THE PROPOSED CERN PROTON-SYNCHROTRON UPGRADE PROGRAM

In the framework of the High-Luminosity LHC project, the CERN Proton Synchrotron (PS) would require a major upgrade to match the future beam parameters requested as pre-injector of the collider. The different beam dynamics issues, from space-charge limitations to longitudinal instabilities are discussed, as well as the proposed technical solutions to overcome them, covering the increase of the injection energy to RF related improvements.
