	We introduce the control system of the SuperKEKB collider which is based on EPICS. We standardize the CPU module so that we easily maintain our huge control system. Most Input/Output Controllers (IOCs) installed along the 3 km beamline at SuperKEKB are developed with only two kinds of CPU module. In addition to providing standard IOC for individual hardware, we develop some beam operation system which promotes the beam commissioning. The alarm monitoring system, abort trigger system, and Beam Gate system are developed by the control group. The sophisticated Beam Gate system for positron beam controls operation of both damping ring and main ring. It obviously promotes the beam commissioning at those rings. The other highlight is the precisely synchronized control system. It is necessary to realize the highly complicated control of beam injection process. We configure the dedicated network with the Event Timing System and the distributed shared memory. The distant hardware components are synchronously operated with this network. The beam commissioning of SuperKEKB has been started in 2016. The control system supports its fruitful beam operation without serious problem.

MOBPP03	Fault Tolerant, Scalable Middleware Services Based on Spring Boot, REST, H₂ and Infinispan	distributed, database, controls, operation	33
	W. Sliwinski, K. Kaczkowski, W. Zadlo CERN, Geneva, Switzerland
	Control systems require several, core services for work coordination and everyday operation. One such example is Directory Service, which is a central registry of all access points and their physical location in the network. Another example is Authentication Service, which verifies callers identity and issues a signed token, which represents the caller in the distributed communication. Both cases are real life examples of middleware services, which have to be always available and scalable. The paper discusses design decisions and technical background behind these two central services used at CERN. Both services were designed using latest technology standards, namely Spring Boot and REST. Moreover, they had to comply with demanding requirements for fault tolerance and scalability. Therefore, additional extensions were necessary, as distributed in-memory cache (using Apache Infinispan), or Oracle database local mirroring using H₂ database. Additionally, the paper will explain the tradeoffs of different approaches providing high-availability features and lessons learnt from operational usage.

MOBPP04	The ELT M1 Local Control Software: From Requirements to Implementation	controls, PLC, GUI, software	38
	L. Andolfato, J. Argomedo, C. Diaz Cano, R. Frahm, T.R. Grudzien, N. Kornweibel, D. Ribeiro Gomes dos Santos, J. Sagatowski ESO, Garching bei Muenchen, Germany C.M. Silva CSW, Coimbra, Portugal
	This paper presents the ELT M1 Local Control Software. M1 is the 39 m primary mirror of the Extremely Large Telescope composed of 798 hexagonal segments. Each segment can be controlled in piston, tip, and tilt, and provides several types of sensor data, totaling 24000 I/O points. The control algorithm, used to dynamically maintain the alignment and the shape of the mirror, is based on three pipelined stages dedicated to collect the sensors’ measurements, compute new references, and apply them to the actuators. Each stage runs at 500 Hz and the network traffic produced by devices and servers is close to 1.2 million UDP packets/s. The reliability of this large number of devices is improved by the introduction of a failure detection isolation and recovery SW component. The paper summarizes the main SW requirements, presents the architecture based on a variation of the estimator/controller/adapter design pattern, and provides details on the implementation technologies, including the SW platform and the application framework. The lessons learned from deploying the SW on CPUs with different NUMA architectures and from the adoption of different testing strategies are also described.

MOMPL006	Automatic Deployment in a Control System Environment	controls, EPICS, software, target	126
	M.G. Konrad, S. Beher, A.P. Lathrop, D.G. Maxwell, J.P.H. Ryan FRIB, East Lansing, Michigan, USA
	Funding: Work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DE-SC0000661 Development of many software projects at the Facility of Rare Isotope Beams (FRIB) follows an agile development approach. An important part of this practice is to make new software versions available to users frequently to meet their changing needs during commissioning and to get feedback from them in a timely manner. However, building, testing, packaging, and deploying software manually can be a time-consuming and error-prone process. We will present processes and tools used at FRIB to standardize and automate the required steps. We will also describe our experience upgrading control system computers to a new operating system version as well as to a new EPICS release.

MOPHA011	Improving Gesture Recognition with Machine Learning: A Comparison of Traditional Machine Learning and Deep Learning	GUI, real-time, interface, controls	214
	R. Bacher DESY, Hamburg, Germany
	Meaningful gesturing is important for an intuitive human-machine communication. This paper deals with methods suitable for identifying different finger, hand and head movements using supervised machine learning algorithms. On the one hand it discusses an implementation based on the k-nearest neighbor classification algorithm (traditional machine learning approach). On the other hand it demonstrates the classification potential of a convolutional neural network (deep learning approach). Both methods are capable of distinguishing between fast and slow, short and long, up and down, or right and left linear as well as clockwise and counterclockwise circular movements. The details of the different methods with respect to recognition accuracy and performance will be presented.

MOPHA022	Implementation of ISO 50001 Energy Management System With the Advantage of Archive Viewer in NSRRC	controls, instrumentation, SCADA, factory	239
	C.S. Chen, W.S. Chan, Y.Y. Cheng, Y.F. Chiu, Y.-C. Chung, K.C. Kuo, M.T. Lee, Y.-C. Lin, C.Y. Liu, Z.-D. Tsai NSRRC, Hsinchu, Taiwan
	Due to the limited energy resources in Taiwan, energy conservation is always a big issue for everyone who lives in this country. According to the data from the related departments, nearly 98% of energy is imported from abroad for more than a decade. Despite the strong dependency on foreign fuel imports, the energy subsidy policy leads to a relatively low cost of energy for end users, while it is not reasonable. In order to resolve the energy resource shortage and pursue a more efficient energy use, the implementation of ISO 50001 energy management system is activated with the advantage of the Archive Viewer in NSRRC this year. The energy management system will build up a overall energy usage model and several energy performance indicators to help us achieve efficient energy usage.

MOPHA033	Timing, Synchronization and Software-Generated Beam Control at FRIB	timing, hardware, software, controls	272
	E. Daykin, M.G. Konrad FRIB, East Lansing, Michigan, USA
	Funding: Work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DE-SC0000661 The Facility for Rare Isotope Beams, once completed, will require hundreds of devices throughout the machine to operate using synchronized timestamps and triggering events. These include, but are not limited to fault timestamps, time-dependent diagnostic measurements and complex beam pulse patterns. To achieve this design goal, we utilize a timing network using off-the-shelf hardware from Micro Research Finland. A GPS time base is also utilized to provide client timestamping synchronization via NTP/PTP. We describe our methods for software-generated event and beam pulse patterns, performance of installed equipment against project requirements, integration with other systems and challenges encountered during development.

MOPHA043	Accelerator Control Data Mining with WEKA	controls, target, database, GUI	293
	W. Fu, K.A. Brown, T. D’Ottavio, P.S. Dyer, S. Nemesure BNL, Upton, New York, USA
	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-SC0012704 with the U.S. Department of Energy. Accelerator control systems generates and stores many time-series data related to the performance of an accelerator and its support systems. Many of these time series data have detectable change trends and patterns. Being able to timely detect and recognize these data change trends and patterns, analyse and predict the future data changes can provide intelligent ways to improve the controls system with proactive feedback/forward actions. With the help of advanced data mining and machine learning technology, these types of analyses become easier to produce. As machine learning technology matures with the inclusion of powerful model algorithms, data processing tools, and visualization libraries in different programming languages (e.g. Python, R, Java, etc), it becomes relatively easy for developers to learn and apply machine learning technology to online accelerator control system data. This paper explores time series data analysis and forecasting in the Relativistic Heavy Ion Collider (RHIC) control systems with the Waikato Environment for Knowledge Analysis (WEKA) system and its Java data mining APIs.

MOPHA044	Development of Ethernet Based Real-Time Applications in Linux Using DPDK	Linux, feedback, Ethernet, real-time	297
	G. Gaio, G. Scalamera Elettra-Sincrotrone Trieste S.C.p.A., Basovizza, Italy
	In the last decade Ethernet has become the most popular way to interface hardware devices and instruments to the control system. Lower cost per connection, reuse of existing network infrastructures, very high data rates, good noise rejection over long cables and finally an easier maintainability of the software in the long term are the main reasons of its success. In addition, the need of low latency systems of the High Frequency Trading community has boosted the development of new strategies, such as CPU isolation, to run real-time applications in plain Linux with a determinism of the order of microseconds. DPDK (Data Plane Development Kit), an open source software solution mainly sponsored by Intel, addresses the request of high determinism over Ethernet by bypassing the network stack of Linux and providing a more friendly framework to develop tasks which are even able to saturate a 100 Gbit connection. Benchmarks regarding the real-time performance and preliminary results of employing DPDK in the acquisition of beam position monitors for the fast orbit feedback of the Elettra storage ring will be presented.

MOPHA045	A New Simulation Stucture to Improve Software Dependability in Collider-Accelerator Control Systems	simulation, controls, framework, factory	301
	Y. Gao, T.G. Robertazzi Stony Brook University, Stony Brook, New York, USA K.A. Brown, J. Morris, R.H. Olsen BNL, Upton, New York, USA
	In this work, we propose a new simulation framework aiming to improve the robustness of the control system. It focuses on enhancing the reliability of controls ADO codes by running user-customized testing. The new simulation architecture has two independent parts; together they cover a large amount of ADOs frequently used by developers. The first part of the simulation framework focuses on testing ADOs with GPIB connections to devices. It consists of several function blocks and has a switch mechanism which enables users to conveniently turn on and off the simulation mode without changing the ADO codes. Moreover, it contains a special module which automates testing on ADO codes. Testing results are summarized and presented to users for codes analysis. The second part of the framework adopts a totally different structure. It simulates a different type of interface. Specifically, it focuses on testing ADOs with Ethernet connections to devices. It is based on a powerful networking engine called Twisted, which is an event-driven network programming framework developed by the Twisted Matrix Labs. The simulation framework can handle multiple types of devices at the same time.

MOPHA051	Towards Specification of Tango V10	TANGO, controls, CORBA, framework	331

	Funding: Tango Community More than 40 laboratories use Tango Controls as a framework for their control systems. During its 18 years of existence, Tango Controls has evolved and matured. The latest 9.3.3 release is regarded as the most stable and feature-reach version of the framework. However, it makes use of already outdated CORBA technology which impacts all the stack, from the low-level transport protocol up to the client API and tools. The Tango Community decided to move forward and is preparing for so-called Tango Controls v10. Tango v10 is meant to be more a new implementation of the framework than a release of new features. The new implementation shall make the code easier to maintain and extend as well as remove legacy technologies. At the same time, it shall keep the Tango Controls objective philosophy and allows the new implementation to coexist with the old one at the same laboratory. The first step in the process is to provide a formal specification of current concepts and protocol. This specification will be base for the development and verification of new source code. Formal specification of Tango Controls and its purpose will be presented along with used tools and methodologies.

MOPHA067	New Injection Information Archiver for SuperKEKB	injection, linac, operation, EPICS	370
	H. Kaji KEK, Ibaraki, Japan
	We upgraded the Injection Archiver System of the SuperKEKB collider. It records the information related with the beam injection. The system is configured on the EPICS network. The database server employs Archiver Appliance as the database management system. In addition, the distributed shared memory is installed on the database server. Its memory area is synchronized with other nodes such as bunch current monitor via the optical connection. Therefore the database server can collect the data like bunch current at the RF-bucket which the beam pulse is injected. By using this dedicated optical network, we succeed the high-speed and stable data acquisition. The injection data can be recorded, pulse-by-pulse, in 50 Hz without any packet loss.

MOPHA080	Automatic Reconfiguration of CERN 18 kV Electrical Distribution - the Auto Transfer Control System	controls, operation, PLC, Ethernet	400
	J.C. Letra Simoes, S. Infante, F.A. Marin CERN, Geneva, Switzerland
	Availability is key to electrical power distribution at CERN. The CERN electrical network has been consolidated over the last 15 years in order to cope with the evolving needs of the laboratory and now comprises a 200 MW supply from the French grid at 400 kV, a partial back up from the Swiss grid at 130 kV and 16 diesel generators. The Auto Transfer Control System has a critical role in minimizing the duration of power cuts on this complex electrical network, thus significantly reducing the impact of downtime on CERN accelerator operation. In the event of a major power loss, the control system analyzes the global status of the network and decides how to reconfigure the network from alternative sources, following predefined constraints and priorities. The Auto Transfer Control System is based on redundant logical controllers (PLC) with multiple remote IO stations linked via an Ethernet IP ring (over optical fiber) across the three major substations at CERN. This paper describes the system requirements, constraints and the applicable technologies, which will be used to deliver an operational system by 2020.

	Funding: Supported by the US Department of Energy, Los Alamos National Laboratory. Managed by Triad National Security, LLC, for the DOE National Nuclear Security Administration (Contract 89233218CNA000001). A new capability for conducting explosively-driven dynamic physics experiments at the Proton Radiographic (pRad) facility at Los Alamos National Laboratory (LANL) is in development. The pRad facility, an experimental area of the Los Alamos Neutron Science Center (LANSCE), performs multi frame proton radiography of materials subjected to an explosive process. Under design is a new beamline with confinement and containment vessels and required supporting systems and components. Five distinct vacuum sections have been identified, each equipped with complete vacuum pumping assemblies. Inert gas systems are included for backfill and pressurization and supporting piping integrates the subsystems for gas distribution and venting. This paper will discuss the design of the independent vacuum control subsystems, the integrated vacuum and gas control system and full incorporation into the Experimental Physics and Industrial Control System (EPICS) based LANSCE Control Systems and Networks.

MOPHA113	Linux-based PXIe System for the Real-Time Control of New Painting Bumper at CERN	controls, software, operation, hardware	483
	M.P. Pimentel, E. Carlier, C. Chanavat, T. Gharsa, G. Gräwer, N. Magnin, N. Voumard CERN, Geneva, Switzerland
	In the framework of the LHC Injectors Upgrade Project, the new connection from Linac4, injecting a 160 MeV H⁻ beam into the Proton Synchrotron Booster (PSB) requires a set of four slow kicker magnets (KSW) per PSB ring to move the beam on a stripping foil, remove electrons and perform phase space painting. A new multiple-linear waveform generator based on a Marx topology powers each KSW, allowing adjustment of the current discharge shape with high flexibility for the different beam users. To control these complex power generators, National Instruments (NI) PXIe crates fitted with a set of modules (A/D, D/A, FPGA, PROFINET) are used. Initially, control software developed with LabVIEW has validated the test bench hardware. A full software re-engineering, accessing the hardware using Linux drivers, C APIs and the C++ framework FESA3 under Linux CentOS7 was achieved for operational deployment. This paper describes the hardware used, and the integration of NI PXIe systems into CERN controls environment, as well as the software architecture to access the hardware and provide PSB operators and kicker experts with the required control and supervision.

MOPHA117	Big Data Archiving From Oracle to Hadoop	database, monitoring, operation, SCADA	497
	I. Prieto Barreiro, M. Sobieszek CERN, Meyrin, Switzerland
	The CERN Accelerator Logging Service (CALS) is used to persist data of around 2 million predefined signals coming from heterogeneous sources such as the electricity infrastructure, industrial controls like cryogenics and vacuum, or beam related data. This old Oracle based logging system will be phased out at the end of the LHC’s Long Shut-down 2 (LS2) and will be replaced by the Next CERN Accelerator Logging Service (NXCALS) which is based on Hadoop. As a consequence, the different data sources must be adapted to persist the data in the new logging system. This paper describes the solution implemented to archive into NXCALS the data produced by QPS (Quench Protection System) and SCADAR (Supervisory Control And Data Acquisition Relational database) systems, which generate a total of around 175, 000 values per second. To cope with such a volume of data the new service has to be extremely robust, scalable and fail-safe with guaranteed data delivery and no data loss. The paper also explains how to recover from different failure scenarios like e.g. network disruption and how to manage and monitor this highly distributed service.

MOPHA152	Use of Multi-Network Fieldbus for Integration of Low-Level Intelligent Controller Within Control Architecture of Fast Pulsed System at CERN	controls, interface, Ethernet, FPGA	589
	N. Voumard, C. Boucly, M.P. Pimentel, L. Strobino, P. Van Trappen CERN, Geneva, Switzerland
	Fieldbuses and Industrial Ethernet networks are extensively used for the control of fast-pulsed magnets at CERN. With the ongoing trend to develop increasingly more complex low-level intelligent controllers near to the actuators and sensors, the flexibility to integrate these within different control architectures grows in importance. In order to reduce development efforts and keep the fieldbus choice open, a multi-network field-bus technology has been selected for the network interfacing part of the controllers. Such an approach has been successfully implemented for several projects such as the development of high voltage capacitor chargers/dischargers, the surveillance of floating solid-state switch and the monitoring of a power triggering system that, today, are interfaced either to PROFIBUS-DP or PROFINET networks. The integration of various fieldbus interfaces within the controller and the required embedded software/gateware to manage to network communication are presented. The gain in flexibility, modularity and openness obtained through this approach is also reviewed.

MOPHA154	Data Acquisition System Deployment Using Docker Containers for the SMuRF Project	software, EPICS, timing, hardware	597
	J.A. Vásquez SLAC, Menlo Park, California, USA
	The SLAC Microresonator Radio Frequency (SMuRF) system is being developed as a readout system for next generation Cosmic Microwave Background (CMB) cameras. It is based on a FPGA board where the real-time digital processing algorithms are implemented, and high-level applications running in an industrial PC. The software for this project is based on C++ and Python and it is in active development. The software follows the client-server model where the server implements the low-level communication with the FGPA while high-level applications and data processing algorithms run on the client. SMuRF systems are being deployed in several institutions and in order to facilitate the management of the software application releases, dockers containers are being used. Docker images, for both servers and clients, contain all the software packages and configurations needed for their use. The images are tested, tagged, and published in one place. They can then be deployed in all other institutions in minutes with no extra dependencies.

MOSH1001	Current Status of KURAMA-II	radiation, monitoring, survey, detector	641
	M. Tanigaki Kyoto University, Research Reactor Institute, Osaka, Japan
	KURAMA-II, a successor of a carborne gamma-ray survey system named KURAMA (Kyoto University RAdiation MApping system), has become one of the major systems for the activities related to the nuclear accident at TEPCO Fukushima Daiichi Nuclear Power Plant in 2011. The development of KURAMA-II is still on the way to extend its application areas beyond specialists. One of such activities is the development of cloud services for serving an easy management environment for data management and interactions with existing radiation monitoring schemes. Another trial is to port the system to a single-board computer for serving KURAMA-II as a tool for the prompt establishment of radiation monitoring in a nuclear accident. In this paper, the current status of KURAMA-II on its developments and applications along with some results from its applications are introduced.

TUBPL05	RecSyncETCD: A Fault-tolerant Service for EPICS PV Configuration Data	operation, EPICS, distributed, controls	714
	T. Ashwarya, E.T. Berryman, M.G. Konrad FRIB, East Lansing, Michigan, USA
	Funding: Work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DESC0000661 RecCaster is an EPICS module which is responsible for uploading Process Variables (PVs) metadata from the IOC database to a central server called RecCeiver. The RecCeiver service is a custom-built application that passes this data on to the ChannelFinder, a REST-based search service. Together, RecCaster and RecCeiver form the building blocks of RecSync. RecCeiver is not a distributed service which makes it challenging to ensure high availability and fault-tolerance to its clients. We have implemented a new version of RecCaster which uploads the PV metadata to ETCD. ETCD is a commercial off-the-shelf distributed key-value store intended for high availability data storage and retrieval. It provides fault-tolerance as the service can be replicated on multiple servers to keep data consistently replicated. ETCD is a drop-in replacement for the existing RecCeiver to provide data storage and retrieval for PV metadata. Also, ETCD has a well-documented interface for client operations including the ability to live-watch the PV metadata for its clients. This paper discusses the design and implementation of RecSyncETCD as a fault-tolerant service for storing and retrieving EPICS PV metadata.

TUBPL06	Energy Consumption Monitoring With Graph Databases and Service Oriented Architecture	database, monitoring, operation, interface	719
	A. Kiourkos, S. Infante, K.S. Seintaridis CERN, Meyrin, Switzerland
	CERN is a major electricity consumer. In 2018 it consumed 1.25 TWh, 1/3 the consumption of Geneva. Monitoring of this consumption is crucial for operational reasons but also for raising awareness of the users regarding energy utilization. This monitoring is done via a system, developed internally and is quite popular within the CERN community therefore to accommodate the increasing requirements, a migration is underway that utilizes the latest technologies for data modeling and processing. We present the architecture of the new energy monitoring system with an emphasis on the data modeling, versioning and the use of graphs to store and process the model of the electrical network for the energy calculations. The algorithms that are used are presented and a comparison with the existing system is performed in order to demonstrate the performance improvements and flexibility of the new approach. The system embraces the Service Oriented Architecture principles and we illustrate how these have been applied in its design. The different modules and future possibilities are also presented with an analysis of their strengths, weaknesses, and integration within the CERN infrastructure.

TUBPR01	The Distributed Oscilloscope: A Large-Scale Fully Synchronised Data Acquisition System Over White Rabbit	HOM, distributed, status, controls	725
	D. Lampridis, T. Gingold, M. Malczak, F. Vaga, T. Włostowski, A. Wujek CERN, Geneva, Switzerland M. Malczak Warsaw University of Technology, Institute of Electronic Systems, Warsaw, Poland
	A common need in large scientific experiments is the ability to monitor by means of simultaneous data acquisition across the whole installation. Data is acquired as a result of triggers which may either come from external sources, or from internal triggering of one of the acquisition nodes. However, a problem arises from the fact that once the trigger is generated, it will not arrive to the receiving nodes simultaneously, due to varying distances and environmental conditions. The Distributed Oscilloscope (DO) concept attempts to address this problem by leveraging the sub-nanosecond synchronization and deterministic data delivery provided by White Rabbit (WR) and augmenting it with automatic discovery of acquisition nodes and complex trigger event scheduling, in order to provide the illusion of a virtual oscilloscope. This paper presents the current state of the DO, including work done on the FPGA and software level to enhance existing acquisition hardware, as well as a new protocol based on existing industrial standards. It also includes test results obtained from a demonstrator based on two digitizers separated by a 10 km optical fiber, used as a showcase of the DO concept.

TUBPR03	Major Upgrade of the HIT Accelerator Control System Using PTP and TSN Technology	controls, timing, operation, Ethernet	738
	A. Peters, J.M. Mosthaf, C. Schömers HIT, Heidelberg, Germany
	Two important reasons led to the first developments for a new ACS for the HIT ion therapy accelerator complex: a) the first implementation of the ACS was done in 2003-2005 resulting in well-functioning, but mostly proprietary solutions more and more components of e.g. the specially built device control units (DCUs) are becoming discontinued, thus a new realization using standard SoCs or similar is necessary; b) new functionality like multiple energy operation* should enhance the duty factor of the accelerator facility resulting in significantly higher patient irradiation efficiency. In cooperation with our commercial partner we are investigating the newly available deterministic Ethernet technologies like "Time-Sensitive Networking" with several IEEE 802.1xx standards. Early TSN implementations in embedded controller boards and switches were obtained in a test installation in autumn of 2018 to study feasibility, e.g. the required timing precision using PTP (resp. IEEE 802.1AS-Rev) to realize a "one-wire-ACS" based on Ethernet only for deterministic data transfer and message based triggers for synchronized ACS functions. We will report on our test bench experiences. R. Baer, Status and conceptual design of the control system for … HICAT, ICALEPCS 2005 *M.

TUCPL01	Adding Machine Learning to the Analysis and Optimization Toolsets at the Light Source BESSY II	injection, booster, controls, operation	754
	L. Vera Ramirez, T. Mertens, R. Müller, J. Viefhaus HZB, Berlin, Germany G. Hartmann University of Kassel, Kassel, Germany
	The Helmholtz Association has initiated the implementation of the Data Management and Analysis concept across its centers in Germany. At Helmholtz-Zentrum Berlin, both the beamline and the machine (accelerator) groups have started working towards setting up the infrastructure and tools to introduce modern analysis, optimization, automation and AI techniques for improving the performance of the (large scale) user facility and its experimental setups. This paper focuses on our first steps with Machine Learning techniques over the past months at BESSY II as well as organizational topics and collaborations. The presented results correspond to two complementary scenarios. The first one is based on supervised ML models trained with real accelerator data, whose target are real-time predictions for several measurements (lifetime, efficiency, beam loss, …); some of these techniques are also used for additional tasks such as outlier detection or feature importance analysis. The second scenario includes first prototypes towards self-tuning of machine parameters in different optimization cases (injection efficiency, orbit correction, …) with Deep Reinforcement Learning agents.

TUCPL07	Optimal Control for Rapid Switching of Beam Energies for the ATR Line at BNL	controls, simulation, optics, quadrupole	789
	J.P. Edelen, N.M. Cook RadiaSoft LLC, Boulder, Colorado, USA K.A. Brown, P.S. Dyer BNL, Upton, New York, USA
	Funding: This material is based upon work supported by the U.S. Department of Energy, Office of Science, Office of Nuclear Physics under Award Number DE-SC0019682. The Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory will undergo a beam energy scan over the next several years. To execute this scan, the transfer line between the Alternating Gradient Synchrotron (AGS) and RHIC or the so-called the ATR line, must be re-tuned for each energy. Control of the ATR line has four primary constraints: match the beam trajectory into RHIC, match the transverse focusing, match the dispersion, and minimize losses. Some of these can be handled independently, for example orbit matching. However, offsets in the beam can affect the transverse beam optics, thereby coupling the dynamics. Furthermore, the introduction of vertical optics increases the possibilities for coupling between transverse planes, and the desire to make the line spin transparent further complicates matters. During this talk, we will explore three promising avenues for controlling the ATR line, model predictive control (MPC), on-line optimization methods, and hybrid MPC and optimization methods. We will provide an overview of each method, discuss the tradeoffs between these methods, and summarize our conclusions.

TUDPP01	A Monitoring System for the New ALICE O2 Farm	monitoring, detector, database, controls	835
	G. Vino, D. Elia INFN-Bari, Bari, Italy V. Chibante Barroso, A. Wegrzynek CERN, Meyrin, Switzerland
	The ALICE Experiment has been designed to study the physics of strongly interacting matter with heavy-ion collisions at the CERN LHC. A major upgrade of the detector and computing model (O2, Offline-Online) is currently ongoing. The ALICE O2 farm will consist of almost 1000 nodes enabled to readout and process on-the-fly about 27 Tb/s of raw data. To increase the efficiency of computing farm operations a general-purpose near real-time monitoring system has been developed: it lays on features like high-performance, high-availability, modularity, and open source. The core component (Apache Kafka) ensures high throughput, data pipelines, and fault-tolerant services. Additional monitoring functionality is based on Telegraf as metric collector, Apache Spark for complex aggregation, InfluxDB as time-series database, and Grafana as visualization tool. A logging service based on Elasticsearch stack is also included. The designed system handles metrics coming from operating system, network, custom hardware, and in-house software. A prototype version is currently running at CERN and has been also successfully deployed by the ReCaS Datacenter at INFN Bari for both monitoring and logging.

	The CLARA experiment at the STFC, Daresbury laboratory has just completed its first successful exploitation period. The CLARA controls system is being rapidly deployed as CLARA enters its next development phase and our current infrastructure is becoming hard to maintain. Virtualization of the server infrastructure will allow the rapid deployment, recovery and testing of systems infrastructure. This talk will review our experience of migrating several key services and IOCs to a virtualized environment. KVM and LXD have been evaluated against our current system and Ansible has been used to automate many tasks that were normally done by hand. The Archiver Appliance is being exploited beyond its original deployment and is a critical component of several analysis tool-chains. Virtualization allows development, maintenance and deployment of the archiver without disrupting its users. Virtualization is also used to manage the CLARA Virtual Accelerator. The Virtual Accelerator can now run with many instances proving useful for scientists. Originally, it was limited to one instance per server.

	Funding: This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. As the National Ignition Facility (NIF) enters its second decade of full-scale operations, the demands on all aspects of the Information Technology (IT) infrastructure are becoming more varied, complex, and critical. Cybersecurity is an increasing focus area for the NIF IT team with the goal of securing the data center whilst providing the flexibility for developers to continue to access the sensitive areas of the controls system and the production tools. This must be done whilst supporting the interoperability of controls system elements executing on legacy bare metal hardware in an increasingly homogenized virtual environment in addition to responding to the user’s requests for ever-increasing storage needs and the introduction of cloud services. While addressing these evolutionary changes, the impact to continuous 24/7 Shot Operations must also be minimized. The challenges, strategies and implementation approaches being undertaken by the NIF IT team at the NIF to address the issues of infrastructure modernization will be presented.

WEAPP04	ICS Infrastructure Deployment Overview at ESS	controls, database, interface, framework	875
	B. Bertrand, S. Armanet, J. Christensson, A. Curri, A. Harrisson, R. Mudingay ESS, Lund, Sweden
	The ICS Control Infrastructure group at the European Spallation Source (ESS) is responsible for deploying many different services. We treat Infrastructure as code to deploy everything in a repeatable, reproducible and reliable way. We use three main tools to achieve that: Ansible (an IT automation tool), AWX (a GUI for Ansible) and CSEntry (a custom in-house developed web application used as Configuration Management Database). CSEntry (Control System Entry) is used to register any device with an IP address (network switch, physical machines, virtual machines). It allows us to use it as a dynamic inventory for Ansible. DHCP and DNS are automatically updated as soon as a new host is registered in CSEntry. This is done by triggering a task that calls an Ansible playbook via AWX API. Virtual machines can be created directly from CSEntry with one click, again by calling another Ansible playbook via AWX API. This playbook uses proxmox (our virtualization platform) API for the VM creation. By using Ansible groups, different proxmox clusters can be managed from the same CSEntry web application. Those tools give us an easy and flexible solution to deploy software in a reproducible way.

	C. Diaz Cano, R. Abuter, T.R. Grudzien, N. Kornweibel, J. Sagatowski, H. Tischer ESO, Garching bei Muenchen, Germany
	Funding: E.S.O. This paper presents the development of the Miniscule ELT (MELT) Control Software. MELT is an optical test bench with a turbulence generator, whose main objective is to deploy and validate key functionalities of central control system and the Wavefront control strategies on the Extremely Large Telescope (ELT) during AIV/commissioning and operation phase. The subsystems under control are: a segmented primary mirror, a secondary mirror on a hexapod, an adaptive fourth mirror, a fast tip/tilt mirror, phasing sensor, a light source, a Wavefront sensor, a IR camera, together with their control interfaces that emulate the ELT conditions. The Core Integration Infrastructure will be deployed to MELT for their verification and testing strategy, producing feedback to their requirements and design. This paper describes the Control SW distributed architecture, communication patterns, user interfaces and SW infrastructure. The control algorithms are being developed separately and will be integrated into the control loop via MATLAB scripts. *MELT - An optomechanical emulation testbench for ELT wavefront control and phasing strategy

WEMPL007	EPICS Controlled Wireless Sensors	controls, EPICS, interface, software	1015
	M.T. Rolland Stony Brook University, Computer Science Department, Stony Brook, New York, USA K.J. Gofron BNL, Upton, New York, USA
	At the trade-off of power, wireless technologies are much more portable and convenient than their wired counterparts. This is especially true in the scientific sphere, where many environmental factors must be recorded at all times at as many locations as possible. Using these technologies, scientists can often reduce cost while maximizing the number of sensors without compromising sensor quality. To this end, we have developed EPICS controllers for both Bluetooth Low Energy (BLE) sensors and XBee ZigBee sensors. For BLE, we chose the Nordic Thingy:52 for its low cost, high battery life, and impressive range of sensors. The controller we developed combines EPICS base functions, the Bluetooth generic attribute data structure library, and multithreading techniques to enable real-time broadcast of the Thingy’s 20+ sensors’ live values. Because BLE is limited in range, we also developed a controller for the XBee sensor which, through the ZigBee mesh protocol, can expand its range through each node added into the network. With these controllers, NSLS-II scientists will have access to a whole new class of sensors which are both easier to deploy and cheaper than their wired predecessors.

WEPHA026	Integrating COTS Equipment in the CERN Accelerator Domain	controls, LabView, timing, interface	1136
	O.Ø. Andreassen, C. Charrondière, K. Develle, A. Rijllart, R.E. Rossel, J. Steen, J. Tagg, T. Zilliox CERN, Geneva, Switzerland
	Successful integration of industrial equipment in the CERN accelerator complex relies mainly on 3 key components. The first part is the Controls Middleware (CMW). That provides a common communication infrastructure for the accelerator controls at CERN. The second part is timing. To orchestrate and align electronic and electrical equipment across the 27 km Large Hadron Collider (LHC) at sub nanosecond precision, an elaborate timing scheme is needed. Every component has to be configured and aligned within milliseconds and then trigger in perfect harmony with each other. The third and last bit is configuration management. The COTS devices have to be kept up to date, remotely managed and compatible with each other at all times. This is done through a combination of networked Pre eXecution Environments (PXE) mounting network accessible storage on the front ends, where operating systems and packages can be maintained across systems. In this article we demonstrate how COTS based National Instruments PXI and cRIO systems can be integrated in the CERN accelerator domain for measurement and monitoring systems.

WEPHA027	Evaluation of Timing and Synchronization Techniques on NI CompactRIO Platforms	FPGA, controls, timing, hardware	1141
	O.Ø. Andreassen, C. Charrondière, K. Develle, R.E. Rossel, T. Zilliox CERN, Geneva, Switzerland
	For distributed data acquisition and control system, clock synchronization between devices is key. The internal CPU clock of a CompactRIO has an accuracy of 40 ppm at 25 degree Celsius, which can cause up to 3 sec of drift per day. To compensate for this drift, common practice is to use a central clock (such as NTP) to synchronize the systems. In addition, the cRIO has an onboard FPGA which has its own 40 MHz clock. This clock is not synchronized with the CPU, and will also cause time drift. For short measurements, this drift is usually negligible, but for continuous data acquisition systems, running 24/7, the accumulated error has to be compensated. This article will show how we synchronized all clocks across multiple systems used for monitoring seismic activities in the LHC underground and surface areas. It will also describe the mechanism used to cross check synchronization by using the CERN developed White Rabbit timing system.

WEPHA033	Construction and Implementation of Control and DAQ System of Micro Crystallography (MX) Beamline via Server Virtualization	EPICS, controls, data-acquisition, software	1149
	H.J. Choi, H.S. Kim, S.W. Kim, W.W. Lee PAL, Pohang, Republic of Korea
	The project aimed to implement a beamline control and data collection system through a server virtualization system, and was applied to the 5C beamline of the 3rd generation beamline of Pohang Accelerator Laboratory (PAL). The 5C beamline is currently under construction for the FBDD beamline with the goal of building a fully automated beamline. Therefore, the project was started to operate stably and efficiently various systems to be applied to the beamline. The control system was implemented using EPICS software tools and MxDC/MxLive software for data acquisition and storage. The control and data collection system of this beamline is integrated using XCP-ng[1] (XenServer Based), and it is in operation. With the integrated server virtualization system, network organization / simplification and data send/receive between systems are more stabilized. The overall size of the system has been significantly reduced, making maintenance easier.

WEPHA034	Software Tools for Hardware Elliptical Cavity Simulator Management and Configuration	cavity, controls, EPICS, hardware	1153
	W. Cichalewski, K. Klys TUL-DMCS, Łódź, Poland
	Funding: Work supported by Polish Ministry of Science and Higher Education, decision number DIR/WK/2016/2017/03-1 The European Spallation Source (ESS) is currently in the middle of its construction phase. This facility linear accelerator consists of different sections. Superconducting part of this linac will be equipped with spokes and elliptical cavities (like M-Beta and H-Beta types). Various ESS linac components will be delivered by different in-kind partners from Europe. In order to provide a reliable development and evaluation platform hardware-based electronic cavity simulator have been built. This solution is especially useful for Low Level Radio Frequency (LLRF) systems development and integration in case of limited access to real superconducting structures. This contribution presents software tools developed for efficient cavity simulator parameters configuration and management. Solutions based on Python and EPICS framework are presented. Tool adaptation to ESS proposed E3 framework and experience from cavity simulator operation are also discussed.

WEPHA071	Timing System Integration with MTCA at ESS	timing, EPICS, hardware, linac	1264
	J.J. Jamróz, J. Cereijo García, T. Korhonen, J.H. Lee ESS, Lund, Sweden
	European Spallation Source (ESS) organization has selected cutting-edge technologies to satisfy performance and scalability expectations: - Micro Telecommunications Computing Architecture (MTCA). - Micro Research Finland (MRF) based timing system with delay compensation. - Experimental Physics and Industrial Control System (EPICS). To achieve optimal data acquisition quality, the control system is built on top of the timing system which gives the same absolute time reference to all EPICS process variables (PVs). The MTCA system gives configurable cableless access to manage connections among different electronic mezzanine cards, therefore reducing installation workload.

WEPHA103	Backward Compatible Update of the Timing System of WEST	FPGA, timing, distributed, controls	1338
	Y. Moudden, A. Barbuti, G. Caulier, T. Poirier, B. Santraine, B. Vincent CEA/DRF/IRFM, St Paul Lez Durance, France
	Between 2013 and 2016, the tokamak Tore Supra in operation at Cadarache (CEA-France) since 1988 underwent a major upgrade following which it was renamed WEST (Tungsten [W] Environment in Steady state Tokamak). The synchronization system however was not upgraded since 1999. At the time, a robust design was achieved based on AMD’s TAXI chip: clock and events are distributed from a central emitter over a star shaped network of simplex optical links to electronic crates around the tokamak. Unfortunately, spare boards were not produced in sufficient quantities and the TAXI is obsolete. In fact, multigigabit serial communication standards question the future availability of any such low rate SerDeses. Designing replacement boards provides an opportunity for a new CDR solution and extended functionalities (loss-of-lock detection, latency monitoring). Backward compatibility is a major constraint given the lack of resources for a full upgrade. We will first describe the current state of the timing network of WEST, then the implementation of a custom CDR in full firmware, using the IOSerDeses of Xilinx FPGAs and will finally provide preliminary results on development boards.

WEPHA104	Managing Cybersecurity for Control System Safety System development environments	controls, software, ISOL, monitoring	1343
	R. Mudingay, S. Armanet ESS, Lund, Sweden
	At ESS, we manage cyber security for our control system infrastructure by mixing together technologies that are relevant for each system. User access to the control system networks is controlled by an internal DMZ concept whereby we use standard security tools (vulnerability scanners, central logging, firewall policies, system and network monitoring), and users have to go through dedicated control points (reverse proxy, jump hosts, privileged access management solutions or EPICS channel or PV access gateways). The infrastructure is managed though a DevOps approach: describing each component using a configuration management solution; using version control to track changes, with continuous integration workflows to our development process; and constructing the deployment of the lab/staging area to mimic the production environment. We also believe in the flexibility of visualization. This is particularly true for safety systems where the development of safety-critical code requires a high level of isolation. To this end, we utilize dedicated virtualized infrastructure and isolated development environments to improve control (remote access, software update, safety code management).

WEPHA121	Deep Neural Network for Anomaly Detection in Accelerators	synchrotron, Windows, operation, controls	1375
	M. Piekarski, W.T. Kitka NSRC SOLARIS, Kraków, Poland J. Jaworek-Korjakowska AGH University of Science and Technology, Faculty of Electrical Engineering, Automatics, Computer Science and Biomedical Engineering, Kraków, Poland
	The main goal of NSRC SOLARIS is to provide scientific community with high quality synchrotron light. In order to do this it is essential to monitor subsystems that are responsible for beam stability. In this paper a deep neural network for anomaly detection in time series data is proposed. Base model is a pre-trained, 19-layer convolutional neural network VGG-19. Its task is to identify abnormal status of sensors in certain time step. Each time window is a square matrix so can be treated as an image. Any kind of anomalies in synchrotron’s subsystems may lead to beam loss, affect experiments and in extreme cases can cause damage of the infrastructure, therefore when anomaly is detected operator should receive a warning about possible instability.

WEPHA129	Synchronizing LabVIEW Development and Deployment Environment	software, LabView, controls, framework	1394
	O.Ø. Andreassen, C. Charrondière, M.K. Miskowiec, H. Reymond, A. Rijllart CERN, Geneva, Switzerland
	LabVIEW with its graphical approach is suited for engineers used to design and implement systems based on schematics and designs. Being a graphical language, it can be challenging to keep track of drivers, runtime engines, deployments and configurations since most of the tools on the market aimed towards this are implemented for textual languages. Configuration management is possible in the development environment via version control systems such as perforce, however at CERN and in the open source software development community in general, the tendency is moving towards Git. In this paper we demonstrate how the combination of automated builds, packaging, versioning and consistent deployment can further ease and speed up development, while ensure robustness and coherency across systems. We also show how an in-house built tool called "RADE Installer" synchronizes both development environments and drivers across workstations, empowering graphical development at CERN, by merging the open source toolchains with the workflow of LabVIEW. RADE installer represents definitively a solution for LabVIEW to keep track of drivers, runtime engines, deployments and configurations.

WEPHA131	Evaluation of an SFP Based Test Loop for a Future Upgrade of the Optical Transmission for CERN’s Beam Interlock System	operation, diagnostics, hardware, monitoring	1399
	R. Secondo, M.A. Galilée, J.C. Garnier, C. Martin, I. Romera, A.P. Siemko, J.A. Uythoven CERN, Meyrin, Switzerland
	The Beam Interlock System (BIS) is the backbone of CERN’s machine protection system. The BIS is responsible for relaying the so-called Beam Permit signal, initiating in case of need the controlled removal of the beam by the LHC Beam Dumping System. The Beam Permit is encoded as a specific frequency traveling over a more than 30 km long network of optical fibers all around the LHC ring. The progressive degradation of the optical fibers and the aging of electronics affect the decoding of the Beam Permit, thus potentially resulting in an undesired beam dump event and by this reduce the machine availability. Commercial off-the-shelf SFP transceivers were studied with the aim to improve the performance of the optical transmission of the Beam Permit Network. This paper describes the tests carried out in the LHC accelerator to evaluate the selected SFP transceivers and it reports the results of the test loop reaction time measurements during operation. The use of SFPs to optically transmit safety critical signals is being considered as an interesting option not only for the planned major upgrade of the BIS for the HL-LHC era but also for other protection systems.

WEPHA133	Sirius Diagnostics IOC Deployment Strategy	EPICS, diagnostics, controls, software	1407
	L.M. Russo LNLS, Campinas, Brazil
	Sirius beam diagnostics group is responsible for specifying, designing and developing IOCs for most of the diagnostics in the Booster, Storage Ring and Transport Lines, such as: Screens, Slits, Scrapers, Beam Position Monitors, Tune Measurement, Beam Profile, Current Measurement, Injection Efficiency and Bunch-by-Bunch Feedback. In order to ease maintenance, improve robustness, repeatability and dependency isolation a set of guidelines and recipes were developed for standardizing the IOC deployment. It is based on two main components: containerization, which isolates the IOC in a well-known environment, and a remote boot strategy for our diagnostics servers, which ensures all hosts boot in the same base operating system image. In this paper, the remote boot strategy, along with its constituent parts, as well as the containerization guidelines will be discussed.

WEPHA134	Monitoring System for IT Infrastructure and EPICS Control System at SuperKEKB	EPICS, monitoring, controls, status	1413
	S. Sasaki, T.T. Nakamura KEK, Ibaraki, Japan M. Hirose KIS, Ibaraki, Japan
	The monitoring system has been deployed to efficiently monitor IT infrastructure and EPICS control system at SuperKEKB. The system monitors two types of data: metrics and logs. Metrics such as network traffic and CPU usage are monitored with Zabbix. In addition, we developed an EPICS Channel Access client application that sends PV values to Zabbix server and the status of each IOC is monitored with it. The archived data in Zabbix are visualized on Grafana, which allows us to easily create dashboards and analyze the data. Logs such as text data are monitored with the Elastic Stack, which lets us collect, search, analyze and visualize logs. We apply it to monitor broadcast packets in the control network and the frequency of Channel Access search for each PV. Moreover, a Grafana plugin is developed to visualize the data from pvAccess RPC servers and various data such as CSS alarm status data can be displayed on it.

WEPHA138	Orbit Correction With Machine Learning Techniques at the Synchrotron Light Source DELTA	storage-ring, electron, controls, synchrotron	1426
	D. Schirmer DELTA, Dortmund, Germany
	In the last years, artificial intelligence (AI) has experienced a renaissance in many fields. AI-based concepts are nature-inspired and can also be used in the field of accelerator controls. At DELTA, various studies on this subject were conducted in the past. Among other possible applications, the use of neural networks for automated correction of the electron beam position (orbit control) is of interest. Machine learning (ML) simulations with a DELTA storage ring model were already successful. Recently, conventional Feed-Forward Neural Networks (FFNN) were trained on measured orbits to apply local and global beam position corrections to the 1.5 GeV storage ring DELTA. First experimental results are presented and compared with other orbit control methods.

WEPHA159	Integrating Conventional Facilities Systems via BACnet	EPICS, controls, software, interface	1456
	S.B. Webb ORNL, Oak Ridge, Tennessee, USA
	Funding: This material is based upon work supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under contract number DE-AC05-00OR22725. Conventional facility controls, such as those used for water and cooling systems, are often developed and operated independent of the accelerator control system using commercial SCADA systems. At the Spallation Neutron Source, these systems are fully integrated into the EPICS based machine control system to facilitate optimal machine performance. BACnet is the predominant communication protocol used in the building automation industry, thus inspiring SNS to develop a BACnet/IP software driver for EPICS to enable this integration. This paper describes how SNS uses the BACnet driver and standard EPICS tools to perform custom chiller sequencing to manage chiller system performance and meet accelerator requirements for high availability.

WESH2002	EPICS pva Access Control at ESS	controls, EPICS, software, operation	1509
	G. Weiss ESS, Lund, Sweden
	At the European Spallation Source, PV Access has been selected as the default EPICS protocol. However, PV Access in the initial releases of EPICS 7 does not implement any access control of client requests. In order to be able to protect selected process variables (PVs) from write requests that may cause harm to the system, some type of access control is needed. This paper details how PV Access is extended to partially reuse the access control available in Channel Access, while at the same time providing additional features. It also explains how ESS intends to deploy and manage access control in terms of infrastructure, tools and responsibilities. Limitations of the access control mechanism are also discussed.

THBPP03	Deep Learning Methods on Neutron Scattering Data	scattering, experiment, neutron, detector	1580
	P. Mutti, F. Cecillon, Y. Le Goc, G. Song ILL, Grenoble, France
	Recently, by using deep learning methods, computers are able to surpass or come close to matching human performance on image analysis and pattern recognition. This advanced method could also help interpreting data from neutron scattering experiments. Those data contain rich scientific information about structure and dynamics of materials under investigation, and deep learning could help researchers better understand the link between experimental data and materials properties. We applied deep learning techniques to scientific neutron scattering data. This is a complex problem due to the multi-parameter space we have to deal with. We have used a convolutional neural network-based model to evaluate the quality of experimental neutron scattering images, which can be influenced by instrument configuration, sample and sample environment parameters. Sample structure can be deduced during data collection that can be therefore optimized. The neural network model can predict the experimental parameters to properly setup the instrument and derive the best measurement strategy. This results in a higher quality of data obtained in a shorter time, facilitating data analysis and interpretation.

	Funding: National Synchrotron Light Source, a U.S. Department of Energy (DOE) Office of Science User Facility operated by Brookhaven National Laboratory under Contract No. DE-AC02-98CH10886. PDF beamline is a new addition to Diffraction and In Situ Scattering program. Its state-of-the-art end-station gantry system has two detector stages and one sample environment with 3 m travel rated for 200 kg each. Detectors and environment stages move with 300 mm/s. Linear Brushless DC motors are controlled by Geo Brick LV Delta Tau motor-controller. Stages are equipped with absolute encoders and proximity sensors to avoid collisions. Control system slows the stages down when proximity switches are activated and moves 300 mm/s otherwise. A complex controls and safety system with many custom features is required to provide the full functionality of the gantry system and to protect equipment and users. An optics condition module located upstream of the gantry system contain beam defining slits, a fast shutter that is synchronized with detector frame rate, an alignment LASER, and an X-ray Energy Calibration System. The controls system of the OCM supports automatic operation of the ECS followed by unexpected beam dumps to recalibrate the X-ray wavelength. This contribution will discuss the details of the control system design, implementation, challenges, and first user experience.

We introduce the control system of the SuperKEKB collider which is based on EPICS. We standardize the CPU module so that we easily maintain our huge control system. Most Input/Output Controllers (IOCs) installed along the 3 km beamline at SuperKEKB are developed with only two kinds of CPU module. In addition to providing standard IOC for individual hardware, we develop some beam operation system which promotes the beam commissioning. The alarm monitoring system, abort trigger system, and Beam Gate system are developed by the control group. The sophisticated Beam Gate system for positron beam controls operation of both damping ring and main ring. It obviously promotes the beam commissioning at those rings. The other highlight is the precisely synchronized control system. It is necessary to realize the highly complicated control of beam injection process. We configure the dedicated network with the Event Timing System and the distributed shared memory. The distant hardware components are synchronously operated with this network. The beam commissioning of SuperKEKB has been started in 2016. The control system supports its fruitful beam operation without serious problem.

Fault Tolerant, Scalable Middleware Services Based on Spring Boot, REST, H₂ and Infinispan

distributed, database, controls, operation

W. Sliwinski, K. Kaczkowski, W. Zadlo
CERN, Geneva, Switzerland

Control systems require several, core services for work coordination and everyday operation. One such example is Directory Service, which is a central registry of all access points and their physical location in the network. Another example is Authentication Service, which verifies callers identity and issues a signed token, which represents the caller in the distributed communication. Both cases are real life examples of middleware services, which have to be always available and scalable. The paper discusses design decisions and technical background behind these two central services used at CERN. Both services were designed using latest technology standards, namely Spring Boot and REST. Moreover, they had to comply with demanding requirements for fault tolerance and scalability. Therefore, additional extensions were necessary, as distributed in-memory cache (using Apache Infinispan), or Oracle database local mirroring using H₂ database. Additionally, the paper will explain the tradeoffs of different approaches providing high-availability features and lessons learnt from operational usage.

This paper presents the ELT M1 Local Control Software. M1 is the 39 m primary mirror of the Extremely Large Telescope composed of 798 hexagonal segments. Each segment can be controlled in piston, tip, and tilt, and provides several types of sensor data, totaling 24000 I/O points. The control algorithm, used to dynamically maintain the alignment and the shape of the mirror, is based on three pipelined stages dedicated to collect the sensors’ measurements, compute new references, and apply them to the actuators. Each stage runs at 500 Hz and the network traffic produced by devices and servers is close to 1.2 million UDP packets/s. The reliability of this large number of devices is improved by the introduction of a failure detection isolation and recovery SW component. The paper summarizes the main SW requirements, presents the architecture based on a variation of the estimator/controller/adapter design pattern, and provides details on the implementation technologies, including the SW platform and the application framework. The lessons learned from deploying the SW on CPUs with different NUMA architectures and from the adoption of different testing strategies are also described.

Development of many software projects at the Facility of Rare Isotope Beams (FRIB) follows an agile development approach. An important part of this practice is to make new software versions available to users frequently to meet their changing needs during commissioning and to get feedback from them in a timely manner. However, building, testing, packaging, and deploying software manually can be a time-consuming and error-prone process. We will present processes and tools used at FRIB to standardize and automate the required steps. We will also describe our experience upgrading control system computers to a new operating system version as well as to a new EPICS release.

DESY, Hamburg, Germany

Meaningful gesturing is important for an intuitive human-machine communication. This paper deals with methods suitable for identifying different finger, hand and head movements using supervised machine learning algorithms. On the one hand it discusses an implementation based on the k-nearest neighbor classification algorithm (traditional machine learning approach). On the other hand it demonstrates the classification potential of a convolutional neural network (deep learning approach). Both methods are capable of distinguishing between fast and slow, short and long, up and down, or right and left linear as well as clockwise and counterclockwise circular movements. The details of the different methods with respect to recognition accuracy and performance will be presented.

Due to the limited energy resources in Taiwan, energy conservation is always a big issue for everyone who lives in this country. According to the data from the related departments, nearly 98% of energy is imported from abroad for more than a decade. Despite the strong dependency on foreign fuel imports, the energy subsidy policy leads to a relatively low cost of energy for end users, while it is not reasonable. In order to resolve the energy resource shortage and pursue a more efficient energy use, the implementation of ISO 50001 energy management system is activated with the advantage of the Archive Viewer in NSRRC this year. The energy management system will build up a overall energy usage model and several energy performance indicators to help us achieve efficient energy usage.

The Facility for Rare Isotope Beams, once completed, will require hundreds of devices throughout the machine to operate using synchronized timestamps and triggering events. These include, but are not limited to fault timestamps, time-dependent diagnostic measurements and complex beam pulse patterns. To achieve this design goal, we utilize a timing network using off-the-shelf hardware from Micro Research Finland. A GPS time base is also utilized to provide client timestamping synchronization via NTP/PTP. We describe our methods for software-generated event and beam pulse patterns, performance of installed equipment against project requirements, integration with other systems and challenges encountered during development.

Accelerator control systems generates and stores many time-series data related to the performance of an accelerator and its support systems. Many of these time series data have detectable change trends and patterns. Being able to timely detect and recognize these data change trends and patterns, analyse and predict the future data changes can provide intelligent ways to improve the controls system with proactive feedback/forward actions. With the help of advanced data mining and machine learning technology, these types of analyses become easier to produce. As machine learning technology matures with the inclusion of powerful model algorithms, data processing tools, and visualization libraries in different programming languages (e.g. Python, R, Java, etc), it becomes relatively easy for developers to learn and apply machine learning technology to online accelerator control system data. This paper explores time series data analysis and forecasting in the Relativistic Heavy Ion Collider (RHIC) control systems with the Waikato Environment for Knowledge Analysis (WEKA) system and its Java data mining APIs.

Elettra-Sincrotrone Trieste S.C.p.A., Basovizza, Italy

In the last decade Ethernet has become the most popular way to interface hardware devices and instruments to the control system. Lower cost per connection, reuse of existing network infrastructures, very high data rates, good noise rejection over long cables and finally an easier maintainability of the software in the long term are the main reasons of its success. In addition, the need of low latency systems of the High Frequency Trading community has boosted the development of new strategies, such as CPU isolation, to run real-time applications in plain Linux with a determinism of the order of microseconds. DPDK (Data Plane Development Kit), an open source software solution mainly sponsored by Intel, addresses the request of high determinism over Ethernet by bypassing the network stack of Linux and providing a more friendly framework to develop tasks which are even able to saturate a 100 Gbit connection. Benchmarks regarding the real-time performance and preliminary results of employing DPDK in the acquisition of beam position monitors for the fast orbit feedback of the Elettra storage ring will be presented.

In this work, we propose a new simulation framework aiming to improve the robustness of the control system. It focuses on enhancing the reliability of controls ADO codes by running user-customized testing. The new simulation architecture has two independent parts; together they cover a large amount of ADOs frequently used by developers. The first part of the simulation framework focuses on testing ADOs with GPIB connections to devices. It consists of several function blocks and has a switch mechanism which enables users to conveniently turn on and off the simulation mode without changing the ADO codes. Moreover, it contains a special module which automates testing on ADO codes. Testing results are summarized and presented to users for codes analysis. The second part of the framework adopts a totally different structure. It simulates a different type of interface. Specifically, it focuses on testing ADOs with Ethernet connections to devices. It is based on a powerful networking engine called Twisted, which is an event-driven network programming framework developed by the Twisted Matrix Labs. The simulation framework can handle multiple types of devices at the same time.

More than 40 laboratories use Tango Controls as a framework for their control systems. During its 18 years of existence, Tango Controls has evolved and matured. The latest 9.3.3 release is regarded as the most stable and feature-reach version of the framework. However, it makes use of already outdated CORBA technology which impacts all the stack, from the low-level transport protocol up to the client API and tools. The Tango Community decided to move forward and is preparing for so-called Tango Controls v10. Tango v10 is meant to be more a new implementation of the framework than a release of new features. The new implementation shall make the code easier to maintain and extend as well as remove legacy technologies. At the same time, it shall keep the Tango Controls objective philosophy and allows the new implementation to coexist with the old one at the same laboratory. The first step in the process is to provide a formal specification of current concepts and protocol. This specification will be base for the development and verification of new source code. Formal specification of Tango Controls and its purpose will be presented along with used tools and methodologies.

We upgraded the Injection Archiver System of the SuperKEKB collider. It records the information related with the beam injection. The system is configured on the EPICS network. The database server employs Archiver Appliance as the database management system. In addition, the distributed shared memory is installed on the database server. Its memory area is synchronized with other nodes such as bunch current monitor via the optical connection. Therefore the database server can collect the data like bunch current at the RF-bucket which the beam pulse is injected. By using this dedicated optical network, we succeed the high-speed and stable data acquisition. The injection data can be recorded, pulse-by-pulse, in 50 Hz without any packet loss.

CERN, Geneva, Switzerland

Availability is key to electrical power distribution at CERN. The CERN electrical network has been consolidated over the last 15 years in order to cope with the evolving needs of the laboratory and now comprises a 200 MW supply from the French grid at 400 kV, a partial back up from the Swiss grid at 130 kV and 16 diesel generators. The Auto Transfer Control System has a critical role in minimizing the duration of power cuts on this complex electrical network, thus significantly reducing the impact of downtime on CERN accelerator operation. In the event of a major power loss, the control system analyzes the global status of the network and decides how to reconfigure the network from alternative sources, following predefined constraints and priorities. The Auto Transfer Control System is based on redundant logical controllers (PLC) with multiple remote IO stations linked via an Ethernet IP ring (over optical fiber) across the three major substations at CERN. This paper describes the system requirements, constraints and the applicable technologies, which will be used to deliver an operational system by 2020.

In the framework of the LHC Injectors Upgrade Project, the new connection from Linac4, injecting a 160 MeV H⁻ beam into the Proton Synchrotron Booster (PSB) requires a set of four slow kicker magnets (KSW) per PSB ring to move the beam on a stripping foil, remove electrons and perform phase space painting. A new multiple-linear waveform generator based on a Marx topology powers each KSW, allowing adjustment of the current discharge shape with high flexibility for the different beam users. To control these complex power generators, National Instruments (NI) PXIe crates fitted with a set of modules (A/D, D/A, FPGA, PROFINET) are used. Initially, control software developed with LabVIEW has validated the test bench hardware. A full software re-engineering, accessing the hardware using Linux drivers, C APIs and the C++ framework FESA3 under Linux CentOS7 was achieved for operational deployment. This paper describes the hardware used, and the integration of NI PXIe systems into CERN controls environment, as well as the software architecture to access the hardware and provide PSB operators and kicker experts with the required control and supervision.

CERN, Meyrin, Switzerland

The CERN Accelerator Logging Service (CALS) is used to persist data of around 2 million predefined signals coming from heterogeneous sources such as the electricity infrastructure, industrial controls like cryogenics and vacuum, or beam related data. This old Oracle based logging system will be phased out at the end of the LHC’s Long Shut-down 2 (LS2) and will be replaced by the Next CERN Accelerator Logging Service (NXCALS) which is based on Hadoop. As a consequence, the different data sources must be adapted to persist the data in the new logging system. This paper describes the solution implemented to archive into NXCALS the data produced by QPS (Quench Protection System) and SCADAR (Supervisory Control And Data Acquisition Relational database) systems, which generate a total of around 175, 000 values per second. To cope with such a volume of data the new service has to be extremely robust, scalable and fail-safe with guaranteed data delivery and no data loss. The paper also explains how to recover from different failure scenarios like e.g. network disruption and how to manage and monitor this highly distributed service.

Fieldbuses and Industrial Ethernet networks are extensively used for the control of fast-pulsed magnets at CERN. With the ongoing trend to develop increasingly more complex low-level intelligent controllers near to the actuators and sensors, the flexibility to integrate these within different control architectures grows in importance. In order to reduce development efforts and keep the fieldbus choice open, a multi-network field-bus technology has been selected for the network interfacing part of the controllers. Such an approach has been successfully implemented for several projects such as the development of high voltage capacitor chargers/dischargers, the surveillance of floating solid-state switch and the monitoring of a power triggering system that, today, are interfaced either to PROFIBUS-DP or PROFINET networks. The integration of various fieldbus interfaces within the controller and the required embedded software/gateware to manage to network communication are presented. The gain in flexibility, modularity and openness obtained through this approach is also reviewed.

The SLAC Microresonator Radio Frequency (SMuRF) system is being developed as a readout system for next generation Cosmic Microwave Background (CMB) cameras*. It is based on a FPGA board where the real-time digital processing algorithms are implemented, and high-level applications running in an industrial PC. The software for this project is based on C++ and Python and it is in active development. The software follows the client-server model where the server implements the low-level communication with the FGPA while high-level applications and data processing algorithms run on the client. SMuRF systems are being deployed in several institutions and in order to facilitate the management of the software application releases, dockers containers are being used. Docker images, for both servers and clients, contain all the software packages and configurations needed for their use. The images are tested, tagged, and published in one place. They can then be deployed in all other institutions in minutes with no extra dependencies. This paper describes how the docker images are designed and build, and how continuous integration tools are used in their release cycle for this project.

KURAMA-II, a successor of a carborne gamma-ray survey system named KURAMA (Kyoto University RAdiation MApping system), has become one of the major systems for the activities related to the nuclear accident at TEPCO Fukushima Daiichi Nuclear Power Plant in 2011. The development of KURAMA-II is still on the way to extend its application areas beyond specialists. One of such activities is the development of cloud services for serving an easy management environment for data management and interactions with existing radiation monitoring schemes. Another trial is to port the system to a single-board computer for serving KURAMA-II as a tool for the prompt establishment of radiation monitoring in a nuclear accident. In this paper, the current status of KURAMA-II on its developments and applications along with some results from its applications are introduced.

RecCaster is an EPICS module which is responsible for uploading Process Variables (PVs) metadata from the IOC database to a central server called RecCeiver. The RecCeiver service is a custom-built application that passes this data on to the ChannelFinder, a REST-based search service. Together, RecCaster and RecCeiver form the building blocks of RecSync. RecCeiver is not a distributed service which makes it challenging to ensure high availability and fault-tolerance to its clients. We have implemented a new version of RecCaster which uploads the PV metadata to ETCD. ETCD is a commercial off-the-shelf distributed key-value store intended for high availability data storage and retrieval. It provides fault-tolerance as the service can be replicated on multiple servers to keep data consistently replicated. ETCD is a drop-in replacement for the existing RecCeiver to provide data storage and retrieval for PV metadata. Also, ETCD has a well-documented interface for client operations including the ability to live-watch the PV metadata for its clients. This paper discusses the design and implementation of RecSyncETCD as a fault-tolerant service for storing and retrieving EPICS PV metadata.

CERN, Meyrin, Switzerland

CERN is a major electricity consumer. In 2018 it consumed 1.25 TWh, 1/3 the consumption of Geneva. Monitoring of this consumption is crucial for operational reasons but also for raising awareness of the users regarding energy utilization. This monitoring is done via a system, developed internally and is quite popular within the CERN community therefore to accommodate the increasing requirements, a migration is underway that utilizes the latest technologies for data modeling and processing. We present the architecture of the new energy monitoring system with an emphasis on the data modeling, versioning and the use of graphs to store and process the model of the electrical network for the energy calculations. The algorithms that are used are presented and a comparison with the existing system is performed in order to demonstrate the performance improvements and flexibility of the new approach. The system embraces the Service Oriented Architecture principles and we illustrate how these have been applied in its design. The different modules and future possibilities are also presented with an analysis of their strengths, weaknesses, and integration within the CERN infrastructure.

A common need in large scientific experiments is the ability to monitor by means of simultaneous data acquisition across the whole installation. Data is acquired as a result of triggers which may either come from external sources, or from internal triggering of one of the acquisition nodes. However, a problem arises from the fact that once the trigger is generated, it will not arrive to the receiving nodes simultaneously, due to varying distances and environmental conditions. The Distributed Oscilloscope (DO) concept attempts to address this problem by leveraging the sub-nanosecond synchronization and deterministic data delivery provided by White Rabbit (WR) and augmenting it with automatic discovery of acquisition nodes and complex trigger event scheduling, in order to provide the illusion of a virtual oscilloscope. This paper presents the current state of the DO, including work done on the FPGA and software level to enhance existing acquisition hardware, as well as a new protocol based on existing industrial standards. It also includes test results obtained from a demonstrator based on two digitizers separated by a 10 km optical fiber, used as a showcase of the DO concept.

Major Upgrade of the HIT Accelerator Control System Using PTP and TSN Technology

controls, timing, operation, Ethernet

738

HIT, Heidelberg, Germany

Two important reasons led to the first developments for a new ACS for the HIT ion therapy accelerator complex: a) the first implementation of the ACS was done in 2003-2005 resulting in well-functioning, but mostly proprietary solutions more and more components of e.g. the specially built device control units (DCUs*) are becoming discontinued, thus a new realization using standard SoCs or similar is necessary; b) new functionality like multiple energy operation** should enhance the duty factor of the accelerator facility resulting in significantly higher patient irradiation efficiency. In cooperation with our commercial partner we are investigating the newly available deterministic Ethernet technologies like "Time-Sensitive Networking" with several IEEE 802.1xx standards. Early TSN implementations in embedded controller boards and switches were obtained in a test installation in autumn of 2018 to study feasibility, e.g. the required timing precision using PTP (resp. IEEE 802.1AS-Rev) to realize a "one-wire-ACS" based on Ethernet only for deterministic data transfer and message based triggers for synchronized ACS functions. We will report on our test bench experiences.

The Helmholtz Association has initiated the implementation of the Data Management and Analysis concept across its centers in Germany. At Helmholtz-Zentrum Berlin, both the beamline and the machine (accelerator) groups have started working towards setting up the infrastructure and tools to introduce modern analysis, optimization, automation and AI techniques for improving the performance of the (large scale) user facility and its experimental setups. This paper focuses on our first steps with Machine Learning techniques over the past months at BESSY II as well as organizational topics and collaborations. The presented results correspond to two complementary scenarios. The first one is based on supervised ML models trained with real accelerator data, whose target are real-time predictions for several measurements (lifetime, efficiency, beam loss, …); some of these techniques are also used for additional tasks such as outlier detection or feature importance analysis. The second scenario includes first prototypes towards self-tuning of machine parameters in different optimization cases (injection efficiency, orbit correction, …) with Deep Reinforcement Learning agents.

The Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory will undergo a beam energy scan over the next several years. To execute this scan, the transfer line between the Alternating Gradient Synchrotron (AGS) and RHIC or the so-called the ATR line, must be re-tuned for each energy. Control of the ATR line has four primary constraints: match the beam trajectory into RHIC, match the transverse focusing, match the dispersion, and minimize losses. Some of these can be handled independently, for example orbit matching. However, offsets in the beam can affect the transverse beam optics, thereby coupling the dynamics. Furthermore, the introduction of vertical optics increases the possibilities for coupling between transverse planes, and the desire to make the line spin transparent further complicates matters. During this talk, we will explore three promising avenues for controlling the ATR line, model predictive control (MPC), on-line optimization methods, and hybrid MPC and optimization methods. We will provide an overview of each method, discuss the tradeoffs between these methods, and summarize our conclusions.

The ALICE Experiment has been designed to study the physics of strongly interacting matter with heavy-ion collisions at the CERN LHC. A major upgrade of the detector and computing model (O2, Offline-Online) is currently ongoing. The ALICE O2 farm will consist of almost 1000 nodes enabled to readout and process on-the-fly about 27 Tb/s of raw data. To increase the efficiency of computing farm operations a general-purpose near real-time monitoring system has been developed: it lays on features like high-performance, high-availability, modularity, and open source. The core component (Apache Kafka) ensures high throughput, data pipelines, and fault-tolerant services. Additional monitoring functionality is based on Telegraf as metric collector, Apache Spark for complex aggregation, InfluxDB as time-series database, and Grafana as visualization tool. A logging service based on Elasticsearch stack is also included. The designed system handles metrics coming from operating system, network, custom hardware, and in-house software. A prototype version is currently running at CERN and has been also successfully deployed by the ReCaS Datacenter at INFN Bari for both monitoring and logging.

The CLARA experiment at the STFC, Daresbury laboratory has just completed its first successful exploitation period. The CLARA controls system is being rapidly deployed as CLARA enters its next development phase and our current infrastructure is becoming hard to maintain. Virtualization of the server infrastructure will allow the rapid deployment, recovery and testing of systems infrastructure. This talk will review our experience of migrating several key services and IOCs to a virtualized environment. KVM and LXD have been evaluated against our current system and Ansible has been used to automate many tasks that were normally done by hand. The Archiver Appliance is being exploited beyond its original deployment and is a critical component of several analysis tool-chains. Virtualization allows development, maintenance and deployment of the archiver without disrupting its users. Virtualization is also used to manage the CLARA Virtual Accelerator. The Virtual Accelerator can now run with many instances proving useful for scientists. Originally, it was limited to one instance per server.

As the National Ignition Facility (NIF) enters its second decade of full-scale operations, the demands on all aspects of the Information Technology (IT) infrastructure are becoming more varied, complex, and critical. Cybersecurity is an increasing focus area for the NIF IT team with the goal of securing the data center whilst providing the flexibility for developers to continue to access the sensitive areas of the controls system and the production tools. This must be done whilst supporting the interoperability of controls system elements executing on legacy bare metal hardware in an increasingly homogenized virtual environment in addition to responding to the user’s requests for ever-increasing storage needs and the introduction of cloud services. While addressing these evolutionary changes, the impact to continuous 24/7 Shot Operations must also be minimized. The challenges, strategies and implementation approaches being undertaken by the NIF IT team at the NIF to address the issues of infrastructure modernization will be presented.

ESS, Lund, Sweden

The ICS Control Infrastructure group at the European Spallation Source (ESS) is responsible for deploying many different services. We treat Infrastructure as code to deploy everything in a repeatable, reproducible and reliable way. We use three main tools to achieve that: Ansible (an IT automation tool), AWX (a GUI for Ansible) and CSEntry (a custom in-house developed web application used as Configuration Management Database). CSEntry (Control System Entry) is used to register any device with an IP address (network switch, physical machines, virtual machines). It allows us to use it as a dynamic inventory for Ansible. DHCP and DNS are automatically updated as soon as a new host is registered in CSEntry. This is done by triggering a task that calls an Ansible playbook via AWX API. Virtual machines can be created directly from CSEntry with one click, again by calling another Ansible playbook via AWX API. This playbook uses proxmox (our virtualization platform) API for the VM creation. By using Ansible groups, different proxmox clusters can be managed from the same CSEntry web application. Those tools give us an easy and flexible solution to deploy software in a reproducible way.

The integration of structured data and the PV Access network protocol into the EPICS toolkit has opened up many possibilities for added functionality and features, which more and more facilities are looking to leverage. At the same time however the core developers also have to cope with technical debt incurred in the race to deliver working software. This paper will describe the current status of EPICS 7, and some of the work done in the last two years following the reorganization of the code-base. It will cover some of the development group’s technical and process changes, and echo questions being asked about support for recent language standards that may affect support for older target platforms, and adoption of other internal standards for coding and documentation.

This paper presents the development of the Miniscule ELT (MELT) Control Software. MELT is an optical test bench with a turbulence generator, whose main objective is to deploy and validate key functionalities of central control system and the Wavefront control strategies on the Extremely Large Telescope (ELT) during AIV/commissioning and operation phase. The subsystems under control are: a segmented primary mirror, a secondary mirror on a hexapod, an adaptive fourth mirror, a fast tip/tilt mirror, phasing sensor, a light source, a Wavefront sensor, a IR camera, together with their control interfaces that emulate the ELT conditions. The Core Integration Infrastructure will be deployed to MELT for their verification and testing strategy, producing feedback to their requirements and design. This paper describes the Control SW distributed architecture, communication patterns, user interfaces and SW infrastructure. The control algorithms are being developed separately and will be integrated into the control loop via MATLAB scripts.

At the trade-off of power, wireless technologies are much more portable and convenient than their wired counterparts. This is especially true in the scientific sphere, where many environmental factors must be recorded at all times at as many locations as possible. Using these technologies, scientists can often reduce cost while maximizing the number of sensors without compromising sensor quality. To this end, we have developed EPICS controllers for both Bluetooth Low Energy (BLE) sensors and XBee ZigBee sensors. For BLE, we chose the Nordic Thingy:52 for its low cost, high battery life, and impressive range of sensors. The controller we developed combines EPICS base functions, the Bluetooth generic attribute data structure library, and multithreading techniques to enable real-time broadcast of the Thingy’s 20+ sensors’ live values. Because BLE is limited in range, we also developed a controller for the XBee sensor which, through the ZigBee mesh protocol, can expand its range through each node added into the network. With these controllers, NSLS-II scientists will have access to a whole new class of sensors which are both easier to deploy and cheaper than their wired predecessors.

Successful integration of industrial equipment in the CERN accelerator complex relies mainly on 3 key components. The first part is the Controls Middleware (CMW). That provides a common communication infrastructure for the accelerator controls at CERN. The second part is timing. To orchestrate and align electronic and electrical equipment across the 27 km Large Hadron Collider (LHC) at sub nanosecond precision, an elaborate timing scheme is needed. Every component has to be configured and aligned within milliseconds and then trigger in perfect harmony with each other. The third and last bit is configuration management. The COTS devices have to be kept up to date, remotely managed and compatible with each other at all times. This is done through a combination of networked Pre eXecution Environments (PXE) mounting network accessible storage on the front ends, where operating systems and packages can be maintained across systems. In this article we demonstrate how COTS based National Instruments PXI and cRIO systems can be integrated in the CERN accelerator domain for measurement and monitoring systems.

Evaluation of Timing and Synchronization Techniques on NI CompactRIO Platforms

CERN, Geneva, Switzerland

For distributed data acquisition and control system, clock synchronization between devices is key. The internal CPU clock of a CompactRIO has an accuracy of 40 ppm at 25 degree Celsius, which can cause up to 3 sec of drift per day. To compensate for this drift, common practice is to use a central clock (such as NTP) to synchronize the systems. In addition, the cRIO has an onboard FPGA which has its own 40 MHz clock. This clock is not synchronized with the CPU, and will also cause time drift. For short measurements, this drift is usually negligible, but for continuous data acquisition systems, running 24/7, the accumulated error has to be compensated. This article will show how we synchronized all clocks across multiple systems used for monitoring seismic activities in the LHC underground and surface areas. It will also describe the mechanism used to cross check synchronization by using the CERN developed White Rabbit timing system.

The project aimed to implement a beamline control and data collection system through a server virtualization system, and was applied to the 5C beamline of the 3rd generation beamline of Pohang Accelerator Laboratory (PAL). The 5C beamline is currently under construction for the FBDD beamline with the goal of building a fully automated beamline. Therefore, the project was started to operate stably and efficiently various systems to be applied to the beamline. The control system was implemented using EPICS software tools and MxDC/MxLive software for data acquisition and storage. The control and data collection system of this beamline is integrated using XCP-ng[1] (XenServer Based), and it is in operation. With the integrated server virtualization system, network organization / simplification and data send/receive between systems are more stabilized. The overall size of the system has been significantly reduced, making maintenance easier.

Superconducting part of this linac will be equipped with spokes and elliptical cavities (like M-Beta and H-Beta types). Various ESS linac components will be delivered by different in-kind partners from Europe. In order to provide a reliable development and evaluation platform hardware-based electronic cavity simulator have been built. This solution is especially useful for Low Level Radio Frequency (LLRF) systems development and integration in case of limited access to real superconducting structures. This contribution presents software tools developed for efficient cavity simulator parameters configuration and management. Solutions based on Python and EPICS framework are presented. Tool adaptation to ESS proposed E3 framework and experience from cavity simulator operation are also discussed.

Between 2013 and 2016, the tokamak Tore Supra in operation at Cadarache (CEA-France) since 1988 underwent a major upgrade following which it was renamed WEST (Tungsten [W] Environment in Steady state Tokamak). The synchronization system however was not upgraded since 1999*. At the time, a robust design was achieved based on AMD’s TAXI chip**: clock and events are distributed from a central emitter over a star shaped network of simplex optical links to electronic crates around the tokamak. Unfortunately, spare boards were not produced in sufficient quantities and the TAXI is obsolete. In fact, multigigabit serial communication standards question the future availability of any such low rate SerDeses. Designing replacement boards provides an opportunity for a new CDR solution and extended functionalities (loss-of-lock detection, latency monitoring). Backward compatibility is a major constraint given the lack of resources for a full upgrade. We will first describe the current state of the timing network of WEST, then the implementation of a custom CDR in full firmware, using the IOSerDeses of Xilinx FPGAs and will finally provide preliminary results on development boards.

Managing Cybersecurity for Control System Safety System development environments

ESS, Lund, Sweden

At ESS, we manage cyber security for our control system infrastructure by mixing together technologies that are relevant for each system. User access to the control system networks is controlled by an internal DMZ concept whereby we use standard security tools (vulnerability scanners, central logging, firewall policies, system and network monitoring), and users have to go through dedicated control points (reverse proxy, jump hosts, privileged access management solutions or EPICS channel or PV access gateways). The infrastructure is managed though a DevOps approach: describing each component using a configuration management solution; using version control to track changes, with continuous integration workflows to our development process; and constructing the deployment of the lab/staging area to mimic the production environment. We also believe in the flexibility of visualization. This is particularly true for safety systems where the development of safety-critical code requires a high level of isolation. To this end, we utilize dedicated virtualized infrastructure and isolated development environments to improve control (remote access, software update, safety code management).

The main goal of NSRC SOLARIS is to provide scientific community with high quality synchrotron light. In order to do this it is essential to monitor subsystems that are responsible for beam stability. In this paper a deep neural network for anomaly detection in time series data is proposed. Base model is a pre-trained, 19-layer convolutional neural network VGG-19. Its task is to identify abnormal status of sensors in certain time step. Each time window is a square matrix so can be treated as an image. Any kind of anomalies in synchrotron’s subsystems may lead to beam loss, affect experiments and in extreme cases can cause damage of the infrastructure, therefore when anomaly is detected operator should receive a warning about possible instability.

LabVIEW with its graphical approach is suited for engineers used to design and implement systems based on schematics and designs. Being a graphical language, it can be challenging to keep track of drivers, runtime engines, deployments and configurations since most of the tools on the market aimed towards this are implemented for textual languages. Configuration management is possible in the development environment via version control systems such as perforce, however at CERN and in the open source software development community in general, the tendency is moving towards Git. In this paper we demonstrate how the combination of automated builds, packaging, versioning and consistent deployment can further ease and speed up development, while ensure robustness and coherency across systems. We also show how an in-house built tool called "RADE Installer" synchronizes both development environments and drivers across workstations, empowering graphical development at CERN, by merging the open source toolchains with the workflow of LabVIEW. RADE installer represents definitively a solution for LabVIEW to keep track of drivers, runtime engines, deployments and configurations.

The Beam Interlock System (BIS) is the backbone of CERN’s machine protection system. The BIS is responsible for relaying the so-called Beam Permit signal, initiating in case of need the controlled removal of the beam by the LHC Beam Dumping System. The Beam Permit is encoded as a specific frequency traveling over a more than 30 km long network of optical fibers all around the LHC ring. The progressive degradation of the optical fibers and the aging of electronics affect the decoding of the Beam Permit, thus potentially resulting in an undesired beam dump event and by this reduce the machine availability. Commercial off-the-shelf SFP transceivers were studied with the aim to improve the performance of the optical transmission of the Beam Permit Network. This paper describes the tests carried out in the LHC accelerator to evaluate the selected SFP transceivers and it reports the results of the test loop reaction time measurements during operation. The use of SFPs to optically transmit safety critical signals is being considered as an interesting option not only for the planned major upgrade of the BIS for the HL-LHC era but also for other protection systems.

Sirius beam diagnostics group is responsible for specifying, designing and developing IOCs for most of the diagnostics in the Booster, Storage Ring and Transport Lines, such as: Screens, Slits, Scrapers, Beam Position Monitors, Tune Measurement, Beam Profile, Current Measurement, Injection Efficiency and Bunch-by-Bunch Feedback. In order to ease maintenance, improve robustness, repeatability and dependency isolation a set of guidelines and recipes were developed for standardizing the IOC deployment. It is based on two main components: containerization, which isolates the IOC in a well-known environment, and a remote boot strategy for our diagnostics servers, which ensures all hosts boot in the same base operating system image. In this paper, the remote boot strategy, along with its constituent parts, as well as the containerization guidelines will be discussed.

The monitoring system has been deployed to efficiently monitor IT infrastructure and EPICS control system at SuperKEKB. The system monitors two types of data: metrics and logs. Metrics such as network traffic and CPU usage are monitored with Zabbix. In addition, we developed an EPICS Channel Access client application that sends PV values to Zabbix server and the status of each IOC is monitored with it. The archived data in Zabbix are visualized on Grafana, which allows us to easily create dashboards and analyze the data. Logs such as text data are monitored with the Elastic Stack, which lets us collect, search, analyze and visualize logs. We apply it to monitor broadcast packets in the control network and the frequency of Channel Access search for each PV. Moreover, a Grafana plugin is developed to visualize the data from pvAccess RPC servers and various data such as CSS alarm status data can be displayed on it.

DELTA, Dortmund, Germany

In the last years, artificial intelligence (AI) has experienced a renaissance in many fields. AI-based concepts are nature-inspired and can also be used in the field of accelerator controls. At DELTA, various studies on this subject were conducted in the past. Among other possible applications, the use of neural networks for automated correction of the electron beam position (orbit control) is of interest. Machine learning (ML) simulations with a DELTA storage ring model were already successful. Recently, conventional Feed-Forward Neural Networks (FFNN) were trained on measured orbits to apply local and global beam position corrections to the 1.5 GeV storage ring DELTA. First experimental results are presented and compared with other orbit control methods.

Funding: This material is based upon work supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under contract number DE-AC05-00OR22725.
Conventional facility controls, such as those used for water and cooling systems, are often developed and operated independent of the accelerator control system using commercial SCADA systems. At the Spallation Neutron Source, these systems are fully integrated into the EPICS based machine control system to facilitate optimal machine performance. BACnet is the predominant communication protocol used in the building automation industry, thus inspiring SNS to develop a BACnet/IP software driver for EPICS to enable this integration. This paper describes how SNS uses the BACnet driver and standard EPICS tools to perform custom chiller sequencing to manage chiller system performance and meet accelerator requirements for high availability.

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

At the European Spallation Source, PV Access has been selected as the default EPICS protocol. However, PV Access in the initial releases of EPICS 7 does not implement any access control of client requests. In order to be able to protect selected process variables (PVs) from write requests that may cause harm to the system, some type of access control is needed. This paper details how PV Access is extended to partially reuse the access control available in Channel Access, while at the same time providing additional features. It also explains how ESS intends to deploy and manage access control in terms of infrastructure, tools and responsibilities. Limitations of the access control mechanism are also discussed.

Recently, by using deep learning methods, computers are able to surpass or come close to matching human performance on image analysis and pattern recognition. This advanced method could also help interpreting data from neutron scattering experiments. Those data contain rich scientific information about structure and dynamics of materials under investigation, and deep learning could help researchers better understand the link between experimental data and materials properties. We applied deep learning techniques to scientific neutron scattering data. This is a complex problem due to the multi-parameter space we have to deal with. We have used a convolutional neural network-based model to evaluate the quality of experimental neutron scattering images, which can be influenced by instrument configuration, sample and sample environment parameters. Sample structure can be deduced during data collection that can be therefore optimized. The neural network model can predict the experimental parameters to properly setup the instrument and derive the best measurement strategy. This results in a higher quality of data obtained in a shorter time, facilitating data analysis and interpretation.

PDF beamline is a new addition to Diffraction and In Situ Scattering program. Its state-of-the-art end-station gantry system has two detector stages and one sample environment with 3 m travel rated for 200 kg each. Detectors and environment stages move with 300 mm/s. Linear Brushless DC motors are controlled by Geo Brick LV Delta Tau motor-controller. Stages are equipped with absolute encoders and proximity sensors to avoid collisions. Control system slows the stages down when proximity switches are activated and moves 300 mm/s otherwise. A complex controls and safety system with many custom features is required to provide the full functionality of the gantry system and to protect equipment and users. An optics condition module located upstream of the gantry system contain beam defining slits, a fast shutter that is synchronized with detector frame rate, an alignment LASER, and an X-ray Energy Calibration System. The controls system of the OCM supports automatic operation of the ECS followed by unexpected beam dumps to recalibrate the X-ray wavelength. This contribution will discuss the details of the control system design, implementation, challenges, and first user experience.
