TUMBCMO05	PyDM Development Update	349
	J.J. Bellister, Y.G. Yazar SLAC, Menlo Park, California, USA
	PyDM is a PyQt-based framework for building user interfaces for control systems. It provides a no-code, drag-and-drop system to make simple screens, as well as a straightforward Python framework to build complex applications. Recent updates include expanded EPICS PVAccess support using the P4P module. A new widget has been added for displaying data received from NTTables. Performance improvements have been implemented to enhance the loading time of displays, particularly those that heavily utilize template repeaters. Additionally, improved documentation and tutorial materials, accompanied by a sample template application, make it easier for users to get started.

TUMBCMO07	Dynamic Control Room Interfaces for Complex Particle Accelerator Systems	351
	B.E. Bolling, G. Fedel, M. Muñoz, D.N. Nordt ESS, Lund, Sweden
	The European Spallation Source (ESS) is a research facility under construction aiming to be the world’s most powerful pulsed neutron source. It is powered by a complex particle accelerator designed to provide a 2.86 ms long proton pulse at 2 GeV with a repetition rate of 14 Hz. Commissioning of the first part of the accelerator has begun and the requirements on the control system interfaces varies greatly as progress is made and new systems are added. In this paper, three such applications are discussed in separate sections. A Navigator interface was developed for the control room interfaces aimed towards giving operators and users a clear and structured way towards quickly finding the needed interface(s) they need. The construction of this interface is made automatically via a Python-based application and is built on applications in any directory structure both with and without developer interference (fully and semi-automatic methods). The second interface discussed in this paper is the Operations Accelerator Synoptic interface, which uses a set of input lattices and system interface templates to construct configurable synoptic view of the systems in various sections and a controller panel for any selected system. Lastly for this paper there is a configurable Radio Frequency Orchestration interface for Operations, which allows in-situ modification of the interface depending on which systems and components are selected.

TUMBCMO08	Extending Phoebus Data Browser to Alternative Data Sources	355
	M. Romanovschi, I.D. Finch, G.D. Howells STFC/RAL/ISIS, Chilton, Didcot, Oxon, United Kingdom
	The Phoebus user interface to EPICS is an integral part of the new control system for the ISIS Neutron and Muon Source accelerators and targets. Phoebus can use the EPICS Archiver Appliance, which has been deployed as part of the transition to EPICS, to display the history of PVs. However, ISIS data has and continues to be stored in the InfluxDB time series database. To enable access to this data, a Python application to interface between Phoebus and other databases has been developed. Our implementation utilises Quart, an asynchronous web framework, to allow multiple simultaneous data requests. Google Protocol Buffer, natively supported by Phoebus, is used for communication between Phoebus and the database. By employing subclassing, our system can in principle adapt to different databases, allowing flexibility and extensibility. Our open-source approach enhances Phoebus’s capabilities, enabling the community to integrate it within a wider range of applications.

TUMBCMO09	Front-End Monitor and Control Web Application for Large Telescope Infrastructures: A Comparative Analysis	359
	S. Di Frischia, M. Canzari INAF - OAAB, Teramo, Italy V. Alberti INAF-OAT, Trieste, Italy A. Georgiou CGI, Edinburgh, United Kingdom H.R. Ribeiro Universidade do Porto, Faculdade de Ciências, Porto, Portugal
	A robust monitor and control front-end application is a crucial feature for large and scalable radio telescope infrastructures such LOFAR and SKA, whereas the control system is required to manage numerous attribute values at a high update rate, and thus the operators must rely on an affordable user-interface platform which covers the whole range of operations. In this paper two state-of-the-art web applications such Grafana and Taranta are taken into account, developing a comparative analysis between the two software suites. Such a choice is motivated mostly because of their widespread use together with the TANGO Controls Framework, and the necessity to offer a ground of comparison for large projects dealing with the development of a monitor and control GUI which interfaces to TANGO. We explain at first the general architecture of both systems, and then we create a typical use-case where an interactive dashboard is built to monitor and control a hardware device. Then, we set up some comparable metrics to evaluate the pros and cons of both platforms, regarding the technical and operational requirements, fault tolerances, developers and operators efforts, and so on. In conclusion, the comparative analysis and its results are summarized with the aim to offer the stakeholders a basis for future choices.

TUMBCMO11	Upgrading and Adapting to CS-Studio Phoebus at Facility for Rare Isotope Beams	364
	T. Ashwarya, M. Ikegami, J. LeTourneau, A.C. Morton FRIB, East Lansing, Michigan, USA
	Funding: Work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DE-SC0000661 For more than a decade, the Eclipse-based Control System Studio has provided FRIB with a rich user interface to its EPICS-based control system. At FRIB, we use the Alarm Handler, BOY Display Manager, Scan Monitor/Editor, Channel Client, Save-and-Restore, and Data Browser to monitor and control various parts of the beamline. Our engineers have developed over 3000 displays using the BOY display manager mapping various segments and areas of the FRIB beamline. CS-Studio Phoebus is the latest next-generation upgrade to the Eclipse-based CS-Studio, which is based on the modern JavaFX-based graphics and aims toward providing existing functionalities and more. FRIB has already transitioned away from the old BEAST alarm servers to the new Kafka-based Phoebus alarm servers which have been monitoring thousands of our EPICS PVs with its robust monitoring and notifying capabilities. We faced certain challenges with conversion of FRIB’s thousands of displays and to address those we deployed scripts to help the bulk conversion of screens with automated mapping between BOY and Display Builder and also continually improved the Phoebus auto-conversion tool. This paper details the ongoing transition of FRIB from Eclipse-based CS-Studio to Phoebus and various adaptations and solutions that we used to ease this transition for our users. Moving to the new Phoebus-based services and client have provided us with an opportunity to rectify and improve on certain issues known to have existed with Eclipse-based CS-Studio and its services.

TUMBCMO12	Multi-Dimensional Spectrogram Application for Live Visualization and Manipulation of Large Waveforms	368
	B.E. Bolling, A.A. Gorzawski, J. Peterson ESS, Lund, Sweden
	The European Spallation Source (ESS) is a research facility under construction aiming to be the world’s most powerful pulsed neutron source. It is powered by a complex particle accelerator designed to provide a 2.86 ms long proton pulse at 2 GeV with a repetition rate of 14 Hz. Protons are accelerated via cavity fields through various accelerating structures that are powered by Radio-Frequency (RF) power. As the cavity fields may break down due to various reasons, usually post-mortem data of such events contain the information needed regarding the cause. In other events, the underlying cause may have been visible on previous beam pulses before the interlock triggering event. The Multi-Dimensional Spectrogram Application is designed to be able to collect, manipulate and visualize large waveforms at high repetition rates, with the ESS goal being 14 Hz, for example cavity fields, showing otherwise unnoticed temporary breakdowns that may explain the sometimes-unknown reason for increased power (compensating for those invisible temporary breakdowns). The first physical event that was recorded with the tool was quenching of a superconducting RF cavity in real time in 3D. This paper describes the application developed using Python and the pure-python graphics and GUI library PyQtGraph and PyQt5 with Python-OpenGL bindings.

TUPDP039	Integrating EPICS Control System in VR Environment: Proof of Concept	599
	L. Pranovi, M. Montis INFN/LNL, Legnaro (PD), Italy
	Preliminary activities were performed to verify the feasibility of Virtual Reality (VR) and Augmented Reality (AR) technologies applied to nuclear physics laboratories, using them for different purposes: scientific dissemination events, data collection, training, and machine maintenance. In particular, this last field has been fascinating since it lets developers discover the possibility of redesigning the concept of the Human-Machine Interface. Based on the experience, it has been natural to try to provide to the final user (such as system operators and maintainers) with all the set of information describing the machine and control system parameters. For this reason, we tried to integrate the accelerator’s control system environment and VR/AR application. In this contribution, the integration of an EPICS-based control system and VR environment will be described.

TUPDP044	Improving Performance of Taranta: Analysis of Memory Requests and Implementation of the Solution	617
	M. Canzari INAF - OAAB, Teramo, Italy V. Alberti INAF-OAT, Trieste, Italy A. Dubey PSL, Pune, India M. Eguiraun, J. Forsberg, V. Hardion MAX IV Laboratory, Lund University, Lund, Sweden A. Georgiou CGI, Edinburgh, United Kingdom H.R. Ribeiro Universidade do Porto, Faculdade de Ciências, Porto, Portugal
	Taranta is a software suite for generating graphical interfaces for Tango Controls software, currently adopted by MaxIV for scientific experiment usage, SKA during the current construction phase for the development of engineering interfaces for device debugging, and other institutions. A key feature of Taranta is the ability to create customizable dashboards without writing code, making it easy to create and share views among users by linking the dashboards to their own tango devices. However, due to the simplicity and capabilities of Taranta’s widgets, more and more users are creating complex dashboards, which can cause client-side resource problems. Through an analysis of dashboards, we have found that excessive memory requests are generated by a large amount of data. In this article, we report on the process we believe will help us solve this performance issue. Starting with an analysis of the existing architecture, the issues encountered, and performance tests, we identify the causes of these problems. We then study a new architecture exploiting all the potential of the Javascript framework React on which Taranta is built, before moving on to implementation of the solution.

TUPDP059	Integrated Controls Alarms Managemet Solution
	P.P. Goryl, M. Gandor, J.T. Kowalczyk, Ł. Żytniak S2Innovation, Kraków, Poland
	Whereas both EPICS and Tango Controls and commercial SCADA solutions provide alarming solutions, there is a lack of a tool that supports multiple systems simultaneously. At the same time, some facilities use different control software frameworks for accelerators and beamlines. Then, during and after covid pandemic, institutes got used to working remotely. Having a tool, which unifies alarms notifications and handling will simplify facilities’ operation. The S2Innovation’s web-based solution, which at first supports only Tango Control’s system has been adopted to support other frameworks, too. Now, it can integrate EPICS record-based alarms, PyAlarm, AlarmHandler (Elettra) and Achtung (MAX-IV). Integration with other systems is also planned. The features, integration models, as well as potential benefits of using such a tool, will be presented.

TUPDP089	Improving CERN’s Web-based Rapid Application Platform	740
	E. Galatas, S. Deghaye, J. Raban, C. Roderick, D. Saxena, A. Solomou CERN, Meyrin, Switzerland
	The Web-based Rapid Application Platform (WRAP) aims to provide a centralized, zero-code, drag-n-drop means of GUI creation. It was developed at CERN to address the high maintenance cost of supporting multiple evolving GUI-technologies and minimising duplication of effort by those developing different GUI applications. WRAP leverages web technologies and existing controls infrastructure to provide a drop-in solution for a range of use cases. However, providing a centralized platform to cater for diverse needs and to interact with a multitude of data sources presented performance, design, and deployment challenges. This paper describes how the WRAP architecture has evolved to address these challenges, overcoming technological limitations, increasing usability and the resulting end-user adoption.

TUPDP090	Web Application Packaging - Deploying Web Applications as Traditional Desktop Applications in CERN’s Control Centre	746
	M.H. von Hohenbühel, S. Deghaye, E. Galatas, E. Matli, E. Roux CERN, Meyrin, Switzerland
	Web applications are becoming increasingly performant and are now capable, in many cases, of replacing traditional desktop applications. There is also a user demand for web-based applications, surely linked to their modern look & feel, their ease of access, and the overall familiarity of the users with web applications due to their pervasive nature. However, when it comes to a Controls environment, the limitations caused by the fact that web applications run inside a web browser are often seen as a major disadvantage when compared to native desktop applications. In addition, applications deployed in CERN’s Control Centre are tightly integrated with the control system and use a CERN-specific launcher and manager that does not easily integrate with web browsers. This paper presents an analysis of the approaches that have been considered for deploying web applications and integrating them with CERN’s control system. The implications on the development process, the IT infrastructure, the deployment methods as well as the performance impact on the resources of the target computers are also discussed.

TUPDP113	A Flexible EPICS Framework for Sample Alignment at Neutron Beamlines	836
	J.P. Edelen, M.J. Henderson, M.C. Kilpatrick RadiaSoft LLC, Boulder, Colorado, USA S. Calder, B. Vacaliuc ORNL RAD, Oak Ridge, Tennessee, USA R.D. Gregory, G.S. Guyotte, C.M. Hoffmann, B.K. Krishna 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 Science under Award Number DE-SC0021555. RadiaSoft has been developing a flexible front-end framework, written in Python, for rapidly developing and testing automated sample alignment IOCs at Oak Ridge National Laboratory. We utilize YAML-formatted configuration files to construct a thin abstraction layer of custom classes which provide an internal representation of the external hardware within a controls system. The abstraction layer takes advantage of the PCASPy and PyEpics libraries in order to serve EPICS process variables & respond to read/write requests. Our framework allows users to build a new IOC that has access to information about the sample environment in addition to user-defined machine learning models. The IOC then monitors for user inputs, performs user-defined operations on the beamline, and reports on its status back to the control system. Our IOCs can be booted from the command line, and we have developed command line tools for rapidly running and testing alignment processes. These tools can also be accessed through an EPICS GUI or in separate Python scripts. This presentation provides an overview of our software structure and showcases its use at two beamlines at ORNL.

TUPDP127	SLAC LINAC Mode Manager Interface	882
	T. Summers, C. Bianchini Mattison, M. Gibbs, T.J. Kabana, P. Krejcik, J.A. Mock SLAC, Menlo Park, California, USA
	With the successful commissioning of the new superconducting (SC) LINAC, the LINAC Coherent Light Source (LCLS) now has the capability of interleaving beams from either the normal conducting (NC) LINAC or the SC LINAC to two different destinations, the soft (SXR) and hard (HXR) x-ray undulator beamlines. A mode manager user interface has been created to manage the beamline configuration to transport beam pulses to multiple destinations, which include the numerous intermediate tune-up dumps and safety dumps between the injectors and the final beam dumps. The mode manager interfaces with the timing system which controls the bunch patterns to the various locations, and the machine protection system which prevents excess beam power from being sent to the wrong destination. This paper describes the implementation method for handling the mode switching, as well as the operator user interface which allows users to graphically select the desired beam paths.

	Y.G. Yazar, J.J. Bellister, Z.A. Domke, T. Summers SLAC, Menlo Park, California, USA F.M. Osman Santa Clara University, Santa Clara, California, USA
	A new open-source PyQT-based archive viewer application has been developed at SLAC National Accelerator Laboratory. The viewer’s main purpose is to visualize both live values and historical Process Variable (PV) data retrieved from the EPICS Archive Appliances. It is designed as both a stand-alone application and to be easily launched from widgets on PyDM operator interfaces. In addition to providing standard configurability for things like traces, formulas, style and data exporting, it provides post-processing capabilities for filtering and curve fitting. The current release supports standard enumerated and analog data types as well as waveforms. Extension of this to support EPICS7 normative data types such as NTTable and NTNDArray is under development.

TUSDSC07	Web Dashboards for CERN Radiation and Environmental Protection Monitoring	938
	A. Ledeul, A. Savulescu, G. Segura CERN, Meyrin, Switzerland
	CERN has developed and operates a SCADA system for radiation and environmental monitoring, which is used by many users with different needs and profiles. To provide tailored access to this control system¿s data, the CERN’s Occupational Health & Safety and Environmental Protection (HSE) Unit has developed a web-based dashboard editor that allows users to create custom dashboards for data analysis. In this paper, we present a technology stack comprising Spring Boot, React, Apache Kafka, WebSockets, and WebGL that provides a powerful tool for a web-based presentation layer for the SCADA system. This stack leverages WebSocket for near-real-time communication between the web browser and the server. Additionally, it provides high-performant, reliable, and scalable data delivery using low-latency data streaming with Apache Kafka. Furthermore, it takes advantage of the GPU’s power with WebGL for data visualization. This web-based dashboard editor and the technology stack provide a faster, more integrated, and accessible solution for building custom dashboards and analyzing data.

	The Phoebus toolkit consists of a variety of control system applications providing user interfaces to control systems and middle-layer services. Phoebus is the latest incarnation of Control System Studio (CS-Studio), which has been redesigned replacing the underlying Eclipse RCP framework with standard Java alternatives like SPI, preferences, etc. Additionally the GUI toolkit was switched from SWT to JavaFX. This new architecture has not only simplified the development process while preserving the extensible and pluggable aspects of RCP, but also improved the performance and reliability of the entire toolkit. The Phoebus technology stack includes a set of middle-layer services that provide functionality like archiving, creating and restoring system snapshots, consolidating and organizing alarms, user logging, name lookup, etc. Designed around modern and widely used web and storage technologies like Spring Boot, Elastic, MongoDB, Kafka, the Phoebus middle-layer services are thin, scalable, and can be easily incorporated in CI/CD pipelines. The clients in Phoebus leverage the toolkit’s integration features, including common interfaces and utility services like adapter and selection, to provide users with a seamless experience when interacting with multiple services and control systems. This presentation aims to provide an overview of the Phoebus technology stack, highlighting the benefits of integrated tools in Phoebus and the microservices architecture of Phoebus middle-layer services.

FR2BCO02	A Lean UX Approach for Developing Effective Monitoring and Control User Interfaces: A Case Study for the SKA CSP. LMC Subsystem	1650
	V. Alberti INAF-OAT, Trieste, Italy C. Baffa, E. Giani, G. Marotta INAF - OA Arcetri, Firenze, Italy G. Brajnik IDS, Udine, Italy M. Colciago, I. Novak Cosylab Switzerland, Brugg, Switzerland
	The Central Signal Processor Local Monitor and Control (CSP. LMC) is a software component that allows the flow of information and commands between the Telescope Manager (TM) and the subsystems dedicated to signal processing, namely the correlator and beamformer, the pulsar search and the pulsar timing engines. It acts as an adapter by specialising the commands and associated data from the TM to the subsystems and by exposing the subsystems as a unified entity while monitoring their status. In this paper, we approach the problem of creating a User Interface (UI) for such a component. Through a series of short learning cycles, we want to explore different ways of looking at the system and build an initial set of UIs that can be refined to be used as engineering UIs in the first Array Assembly of the Square Kilometre Array. The process heavily involves some of the developers of the CSP. LMC in creating the dashboards, and other ones as participants in informal evaluations. In fact, the opportunities offered by Taranta, a tool to develop web UIs without needing web-development skills, make it possible to quickly realise a working dashboard that can be promptly tested. This also supports the short feedback cycle advocated by a Lean UX approach and maps well in a bi-weekly sprint cadence. In this paper, we will describe the method and present the results highlighting strengths and pain points where faced.

	Taranta, developed jointly by MAX IV Laboratory and SKA Observatory, is a web based no-code interface for remote control of instruments at accelerators and other scientific facilities. It has seen a great success in system development and scientific experiment usage. In the past two years, the panel of users has greatly expanded. The first generation of Taranta was not able to handle the challenges introduced by the user cases, notably the decreased performance when a high number of data points are requested, as well as new functionality requests. Therefore, a series of refactoring and performance improvements of Taranta are ongoing, to prepare it for handling large data transmission between Taranta and multiple sources of information, and to provide more possibilities for users to develop their own dashboards. This article presents the status of the Taranta project from the aspects of widgets updates, packages management, optimization of the communication with the backend TangoGQL, as well as the investigation on a new python library compatible with the newest python version for TangoGQL. In addition to the technical improvements, more facilities other than MAX IV and SKAO are considering to join Taranta project. One workshop has been successfully held and there will be more in the future. This article also presents the lesson learned from this project, the road map, and the GUI strategy for the near future.

FR2BCO04	Micro Frontends - a New Migration Process for Monolithic Web Applications	1663
	A. Asko, S. Deghaye, E. Galatas, A.E. Kustra, C. Roderick, B. Urbaniec CERN, Meyrin, Switzerland
	Numerous standalone web applications have been developed over the last 10 years to support the configuration and operation of the CERN accelerator complex. These applications have different levels of complexity, but they all support hundreds of users for essential activities. A monolithic architecture has been utilised so far, tailoring the standalone applications to specific accelerator needs. The global GUI technology landscape continues to evolve quickly, with most GUI technologies typically reaching end-of-life within 1-to-5 years. Keeping up-to-date with technologies presents a major challenge for the GUI application maintainers, with larger monolithic applications requiring long migration cycles which impede the introduction of new functionalities during the migration phase. To tackle the above issues within the CERN Controls domain, a new Micro Frontend architecture has been introduced and is being used to gradually migrate a large and complex AngularJS-based web application to Angular. This paper introduces the new generic architecture, which is not tied to any specific web framework. The development workflow, challenges, and lessons learned so far will be covered. The differences of this approach, particularly when compared to monolithic application technology migrations, will also be discussed.

FR2BCO05	Magnet Information Management System Based on Web Application for the KEK e⁻/e⁺ Injector Linac	1669
	M. Satoh, Y. Enomoto KEK, Ibaraki, Japan T. Kudou Mitsubishi Electric System & Service Co., Ltd, Tsukuba, Japan
	The KEK injector linac provides e⁻/e⁺ beam to four independent storage rings and a positron damping ring. An accurate information management system of the accelerator components is very important since it is utilized for the beam tuning model. Especially, the incorrect magnet database may cause large deterioration in the quality of beam emittance. In KEK linac, a text-based database system has been used for the information management of magnet system in the long time. It comprises several independent text files which are master information to generate the EPICS database files and the other configuration files required for many linac control software. In this management scheme, it is not easy to access and update any information for the common user except control software expert. For this reason, a new web application-based magnet information management system was developed with the Angular and PHP framework. In the new system, the magnet information can be easily extracted and modified through any web browser for any user. In this paper, we report the new magnet information management system in detail.

SLAC, Menlo Park, California, USA

PyDM is a PyQt-based framework for building user interfaces for control systems. It provides a no-code, drag-and-drop system to make simple screens, as well as a straightforward Python framework to build complex applications. Recent updates include expanded EPICS PVAccess support using the P4P module. A new widget has been added for displaying data received from NTTables. Performance improvements have been implemented to enhance the loading time of displays, particularly those that heavily utilize template repeaters. Additionally, improved documentation and tutorial materials, accompanied by a sample template application, make it easier for users to get started.

Dynamic Control Room Interfaces for Complex Particle Accelerator Systems

351

B.E. Bolling, G. Fedel, M. Muñoz, D.N. Nordt
ESS, Lund, Sweden

The European Spallation Source (ESS) is a research facility under construction aiming to be the world’s most powerful pulsed neutron source. It is powered by a complex particle accelerator designed to provide a 2.86 ms long proton pulse at 2 GeV with a repetition rate of 14 Hz. Commissioning of the first part of the accelerator has begun and the requirements on the control system interfaces varies greatly as progress is made and new systems are added. In this paper, three such applications are discussed in separate sections. A Navigator interface was developed for the control room interfaces aimed towards giving operators and users a clear and structured way towards quickly finding the needed interface(s) they need. The construction of this interface is made automatically via a Python-based application and is built on applications in any directory structure both with and without developer interference (fully and semi-automatic methods). The second interface discussed in this paper is the Operations Accelerator Synoptic interface, which uses a set of input lattices and system interface templates to construct configurable synoptic view of the systems in various sections and a controller panel for any selected system. Lastly for this paper there is a configurable Radio Frequency Orchestration interface for Operations, which allows in-situ modification of the interface depending on which systems and components are selected.

Extending Phoebus Data Browser to Alternative Data Sources

355

The Phoebus user interface to EPICS is an integral part of the new control system for the ISIS Neutron and Muon Source accelerators and targets. Phoebus can use the EPICS Archiver Appliance, which has been deployed as part of the transition to EPICS, to display the history of PVs. However, ISIS data has and continues to be stored in the InfluxDB time series database. To enable access to this data, a Python application to interface between Phoebus and other databases has been developed. Our implementation utilises Quart, an asynchronous web framework, to allow multiple simultaneous data requests. Google Protocol Buffer, natively supported by Phoebus, is used for communication between Phoebus and the database. By employing subclassing, our system can in principle adapt to different databases, allowing flexibility and extensibility. Our open-source approach enhances Phoebus’s capabilities, enabling the community to integrate it within a wider range of applications.

A robust monitor and control front-end application is a crucial feature for large and scalable radio telescope infrastructures such LOFAR and SKA, whereas the control system is required to manage numerous attribute values at a high update rate, and thus the operators must rely on an affordable user-interface platform which covers the whole range of operations. In this paper two state-of-the-art web applications such Grafana and Taranta are taken into account, developing a comparative analysis between the two software suites. Such a choice is motivated mostly because of their widespread use together with the TANGO Controls Framework, and the necessity to offer a ground of comparison for large projects dealing with the development of a monitor and control GUI which interfaces to TANGO. We explain at first the general architecture of both systems, and then we create a typical use-case where an interactive dashboard is built to monitor and control a hardware device. Then, we set up some comparable metrics to evaluate the pros and cons of both platforms, regarding the technical and operational requirements, fault tolerances, developers and operators efforts, and so on. In conclusion, the comparative analysis and its results are summarized with the aim to offer the stakeholders a basis for future choices.

Funding: Work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DE-SC0000661
For more than a decade, the Eclipse-based Control System Studio has provided FRIB with a rich user interface to its EPICS-based control system. At FRIB, we use the Alarm Handler, BOY Display Manager, Scan Monitor/Editor, Channel Client, Save-and-Restore, and Data Browser to monitor and control various parts of the beamline. Our engineers have developed over 3000 displays using the BOY display manager mapping various segments and areas of the FRIB beamline. CS-Studio Phoebus is the latest next-generation upgrade to the Eclipse-based CS-Studio, which is based on the modern JavaFX-based graphics and aims toward providing existing functionalities and more. FRIB has already transitioned away from the old BEAST alarm servers to the new Kafka-based Phoebus alarm servers which have been monitoring thousands of our EPICS PVs with its robust monitoring and notifying capabilities. We faced certain challenges with conversion of FRIB’s thousands of displays and to address those we deployed scripts to help the bulk conversion of screens with automated mapping between BOY and Display Builder and also continually improved the Phoebus auto-conversion tool. This paper details the ongoing transition of FRIB from Eclipse-based CS-Studio to Phoebus and various adaptations and solutions that we used to ease this transition for our users. Moving to the new Phoebus-based services and client have provided us with an opportunity to rectify and improve on certain issues known to have existed with Eclipse-based CS-Studio and its services.

Multi-Dimensional Spectrogram Application for Live Visualization and Manipulation of Large Waveforms

368

B.E. Bolling, A.A. Gorzawski, J. Peterson
ESS, Lund, Sweden

The European Spallation Source (ESS) is a research facility under construction aiming to be the world’s most powerful pulsed neutron source. It is powered by a complex particle accelerator designed to provide a 2.86 ms long proton pulse at 2 GeV with a repetition rate of 14 Hz. Protons are accelerated via cavity fields through various accelerating structures that are powered by Radio-Frequency (RF) power. As the cavity fields may break down due to various reasons, usually post-mortem data of such events contain the information needed regarding the cause. In other events, the underlying cause may have been visible on previous beam pulses before the interlock triggering event. The Multi-Dimensional Spectrogram Application is designed to be able to collect, manipulate and visualize large waveforms at high repetition rates, with the ESS goal being 14 Hz, for example cavity fields, showing otherwise unnoticed temporary breakdowns that may explain the sometimes-unknown reason for increased power (compensating for those invisible temporary breakdowns). The first physical event that was recorded with the tool was quenching of a superconducting RF cavity in real time in 3D. This paper describes the application developed using Python and the pure-python graphics and GUI library PyQtGraph and PyQt5 with Python-OpenGL bindings.

INFN/LNL, Legnaro (PD), Italy

Preliminary activities were performed to verify the feasibility of Virtual Reality (VR) and Augmented Reality (AR) technologies applied to nuclear physics laboratories, using them for different purposes: scientific dissemination events, data collection, training, and machine maintenance*. In particular, this last field has been fascinating since it lets developers discover the possibility of redesigning the concept of the Human-Machine Interface. Based on the experience, it has been natural to try to provide to the final user (such as system operators and maintainers) with all the set of information describing the machine and control system parameters. For this reason, we tried to integrate the accelerator’s control system environment and VR/AR application. In this contribution, the integration of an EPICS-based control system and VR environment will be described.

Taranta is a software suite for generating graphical interfaces for Tango Controls software, currently adopted by MaxIV for scientific experiment usage, SKA during the current construction phase for the development of engineering interfaces for device debugging, and other institutions. A key feature of Taranta is the ability to create customizable dashboards without writing code, making it easy to create and share views among users by linking the dashboards to their own tango devices. However, due to the simplicity and capabilities of Taranta’s widgets, more and more users are creating complex dashboards, which can cause client-side resource problems. Through an analysis of dashboards, we have found that excessive memory requests are generated by a large amount of data. In this article, we report on the process we believe will help us solve this performance issue. Starting with an analysis of the existing architecture, the issues encountered, and performance tests, we identify the causes of these problems. We then study a new architecture exploiting all the potential of the Javascript framework React on which Taranta is built, before moving on to implementation of the solution.

S2Innovation, Kraków, Poland

Whereas both EPICS and Tango Controls and commercial SCADA solutions provide alarming solutions, there is a lack of a tool that supports multiple systems simultaneously. At the same time, some facilities use different control software frameworks for accelerators and beamlines. Then, during and after covid pandemic, institutes got used to working remotely. Having a tool, which unifies alarms notifications and handling will simplify facilities’ operation. The S2Innovation’s web-based solution, which at first supports only Tango Control’s system has been adopted to support other frameworks, too. Now, it can integrate EPICS record-based alarms, PyAlarm, AlarmHandler (Elettra) and Achtung (MAX-IV). Integration with other systems is also planned. The features, integration models, as well as potential benefits of using such a tool, will be presented.

CERN, Meyrin, Switzerland

The Web-based Rapid Application Platform (WRAP) aims to provide a centralized, zero-code, drag-n-drop means of GUI creation*. It was developed at CERN to address the high maintenance cost of supporting multiple evolving GUI-technologies and minimising duplication of effort by those developing different GUI applications. WRAP leverages web technologies and existing controls infrastructure to provide a drop-in solution for a range of use cases. However, providing a centralized platform to cater for diverse needs and to interact with a multitude of data sources presented performance, design, and deployment challenges. This paper describes how the WRAP architecture has evolved to address these challenges, overcoming technological limitations, increasing usability and the resulting end-user adoption.

Web Application Packaging - Deploying Web Applications as Traditional Desktop Applications in CERN’s Control Centre

746

CERN, Meyrin, Switzerland

Web applications are becoming increasingly performant and are now capable, in many cases, of replacing traditional desktop applications. There is also a user demand for web-based applications, surely linked to their modern look & feel, their ease of access, and the overall familiarity of the users with web applications due to their pervasive nature. However, when it comes to a Controls environment, the limitations caused by the fact that web applications run inside a web browser are often seen as a major disadvantage when compared to native desktop applications. In addition, applications deployed in CERN’s Control Centre are tightly integrated with the control system and use a CERN-specific launcher and manager that does not easily integrate with web browsers. This paper presents an analysis of the approaches that have been considered for deploying web applications and integrating them with CERN’s control system. The implications on the development process, the IT infrastructure, the deployment methods as well as the performance impact on the resources of the target computers are also discussed.

RadiaSoft has been developing a flexible front-end framework, written in Python, for rapidly developing and testing automated sample alignment IOCs at Oak Ridge National Laboratory. We utilize YAML-formatted configuration files to construct a thin abstraction layer of custom classes which provide an internal representation of the external hardware within a controls system. The abstraction layer takes advantage of the PCASPy and PyEpics libraries in order to serve EPICS process variables & respond to read/write requests. Our framework allows users to build a new IOC that has access to information about the sample environment in addition to user-defined machine learning models. The IOC then monitors for user inputs, performs user-defined operations on the beamline, and reports on its status back to the control system. Our IOCs can be booted from the command line, and we have developed command line tools for rapidly running and testing alignment processes. These tools can also be accessed through an EPICS GUI or in separate Python scripts. This presentation provides an overview of our software structure and showcases its use at two beamlines at ORNL.

SLAC, Menlo Park, California, USA

With the successful commissioning of the new superconducting (SC) LINAC, the LINAC Coherent Light Source (LCLS) now has the capability of interleaving beams from either the normal conducting (NC) LINAC or the SC LINAC to two different destinations, the soft (SXR) and hard (HXR) x-ray undulator beamlines. A mode manager user interface has been created to manage the beamline configuration to transport beam pulses to multiple destinations, which include the numerous intermediate tune-up dumps and safety dumps between the injectors and the final beam dumps. The mode manager interfaces with the timing system which controls the bunch patterns to the various locations, and the machine protection system which prevents excess beam power from being sent to the wrong destination. This paper describes the implementation method for handling the mode switching, as well as the operator user interface which allows users to graphically select the desired beam paths.

A new open-source PyQT-based archive viewer application has been developed at SLAC National Accelerator Laboratory. The viewer’s main purpose is to visualize both live values and historical Process Variable (PV) data retrieved from the EPICS Archive Appliances. It is designed as both a stand-alone application and to be easily launched from widgets on PyDM operator interfaces. In addition to providing standard configurability for things like traces, formulas, style and data exporting, it provides post-processing capabilities for filtering and curve fitting. The current release supports standard enumerated and analog data types as well as waveforms. Extension of this to support EPICS7 normative data types such as NTTable and NTNDArray is under development.

CERN has developed and operates a SCADA system for radiation and environmental monitoring, which is used by many users with different needs and profiles. To provide tailored access to this control system¿s data, the CERN’s Occupational Health & Safety and Environmental Protection (HSE) Unit has developed a web-based dashboard editor that allows users to create custom dashboards for data analysis. In this paper, we present a technology stack comprising Spring Boot, React, Apache Kafka, WebSockets, and WebGL that provides a powerful tool for a web-based presentation layer for the SCADA system. This stack leverages WebSocket for near-real-time communication between the web browser and the server. Additionally, it provides high-performant, reliable, and scalable data delivery using low-latency data streaming with Apache Kafka. Furthermore, it takes advantage of the GPU’s power with WebGL for data visualization. This web-based dashboard editor and the technology stack provide a faster, more integrated, and accessible solution for building custom dashboards and analyzing data.

The Phoebus toolkit consists of a variety of control system applications providing user interfaces to control systems and middle-layer services. Phoebus is the latest incarnation of Control System Studio (CS-Studio), which has been redesigned replacing the underlying Eclipse RCP framework with standard Java alternatives like SPI, preferences, etc. Additionally the GUI toolkit was switched from SWT to JavaFX. This new architecture has not only simplified the development process while preserving the extensible and pluggable aspects of RCP, but also improved the performance and reliability of the entire toolkit. The Phoebus technology stack includes a set of middle-layer services that provide functionality like archiving, creating and restoring system snapshots, consolidating and organizing alarms, user logging, name lookup, etc. Designed around modern and widely used web and storage technologies like Spring Boot, Elastic, MongoDB, Kafka, the Phoebus middle-layer services are thin, scalable, and can be easily incorporated in CI/CD pipelines. The clients in Phoebus leverage the toolkit’s integration features, including common interfaces and utility services like adapter and selection, to provide users with a seamless experience when interacting with multiple services and control systems. This presentation aims to provide an overview of the Phoebus technology stack, highlighting the benefits of integrated tools in Phoebus and the microservices architecture of Phoebus middle-layer services.

A new generation of Qt graphical components, namely cumbia-qtcontrols-ng is under development at ELETTRA. A common engine allows each component to be rendered on traditional QWidgets and scalable QGraphicsItems alike. The latter technology makes it possible to integrate live controls with static SVG in order to realize any kind of synoptic with touch and scaling capabilities. A pluggable zoomer can be installed on any widget or graphics item. Apply numeric controls, Cartesian and Circular (Radar) plots are the first components realized.

The Central Signal Processor Local Monitor and Control (CSP. LMC) is a software component that allows the flow of information and commands between the Telescope Manager (TM) and the subsystems dedicated to signal processing, namely the correlator and beamformer, the pulsar search and the pulsar timing engines. It acts as an adapter by specialising the commands and associated data from the TM to the subsystems and by exposing the subsystems as a unified entity while monitoring their status. In this paper, we approach the problem of creating a User Interface (UI) for such a component. Through a series of short learning cycles, we want to explore different ways of looking at the system and build an initial set of UIs that can be refined to be used as engineering UIs in the first Array Assembly of the Square Kilometre Array. The process heavily involves some of the developers of the CSP. LMC in creating the dashboards, and other ones as participants in informal evaluations. In fact, the opportunities offered by Taranta, a tool to develop web UIs without needing web-development skills, make it possible to quickly realise a working dashboard that can be promptly tested. This also supports the short feedback cycle advocated by a Lean UX approach and maps well in a bi-weekly sprint cadence. In this paper, we will describe the method and present the results highlighting strengths and pain points where faced.

Taranta, developed jointly by MAX IV Laboratory and SKA Observatory, is a web based no-code interface for remote control of instruments at accelerators and other scientific facilities. It has seen a great success in system development and scientific experiment usage. In the past two years, the panel of users has greatly expanded. The first generation of Taranta was not able to handle the challenges introduced by the user cases, notably the decreased performance when a high number of data points are requested, as well as new functionality requests. Therefore, a series of refactoring and performance improvements of Taranta are ongoing, to prepare it for handling large data transmission between Taranta and multiple sources of information, and to provide more possibilities for users to develop their own dashboards. This article presents the status of the Taranta project from the aspects of widgets updates, packages management, optimization of the communication with the backend TangoGQL, as well as the investigation on a new python library compatible with the newest python version for TangoGQL. In addition to the technical improvements, more facilities other than MAX IV and SKAO are considering to join Taranta project. One workshop has been successfully held and there will be more in the future. This article also presents the lesson learned from this project, the road map, and the GUI strategy for the near future.

Micro Frontends - a New Migration Process for Monolithic Web Applications

1663

CERN, Meyrin, Switzerland

Numerous standalone web applications have been developed over the last 10 years to support the configuration and operation of the CERN accelerator complex. These applications have different levels of complexity, but they all support hundreds of users for essential activities. A monolithic architecture has been utilised so far, tailoring the standalone applications to specific accelerator needs. The global GUI technology landscape continues to evolve quickly, with most GUI technologies typically reaching end-of-life within 1-to-5 years. Keeping up-to-date with technologies presents a major challenge for the GUI application maintainers, with larger monolithic applications requiring long migration cycles which impede the introduction of new functionalities during the migration phase. To tackle the above issues within the CERN Controls domain, a new Micro Frontend architecture has been introduced and is being used to gradually migrate a large and complex AngularJS-based web application to Angular. This paper introduces the new generic architecture, which is not tied to any specific web framework. The development workflow, challenges, and lessons learned so far will be covered. The differences of this approach, particularly when compared to monolithic application technology migrations, will also be discussed.

The KEK injector linac provides e⁻/e⁺ beam to four independent storage rings and a positron damping ring. An accurate information management system of the accelerator components is very important since it is utilized for the beam tuning model. Especially, the incorrect magnet database may cause large deterioration in the quality of beam emittance. In KEK linac, a text-based database system has been used for the information management of magnet system in the long time. It comprises several independent text files which are master information to generate the EPICS database files and the other configuration files required for many linac control software. In this management scheme, it is not easy to access and update any information for the common user except control software expert. For this reason, a new web application-based magnet information management system was developed with the Angular and PHP framework. In the new system, the magnet information can be easily extracted and modified through any web browser for any user. In this paper, we report the new magnet information management system in detail.
