	The Extremely Large Telescope (ELT) is a 39m optical telescope under construction in the Chilean Atacama desert. The design is based on a five-mirror scheme, incorporating Adaptive Optics (AO). The primary mirror consists of 798 segments with 1.4m diameter. The main control challenges can be identified in the number of sensors (~25000) and actuators (~15000) to be coordinated, the computing performance and small latency required for phasing of the primary mirror and the AO. We focus on the design and implementation of the supervisory systems and control strategies. This includes a real time computing (RTC) toolkit to support the implementation of the AO for telescope and instruments. We will also report on the progress done in the implementation of the control software infrastructure necessary for development, testing and integration. We identify a few lessons learned in the past years of development and major challenges for the coming phases of the project.

MOBL02	Real-Time Framework for ITER Control Systems	controls, plasma, framework, operation	45

	The ITER Real-Time Framework (RTF) is a middleware providing common services and capabilities to build real-time control applications in ITER such as the Plasma Control System (PCS) and plasma diagnostics. The RTF dynamically constructs applications at runtime from the configuration. The principal building blocks that compose an application process are called Function Blocks (FB), which follow a modular structure pattern. The application configuration defines the information that can influence control behavior, such as the connections among FBs, their corresponding parameters, and event handlers. The consecutive pipeline process in a busy-waiting mode and a data-driven pattern minimizes jitter and hardens the deterministic system behavior. In contrast, infrastructural capabilities are managed differently in the service layer using non-real-time threads. The deployment configuration covers the final placement of a program instance and thread allocation to the appropriate computing infrastructure. In this paper, we will introduce the architecture and design patterns of the framework as well as the real-life examples used to benchmark the RTF.

MOPV020	Digitisation of the Analogue Waveform System at ISIS	controls, Linux, timing, diagnostics	169
	W.A. Frank, B.R. Aljamal, R.A. Washington STFC/RAL/ISIS, Chilton, Didcot, Oxon, United Kingdom
	Funding: UKRI/STFC The Analogue Waveform System (AWS) at the ISIS Neutron and Muon Source is a distributed system that allows operators to select and monitor analogue waveforms from equipment throughout the facility on oscilloscopes in the Main Control Room (MCR). These signals originate from key accelerator systems in the linear accelerator and synchrotron such as the ion source, magnets, beam diagnostics, and radio frequency (RF) systems. Historical data for ISIS is available on the control system for many relevant channels. However, at present, to avoid disrupting the oscilloscope displays in the MCR, only an hourly image capture of the AWS waveforms is stored. This is largely inadequate for potential data-intensive applications such as anomaly detection, predictive maintenance, post-mortem analysis, or (semi-)automated machine setup, optimization, and control. To address this, a new digital data acquisition (DAQ) system is under development based on the principle of large channel count, simultaneous DAQ. This paper details the proposed architecture of the system and the results of initial prototyping, testing, and commissioning.

MOPV032	Design of a Component-Oriented Distributed Data Integration Model	controls, software, TANGO, distributed	202
	Z. Ni, L. Li, J. Liu, J. Luo, X. Zhou CAEP, Sichuan, People’s Republic of China
	The control system of large scientific facilities is composed of several heterogeneous control systems. As time goes by, the facilities need to be continuously upgraded and the control system also needs to be upgraded. This is a challenge for the integration of complex and large-scale heterogeneous systems. This article describes the design of a data integration model based on component technology, software middleware(The Apache Thrift) and real-time database. The realization of this model shields the relevant details of the software middleware, encapsulates the remote data acquisition as a local function operation, realizes the combination of data and complex calculations through scripts, and can be assembled into new components. The Apache Thrift software framework, for scalable cross-language services development, combines a software stack with a code generation engine to build services that work efficiently.

MOPV035	Development of Alarm and Monitoring System Using Smartphone	EPICS, status, monitoring, network	214
	W.S. Cho PAL, Pohang, Republic of Korea
	In order to find out the problem of the device remotely, we aimed to develop a new alarm system. The main functions of the alarm system are real-time monitoring of EPICS PV data, data storage, and data storage when an alarm occurs. In addition, an alarm is transmitted in real time through an app on the smartphone to communicate the situation to machine engineers of PLS-II. This system uses InfluxDB to store data. In addition, a new program written in Java language was developed so that data acquisition, analysis, and beam dump conditions can be known. furthermore Vue.js is used to develop together with node.js and web-based android and iOS-based smart phone applications, and user interface is serviced. Eventually, using this system, we were able to check the cause analysis and data in real time when an alarm occurs. In this paper, we introduce the design of an alarm system and the transmission of alarms to an application.

MOPV045	Data-Centric Web Infrastructure for CERN Radiation and Environmental Protection Monitoring	controls, SCADA, radiation, framework	261
	A. Ledeul, C.C. Chiriac, G. Segura, J. Sznajd, G. de la Cruz CERN, Meyrin, Switzerland
	Supervision, Control and Data Acquisition (SCADA) systems generate large amounts of data over time. Analyzing collected data is essential to discover useful information, prevent failures, and generate reports. Facilitating access to data is of utmost importance to exploit the information generated by SCADA systems. CERN’s occupational Health & Safety and Environmental protection (HSE) Unit operates a web infrastructure allowing users of the Radiation and Environment Monitoring Unified Supervision (REMUS) to visualize and extract near-real-time and historical data from desktop and mobile devices. This application, REMUS Web, collects and combines data from multiple sources and presents it to the users in a format suitable for analysis. The web application and the SCADA system can operate independently thanks to a data-centric, loosely coupled architecture. They are connected through common data sources such as the open-source streaming platform Apache Kafka and Oracle Rdb. This paper describes the benefits of providing a feature-rich web application as a complement to control systems. Moreover, it details the underlying architecture of the solution and its capabilities.

TUPV033	Distributed Transactions in CERN’s Accelerator Control System	MMI, controls, hardware, distributed	468
	F. Hoguin, S. Deghaye, R. Gorbonosov, J. Lauener, P. Mantion CERN, Geneva, Switzerland
	Devices in CERN’s accelerator complex are controlled through individual requests, which change settings atomically on single Devices. Individual Devices are therefore controlled transactionally. Operators often need to apply a set of changes which affect multiple devices. This is achieved by sending requests in parallel, in a minimum amount of time. However, if a request fails, the Control system ends up in an undefined state, and recovering is a time-consuming task. Furthermore, the lack of synchronisation in the application of new settings may lead to the degradation of the beam characteristics, because of settings being partially applied. To address these issues, a protocol was developed to support distributed transactions and commit synchronisation in the CERN Control system, which was then implemented in CERN’s real-time frameworks. We describe what this protocol intends to solve and its limitations. We also delve into the real-time framework implementation and how developers can benefit from the 2-phase commit to leverage hardware features such as double buffering, and from the commit synchronisation allowing settings to be changed safely while the accelerator is operational.

WEPV033	Architecture of a Multi-Channel Data Streaming Device with an FPGA as a Coprocessor	FPGA, timing, controls, hardware	724
	J.M. Nogiec, P. Thompson Fermilab, Batavia, Illinois, USA
	Funding: This work was supported by the U.S. Department of Energy, Office of Science, Office of High Energy Physics The design of a data acquisition system often involves the integration of a Field Programmable Gate Array (FPGA) with analog front-end components to achieve precise timing and control. Reuse of these hardware systems can be difficult since they need to be tightly coupled to the communications interface and timing requirements of the specific ADC used. A hybrid design exploring the use of FPGA as a coprocessor to a traditional CPU in a dataflow architecture is presented. Reduction in the volume of data and gradual transitioning of data processing away from a hard real-time environment are both discussed. Chief design concerns, including data throughput and precise synchronization with external stimuli, are addressed. The discussion is illustrated by the implementation of a multi-channel digital integrator, a device based entirely on commercial off-the-shelf (COTS) equipment.

	T.C. Shen, A. Sepulveda ALMA Observatory, Santiago, Chile R.A. Augsburger, S.A. Carrasco, P. Galeas, F. Huenupan, R.S. Seguel Universidad de La Frontera, Temuco, Chile
	The ALMA Observatory was inaugurated in 2013, after the 8 years of successful operation, obsolescence has started to emerge in different areas. One of the most critical areas is the control bus of the hardware devices located the antenna, which is based on a customized version of CAN bus. Initial studies were performed to explore alternatives, and one of the candidates could be a solution based on EtherCAT. In this paper, the existing architecture will be presented and new architecture will be proposed, which would not only be compatible with the existing hardware devices but also allow prepared the ground for new subsystems that come with ALMA 2030 initiatives. This document reports the progress achieved in a proof of concept project that explores the possibility to embed the existing ALMA monitor & control data structure into EtherCAT frames and use EtherCAT as the main communication protocol to control hardware devices in all the subsystems that comprise the ALMA telescope.

THPV006	Design of Real-Time Alarm System for CAFe	interface, controls, status, monitoring	867
	N. Xie, Y.H. Guo, B.J. Wang, R. Wang IMP/CAS, Lanzhou, People’s Republic of China
	In accelerator control, the alarm system is a very im-portant real-time monitoring and control system. In order to find specific failures of accelerator-related equipment in time, improve the high availability of the equipment, and ensure the long-term operation of the accelerator. An accelerator alarm system based on Kafka was designed and built on the CAFe. The system uses Phoebus for ar-chitecture deployment. Kafka is used as the streaming platform of the alarm system, which effectively improves the throughput of the system and realizes real-time alarms. In order to realize the function of remote monitor-ing of data in the central control room, CS-Studio is used to draw the opi interface to deploy to the enterprise WeChat platform to realize remote data monitoring. This system greatly improves the response speed of fault han-dling and saves a lot of valuable time for accelerator fault handling.

FRBL03	A Literature Review on the Efforts Made for Employing Machine Learning in Synchrotrons	synchrotron, experiment, software, electron	1039

	Using machine learning (ML) in various contexts is in-creasing due to advantages such as automation for every-thing, trends and pattern identification, highly error-prone, and continuous improvement. Even non-computer experts are trying to learn simple programming languages like Python to implement ML models on their data. De-spite the growing trend towards ML, no study has re-viewed the efforts made on using ML in synchrotrons to our knowledge. Therefore, we are examining the efforts made to use ML in synchrotrons to achieve benefits like stabilizing the photon beam without the need for manual calibrations of measures that can be achieved by reducing unwanted fluctuations in the widths of the electron beams that prevent experimental noises obscured measurements. Also, the challenges of using ML in synchrotrons and a short synthesis of the reviewed articles were provided. The paper can help related experts have a general famil-iarization regarding ML applications in synchrotrons and encourage the use of ML in various synchrotron practices. In future research, the aim will be to provide a more com-prehensive synthesis with more details on how to use the ML in synchrotrons.

FRBR02	An Integrated Data Processing and Management Platform for X-Ray Light Source Operations*	experiment, interface, simulation, GUI	1059
	N.M. Cook, E.G. Carlin, P. Moeller, R. Nagler, B. Nash RadiaSoft LLC, Boulder, Colorado, USA A.M. Barbour, M.S. Rakitin, L. Wiegart 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 Advanced Scientific Computing Research under Award Number DE-SC00215553. The design, execution, and analysis of light source experiments requires the use of increasingly complex simulation, controls and data management tools. Existing workflows require significant specialization to account for beamline-specific operations and pre-processing steps in order to collect and prepare data for more sophisticated analysis. Recent efforts to address these needs at the National Synchrotron Light Source II (NSLS-II) have resulted in the creation of the Bluesky data collection framework, an open-source library providing for experimental control and scientific data collection via high level abstraction of experimental procedures, instrument readouts, and data analysis. We present a prototype data management interface that couples with Bluesky to support guided simulation, measurement, and rapid processing operations. Initial demonstrations illustrate application to coherent X-ray scattering beamlines at the NSLS-II. We then discuss extensions of this interface to permit analysis operations across distributed computing resources, including the use of the Sirepo scientific framework, as well as Jupyter notebooks running on remote computing clusters.

Facilitating access to data is of utmost importance to exploit the information generated by SCADA systems. CERN’s occupational Health & Safety and Environmental protection (HSE) Unit operates a web infrastructure allowing users of the Radiation and Environment Monitoring Unified Supervision (REMUS) to visualize and extract near-real-time and historical data from desktop and mobile devices. This application, REMUS Web, collects and combines data from multiple sources and presents it to the users in a format suitable for analysis. The web application and the SCADA system can operate independently thanks to a data-centric, loosely coupled architecture. They are connected through common data sources such as the open-source streaming platform Apache Kafka and Oracle Rdb. This paper describes the benefits of providing a feature-rich web application as a complement to control systems. Moreover, it details the underlying architecture of the solution and its capabilities.

Devices in CERN’s accelerator complex are controlled through individual requests, which change settings atomically on single Devices. Individual Devices are therefore controlled transactionally. Operators often need to apply a set of changes which affect multiple devices. This is achieved by sending requests in parallel, in a minimum amount of time. However, if a request fails, the Control system ends up in an undefined state, and recovering is a time-consuming task. Furthermore, the lack of synchronisation in the application of new settings may lead to the degradation of the beam characteristics, because of settings being partially applied. To address these issues, a protocol was developed to support distributed transactions and commit synchronisation in the CERN Control system, which was then implemented in CERN’s real-time frameworks. We describe what this protocol intends to solve and its limitations. We also delve into the real-time framework implementation and how developers can benefit from the 2-phase commit to leverage hardware features such as double buffering, and from the commit synchronisation allowing settings to be changed safely while the accelerator is operational.

The design of a data acquisition system often involves the integration of a Field Programmable Gate Array (FPGA) with analog front-end components to achieve precise timing and control. Reuse of these hardware systems can be difficult since they need to be tightly coupled to the communications interface and timing requirements of the specific ADC used. A hybrid design exploring the use of FPGA as a coprocessor to a traditional CPU in a dataflow architecture is presented. Reduction in the volume of data and gradual transitioning of data processing away from a hard real-time environment are both discussed. Chief design concerns, including data throughput and precise synchronization with external stimuli, are addressed. The discussion is illustrated by the implementation of a multi-channel digital integrator, a device based entirely on commercial off-the-shelf (COTS) equipment.

The ALMA Observatory was inaugurated in 2013, after the 8 years of successful operation, obsolescence has started to emerge in different areas. One of the most critical areas is the control bus of the hardware devices located the antenna, which is based on a customized version of CAN bus. Initial studies were performed to explore alternatives, and one of the candidates could be a solution based on EtherCAT. In this paper, the existing architecture will be presented and new architecture will be proposed, which would not only be compatible with the existing hardware devices but also allow prepared the ground for new subsystems that come with ALMA 2030 initiatives. This document reports the progress achieved in a proof of concept project that explores the possibility to embed the existing ALMA monitor & control data structure into EtherCAT frames and use EtherCAT as the main communication protocol to control hardware devices in all the subsystems that comprise the ALMA telescope.

In accelerator control, the alarm system is a very im-portant real-time monitoring and control system. In order to find specific failures of accelerator-related equipment in time, improve the high availability of the equipment, and ensure the long-term operation of the accelerator. An accelerator alarm system based on Kafka was designed and built on the CAFe. The system uses Phoebus for ar-chitecture deployment. Kafka is used as the streaming platform of the alarm system, which effectively improves the throughput of the system and realizes real-time alarms. In order to realize the function of remote monitor-ing of data in the central control room, CS-Studio is used to draw the opi interface to deploy to the enterprise WeChat platform to realize remote data monitoring. This system greatly improves the response speed of fault han-dling and saves a lot of valuable time for accelerator fault handling.

Using machine learning (ML) in various contexts is in-creasing due to advantages such as automation for every-thing, trends and pattern identification, highly error-prone, and continuous improvement. Even non-computer experts are trying to learn simple programming languages like Python to implement ML models on their data. De-spite the growing trend towards ML, no study has re-viewed the efforts made on using ML in synchrotrons to our knowledge. Therefore, we are examining the efforts made to use ML in synchrotrons to achieve benefits like stabilizing the photon beam without the need for manual calibrations of measures that can be achieved by reducing unwanted fluctuations in the widths of the electron beams that prevent experimental noises obscured measurements. Also, the challenges of using ML in synchrotrons and a short synthesis of the reviewed articles were provided. The paper can help related experts have a general famil-iarization regarding ML applications in synchrotrons and encourage the use of ML in various synchrotron practices. In future research, the aim will be to provide a more com-prehensive synthesis with more details on how to use the ML in synchrotrons.

The design, execution, and analysis of light source experiments requires the use of increasingly complex simulation, controls and data management tools. Existing workflows require significant specialization to account for beamline-specific operations and pre-processing steps in order to collect and prepare data for more sophisticated analysis. Recent efforts to address these needs at the National Synchrotron Light Source II (NSLS-II) have resulted in the creation of the Bluesky data collection framework*, an open-source library providing for experimental control and scientific data collection via high level abstraction of experimental procedures, instrument readouts, and data analysis. We present a prototype data management interface that couples with Bluesky to support guided simulation, measurement, and rapid processing operations. Initial demonstrations illustrate application to coherent X-ray scattering beamlines at the NSLS-II. We then discuss extensions of this interface to permit analysis operations across distributed computing resources, including the use of the Sirepo scientific framework, as well as Jupyter notebooks running on remote computing clusters**.
