MO3BCO07	Fast Beam Delivery for Flash Irradiations at the HZB Cyclotron	radiation, controls, experiment, cyclotron	178

	In the context of radiotherapy, Flash irradiations mean the delivery of high dose rates of more than 40 Gy/s, in a short time of less than one second. The expectation of the radio-oncologists are lesser side effects while maintaining the tumour control when using Flash. Clinically acceptable deviations of the applied dose to the described dose are less than 3%. Our accelerator control system is well suited for the standard treatment of ocular melanomas with irradiaton times of 30 s to 60 s. However, it is too slow for the short times required in Flash. Thus, a dedicated beam delivery control system has been developed, permitting irradiation times down to 7 ms with a maximal dose variation of less than 3%.

TUMBCMO12	Multi-Dimensional Spectrogram Application for Live Visualization and Manipulation of Large Waveforms	cavity, controls, EPICS, real-time	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.

TUPDP082	Target Safety System Maintenance	target, operation, PLC, site	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.

TUPDP093	CERN Proton Irradiation Facility (IRRAD) Data Management, Control and Monitoring System Infrastructure for post-LS2 Experiments	radiation, experiment, controls, monitoring	762

	Funding: European Union’s Horizon 2020 Research and Innovation programme under GA no 101004761 and Horizon Europe Research and Innovation programme under Grant Agreement No 101057511. Since upgrades of the CERN Large Hadron Collider are planned and design studies for a post-LHC particle accelerator are ongoing, it is key to ensure that the detectors and electronic components used in the CERN experiments and accelerators can withstand the high amount of radiation produced during particle collisions. To comply with this requirement, scientists perform radiation testing experiments, which consist in exposing these components to high levels of particle radiation to simulate the real operational conditions. The CERN Proton Irradiation Facility (IRRAD) is a well-established reference facility for conducting such experiments. Over the years, the IRRAD facility has developed a dedicated software infrastructure to support the control and monitoring systems used to manage these experiments, as well as to handle other important aspects such as dosimetry, spectrometry, and material traceability. In this paper, new developments and upgrades to the IRRAD software infrastructure are presented. These advances are crucial to ensure that the facility remains up-to-date and able to cope with the increasing (and always more complex) user needs. These software upgrades (some of them carried out within the EU-funded project AIDAinnova and EURO-LABS) will help to improve the efficiency and accuracy of the experiments performed at IRRAD and enhance the capabilities of this facility.

TUPDP103	Interlock Super Agent : Enhancing Machine Efficiency and Performance at CERN’s Super Proton Synchrotron	operation, software, diagnostics, controls	799
	E. Veyrunes, A. Asko, G. Trad, J. Wenninger CERN, Meyrin, Switzerland
	In the CERN Super Proton Synchrotron (SPS), finding the source of an interlock signal has become increasingly unmanageable due to the complex interdependencies between the agents in both the beam interlock system (BIS) and the software interlock system (SIS). This often leads to delays, with the inefficiency in diagnosing beam stops impacting the overall performance of the accelerator. The Interlock Super Agent (ISA) was introduced to address this challenge. It traces the interlocks responsible for beam stops, regardless of whether they originated in BIS or SIS. By providing a better understanding of interdependencies, ISA significantly improves machine efficiency by reducing time for diagnosis and by documenting such events through platforms such as the Accelerator Fault Tracking system. The paper will discuss the practical implementation of ISA and its potential application throughout the CERN accelerator complex.

The control system’s functionality and performance are vital for the accelerator’s reliability, stability, and efficiency. The PW laser accelerator control system has a three-layer distributed architecture, including device control, front-end (input/output) control and central control (data management, and human-machine interface) layers. The software platform primarily uses EPICS, supplemented by PLC, Python, and Java, while the hardware platform comprises industrial control computers, servers, and private cloud configurations. The control system incorporates various subsystems that manage the laser, target field, beamline, safety interlocks, conditions, synchronization, and functionalities related to data storage, display, and more. This paper presents a control system implementation suitable for laser accelerators, providing valuable insights for future laser accelerator control system development.
