Beam coupling impedance of the main extraction kickers in the CERN PS / Neroni, M (CERN ; U. Rome La Sapienza (main)) ; Barnes, M J (CERN) ; Lasheen, A (CERN) ; Mostacci, A (U. Rome La Sapienza (main)) ; Popovic, B (Argonne) ; Vollinger, C (CERN)
In view of the High Luminosity (HL) upgrade of the LHC, thebeam intensity must be doubled in the injector chain. To performreliable beam dynamics simulations, the beam coupling impedance inthe injectors, such as the Proton Synchrotron (PS), must be followedclosely by including all contributing elements into the impedancemodel.

Characterisation of the n_TOF 20 m beam line at CERN with the new spallation target / n_TOF Collaboration
The n_TOF facility hosts CERN’s pulsed neutron source, comprising two beam lines of different flight paths and one activation station. It is based on a proton beam delivered by the PS accelerator impinging on a lead spallation target. [...]

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. [...]
