/ 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..

Schottky Signal From Distributed Orbit Pick-Ups
/ Marqversen, Ole (CERN) ; Jensen, Steen (CERN)
In the CERN Extra Low ENergy Anti-proton (ELENA) ring, intended for the deceleration of antiprotons, the longitudinal Schottky signal is obtained by summing the multiple electrostatic pick-up (PU) signals that are also used to measure the closed orbit. The signals from the individual PUs are phase-compensated to a single, common longitudinal location in the machine and added in the time domain. [...]

ELENA Commissioning and Status
/ Carli, Christian (CERN) ; Angoletta, Maria Elena (CERN) ; Bartmann, Wolfgang (CERN) ; Bojtár, Lajos (CERN) ; Butin, Francois (CERN) ; Dupuy, Bruno (CERN) ; Dutheil, Yann (CERN) ; Fraser, Matthew (CERN) ; Freyermuth, Pierre (CERN) ; Gamba, Davide (CERN) et al.
The Extra Low ENergy Antiproton ring ELENA is a small synchrotron recently constructed and commissioned to decelerate antiprotons injected from the Antiproton Decelerator AD with a kinetic energy of 5.3 MeV down to 100 keV. Controlled deceleration in the synchrotron, equipped with an electron cooler to reduce losses and generate dense bunches, allows the experiments, typically capturing the antiprotons in traps and manipulating them further, to improve the trapping efficiency by one to two orders of magnitude.

The Orbit Measurement System for the CERN Extra Low Energy Antiproton Ring
/ Marqversen, Ole (CERN) ; Angoletta, Maria Elena (CERN) ; Jaussi, Michael (CERN) ; Marco-Hernandez, Ricardo (Valencia U., IFIC) ; Molendijk, John (CERN) ; Ruffieux, Romain (CERN) ; Sanchez-Quesada, Jorge (CERN) ; Søby, Lars (CERN)
The CERN Extra Low ENergy Antiproton ring (ELENA) intended to decelerate anti-protons from the CERN Antiproton Decelerator from 100Mev/c to 13.7MeV/c, has been equipped with an orbit measurement system consisting of 10 horizontal and 10 vertical electrostatic pick-ups. Using charge amplifiers the signals are converted into sum and difference signals that, once digitalized, are down converted to baseband and used to calculate intensity independent beam positions.
