Following the successful completion of the LHC Injectors Upgrade (LIU) project, since 2021 the Proton Synchrotron (PS) Booster has served the LHC injector chain with protons at an increased kinetic energy of 2 GeV. An upgrade of the ISOLDE (Isotope Separator On-Line DEvice) facility has long been considered to produce radioactive ion beams with a higher energy proton driver beam. [...]

Two-Dimensional Longitudinal Painting at Injection into the CERN PS Booster
/ Albright, Simon (CERN) ; Asvesta, Foteini (CERN) ; Bielawski, Bartosz Przemyslaw (CERN) ; Bracco, Chiara (CERN) ; Skowroński, Piotr (CERN) ; Wegner, Rolf (CERN)
To inject highest beam intensities at the transfer from Linac4 into the four rings of the PS Booster (PSB) at CERN, protons must be accumulated during up to 148 turns in total. With the conventional, fixed chopping pattern this process results in an approximately rectangular distribution in the longitudinal phase space. [...]

Shaping High Brightness and Fixed Target Beams with the CERN PSB Charge Exchange Injection
/ Bracco, Chiara (CERN) ; Albright, Simon (CERN) ; Asvesta, Foteini (CERN) ; Di Giovanni, Gian Piero (CERN) ; Roncarolo, Federico (CERN)
CERN adopted the charge exchange injection technique for the first time in the PS Booster after Long Shutdown 2. This allowed to overcome space charge limitations, tailor high brightness beams for the LHC and deliver high intensity flux of protons to the fixed target experiments. [...]

2022 has been a performance consolidation year for the Low Energy Ion Ring (LEIR) at CERN that demonstrated its capability of delivering the target beam parameters required for high luminosity production in the LHC in a reproducible and reliable way. The main steps that have led to the high performance reach of this beam, together with the machine stability improvements deployed, are detailed in this paper..
