	W. Zheng, N. Fu, S. Li, Y. Wang, F.Y. Wu, M. Zhang Huazhong University of Science and Technology, State Key Laboratory of Advanced Electromagnetic Engineering and Technology,, Hubei, People’s Republic of China
	EPICS is mature in accelerator community. However, there are endeavors to improve existing control system software like Tango and EPICS 7 mainly driven by the needs of flexibility of the control system and the development of computer technology. This paper presents a new way of building a large experimental device control system using web technology instead of EPICS toolkit. The goal is to improve the interoperability of the control system allowing different component in the control system to talk to each other effortlessly. An abstraction of the control system is made. The control system components are abstracted into resources. The accessing of the resources is done via standard HTTP RESTful web API. HMI is based on HTML and JavaScript in browsers. Web Socket is used for event distribution. The main feature of this design is that all interfaces in the system are based on open web standards, which are interoperable among almost all kinds of devices. The paper also presents a software toolkit to build this kind of control system. A control system for a diagnostic on J-TEXT tokamak built using this toolkit will be presented.

	Funding: Horizon2020 Marie Skłodowska-Curie Grant Agreement No 675265 The Italian National Hadrontherapy Center (CNAO) is a particle treatment and research center equipped with a synchrotron accelerator. The configuration and support environment of CNAO’s control system, originally designed in 2003, is currently being upgraded to incorporate mobile devices. As part of the technological upgrade, a product line architecture has been designed with intent to define application scope, reusability of core assets, and specification of variation points. Implementation and compliance with the product line architecture aims at reducing application’s development time, improving reliability, and aiding medical certification procedures. However, definition and compliance with the architecture comes with considerable overhead development costs. In order to assist the development of new environment applications, a visual wizard has been developed to create customized base applications. This paper presents the challenges encountered and description of the product line architecture for the upgraded configuration and support environment. Alongside, we also describe the Wizard Generator, currently implemented applications, and planned application validation.

MOPHA023	Applications of an EPICS Embedded and Credit-card Sized Waveform Acquisition	EPICS, controls, database, operation	242
	Y.-S. Cheng, K.T. Hsu, K.H. Hu, D. Lee, C.Y. Liao, C.Y. Wu NSRRC, Hsinchu, Taiwan
	To eliminate long distance cabling for improving signal quality, the remote waveform access supports have been developed for the TPS (Taiwan Photon Source) and TLS (Taiwan Light Source) control systems for routine operation. The previous mechanism was that a dedicated EPICS IOC has been used to communicate with the present Ethernet-based oscilloscopes to acquire each waveform data. To obtain higher reliability operation and low power consumption, the FPGA and SoC (System-on-Chip) based waveform acquisition which embedded an EPICS IOC has been adopted to capture the waveform signals and process to the EPICS PVs (Process Variables). According to specific purposes use, the different graphical applications have been designed and integrated into the existing operation interfaces. These are convenient to observe waveform status and to analyse the caught data on the control consoles. The efforts are described at this paper.

MOPHA026	Development of an Online Diagnostic Toolkit for the UPC Control System	EPICS, diagnostics, controls, toolkit	246
	H.Z. Chen, Y.-S. Cheng, K.T. Hsu, K.H. Hu, C.Y. Liao, C.Y. Wu NSRRC, Hsinchu, Taiwan
	Most IOC (Input Output Controller) platforms and servers at the TPS control system have been connected to uninterruptible power supplies (UPS) to prevent short downtime of the mains electricity. To accomplish higher availability, it is necessary to maintain batteries and circuits for the UPS system periodically. Thus, an online diagnostic toolkit had to be developed to monitor the status of the UPS system and to notify which abnormal components should be replaced. One dedicated EPICS IOC has been implemented to communicate with each UPS device via SNMP. The PV states of the UPS system are published and archived and specific graphical applications are designed to show the existing control environment via EPICS CA (Channel Access). This paper reports the development of an online diagnostic toolkit for the UPS System.

	NICA (Nuclotron-based Ion Collider fAcility) is a new accelerator complex designed at the Joint Institute for Nuclear Research (Dubna, Russia) to study properties of dense baryonic matter. BM@N (Baryonic Matter at Nuclotron) is the first experiment at the complex. It is an experimental setup in the fixed-target hall of the Nuclotron to perform a research program focused on the production of strange matter in heavy-ion collisions. MPD (Multipurpose Detector) is a detector for colliding beam experiments at the complex, and it is being developed to provide: efficient registration of the particles produced by heavy ion collisions; identification of particle type, charge and energy; reconstruction of vertices of primary interactions and the position of secondary particle production. Existing Slow Control Systems for BM@N experiment, assembling, and testing zones of MPD detectors are based on Tango Controls. They provide monitoring and control of diverse hardware for efficient data taking, stable operation of detectors and quality control of assembled modules. Current status and developments as well as future design and plans for MPD Slow Control System will be reported.

MOPHA085	CERN Controls Open Source Monitoring System	monitoring, controls, software, database	404
	F. Locci, F. Ehm, L. Gallerani, J. Lauener, J.P. Palluel, R. Voirin CERN, Meyrin, Switzerland
	The CERN accelerator controls infrastructure spans several thousands of machines and devices used for Accelerator control and data acquisition. In 2009 a full home-made CERN solution has been developed (DIAMON) to monitor and diagnose the complete controls infrastructure. The adoption of the solution by an enlarged community of users and its rapid expansion led to a final product that became more difficult to operate and maintain, in particular because of the multiplicity and redundancy of the services, the centralized management of the data acquisition and visualization software, the complex configuration and also the intrinsic scalability limits. At the end 2017, a complete new monitoring system for the beam controls infrastructure was launched. The new "COSMOS" system was developed with two main objectives in mind: First, detect instabilities and prevent breakdowns of the control system infrastructure and to provide users with a more coherent and efficient solution for the development of their specific data monitoring agents and related dashboards. This paper describes the overall architecture of COSMOS, focusing on the conceptual and technological choices of the system.

Schwanke Humboldt University Berlin, Institut für Physik, Berlin, Germany J. Schwarz INAF-Osservatorio Astronomico di Brera, Merate, Italy
	The Cherenkov Telescope Array (CTA) will be the next generation ground-based observatory for gamma-ray astronomy at very-high energies. CTA will consist of two large arrays with 118 Cherenkov telescopes in total, deployed in Paranal (Chile) and Roque de Los Muchachos Observatories (Canary Islands, Spain). The Array Control and Data Acquisition (ACADA) system provides the means to execute observations and to handle the acquisition of scientific data in CTA. The Resource Manager & Central Control (RM&CC) sub-system is a core element in the ACADA system. It implements the execution of observation requests received from the scheduler sub-system and provides infrastructure services concerning the administration of various resources to all ACADA sub-systems. The RM&CC is also responsible of the dynamic allocation and management of concurrent operations of up to nine telescope sub-arrays, which are logical groupings of individual CTA telescopes performing coordinated scientific operations. This contribution presents a summary of the main RM&CC design features, and of the future plans for prototyping.

MOPHA149	Accelerator Schedule Management at CERN	controls, operation, software, database	579
	B. Urbaniec, C. Roderick CERN, Geneva, Switzerland
	Maximizing the efficiency of operating CERN’s accelerator complex requires careful forward planning, and synchronized scheduling of cross-accelerator events. These schedules are of interest to many people helping them to plan and organize their work. Therefore, this data should be easily accessible, both interactively and programmatically. Development of the Accelerator Schedule Management (ASM) system started in 2017 to address such topics and enable definition, management and publication of schedule data in generic way. The ASM system currently includes three core modules to manage: Yearly accelerator schedules for the CERN Injector complex and LHC; Submission and scheduling of Machine Development (MD) requests with supporting statistics; Submission, approval, scheduling and follow-up of control system changes and their impact. This paper describes the ASM Web application (built with Angular, TypeScript and Java) in terms of: Core scheduling functionality; Integration of external data sources; Provision of programmatic access to schedule data via a language agnostic REST API (allowing other systems to leverage schedule data).

TUBPR01	The Distributed Oscilloscope: A Large-Scale Fully Synchronised Data Acquisition System Over White Rabbit	network, HOM, distributed, 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.

TUCPR04	Improving User Experience in Complex Systems	interface, experiment, software, neutron	812
	M.J. Clarke, G.C. Murphy, R. Nørager, T.S. Richter ESS, Copenhagen, Denmark
	Don Norman and Jakob Nielsen* define User Experience (UX) as "encompassing all aspects of the end-user’s interaction with the company, its services, and its products". The question is, however, is it possible to provide a significantly better UX in an inherently complex environment, such as at a neutron beamline instrument? With this in mind, we decided to ask the professionals at Design Psykology** to see what might be achievable for user-facing scientific software at the ESS. During a series of short workshops, we looked at general UX principles and how they could be applied to two of our user-facing software projects. We learned a number of useful practices and ideas, such as: why UX is more than just the graphical user interface; the value of creating user personas and mapping their workflow; How to design for the user’s "System 1". A bad UX may make the user feel like they are fighting against the system rather than working with it. A good UX, however, will unobtrusively help them do what they need to do without fuss or bother. If done well, UX is not a zero-sum game: improvements can be made so novices and experts alike can work more efficiently. https://www.nngroup.com/articles/definition-user-experience/ *https://www.designpsykologi.dk/

WEPHA047	Cable Database at ESS	database, interface, controls, operation	1199
	R.N. Fernandes, S.R. Gysin, J.A. Persson, S. Regnell ESS, Lund, Sweden L.J.G. Johansson OTIF, Malmö, Sweden S. Sah Cosylab, Ljubljana, Slovenia M. Salmič COSYLAB, Control System Laboratory, Ljubljana, Slovenia
	When completed, the European Spallation Source (ESS) will have around half a million of installed cables to power and control both the machine and end-stations instruments. To keep track of all these cables throughout the different phases of ESS, an application called Cable Database was developed at the Integrated Control System (ICS) Division. It provides a web-based graphical interface where authorized users may perform CRUD operations in cables, as well as batch imports (through well-defined EXCEL files) to substantially shortened the time needed to deal with massive amounts of cables at once. Besides cables, the Cable Database manages cable types, connectors, manufacturers and routing points, thus fully handling the information that surrounds cables. Additionally, it provides a programmatic interface through RESTful services that other ICS applications (e.g. CCDB) may consume to successfully perform their domain specific businesses. The present paper introduces the Cable Database and describes its features, architecture and technology stack, data concepts and interfaces. Finally, it enumerates development directions that could be pursued to further improve this application.

WEPHA083	ophyd Devices: Imposing Hierarchy on the Flat EPICS V3 Namespace	EPICS, detector, interface, controls	1284
	K.R. Lauer SLAC, Menlo Park, California, USA
	Funding: This work was performed in support of the LCLS project at SLAC supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under Contract No. DE-AC02-76SF00515. EPICS V3 provides simple data types accessible over the network through Channel Access identified by a flat process variable (PV) name. This flexibility is often regarded as a strength of EPICS, as the user can easily pick and choose the information they require. However, such data is almost always inter-related in some manner, pushing the burden of reconstructing that relationship to the end-user/client. ophyd represents hardware in Python as hierarchical classes, grouping together related signals from the underlying control system. ophyd devices make imposing this hierarchy simple, readable, and descriptive. This structure allows ophyd to provide a consistent interface across a wide-range of devices, which can then be used by higher-level software for any number of tasks: from command-line inspection, to scanning/data collection (bluesky), or even automatic GUI generation (typhon, adviewer). ophyd contains a number of pre-built devices for common hardware (and IOCs) as well as the tools to build custom devices.

WEPHA134	Monitoring System for IT Infrastructure and EPICS Control System at SuperKEKB	EPICS, monitoring, network, controls	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.

WEPHA136	The Software-Based Machine Protection System Using EPICS in J-PARC MR	EPICS, operation, controls, GUI	1418

	In J-PARC, a Machine Protection System (MPS) stops accelerator beam operation automatically when an interlock signal comes. Normal MPS accepts interlock signals by hard-wire, but a software-based MPS, called "Soft-MPS", uses only EPICS PVs without wiring. A PLC controller running Linux was introduced to watch at some EPICS PVs over Ethernet, and outputs Soft-MPS signals to the MPS unit after logical calculates. There are 2 reasons of using Soft-MPS. (1) To install interlock signals rapidly. This type of Soft-MPS will switch to hard-wire later. (2) To use non-hardware parameters: for example, machine operation modes, beam bunch information, etc. From the first Soft-MPS setup in 2018 spring, 9 Soft-MPS signals are currently used. As more Soft-MPS signals are expected in the future, we need to discuss the policy.

WEPHA164	CAFlux: A New EPICS Channel Archiver System	EPICS, MMI, database, interface	1470
	K. Xu LANL, Los Alamos, New Mexico, USA
	We post a new EPICS channel archiver system that is being developed at LANSCE of Los Alamos National Laboratory. Different from the legacy archiver system, this system is built on InfluxDB database and Plotly visualization toolkits. InfluxDB is an opensource time series database system and provides a SQL-like language for fast storage and retrieval of time series data. By replacing the old archiving engine and index file with InfluxDB, we have a more robust, compact and stable archiving server. On a client side, we introduce a new implementation combined with asynchronous programming and multithreaded programming. We also describe a web-based archiver configuration system that is associated with our current IRMIS system. To visualize the data stored, we use the JavaScript Plotly graphing library, another open source toolkit for time series data, to build frontend pages. In addition, we also develop a viewer application with more functionality including basic data statistics and simple arithmetic for channel values. Finally, we propose some ideas to integrate more statistical analysis into this system.

	The Cryogenic Near Infrared Spectropolarimeter (Cryo-NIRSP) will be one of the first light instruments on the Daniel K. Inouye Solar Telescope (DKIST) currently under construction in Hawaii. Cyro-NIRSP is a near- and thermal- IR imager and spectrograph operating in a cryogenic environment. It will be used to study the faint solar coronal magnetic field across a large field-of-view. Such a complex and precise instrument demands equal requirements from the control system. The control system must handle the many sub-components (e.g. cameras, polarimeter, mirrors) and bring them all together to manage the setup, timings, synchronization, real time motion and overall monitoring. It is built within the pre-defined DKIST software framework, which provides consistency across all instruments. This paper will discuss how such a control system has been achieved for the Cryo-NIRSP instrument detailing some of the challenges that were overcome relating to the synchronization of specific components and the complex inter-dependencies between configurables. It will also touch on the data processing and visualization software development for the end-to-end functioning of the instrument.

THCPL06	Introducing Big Data Analysis in a Proton Therapy Facility to Reduce Technical Downtime	proton, controls, interlocks, EPICS	1608
	P. Fernandez Carmona, Z. Chowdhuri, S.G. Ebner, F. Gagnon-Moisan, M. Grossmann, J. Snuverink, D.C. Weber PSI, Villigen PSI, Switzerland
	At the center for Proton Therapy of the Paul Scherrer Institute about 450 cancer patients are treated yearly using accelerated protons in three treatment areas. The facility is active since 1984 and for each patient we keep detailed log files containing machine measurements during each fraction of the treatment, which we analyze daily to guarantee dose and position values within the prescribed tolerances. Furthermore, each control and safety system generates textual log files as well as periodic measurements such as pressure, temperature, beam intensity, magnetic fields or reaction time of components. This adds up currently to approximately 5 GB per day. Downtime of the facility is both inconvenient for patients and staff, as well as financially relevant. This article describes how we have extended our data analysis strategies using machine archived parameters and online measurements to understand interdependencies, to perform preventive maintenance of ageing components and to optimize processes. We have chosen Python to interface, structure and analyze the different data sources in an standardized manner. The online channels have been accessed via an EPICS archiver.

EPICS is mature in accelerator community. However, there are endeavors to improve existing control system software like Tango and EPICS 7 mainly driven by the needs of flexibility of the control system and the development of computer technology. This paper presents a new way of building a large experimental device control system using web technology instead of EPICS toolkit. The goal is to improve the interoperability of the control system allowing different component in the control system to talk to each other effortlessly. An abstraction of the control system is made. The control system components are abstracted into resources. The accessing of the resources is done via standard HTTP RESTful web API. HMI is based on HTML and JavaScript in browsers. Web Socket is used for event distribution. The main feature of this design is that all interfaces in the system are based on open web standards, which are interoperable among almost all kinds of devices. The paper also presents a software toolkit to build this kind of control system. A control system for a diagnostic on J-TEXT tokamak built using this toolkit will be presented.

The Italian National Hadrontherapy Center (CNAO) is a particle treatment and research center equipped with a synchrotron accelerator. The configuration and support environment of CNAO’s control system, originally designed in 2003, is currently being upgraded to incorporate mobile devices. As part of the technological upgrade, a product line architecture has been designed with intent to define application scope, reusability of core assets, and specification of variation points. Implementation and compliance with the product line architecture aims at reducing application’s development time, improving reliability, and aiding medical certification procedures. However, definition and compliance with the architecture comes with considerable overhead development costs. In order to assist the development of new environment applications, a visual wizard has been developed to create customized base applications. This paper presents the challenges encountered and description of the product line architecture for the upgraded configuration and support environment. Alongside, we also describe the Wizard Generator, currently implemented applications, and planned application validation.

To eliminate long distance cabling for improving signal quality, the remote waveform access supports have been developed for the TPS (Taiwan Photon Source) and TLS (Taiwan Light Source) control systems for routine operation. The previous mechanism was that a dedicated EPICS IOC has been used to communicate with the present Ethernet-based oscilloscopes to acquire each waveform data. To obtain higher reliability operation and low power consumption, the FPGA and SoC (System-on-Chip) based waveform acquisition which embedded an EPICS IOC has been adopted to capture the waveform signals and process to the EPICS PVs (Process Variables). According to specific purposes use, the different graphical applications have been designed and integrated into the existing operation interfaces. These are convenient to observe waveform status and to analyse the caught data on the control consoles. The efforts are described at this paper.

Most IOC (Input Output Controller) platforms and servers at the TPS control system have been connected to uninterruptible power supplies (UPS) to prevent short downtime of the mains electricity. To accomplish higher availability, it is necessary to maintain batteries and circuits for the UPS system periodically. Thus, an online diagnostic toolkit had to be developed to monitor the status of the UPS system and to notify which abnormal components should be replaced. One dedicated EPICS IOC has been implemented to communicate with each UPS device via SNMP. The PV states of the UPS system are published and archived and specific graphical applications are designed to show the existing control environment via EPICS CA (Channel Access). This paper reports the development of an online diagnostic toolkit for the UPS System.

NICA (Nuclotron-based Ion Collider fAcility) is a new accelerator complex designed at the Joint Institute for Nuclear Research (Dubna, Russia) to study properties of dense baryonic matter. BM@N (Baryonic Matter at Nuclotron) is the first experiment at the complex. It is an experimental setup in the fixed-target hall of the Nuclotron to perform a research program focused on the production of strange matter in heavy-ion collisions. MPD (Multipurpose Detector) is a detector for colliding beam experiments at the complex, and it is being developed to provide: efficient registration of the particles produced by heavy ion collisions; identification of particle type, charge and energy; reconstruction of vertices of primary interactions and the position of secondary particle production. Existing Slow Control Systems for BM@N experiment, assembling, and testing zones of MPD detectors are based on Tango Controls. They provide monitoring and control of diverse hardware for efficient data taking, stable operation of detectors and quality control of assembled modules. Current status and developments as well as future design and plans for MPD Slow Control System will be reported.

The CERN accelerator controls infrastructure spans several thousands of machines and devices used for Accelerator control and data acquisition. In 2009 a full home-made CERN solution has been developed (DIAMON) to monitor and diagnose the complete controls infrastructure. The adoption of the solution by an enlarged community of users and its rapid expansion led to a final product that became more difficult to operate and maintain, in particular because of the multiplicity and redundancy of the services, the centralized management of the data acquisition and visualization software, the complex configuration and also the intrinsic scalability limits. At the end 2017, a complete new monitoring system for the beam controls infrastructure was launched. The new "COSMOS" system was developed with two main objectives in mind: First, detect instabilities and prevent breakdowns of the control system infrastructure and to provide users with a more coherent and efficient solution for the development of their specific data monitoring agents and related dashboards. This paper describes the overall architecture of COSMOS, focusing on the conceptual and technological choices of the system.

The Cherenkov Telescope Array (CTA) will be the next generation ground-based observatory for gamma-ray astronomy at very-high energies. CTA will consist of two large arrays with 118 Cherenkov telescopes in total, deployed in Paranal (Chile) and Roque de Los Muchachos Observatories (Canary Islands, Spain). The Array Control and Data Acquisition (ACADA) system provides the means to execute observations and to handle the acquisition of scientific data in CTA. The Resource Manager & Central Control (RM&CC) sub-system is a core element in the ACADA system. It implements the execution of observation requests received from the scheduler sub-system and provides infrastructure services concerning the administration of various resources to all ACADA sub-systems. The RM&CC is also responsible of the dynamic allocation and management of concurrent operations of up to nine telescope sub-arrays, which are logical groupings of individual CTA telescopes performing coordinated scientific operations. This contribution presents a summary of the main RM&CC design features, and of the future plans for prototyping.

CERN, Geneva, Switzerland

Maximizing the efficiency of operating CERN’s accelerator complex requires careful forward planning, and synchronized scheduling of cross-accelerator events. These schedules are of interest to many people helping them to plan and organize their work. Therefore, this data should be easily accessible, both interactively and programmatically. Development of the Accelerator Schedule Management (ASM) system started in 2017 to address such topics and enable definition, management and publication of schedule data in generic way. The ASM system currently includes three core modules to manage: Yearly accelerator schedules for the CERN Injector complex and LHC; Submission and scheduling of Machine Development (MD) requests with supporting statistics; Submission, approval, scheduling and follow-up of control system changes and their impact. This paper describes the ASM Web application (built with Angular, TypeScript and Java) in terms of: Core scheduling functionality; Integration of external data sources; Provision of programmatic access to schedule data via a language agnostic REST API (allowing other systems to leverage schedule data).

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.

Improving User Experience in Complex Systems

Don Norman and Jakob Nielsen* define User Experience (UX) as "encompassing all aspects of the end-user’s interaction with the company, its services, and its products". The question is, however, is it possible to provide a significantly better UX in an inherently complex environment, such as at a neutron beamline instrument? With this in mind, we decided to ask the professionals at Design Psykology** to see what might be achievable for user-facing scientific software at the ESS. During a series of short workshops, we looked at general UX principles and how they could be applied to two of our user-facing software projects. We learned a number of useful practices and ideas, such as: why UX is more than just the graphical user interface; the value of creating user personas and mapping their workflow; How to design for the user’s "System 1". A bad UX may make the user feel like they are fighting against the system rather than working with it. A good UX, however, will unobtrusively help them do what they need to do without fuss or bother. If done well, UX is not a zero-sum game: improvements can be made so novices and experts alike can work more efficiently.

When completed, the European Spallation Source (ESS) will have around half a million of installed cables to power and control both the machine and end-stations instruments. To keep track of all these cables throughout the different phases of ESS, an application called Cable Database was developed at the Integrated Control System (ICS) Division. It provides a web-based graphical interface where authorized users may perform CRUD operations in cables, as well as batch imports (through well-defined EXCEL files) to substantially shortened the time needed to deal with massive amounts of cables at once. Besides cables, the Cable Database manages cable types, connectors, manufacturers and routing points, thus fully handling the information that surrounds cables. Additionally, it provides a programmatic interface through RESTful services that other ICS applications (e.g. CCDB) may consume to successfully perform their domain specific businesses. The present paper introduces the Cable Database and describes its features, architecture and technology stack, data concepts and interfaces. Finally, it enumerates development directions that could be pursued to further improve this application.

EPICS V3 provides simple data types accessible over the network through Channel Access identified by a flat process variable (PV) name. This flexibility is often regarded as a strength of EPICS, as the user can easily pick and choose the information they require. However, such data is almost always inter-related in some manner, pushing the burden of reconstructing that relationship to the end-user/client. ophyd represents hardware in Python as hierarchical classes, grouping together related signals from the underlying control system. ophyd devices make imposing this hierarchy simple, readable, and descriptive. This structure allows ophyd to provide a consistent interface across a wide-range of devices, which can then be used by higher-level software for any number of tasks: from command-line inspection, to scanning/data collection (bluesky), or even automatic GUI generation (typhon, adviewer). ophyd contains a number of pre-built devices for common hardware (and IOCs) as well as the tools to build custom devices.

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.

In J-PARC, a Machine Protection System (MPS) stops accelerator beam operation automatically when an interlock signal comes. Normal MPS accepts interlock signals by hard-wire, but a software-based MPS, called "Soft-MPS", uses only EPICS PVs without wiring. A PLC controller running Linux was introduced to watch at some EPICS PVs over Ethernet, and outputs Soft-MPS signals to the MPS unit after logical calculates. There are 2 reasons of using Soft-MPS. (1) To install interlock signals rapidly. This type of Soft-MPS will switch to hard-wire later. (2) To use non-hardware parameters: for example, machine operation modes, beam bunch information, etc. From the first Soft-MPS setup in 2018 spring, 9 Soft-MPS signals are currently used. As more Soft-MPS signals are expected in the future, we need to discuss the policy.

We post a new EPICS channel archiver system that is being developed at LANSCE of Los Alamos National Laboratory. Different from the legacy archiver system, this system is built on InfluxDB database and Plotly visualization toolkits. InfluxDB is an opensource time series database system and provides a SQL-like language for fast storage and retrieval of time series data. By replacing the old archiving engine and index file with InfluxDB, we have a more robust, compact and stable archiving server. On a client side, we introduce a new implementation combined with asynchronous programming and multithreaded programming. We also describe a web-based archiver configuration system that is associated with our current IRMIS system. To visualize the data stored, we use the JavaScript Plotly graphing library, another open source toolkit for time series data, to build frontend pages. In addition, we also develop a viewer application with more functionality including basic data statistics and simple arithmetic for channel values. Finally, we propose some ideas to integrate more statistical analysis into this system.

The Cryogenic Near Infrared Spectropolarimeter (Cryo-NIRSP) will be one of the first light instruments on the Daniel K. Inouye Solar Telescope (DKIST) currently under construction in Hawaii. Cyro-NIRSP is a near- and thermal- IR imager and spectrograph operating in a cryogenic environment. It will be used to study the faint solar coronal magnetic field across a large field-of-view. Such a complex and precise instrument demands equal requirements from the control system. The control system must handle the many sub-components (e.g. cameras, polarimeter, mirrors) and bring them all together to manage the setup, timings, synchronization, real time motion and overall monitoring. It is built within the pre-defined DKIST software framework, which provides consistency across all instruments. This paper will discuss how such a control system has been achieved for the Cryo-NIRSP instrument detailing some of the challenges that were overcome relating to the synchronization of specific components and the complex inter-dependencies between configurables. It will also touch on the data processing and visualization software development for the end-to-end functioning of the instrument.

At the center for Proton Therapy of the Paul Scherrer Institute about 450 cancer patients are treated yearly using accelerated protons in three treatment areas. The facility is active since 1984 and for each patient we keep detailed log files containing machine measurements during each fraction of the treatment, which we analyze daily to guarantee dose and position values within the prescribed tolerances. Furthermore, each control and safety system generates textual log files as well as periodic measurements such as pressure, temperature, beam intensity, magnetic fields or reaction time of components. This adds up currently to approximately 5 GB per day. Downtime of the facility is both inconvenient for patients and staff, as well as financially relevant. This article describes how we have extended our data analysis strategies using machine archived parameters and online measurements to understand interdependencies, to perform preventive maintenance of ageing components and to optimize processes. We have chosen Python to interface, structure and analyze the different data sources in an standardized manner. The online channels have been accessed via an EPICS archiver.
