Design and Development of a New ISOLDE Beam Dump / Martin Ruiz, Jose Maria
The CERN ISOLDE facility is currently equipped with two uncooled iron blocks acting as beam dumps. They were installed in 1991 and they are currently operating outside of the original design parameters. [...]

Status of E-Cooling Characterisation at 100 keV in ELENA / Gamba, Davide (CERN) ; Asvesta, Foteini (CERN) ; Kruyt, Peter (CERN ; Frankfurt U.) ; Ponce, Laurette (CERN) ; Russo, Giulia (CERN)
The Extra Low ENergy Antiproton ring (ELENA) ring at CERN was commissioned in 2018 and is in regular production operation from 2021. ELENA uses e-cooling for cooling pbar beams on two plateaus at 653 keV and 100 keV kinetic energy. [...]

H0 Diagnostics for the ELENA Electron Cooler / Tranquille, Gerard (CERN)
In addition to antiprotons, the ELENA ring at CERN can also inject protons and H⁻ ions from a dedicated ion source located close to the ring. These particles offer the possibility for extra diagnostics for detailed investigations into the cooling process at the very low energy of the ELENA ring. [...]

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.

Dynamic Aperture and Frequency Analysis in ELENA with Electron Cooler Magnetic Field Included / Bojtár, Lajos (CERN)
We present a new tracking algorithm and its implementation called SIMPA. It has the unique feature of long-term tracking of charged particles in arbitrary static electromagnetic fields in a symplectic way. [...]

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. [...]

A power amplifier based on rad-hard gallium nitride FETs for the 10 MHz cavities of the CERN proton synchrotron / Gnemmi, Giulia (CERN) ; Paoluzzi, Mauro (CERN) ; Energico, Salvatore (CERN) ; Desquiens, Valentin (CERN) ; Rossi, Carlo (CERN)
The upcoming High-Luminosity Large Hadron Collider (HL-LHC) program requires a beam performance in the CERN Proton Synchrotron (PS) that is at the limits of the current Radio-frequency (RF) systems. Following the discontinuation of the RF tube production of the driver amplifiers a new solid-state design has been developed using radiation-hard amplifier technology. [...]
