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..

A New Electron Cooler for the CERN Antiproton Decelerator (AD) / Tranquille, G (CERN) ; Cenede, J (CERN) ; Frassier, A (CERN) ; Chritin, N S (CERN) ; Coutron, Y M (CERN) ; Sinturel, A (CERN) ; Ferreira, J A (CERN) ; von Freeden, L (CERN) ; Bajas, H (CERN) ; Jorgensen, L V (CERN)
The current electron cooler at the Antiproton Decelerator (AD) at CERN was built in the second half of the 1970s and is thus well over 40 years old. It was built for the Initial Cooling Experiment (ICE) where stochastic and electron cooling were tested to ascertain the feasibility of using these techniques to generate high intensity antiproton beams for the SPpS.

AD/ELENA Electron Cooling Experience During and after CERNs Long Shutdown (LS2) / Gamba, Davide (CERN) ; Bojtár, Lajos (CERN) ; Carli, Christian (CERN) ; Dupuy, Bruno (CERN) ; Frassier, Alexandre (CERN) ; Jørgensen, Lars (CERN) ; Ponce, Laurette (CERN) ; Tranquille, Gerard (CERN)
Electron cooling is a key ingredient of the Antimatter Factory at CERN, now composed of the AD and ELENA rings, both featuring an electron cooler. After the successful commissioning of the ELENA ring and electron cooling with antiprotons in 2018, the facility was shut down for the CERN long shutdown (LS2). [...]
