Constraint-Based Optimization of Particle Routing and Accelerator Utilization
/ Irannejad, Farhad (CERN) ; Kain, Verena (CERN) ; Huschauer, Alexander (CERN) ; Kruk, Grzegorz (CERN)
This paper presents a constraint optimization model, implemented with CP-SAT, for static, cyclic particle beam scheduling in CERN’s accelerator complex. The formulation enforces hard constraints on beam shapes, sets of discrete basic periods (1.2 second intervals) across multiple accelerators, together with strict limits on beam repetitions per super-cycle, and particle accelerator non-overlap to prevent resource conflicts. [...]

Beam delivery of high-energy ion beams for irradiation experiments at the CERN Proton Synchrotron
/ Johnson, Eliott (CERN) ; Waets, Andreas (CERN) ; Imesch, Gil (CERN) ; Bilko, Kacper (CERN) ; Delrieux, Marc (CERN) ; Fraser, Matthew (CERN) ; Emriskova, Natalia (CERN) ; Arrutia Sota, Pablo Andreas (CERN) ; Garcia Alia, Ruben (CERN) ; Bass, Thomas (CERN)
Heavy-ion single event effect (SEE) test facilities are critical in the development of microelectronic components that will be exposed to the ionizing particles present in the hostile environment of space. CHARM High-energy Ions for Micro Electronics Reliability Assurance (CHIMERA) and HEARTS have developed a high-energy ion beam capable of scanning a wide range of Linear Energy Transfer (LET) at low intensities to study ionization effects on space-bound technology using CERN's Proton Synchrotron (PS).

ENUBET: A monitored neutrino beam for high precision cross section measurements
/ Torti, Marta (INFN, Milan Bicocca) ; Acerbi, Fabio (Fond. Bruno Kessler, Trento) ; Angelis, Ioannis (Aristotle U., Thessaloniki) ; Bomben, Luca (Insubria U., Como ; INFN, Milan Bicocca) ; Bonesini, Maurizio (INFN, Milan Bicocca) ; Bramati, Filippo (INFN, Milan Bicocca ; Milan Bicocca U.) ; Branca, Antonio (INFN, Milan Bicocca ; Milan Bicocca U.) ; Brizzolari, Claudia (INFN, Milan Bicocca ; Milan Bicocca U.) ; Brunetti, Giulia (INFN, Milan Bicocca ; Milan Bicocca U.) ; Calviani, Marco (CERN) et al.
The main source of systematic uncertainty on neutrino cross section measurements at the GeV scale is represented by the poor knowledge of the initial flux. The goal of cutting down this uncertainty to 1% can be achieved through the monitoring of charged leptons produced in association with neutrinos, by properly instrumenting the decay region of a conventional narrow-band neutrino beam.

The CERN SPS Low Level RF feedback with amplitude and frequency modulation
/ Hagmann, Gregoire (CERN) ; Spierer, Arthur (CERN) ; Egli, Julien (CERN) ; Baudrenghien, Philippe (CERN)
The CERN SPS Low Level RF (LLRF) has undergone a major upgrade, including the complete redesign of the 200 MHz Cavity-Controllers [1,2] and the Beam-Control [3]during the Long Shutdown two (LS2) in 2018-21. Two major goals motivated the upgrade, first the required doubling of the proton beam intensity injected from the Super Proton Synchrotron (SPS) for the High Luminosity Large HadronCollider (HL-LHC) project, second the implementation of the slip-stacking of two families of ions bunches, 100 ns spacing, to generate a 50 ns spacing after interleaving.

Overview of the radiation levels in the CERN accelerator complex after LS2
/ Canesse, Auriane (CERN) ; Zimmaro, Alessandro (CERN) ; Prelipcean, Daniel (CERN) ; Ricci, Daniel (CERN) ; Di Francesca, Diego (CERN) ; Lerner, Giuseppe (CERN) ; Garcia Alia, Ruben (CERN) ; Danzeca, Salvatore (CERN)
The PSB, PS, and SPS accelerators at CERN provide high-energy proton and ion beams to a wide range of experiments, from fixed targets to the world’s biggest particle accelerator: the Large Hadron Collider (LHC). In 2021 and 2022, their beams have reached unprecedented intensities thanks to the LHC Injectors Upgrade (LIU) undertaken during the Long Shutdown 2 (LS2) in preparation of the High-Luminosity (HL) LHC era.

Dual-scattering foil installation at CLEAR
/ Robertson, Cameron (Oxford U.) ; Aksoy, Avni (Ankara U.) ; Bateman, Joseph (Oxford U.) ; Corsini, Roberto (CERN) ; Dosanjh, Manjit (CERN) ; Farabolini, Wilfrid (CERN) ; Gerbershagen, Alexander (Groningen U.) ; Korysko, Pierre (Oxford U.) ; Latina, Andrea (CERN) ; Malyzhenkov, Alexander (CERN) et al.
The CLEAR facility at CERN allows users to receive an electron beam with energy up to 200 MeV, allowing flexibility in intensity, beam size and bunch structures. Separate from the main CERN accelerator complex, it is capable of hosting numerous experiments with rapid installations at two test stands.It would be highly desirable for many applications, but particularly those of a medical nature, to be able to provide a ‘flat’ beam at CLEAR, with a uniform intensity distribution over a significant component of its transverse dimensions.

Ion-motion simulations of a plasma-wakefield experiment at FLASHForward
/ Kalvik, D (U. Oslo (main)) ; Drobniak, P (U. Oslo (main)) ; Peña, F (U. Oslo (main) ; LMU Munich (main)) ; Lindstrøm, C A (U. Oslo (main)) ; Beinortaite, J (DESY) ; Boulton, L (DESY) ; Caminal, P (DESY) ; Garland, J (DESY) ; Loisch, G (DESY) ; Svensson, J Björklund (DESY) et al.
In plasma-based acceleration, an ultra-relativistic particle bunch$\unicode{x2014}$or an intense laser beam$\unicode{x2014}$is used to expel electrons from its propagation path, forming a wake that is devoid of electrons. The ions, being significantly more massive, are often assumed to be stationary. [...]
