. FBI will be the most efficient way to visualize the status of the machine and find the reason that prevents the beam from arriving to the experimental station.

	Funding: Brazilian Ministry of Science, Technology, Innovation and Communication The monochromator is known to be one of the most critical optical elements of a synchrotron beamline. It directly affects the beam quality with respect to energy and position, demanding high stability performance and fine position control. The new high-dynamics DCM (Double-Crystal Monochromator) [1] prototyped at the Brazilian Synchrotron Light Laboratory (LNLS), was designed for the future X-ray undulator and superbend beamlines of Sirius, the new Brazilian 4th generation synchrotron [2]. At this kind of machine, the demand for stability is even higher, and conflicts with factors such as high power loads, power load variation, and vibration sources. This paper describes the system identification work carried out for enabling the motion control and thermal control design of the mechatronic parts composing the DCM prototype. The tests were performed in MATLAB/Simulink Real-Time environment, using a Speedgoat Real-Time Performance Machine as a real-time target. Sub-nanometric resolution and nanometric stability at 300 Hz closed loop bandwidth in a MIMO system were targets to achieve. Frequency domain identification tools and control techniques are presented in this paper.

THBPL05	The ELT Linux Development Environment	ion, software, framework, Linux	1125
	F. Pellegrin, C. Rosenquist ESO, Garching bei Muenchen, Germany
	The Extremely Large Telescope is a 39-metre ground-based telescope being built by ESO. It will be the largest optical/near-infrared telescope in the world and first light is foreseen for 2024. The overall ELT Linux development environment will be presented with an in-depth presentation of its core, the waf build system, and the customizations that ESO is currently developing. The ELT software development for telescopes and instruments poses many challenges to cover the different needs of such a complex system:a variety of technologies, Java, C/C++ and Python as programming languages, Qt5 as the GUI toolkit, communication frameworks such as OPCUA, DDS and ZeroMQ, the interaction with entities such as PLCs and real-time hardware, and users, in-house and not, looking at new usage patterns. All this optimized to be on time for the first light. To meet these requirements, a set of tools was selected. Its content ranges from an IDE, to compilers, interpreters, analysis and debugging tools for the various languages and operations. At the heart of the toolkit lies the modern build framework waf:a versatile tool written in Python selected due to its multiple language support and high performance.

THPHA105	ESS Target Safety System Design	ion, PLC, proton, controls	1622
	A. Sadeghzadeh, L. Coney, O. Ingemansson, M. Mansouri, M. Olsson ESS, Lund, Sweden
	The purpose of the Target Safety System (TSS) is to protect the public from exposure to unsafe levels of radiation, prevent the release of radioactive material beyond permissible limits, and bring the neutron spallation function into a safe state. In order to fulfill the necessary safety functions, the TSS continually monitors critical parameters within target station systems. If any parameter exceeds an acceptable level, the TSS actuates contactors to cut power to components at the front end of the accelerator and prevent the beam from reaching the target. The TSS is classified as a safety structure, system and component, relevant for the safety of the public and the environment. As such, it requires the highest level of rigor in design and quality for interlock systems at the ESS. Standards are applied to provide a guideline for building the TSS architecture and designing in resistance to single failures and common cause failures. This paper describes the system architecture and design of the TSS, including interfaces with target station and accelerator systems, and explains how the design complies with authority conditions and requirements imposed by development standards.

THPHA128	Applications of Kalman State Estimation in Current Monitor Diagnostic Systems	ion, feedback, simulation, diagnostics	1673
	J.O. Hill LANL, Los Alamos, New Mexico, USA
	Funding: Work supported by US Department of Energy under contract DE-AC52-06NA25396. Traditionally, designers of transformer-based beam current monitor diagnostic systems are constrained by fundamental trade-offs when reducing distortion in time-domain beam-pulse facsimile waveforms while also attempting to preserve information in the frequency-domain. When modelling the sensor system with a net-work of linear time-invariant passive components, and a state-based representation based on first-order differential equations, we identify two internal dynamical states isolated from each other by the parasitic resistance in the transformer windings. They are the parasitic capacitance voltage across the transformer's windings, and the transformer inductor current. These states are typically imperfectly observed due to noise, component value variance, and sensor component network topology. We will discuss how feedback-based Kalman State Estimation implemented within digital signal-processing might be employed to reduce negative impacts of noise along with component variance, and how Kalman Estimation might also optimize the conflicting goals of beam-pulse facsimile waveform fidelity together with preservation of fre-quency domain information.

THPHA135	Wall Current Monitor Using PXI and LabVIEW at CERN	ion, timing, LabView, controls	1699
	C. Charrondière, M. Delrieux, R. Limpens CERN, Geneva, Switzerland
	The new data acquisition system for the PS ring wall current monitors installed in the PS is able to perform higher frequency measurements of a beam bunch up to a frequency of 2.7 GHz. This is an important improvement, since the oscillating signal within the bandwidth 500-700 MHz, is related to losses of a beam bunch. The losses can be reduced by measuring the frequency and classifying the cause of the oscillations. The PXI-5661 is used to carry out spectral analysis of this signal. The acquisition is performed on a PXI running LabVIEW Real-Time and synchronized using a trigger from the accelerator timing system.

THPHA184	MalcolmJS: a Browser-Based Graphical User Interface	ion, interface, controls, framework	1869
	I.J. Gillingham, T.M. Cobb DLS, Oxfordshire, United Kingdom
	A browser-based graphical user interface has been developed at Diamond. It is known as known as MalcolmJS as it communicates using Diamond's Malcolm Middleware protocol. The original goal was to communicate, via websockets with a PandABox in order to allow a user to examine and set attributes of numerous functional blocks within the instrument. With the continuing maturity of the JavaScript language, in particular the release of ES6, along with the availability of off-the-shelf reactive open-source JavaScript libraries, such as Facebook's React and Node.js, a rich set of tools and frameworks have entered the arena of user interface development suitable for control systems. This paper describes the design decisions based on these tools, experiences and lessons learned during and after the development process and the possibilities for future development as a generic, adaptable framework for instrument and control system user interfaces.

	Funding: The authors would like to gratefully acknowledge the funding by the Brazilian Ministry of Science, Technology, Innovation and Communication. The monochromator is known to be one of the most critical optical elements of a synchrotron beamline. It directly affects the beam quality with respect to energy and position, demanding high stability performance and fine position control. The new high-dynamic double-crystal monochromator (HD-DCM) [1], prototyped at the Brazilian Synchrotron Light Laboratory (LNLS), was designed for the future X-ray undulator and superbend beamlines of Sirius, the new Brazilian 4th generation synchrotron [2]. At this kind of machine, the demand for stability is even higher and conflicts with factors such as high-power loads, power load variation, and vibration sources. To identify and ensure sufficient control of the dynamic behaviour of all subcomponents in the proto-type, an implementation in MATLAB/Simulink Real-Time environment in a Speedgoat Real-Time Perfor-mance Machine was developed. This approach enables rapid prototyping, by allowing a shared environment for system modeling and testing. The tool was developed in a modular architecture aiming at practical model itera-tion and platform migration to standard beamline con-trollers, which can prove portability and scalability fea-tures.

FRAPL06	The Laser MegaJoule Facility: Control System Status Report	ion, controls, laser, operation	2007
	H. Durandeau CEA, LE BARP cedex, France
	The Laser MegaJoule (LMJ) is a 176-beam laser facility, located at the CEA CESTA Laboratory near Bordeaux (France). It is designed to deliver about 1.4 MJ of energy to targets, for high energy density physics experiments, including fusion experiments. The first 8-beams bundle was operated in October 2014 and a new bundle was commissioned in October 2016. The next two bundles are on their way. There are three steps for the validation of a new bundle and its integration to the existing control system. The first step is to verify the ability of every command control subsystems to drive the new bundle using a secondary independent supervisory. It is performed from a dedicated integration control room. The second is to switch the bundle to the main operations control room supervisory. At this stage, we perform the global system tests to validate the commissioning of the new bundle. In this paper we focus on the switch of a new bundle from the integration control room to the main operations control room. We have to connect all equipment controllers of the bundle to the operations network and update the Facility Configuration Management.

The National Ignition Facility (NIF) is the world's largest and most energetic laser experimental facility with 192 beams capable of delivering 1.8 megajoules of 500-terawatt ultraviolet laser energy to a target. The energy, temperatures and pressures capable of being generated on the NIF allow scientists the ability to generate conditions similar to the center of the sun and explore the physics of planetary interiors, supernovae, black holes and thermonuclear burn. This year concludes a very successful multi-year plan of optimizations to the control & information systems and operational processes to increase the quantity of experimental target shots conducted in the facility. In addition, many new system control and diagnostic capabilities have been commissioned for operational use to maximize the scientific value produced. With NIF expecting to be operational for greater than 20 years focus has also been placed on optimizing the software processes to improve the sustainability of the control system. This talk will report on the current status of each of these areas in support of the wide variety of experiments being conducted in the facility.

The National Ignition Facility (NIF) uses powerful lasers to compress targets, to study high energy density physics. Sophisticated diagnostics are placed close to the targets to record the results of each shot. The placement of these diagnostics relative to the target is critical to the mission, with alignment tolerances on the order of 500 microns. The integration of commercial laser-based survey instruments into the NIF control system has improved diagnostic alignment in many ways. The Advanced Tracking Laser Alignment System (ATLAS) project incorporates commercial Faro laser tracker instruments into the diagnostic factory and the target chamber, improving alignment accuracy over prior systems. The system uses multiple retroreflectors mounted on each of the diagnostic positioners to translate to a 6D position in the NIF target chamber volume. This enables a closed loop alignment process to align each diagnostic. This paper provides an overview of how the laser tracker is used in diagnostic alignment, and discusses challenges met by the control system to achieve this integration.

For the last 10 years, the National Ignition Facility (NIF) has provided scientists with an application, the Campaign Management Tool (CMT), to define the parameters needed to achieve their experimental goals. Conceived to support the commissioning of the NIF, CMT allows users to define over 18,000 settings. As NIF has transitioned to an operational facility, the low-level focus of CMT is no longer required by most users and makes setting up experiments unnecessarily complicated. At the same time, requirements have evolved as operations has identified new functionality required to achieve higher shot execution rates. Technology has also changed since CMT was developed, with the availability of the internet and web-based tools being two of the biggest changes. To address these requirements while adding new laser and diagnostic capabilities, NIF has begun to replace CMT with the Shot Setup Tool (SST). This poses challenges in terms of software development and deployment as the introduction of the new tool must be done with minimal interruption to ongoing operations. The development process, transition strategies and technologies chosen to migrate from CMT to SST will be presented.

Established control systems for scientific experimental facilities offer several levels of user interfaces to match domain-specific needs and preferences of experimentalists, operational and engineering staff. At the National Ignition Facility, the low-level device panels address technicians' need for comprehensive hardware control, while Shot Automation software allows NIF Shot Director to advance thousands of devices at once through a carefully orchestrated shot sequence. MATLAB scripting with NIF Layering Toolbox has enabled formation of intricate Deuterium-Tritium ice layers for fusion experiments. The latest addition to this family of user interfaces is the Target Area Alignment Tool (TAAT), which guides NIF operators through hundreds of measurement and motion steps necessary to precisely align targets and diagnostics for each experiment inside of the NIF's 10-meter target chamber. In this paper, we discuss how this new tool has integrated familiar spreadsheet calculations with intuitive visual aids and checklist-like scripting to allow NIF Process Engineers to automate and streamline alignment sequences, contributing towards NIF Shot Rate enhancement goals.

CERN, Geneva, Switzerland

CERNs Accelerator Fault Tracking (AFT) system aims to facilitate answering questions like: "Why are we not doing Physics when we should be?" and "What can we do to increase machine availability?" People have tracked faults for many years, using numerous, diverse, distributed and un-related systems. As a result, and despite a lot of effort, it has been difficult to get a clear and consistent overview of what is going on, where the problems are, how long they last for, and what is the impact. This is particularly true for the LHC, where faults may induce long recovery times after being fixed. The AFT project was launched in February 2014 as collaboration between the Controls and Operations groups with stakeholders from the LHC Availability Working Group (AWG). The AFT system has been used successfully in operation for LHC since 2015, yielding a lot of attention and generating a growing user community. In 2017 the scope has been extended to cover the entire Injector Complex. This paper will describe the AFT system and the way it is used in terms of architecture, features, user communities, workflows and added value for the organisation.

TU Darmstadt, Darmstadt, Germany

For the new FAIR accelerator complex at GSI the settings management system LSA is used. It is developed in collaboration with CERN and until now it is executed strictly serial. Nowadays the performance gain of single core processors have nearly stagnated and multicore processors dominate the market. This evolution forces software projects to make use of the parallel hardware to increase their performance. In this thesis LSA is analyzed and parallelized using different parallelization patterns like task and loop parallelization. The most common case of user interaction is to change specific settings so that the accelerator performs at its best. For each changed setting, LSA needs to calculate all child settings of the parameter hierarchy. To maximize the speedup of the calculations, they are also optimized sequentially. The used data structures and algorithms are reviewed to ensure minimal resource usage and maximal compatibility with parallel execution. The overall goal of this thesis is to speed up the calculations so that the results can be shown in a user interface with nearly no noticeable latency.

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.

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.

Timing System at ESS

J. Cereijo García, T. Korhonen, J.H. Lee
ESS, Lund, Sweden

The European Spallation Source (ESS) timing system is based on the hardware developed by Micro-Research Finland (MRF). The main purposes of the timing system are: generation and distribution of synchronous clock signals and trigger events to the facility, providing a time base so that data from different systems can be time-correlated and synchronous transmission of beam-related data for for different subsystems of the facility. The timing system has a tree topology: one Event Generator (EVG) sends the events, clocks and data to an array of Event Receivers (EVRs) through an optical distribution layer (fan-out modules). The event clock frequency for ESS will be 88.0525 MHz, divided down from the bunch frequency of 352.21 MHz. An integer number of ticks of this clock will define the beam macro pulse full length, around 2.86 ms, with a repetition rate of 14 Hz. An active delay compensation mechanism will provide stability against long-term drifts. A novelty of ESS compared to other facilities is the use of the features provided by EVRs in uTCA form factor, such as trigger and clock distribution over the backplane. These EVRs are already being deployed in some systems and test stands.

ESS, Lund, Sweden

The European Spallation Source (ESS) linear accelerator will deliver high energy proton bunches to tungsten sectors on a rotating Target Wheel, which will produce neutrons through a nuclear process. The motion control system of the Target Wheel presents engineering challenges, such as: velocity and phase stability requirements to precisely align individual tungsten sectors with proton bunches from the accelerator; a high moment of inertia due to the composition and distribution of mass on the wheel; limitations on the physical space to integrate control components, and components for associated safety systems; and, some components being exposed to a high radiation environment. The motion control system being prototyped employs components that satisfy the constraints on the physical space and radiation environment. Precise velocity and phasing of the Target Wheel are achieved by generating a series of pulses as each tungsten sector passes a fiducial point in the rotational cycle, and implementing a motion control algorithm to correctly synchronise the Target Wheel with reference signals from the centralised ESS timing system, which also controls the timing of the accelerator.

The ISOLDE facility at CERN requires a wide variety of software applications to ensure maximum productivity. It will be further enforced by two new and innovative applications; Automatic Save After set uP (ASAP) and Fast Beam Investigation (FBI). ASAP saves crucial time for the engineers in charge (EIC) during the physics campaign. It automatizes and standardizes a repetitive process. In addition, for each new set up, the EIC is required to document the settings of all important elements before delivering beam to the users. FBI will be serving two different needs. First, it will be used as a beam traceability tool. The settings of every element of ISOLDE that could obstruct, stop or affect the beam will be tracked by the application. This will allow to understand better the presence of radioactive contaminants after each experiment at every possible point in the facility. The second functionality will allow real time monitoring of the machine status during a physics run. FBI will be the most efficient way to visualize the status of the machine and find the reason that prevents the beam from arriving to the experimental station.

ESO, Garching bei Muenchen, Germany

The Extremely Large Telescope is a 39-metre ground-based telescope being built by ESO. It will be the largest optical/near-infrared telescope in the world and first light is foreseen for 2024. The overall ELT Linux development environment will be presented with an in-depth presentation of its core, the waf build system, and the customizations that ESO is currently developing. The ELT software development for telescopes and instruments poses many challenges to cover the different needs of such a complex system:a variety of technologies, Java, C/C++ and Python as programming languages, Qt5 as the GUI toolkit, communication frameworks such as OPCUA, DDS and ZeroMQ, the interaction with entities such as PLCs and real-time hardware, and users, in-house and not, looking at new usage patterns. All this optimized to be on time for the first light. To meet these requirements, a set of tools was selected. Its content ranges from an IDE, to compilers, interpreters, analysis and debugging tools for the various languages and operations. At the heart of the toolkit lies the modern build framework waf:a versatile tool written in Python selected due to its multiple language support and high performance.

The purpose of the Target Safety System (TSS) is to protect the public from exposure to unsafe levels of radiation, prevent the release of radioactive material beyond permissible limits, and bring the neutron spallation function into a safe state. In order to fulfill the necessary safety functions, the TSS continually monitors critical parameters within target station systems. If any parameter exceeds an acceptable level, the TSS actuates contactors to cut power to components at the front end of the accelerator and prevent the beam from reaching the target. The TSS is classified as a safety structure, system and component, relevant for the safety of the public and the environment. As such, it requires the highest level of rigor in design and quality for interlock systems at the ESS. Standards are applied to provide a guideline for building the TSS architecture and designing in resistance to single failures and common cause failures. This paper describes the system architecture and design of the TSS, including interfaces with target station and accelerator systems, and explains how the design complies with authority conditions and requirements imposed by development standards.

Traditionally, designers of transformer-based beam current monitor diagnostic systems are constrained by fundamental trade-offs when reducing distortion in time-domain beam-pulse facsimile waveforms while also attempting to preserve information in the frequency-domain. When modelling the sensor system with a net-work of linear time-invariant passive components, and a state-based representation based on first-order differential equations, we identify two internal dynamical states isolated from each other by the parasitic resistance in the transformer windings. They are the parasitic capacitance voltage across the transformer's windings, and the transformer inductor current. These states are typically imperfectly observed due to noise, component value variance, and sensor component network topology. We will discuss how feedback-based Kalman State Estimation implemented within digital signal-processing might be employed to reduce negative impacts of noise along with component variance, and how Kalman Estimation might also optimize the conflicting goals of beam-pulse facsimile waveform fidelity together with preservation of fre-quency domain information.

Wall Current Monitor Using PXI and LabVIEW at CERN

The new data acquisition system for the PS ring wall current monitors installed in the PS is able to perform higher frequency measurements of a beam bunch up to a frequency of 2.7 GHz. This is an important improvement, since the oscillating signal within the bandwidth 500-700 MHz, is related to losses of a beam bunch. The losses can be reduced by measuring the frequency and classifying the cause of the oscillations. The PXI-5661 is used to carry out spectral analysis of this signal. The acquisition is performed on a PXI running LabVIEW Real-Time and synchronized using a trigger from the accelerator timing system.

A browser-based graphical user interface has been developed at Diamond. It is known as known as MalcolmJS as it communicates using Diamond's Malcolm Middleware protocol. The original goal was to communicate, via websockets with a PandABox in order to allow a user to examine and set attributes of numerous functional blocks within the instrument. With the continuing maturity of the JavaScript language, in particular the release of ES6, along with the availability of off-the-shelf reactive open-source JavaScript libraries, such as Facebook's React and Node.js, a rich set of tools and frameworks have entered the arena of user interface development suitable for control systems. This paper describes the design decisions based on these tools, experiences and lessons learned during and after the development process and the possibilities for future development as a generic, adaptable framework for instrument and control system user interfaces.

The monochromator is known to be one of the most critical optical elements of a synchrotron beamline. It directly affects the beam quality with respect to energy and position, demanding high stability performance and fine position control. The new high-dynamic double-crystal monochromator (HD-DCM) [1], prototyped at the Brazilian Synchrotron Light Laboratory (LNLS), was designed for the future X-ray undulator and superbend beamlines of Sirius, the new Brazilian 4th generation synchrotron [2]. At this kind of machine, the demand for stability is even higher and conflicts with factors such as high-power loads, power load variation, and vibration sources. To identify and ensure sufficient control of the dynamic behaviour of all subcomponents in the proto-type, an implementation in MATLAB/Simulink Real-Time environment in a Speedgoat Real-Time Perfor-mance Machine was developed. This approach enables rapid prototyping, by allowing a shared environment for system modeling and testing. The tool was developed in a modular architecture aiming at practical model itera-tion and platform migration to standard beamline con-trollers, which can prove portability and scalability fea-tures.

The Laser MegaJoule Facility: Control System Status Report

The Laser MegaJoule (LMJ) is a 176-beam laser facility, located at the CEA CESTA Laboratory near Bordeaux (France). It is designed to deliver about 1.4 MJ of energy to targets, for high energy density physics experiments, including fusion experiments. The first 8-beams bundle was operated in October 2014 and a new bundle was commissioned in October 2016. The next two bundles are on their way. There are three steps for the validation of a new bundle and its integration to the existing control system. The first step is to verify the ability of every command control subsystems to drive the new bundle using a secondary independent supervisory. It is performed from a dedicated integration control room. The second is to switch the bundle to the main operations control room supervisory. At this stage, we perform the global system tests to validate the commissioning of the new bundle. In this paper we focus on the switch of a new bundle from the integration control room to the main operations control room. We have to connect all equipment controllers of the bundle to the operations network and update the Facility Configuration Management.
