Description
CERN has recently built the Large Hadron Collider (LHC), a superconducting circular particle accelerator designed for colliding two proton beams at 7 TeV energy. In order for the LHC to achieve ultimate beam parameters, CERN has launched a long-term program for the progressive replacement or upgrade of the old chain of accelerators presently used as injectors for the LHC, the so-called LHC Injectors Upgrade (LIU) project, and Linac4 is the first element of this program. Linac4 is a linear accelerator for negative hydrogen ions, which will replace the old Linac2 as linear injector for the CERN PS Booster. The 160 MeV H- beam from Linac4 will be injected into the 4 superimposed rings of the PS Booster by means of charge-exchange injection using, for each PSB ring, a set of 4 pulsed dipole magnets creating the required injection bump. A carbon stripping foil in the injection region will convert the H- beam to H+. The presentation gives an introduction to the plans for the upgrade of the PS Booster within the LIU project with focus on the modification of the injection region.
