Modern physics experiments are frequently very complex, relying on multiple simultaneous events to happen in order to obtain the desired result. The experiment control system plays a central role in orchestrating the measurement setup: However, its development is often treated as secondary with respect to the hardware, its importance becoming evident only during the operational phase.

Beam gas curtain monitor: Vacuum studies for LHC integration and operation
/ Castro Sequeiro, C (CERN) ; Ady, M (CERN) ; Bregliozzi, G (CERN) ; Chatzigeorgiou, N (CERN) ; Churchman, A R (CERN) ; Kersevan, R (CERN) ; Lefevre, T (CERN) ; Mazzoni, S (CERN) ; Pigny, G (CERN) ; Rossi, A (CERN) et al.
A beam gas curtain (BGC) monitor has been designed to obtain information about the relative position between the LHC proton beam and the hollow electron lens electron beam through a minimally invasive process. Its working principle relies on intersecting the path of both beams with a supersonic gas curtain, introduced transversely into the LHC beamline, to produce a fluorescence signal. [...]

Mean transverse energy, surface chemical and physical characterization of CERN-made Cs-Te photocathodes
/ Jones, L B (Daresbury ; Cockcroft Inst. Accel. Sci. Tech.) ; Panuganti, H (CERN) ; Benjamin, C (Daresbury ; Warwick U.) ; Chevallay, E (CERN) ; Churn, H M (Daresbury ; Cockcroft Inst. Accel. Sci.

Sci. Tech. ; Liverpool U.)
Cesium telluride photocathodes are known to offer high quantum efficiencies under UV illumination combined with good lifetimes compared to other semiconductor photocathodes, making them very popular electron sources for particle accelerator applications. The development of photocathode preparation, characterization, and related expertise at a single accelerator laboratory can be challenging, expensive, and time consuming. [...]

CIRCUS: an autonomous control system for antimatter, atomic and quantum physics experiments
/ AEgIS Collaboration
A powerful and robust control system is a crucial, often neglected, pillar of any modern, complex physics experiment that requires the management of a multitude of different devices and their precise time synchronisation. The AEgIS collaboration presents CIRCUS, a novel, autonomous control system optimised for time-critical experiments such as those at CERN's Antiproton Decelerator and, more broadly, in atomic and quantum physics research. [...]

Design of a compact superconducting recoil separator for HIE-ISOLDE
/ Resta-López, J (Valencia U.) ; Foussat, A (CERN) ; Kirby, G (CERN) ; Rodin, V (CERN) ; Kirby, O (PSI, Villigen) ; Martel, I (Huelva U.) ; Welsch, C P (Cockcroft Inst. Accel. Sci. Tech. ; Liverpool U.)
The High Intensity and Energy ISOLDE facility (HIE-ISOLDE) at CERN has unprecedentedly expanded the research capabilities to investigate the structure of the atomic nucleus and the nuclear interaction. In this context, to meet the high-resolution mass spectroscopy required by the HIE-ISOLDE physics program, an innovative spectrometer is currently being designed, the ISOLDE Superconducting Recoil Separator (ISRS).

Beam lifetime monitoring using beam loss monitors during LHC Run 3
/ Morales Vigo, S (CERN ; Cockcroft Inst. Accel. Sci. Tech.) ; Salvachua, B (CERN) ; Welsch, C P (Cockcroft Inst. Accel. Sci. Tech.) ; Zamantzas, C (CERN) ; Wolfenden, J (Cockcroft Inst. Accel. Sci. Tech.) ; Hermes, P (CERN) ; Redaelli, S (CERN)
The Beam Loss Monitoring (BLM) system of the Large Hadron Collider (LHC) at CERN is essential for the protection of machine elements against energy deposition from beam losses. Employing around 4000 detectors placed around the 27-km LHC ring, the BLM system measures secondary particles continuously and can trigger beam extraction in less than 3 turns, in case the signals exceed certain predetermined thresholds.

Prospect of operating with limited skew quadrupole corrector availability in the LHC interaction regions
/ Soubelet, F (CERN ; Liverpool U.) ; Persson, T (CERN) ; Kostoglou, S (CERN) ; Tomás, R (CERN) ; Hostettler, M (CERN) ; Welsch, C P (Liverpool U.)
In the Large Hadron Collider (LHC), corrections of local Interaction Region (IR) linear coupling are of importance to control beam sizes at Interaction Points (IPs) and hence the luminosity performance, as well as to prevent a significant impact on the beam dynamics. During the LHC Run 3, the skew quadrupole corrector magnets used on either side of IPs are expected to exceed their radiation dose limit. [...]
