(CERN) ; Bell, B. (TRIUMF ; McGill U., Montreal (main)) ; Bidinosti, C.P. (Winnipeg U. ; Manitoba U.) ; Bylinsky, Y. (TRIUMF) ; Chak, J. (TRIUMF) ; Das, M. (Manitoba U.) ; Davis, C.A. (TRIUMF) et al.
A fast-switching, high-repetition-rate magnet and power supply have been developed for and operated at TRIUMF, to deliver a proton beam to the new ultracold neutron (UCN) facility. The facility possesses unique operational requirements: a time-averaged beam current of 40~$\mu$A with the ability to switch the beam on or off for several minutes. [...]

Consolidation of the Power Trigger Controllers of the LHC Beam Dumping System / Strobino, Léa (CERN) ; Magnin, Nicolas (CERN) ; Voumard, Nicolas (CERN)
The Power Trigger Controller (PTC) of the LHC Beam Dumping System (LBDS) is in charge of the control and supervision of the Power Trigger Units (PTU), which are used to trigger the conduction of the 50 High-Voltage Pulsed Generators (HVPG) of the LBDS kicker magnets. This card is integrated in an Industrial Control System (ICS) and has the double role of controlling the PTU operating mode and monitoring its status, and of supervising the LBDS triggering and re-triggering systems.

SPS Beam Dump Enhancements on Tracking and Synchronization / Voumard, Nicolas (CERN) ; Magnin, Nicolas (CERN) ; Van Trappen, Pieter (CERN)
During Long Shutdown 2 (LS2) at CERN, the SPS Beam Dumping System (SBDS) was completely renovated and relocated to SPS Point 5. This allowed to deploy at the SPS the Beam Energy Tracking System (BETS) and the Trigger Synchronization Unit (TSU), initially designed for and operational at the LHC Beam Dumping System (LBDS).

The Embedded Monitoring Processor for High Luminosity LHC / Moschovakos, Paris (CERN) ; Ecker, Dominic (Wuppertal U.) ; Olesen, Jakob (Aarhus U.) ; Ryjov, Vladimir (CERN) ; Schlenker, Stefan (CERN)
The Embedded Monitoring Processor (EMP) is a versatile platform designed for High Luminosity LHC experiments, addressing the communication, processing, and monitoring needs of diverse applications in the ATLAS experiment, with a focus on supporting front-ends based on lpGBT (low power Giga-Bit Transceiver). Built around a commercial SoM, the EMP architecture emphasizes modularity, flexibility and the usage of standard interfaces, aiming to cover a wide range of applications and facilitating detector integrators to design and implement their specific solutions.

SAMbuCa: Sensors Acquisition and Motion Control Framework at CERN / Masi, Alessandro (CERN) ; Andreassen, Odd (CERN) ; Arruat, Michel (CERN) ; Danzeca, Salvatore (CERN) ; Di Castro, Mario (CERN) ; Donzé, Mathieu (CERN) ; Fargier, Sylvain (CERN) ; Ferraro, Rudy (CERN) ; Gulin, Marco (CERN) ; Kozsar, Ioan (CERN) et al.
Motion control systems at CERN often have challenging requirements, such as high precision in extremely radioactive environments with millisecond synchronization. These demanding specifications are particularly relevant for Beam Intercepting Devices (BIDs) such as the collimators of the Large Hadron Collider (LHC). [...]

Labview-Based Template for Enhanced Accelerator Systems Control: Software Solutions for the CERN-ISOLDE Facilities / Charrondière, Cedric (CERN) ; Andreassen, Odd (CERN) ; Benoit, Antoine (Unlisted, CH) ; Boorman, Gary (Unlisted, CH) ; Galetti, Elena (CERN) ; Heinke, Reinhard (CERN) ; Le, Line (CERN) ; Marsh, Bruce (CERN) ; Rossel, Ralf (CERN) ; Rothe, Sebastian (CERN) et al.
ISOLDE is part of the experimental infrastructure with-in the CERN accelerator complex that provides radioac-tive ion beams for studies of fundamental nuclear phys-ics, astrophysics, condensed matter physics and medical applications. Complementing the available controls in-frastructure, an easy-to-use set of applications was devel-oped to allow operators to record and display signals from multiple sources, as well as to provide drivers for non-standard, custom-made instruments and specialized off-the-shelf components.
