Measurements of beam correlations induced via coupled resonance crossing in the CERN PSB
/ Lamb, Elleanor (CERN ; Ecole Polytechnique, Lausanne) ; Asvesta, Foteini (CERN) ; Franchetti, Giuliano (Darmstadt, GSI) ; Sterbini, Guido (CERN) ; Bartosik, Hannes (CERN) ; Seidel, Mike (PSI, Villigen ; Ecole Polytechnique, Lausanne) ; Albright, Simon (CERN) ; Prebibaj, Tirsi (CERN)
Beam profile measurements in the LHC and its injector complex show heavy tails in both transverse planes. From standard profile measurements, it is not possible to determineif the underlying phase space distribution is statistically independent. [...]

Tail population studies in the CERN Proton Synchrotron
/ Bozatzis, Miltiadis (Aristotle U., Thessaloniki ; CERN) ; Asvesta, Foteini (CERN) ; Bartosik, Hannes (CERN) ; Huschauer, Alexander (CERN) ; Lasheen, Alexandre (CERN) ; Maclean, Ewen (CERN) ; Prebibaj, Tirsi (CERN) ; Van Goethem, Wietse (CERN)
The beam quality in terms of the transverse beam profiles from the CERN injectors plays a crucial role for the luminosity production at the LHC. Transverse tails beyond a Gaussian distribution have been observed in all the LHC injectors and efforts to optimize them are ongoing, as they can perturb operations due to large losses at LHC injection. [...]

A review of the 2023 antiproton physics run in the CERN antimatter factory
/ Bojtar, Lajos (CERN) ; Lefort, Bertrand (CERN) ; Dupuy, Bruno (CERN) ; Gamba, Davide (CERN) ; Joergensen, Lars (CERN) ; Ponce, Laurette (CERN) ; Freyermuth, Pierre (CERN) ; Pasinelli, Sergio (CERN) ; Dutheil, Yann (CERN)
Despite a shorter-than-scheduled physics run due to a hardware problem, the AD/ELENA antiproton complex delivered record beam intensities to the experiments during the 2023 run. This paper reviews the performance of both the CERN Antiproton Decelerator (AD) and the Extra Low ENergy Antiproton (ELENA) decelerator and their associated transfer lines. [...]

Shower simulations for the CERN proton synchrotron internal dump and possible shielding options
/ Niang, Samuel (CERN) ; Huschauer, Alexander (CERN) ; Esposito, Luigi Salvatore (CERN) ; Giovannozzi, Massimo (CERN) ; Pugnat, Thomas (CERN)
During the Long Shutdown 2, the two internal dumps were replaced and successfully integrated into the CERN Proton Synchrotron operation to withstand the intense and bright beams for the High-Luminosity LHC. They function as safety devices, designed to swiftly intersect the beam’s trajectory and effectively stop the beam over multiple turns. [...]

Recent updates in the impedance characterization of the CERN PS Booster Finemet RF system
/ Neroni, Michela (CERN ; Rome U.) ; Albright, Simon (CERN) ; Damerau, Heiko (CERN) ; Gnemmi, Giulia (CERN) ; Haase, Matthias (CERN) ; Mostacci, Andrea (Rome U.) ; Paoluzzi, Mauro (CERN) ; Vollinger, Christine (CERN)
During the last long shutdown of the accelerators at CERN (LS2), the main radio frequency system of the Proton Synchrotron Booster (PSB) was upgraded. A widebandsystem with Finemet magnetic alloy cavities driven by solid-state amplifiers replaced several different ferrite-loaded cavities. [...]
