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..

Conceptual design study for a dedicated low-energy diagnostics line at Linac3
/ Bellodi, Giulia (CERN) ; Bodart, Dominique (CERN) ; Cravero, Jean-Marc (CERN) ; Etxebarria Erdoiza, Jone (CIEMAT - Centro de Investigaciones Energéticas Medioambientales y Tec.

A low-energy diagnostics upgrade of Linac3 has been studied in the last couple of years to allow a more precise characterization of the beam properties at extraction from the source, currently impeded by a complete lack of measuring devices in the first ~6 m of the accelerator layout. [...]

Advancements in injection efficiency modelling for the Low Energy Ion Ring (LEIR) at CERN
/ Biancacci, Nicolo (CERN) ; Bodart, Dominique (CERN) ; Bellodi, Giulia (CERN) ; Bozzolan, Michele (CERN) ; Madysa, Nico (CERN) ; Meruga, Phani Deep (CERN) ; Alemany-Fernandez, Reyes (CERN) ; Scrivens, Richard (CERN)
The performance of the Low Energy Ion Ring (LEIR) at CERN is mainly determined by the number of charges extracted from the machine and transferred to the downstream chain of accelerators. While the required target of 9e10 charges has now been surpassed, a series of studies have been undertaken to further push the intensity reach of LEIR. [...]
