MO3AO04	Modelling and Control of a MeerKAT Antenna	controls, target, experiment, factory	131
	I.A. Dodia SARAO, Cape Town, South Africa
	This paper presents a comprehensive approach to modeling for control system design for a MeerKAT antenna. It focuses on dynamic modeling using time and frequency domain techniques, and lays the foundation for the design of a control system to meet the telescope’s stringent pointing and tracking requirements. The paper scope includes rigid body modelling of the antenna, system identification to obtain model parameters, and building a system model in Simulink. The Simulink model allows us to compare model performance with the measured antenna pointing, under various environmental conditions. The paper also integrates models for pointing disturbances, such as wind and friction. The integrated model is compared to the existing control setup. Wind disturbance plays a significant role in the pointing performance of the antenna, therefore the focus is placed on developing an appropriate wind model. This research will conclude by providing a well-documented, systematic control system design that is owned by SARAO and can be implemented to improve the pointing performance of the telescope.

MO4BCO05	Apples to Oranges: A Comparison of EPICS Build and Deployment Systems	EPICS, LLRF, controls, MMI	205
	S.C.F. Rose, D.H.C. Araujo, L.A. Mello Magalhães, A.L. Olsson ESS, Lund, Sweden
	ESS currently uses two different systems for managing the build and deployment of EPICS modules. Both of these use modules that are packaged and prepared to be dynamically loaded into soft IOCs, based on the require module developed at PSI. The difference is the deployment: For the accelerator, we use a custom utility to define and build an EPICS environment which is then distributed on a global shared filesystem to the production and lab networks. For the neutron instrumentation side, in contrast, we use conda to build individual EPICS environments for each IOC, where the underlying packages are stored on a shared artifactory server. In each case, the goal is to provide a repeatable and controllable mechanism to produce a consistent EPICS environment for IOCs in use at ESS. The difference (other than the tools and storage) is in some sense philosophical: should a software environment be defined at build-time or at run-time? In this presentation we will provide an overview of some of the challenges, contrasts, and lessons learned from these two different but related approaches to EPICS module deployment.

MO4AO05	Development of a Timing and Data Link for EIC Common Hardware Platform	network, timing, FPGA, alignment	228
	P. Bachek, T. Hayes, J. Mead, K. Mernick, G. Narayan, F. Severino BNL, Upton, New York, USA
	Funding: Contract Number DE-AC02-98CH10886 with the auspices of the US Department of Energy Modern timing distribution systems benefit from high configurability and the bidirectional transfer of timing data. The Electron Ion Collider (EIC) Common Hardware Platform (CHP) will integrate the functions of the existing RHIC Real Time Data Link (RTDL), Event Link, and Beam Sync Link, along with the Low-Level RF (LLRF) system Update Link (UL), into a common high speed serial link. One EIC CHP carrier board sup-ports up to eight external 8 Gbps high speed links via SFP+ modules, as well as up to six 8 Gbps high speed links to each of two daughterboards. A daughterboard will be designed for the purpose of timing data link distribution for use with the CHP. This daughterboard will have two high speed digital crosspoint switches and a Xilinx Artix Ultrascale⁺ FPGA onboard with GTY transceivers. One of these will be dedicated for a high-speed control and data link directly between the onboard FPGA and the carrier FPGA. The remaining GTY transceivers will be routed through the crosspoint switches. The daughterboard will support sixteen external SFP+ ports for timing distribution infrastructure with some ports dedicated for transmit only link fanout. The timing data link will support bidirectional data transfer including sending data or events from a downstream device back upstream. This flexibility will be achieved by routing the SFP+ ports through the crosspoint switches which allows the timing link datapaths to be forwarded directly through the daughterboard to the carrier and into the FPGA on the daughterboard in many different configurations.

TUPDP082	Target Safety System Maintenance	target, operation, proton, PLC	709
	A. Sadeghzadeh, L. Coney, O. Ingemansson, O.J. Janson, M. Olsson ESS, Lund, Sweden
	The Target Safety System (TSS) is part of the overall radiation safety plan for the Target Station in the European Spallation Source (ESS). ESS, Target Division, Target Controls and Safety group is responsible for the design and construction of the TSS. TSS stops Proton production if vital process conditions measured at the Target Station, are outside the set boundaries with the potential of causing (radiation) injury to third parties (public outside ESS fences). The TSS is a 3-channel fail-safe safety system consisting of independent sensors, a two redundant train system based on relay and safety PLC technique and independent ways of stopping the proton beam accelerator. TSS will continuously monitor safety parameters in the target He cooling, wheel, and monolith atmosphere systems, evaluate their conditions, and turn off the proton beam if necessary. After passing several stages of off-site test, the TSS cabinets are now installed on site and successfully passed internal integration. In this paper we will explain features we fit into the system to ease emergency repairs, system modification and system safety verification and in general maintainability of the system.

	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.

WE3BCO03	Data Management for Tracking Optic Lifetimes at the National Ignition Facility	optics, database, laser, status	1012
	R.D. Clark, L.M. Kegelmeyer LLNL, Livermore, California, USA
	Funding: This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. The National Ignition Facility (NIF), the most energetic laser in the world, employs over 9000 optics to reshape, amplify, redirect, smooth, focus, and convert the wavelength of laser light as it travels along 192 beamlines. Underlying the management of these optics is an extensive Oracle database storing details of the entire life of each optic from the time it leaves the vendor to the time it is retired. This journey includes testing and verification, preparing, installing, monitoring, removing, and in some cases repairing and re-using the optics. This talk will address data structures and processes that enable storing information about each step like identifying where an optic is in its lifecycle and tracking damage through time. We will describe tools for reporting status and enabling key decisions like which damage sites should be blocked or repaired and which optics exchanged. Managing relational information and ensuring its integrity is key to managing the status and inventory of optics for NIF. LLNL Release Number: LLNL-ABS-847598

Syder DLS, Oxfordshire, United Kingdom
	The ICAT metadata catalogue is a flexible solution for managing scientific metadata and data from a wide variety of domains following the FAIR data principles. This paper will present an update of recent developments of the ICAT metadata catalogue and the latest status of the ICAT collaboration. ICAT was originally developed by UK Science and Technology Facilities Council (STFC) to manage the scientific data of ISIS Neutron and Muon Source and Diamond Light Source. They have since been joined by a number of other institutes including ESRF, HZB, SESAME, and ALBA who together now form the ICAT Collaboration [1]. ICAT has been used to manage petabytes of scientific data for ISIS, DLS, ESRF, HZB, and in the future SESAME and ALBA and make these data FAIR. The latest version of the ICAT core as well as the new user interfaces, DataGateway and DataHub, and extensions to ICAT for implementing free text searching, a common search interface across Photon and Neutron catalogues, a protocol-based interface that allows making the metadata available for findability, electronic logbooks, sample tracking, and web-based data and domain specific viewers developed by the community will be presented. Finally recent developments to use ICAT to develop applications for processed data with rich metadata in the fields of small angle scattering, macromolecular crystallography and cryo-electron microscopy will be described.

TH2AO02	High Availability Alarm System Deployed with Kubernetes	monitoring, status, interface, feedback	1134
	J.J. Bellister, T. Schwander, T. Summers SLAC, Menlo Park, California, USA
	To support multiple scientific facilities at SLAC, a modern alarm system designed for availability, integrability, and extensibility is required. The new alarm system deployed at SLAC fulfills these requirements by blending the Phoebus alarm server with existing open-source technologies for deployment, management, and visualization. To deliver a high-availability deployment, Kubernetes was chosen for orchestration of the system. By deploying all parts of the system as containers with Kubernetes, each component becomes robust to failures, self-healing, and readily recoverable. Well-supported Kubernetes Operators were selected to manage Kafka and Elasticsearch in accordance with current best practices, using high-level declarative deployment files to shift deployment details into the software itself and facilitate nearly seamless future upgrades. An automated process based on git-sync allows for automated restarts of the alarm server when configuration files change eliminating the need for sysadmin intervention. To encourage increased accelerator operator engagement, multiple interfaces are provided for interacting with alarms. Grafana dashboards offer a user-friendly way to build displays with minimal code, while a custom Python client allows for direct consumption from the Kafka message queue and access to any information logged by the system.

THPDP030	ESS Drift Tube Linac Control System Commissioning: Results and Lessons Learned	controls, DTL, EPICS, hardware	1377
	M. Montis, L. Antoniazzi, A. Baldo, M.G. Giacchini INFN/LNL, Legnaro (PD), Italy A. Rizzo ESS, Lund, Sweden
	European Spallation Source (ESS) will be a neutron source using proton beam Linac of expected 5MW beam power. Designed and implemented by INFN-LNL, the Drift Tube Linac (DTL) control system is based on EPICS framework as indicated by the Project Requirements. This document aims to describe the results of the first part of the control system commissioning stage in 2022, where INFN and ESS teams were involved in the final tests on site. This phase was the first step toward a complete de-ployment of the control system, where the installation was composed by three sequential stages, according to the apparatus commissioning schedule. In this scenario, the firsts Site Acceptance Test (SAT) and Site Integrated Test (SIT) were crucial, and their results were the mile-stones for the other stages: the lessons learned can be important to speed up the future integration, calibration, and tuning of such a complex control system.

FR1BCO03	SKA Project Status Update	software, MMI, status, controls	1610
	N.P. Rees SKAO, Macclesfield, United Kingdom
	The SKA Project is a science mega-project whose mission is to build the world’s two largest radio telescopes with sensitivity, angular resolution, and survey speed far surpassing current state-of-the-art instruments at relevant radio frequencies. The Low Frequency telescope, SKA-Low, is designed to observe between 50 and 350 MHz and will be built at Inyarrimanha Ilgari Bundara, the CSIRO Murchison Radio-astronomy Observatory in Western Australia. The Mid Frequency telescope, SKA-Mid, is designed to observe between 350 MHz and 15 GHz and will be built in the Meerkat National Park, in the Northern Cape of South Africa. Each telescope will be delivered in a number of stages, called Array Assemblies. Each Array Assembly will be a fully working telescope which will allow us to understand the design and potentially improve the system to deliver a better scientific instrument for the users. The final control system will consist of around 2 million control points per telescope, and the first Array Assembly, known as AA0.5, is being delivered at the time of ICALEPCS 2023.

Funding: This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.
The National Ignition Facility (NIF), the most energetic laser in the world, employs over 9000 optics to reshape, amplify, redirect, smooth, focus, and convert the wavelength of laser light as it travels along 192 beamlines. Underlying the management of these optics is an extensive Oracle database storing details of the entire life of each optic from the time it leaves the vendor to the time it is retired. This journey includes testing and verification, preparing, installing, monitoring, removing, and in some cases repairing and re-using the optics. This talk will address data structures and processes that enable storing information about each step like identifying where an optic is in its lifecycle and tracking damage through time. We will describe tools for reporting status and enabling key decisions like which damage sites should be blocked or repaired and which optics exchanged. Managing relational information and ensuring its integrity is key to managing the status and inventory of optics for NIF.

The ICAT metadata catalogue is a flexible solution for managing scientific metadata and data from a wide variety of domains following the FAIR data principles. This paper will present an update of recent developments of the ICAT metadata catalogue and the latest status of the ICAT collaboration. ICAT was originally developed by UK Science and Technology Facilities Council (STFC) to manage the scientific data of ISIS Neutron and Muon Source and Diamond Light Source. They have since been joined by a number of other institutes including ESRF, HZB, SESAME, and ALBA who together now form the ICAT Collaboration [1]. ICAT has been used to manage petabytes of scientific data for ISIS, DLS, ESRF, HZB, and in the future SESAME and ALBA and make these data FAIR. The latest version of the ICAT core as well as the new user interfaces, DataGateway and DataHub, and extensions to ICAT for implementing free text searching, a common search interface across Photon and Neutron catalogues, a protocol-based interface that allows making the metadata available for findability, electronic logbooks, sample tracking, and web-based data and domain specific viewers developed by the community will be presented. Finally recent developments to use ICAT to develop applications for processed data with rich metadata in the fields of small angle scattering, macromolecular crystallography and cryo-electron microscopy will be described.

After its first release in 2017, EPICS version 7 has been introduced into production at several sites. The central feature of EPICS 7, the support of structured data through the new pvAccess network protocol, has been proven to work in large production systems. EPICS 7 facilitates the implementation of new functionality, including developing AI/ML applications in controls, managing large data volumes, interfacing to middle-layer services, and more. Other features like support for the IPv6 protocol and enhancements to access control have been implemented. Future work includes integrating a refactored API into the core distribution, adding modern network security features, as well as developing new and enhancing existing services that take advantage of these new capabilities. The talk will give an overview of the status of deployments, new additions to the EPICS Core, and an overview of its planned future development.

To support multiple scientific facilities at SLAC, a modern alarm system designed for availability, integrability, and extensibility is required. The new alarm system deployed at SLAC fulfills these requirements by blending the Phoebus alarm server with existing open-source technologies for deployment, management, and visualization. To deliver a high-availability deployment, Kubernetes was chosen for orchestration of the system. By deploying all parts of the system as containers with Kubernetes, each component becomes robust to failures, self-healing, and readily recoverable. Well-supported Kubernetes Operators were selected to manage Kafka and Elasticsearch in accordance with current best practices, using high-level declarative deployment files to shift deployment details into the software itself and facilitate nearly seamless future upgrades. An automated process based on git-sync allows for automated restarts of the alarm server when configuration files change eliminating the need for sysadmin intervention. To encourage increased accelerator operator engagement, multiple interfaces are provided for interacting with alarms. Grafana dashboards offer a user-friendly way to build displays with minimal code, while a custom Python client allows for direct consumption from the Kafka message queue and access to any information logged by the system.

European Spallation Source (ESS) will be a neutron source using proton beam Linac of expected 5MW beam power. Designed and implemented by INFN-LNL, the Drift Tube Linac (DTL) control system is based on EPICS framework as indicated by the Project Requirements. This document aims to describe the results of the first part of the control system commissioning stage in 2022, where INFN and ESS teams were involved in the final tests on site. This phase was the first step toward a complete de-ployment of the control system, where the installation was composed by three sequential stages, according to the apparatus commissioning schedule. In this scenario, the firsts Site Acceptance Test (SAT) and Site Integrated Test (SIT) were crucial, and their results were the mile-stones for the other stages: the lessons learned can be important to speed up the future integration, calibration, and tuning of such a complex control system.

SKAO, Macclesfield, United Kingdom

The SKA Project is a science mega-project whose mission is to build the world’s two largest radio telescopes with sensitivity, angular resolution, and survey speed far surpassing current state-of-the-art instruments at relevant radio frequencies. The Low Frequency telescope, SKA-Low, is designed to observe between 50 and 350 MHz and will be built at Inyarrimanha Ilgari Bundara, the CSIRO Murchison Radio-astronomy Observatory in Western Australia. The Mid Frequency telescope, SKA-Mid, is designed to observe between 350 MHz and 15 GHz and will be built in the Meerkat National Park, in the Northern Cape of South Africa. Each telescope will be delivered in a number of stages, called Array Assemblies. Each Array Assembly will be a fully working telescope which will allow us to understand the design and potentially improve the system to deliver a better scientific instrument for the users. The final control system will consist of around 2 million control points per telescope, and the first Array Assembly, known as AA0.5, is being delivered at the time of ICALEPCS 2023.
