Control Design Optimisations of Robots for the Maintenance and Inspection of Particle Accelerators / Díaz Rosales, Alejandro (CERN ; Delft Tech. U.) ; Di Castro, Mario (CERN) ; Gamper, Hannes (CERN ; Linz U.)
Automated maintenance and inspection systems have become increasingly important over the last decade for the availability of the accelerators at CERN. This is mainly due to improvements in robotic perception, control and cognition and especially because of the rapid advancement in artificial intelligence. [...]

Protection Layers Design for the High Luminosity LHC Full Remote Alignment System / Fernández Adiego, Borja (CERN) ; Blanco Viñuela, Enrique (CERN) ; Germinario, Andrea (CERN) ; Mainaud Durand, Helene (CERN) ; Sosin, Mateusz (CERN)
The Full Remote Alignment System (FRAS) is a complex measurement, alignment and control system designed to remotely align components of the Large Hadron Collider (LHC) following its High Luminosity upgrade. The purpose of FRAS is to guarantee optimal alignment of the strong focusing magnets and associated components near the experimental interaction points, while at the same time limiting the radiation dose to which surveyors in the LHC tunnel are subjected.

HydRA: A System-on-Chip to Run Software in Radiation-Exposed Areas / Gingold, Tristan (CERN) ; Arias Vázquez, A (CERN) ; Daniluk, Grzegorz (CERN) ; Rizzi, Mattia (PSI, Villigen) ; Serrano, Javier (CERN) ; Włostowski, Tomasz (CERN)
In the context of the High-Luminosity LHC project at CERN, a platform has been developed to support groups needing to host electronics in radiation-exposed areas. This platform, called DI/OT, is based on a modular kit consisting of a System Board, Peripheral Boards and a radiation-tolerant power converter, all housed in a standard 3U crate. [...]

Controls Optimization for Energy Efficient Cooling and Ventilation at CERN / Monteiro, Diogo (CERN) ; Barillère, Renaud (CERN) ; Bunijevac, Nikolina (CERN) ; Rühl, Ingo (CERN)
Cooling and air conditioning systems play a vital role for the operation of the accelerators and experimental complex of the European Organization for Nuclear Research (CERN). Without them, critical accelerator machinery would not operate reliably as many machines require a fine controlled thermodynamic environment. [...]

An Update on the CERN Journey from Bare Metal to Orchestrated Containerization for Controls / Oulevey, Thomas (CERN) ; Copy, Brice (CERN) ; Locci, Frank (CERN) ; Page, Stephen (CERN) ; Rocha, R (CERN) ; Roderick, Chris (CERN) ; Vanden Eynden, Marc (CERN) ; de Martel, Jean-Baptiste (CERN)
At CERN, work has been undertaken since 2019 to transition from running Accelerator controls software on bare metal to running in an orchestrated, containerized environment. This will allow engineers to optimise infrastructure cost, to improve disaster recovery and business continuity, and to streamline DevOps practices along with better security. [...]

Design of the Control System for the CERN PSB RF System / Landré, David (CERN) ; Brischetto, Ylenia (CERN) ; Haase, Matthias (CERN) ; Niccolini, Marco (CERN)
The RF system of the CERN PS Booster (PSB) has been renovated to allow the extraction energy increase and the higher beam intensities required by the LHC Injectors Upgrade (LIU) project. It relies on accelerating cells installed in three straight sections of each of the four accelerating rings of PSB. [...]

Spark Activity Monitoring for LHC Beam Dump System / Durmus, Can Berk (CERN) ; Carlier, Etienne (CERN) ; Magnin, Nicolas (CERN) ; Mottram, Timothy (CERN) ; Senaj, Viliam (CERN)
LHC Beam Dump System is composed of 25 fast-pulsed magnets per beam to extract and dilute the beam onto an external absorber block. Each magnet is powered by a high voltage generator to discharge the energy stored in capacitors into the magnet by using high voltage switches. [...]

CERN Proton Irradiation Facility (IRRAD) Data Management, Control and Monitoring System Infrastructure for post-LS2 Experiments / Gkotse, Blerina (CERN ; Paris, Ecole des Mines) ; Jouvelot, Pierre (Paris, Ecole des Mines) ; Pezzullo, Giuseppe (CERN) ; Ravotti, Federico (CERN)
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.
