Performance of the Low Energy Ion Ring at CERN with lead ions in 2022
/ Alemany-Fernandez, Reyes (CERN) ; Frassier, Alexandre (CERN) ; Rey, Anthony (CERN) ; Wetton, Chris (CERN) ; Mutin, Christophe (CERN) ; Gamba, Davide (CERN) ; Bodart, Dominique (CERN) ; Carlier, Felix (CERN) ; Velotti, Francesco (CERN) ; Le Godec, Gilles (CERN) et al.
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..

CERN’s digital Low-Level RF (LLRF) family for injectors is deployed on CERN’s PS Booster (PSB), Low Energy Ion Ring (LEIR), Extra Low ENergy Antiproton (ELENA) ring and Antiproton Decelerator (AD). It implements multiple capabilities, including beam and cavity feedback loops, bunch shaping, longitudinal blowup, bunch splitting and longitudinal diagnostics.New capabilities are now available and the LLRF family is soon going to be deployed for tests also in CERN’s Proton Synchrotron (PS).

Beam Commissioning of the New Digital Low-Level RF System for CERN’s AD
/ Angoletta, Maria Elena (CERN) ; Albright, Simon (CERN) ; Barrientos, Diego (CERN) ; Findlay, Alan (CERN) ; Jaussi, Michael (CERN) ; Rey, Anthony (CERN) ; Sumiński, Maciej (CERN)
CERN’s Antiproton Decelerator (AD) has been re-furbished to provide reliable operation for the Extra Low ENergy Antiproton ring (ELENA). In particular, AD was equipped with a new digital Low-Level RF (LLRF) system that was successfully commissioned during the summer 2021. [...]
