CERN PS Booster Upgrade Working Group

The LHC Injectors Upgrade (LIU) should plan for delivering reliably to the LHC the beams required for reaching the goals of the high luminosity LHC (HL-LHC). This includes LINAC4, the PS Booster, the PS, the SPS, as well as the heavy ion chain.

Within the LIU project the PS Booster upgrade project (“LIU-PSB”) coordinates all activities related to an upgrade of the PS Booster in order to deliver ultimate LHC beams. This had included the study of two scenarios to replace the PS Booster by a new PS injector : PSB Energy Upgrade and Rapid Cycling Synchroton (RCS). In August 2011, it was decided not to go further in the RCS study (a link to the study remain here), and to go for the PSB Energy Upgrade.

Mandate: Study of an Energy Upgrade of the CERN PS Booster

Study leader: K. Hanke, BE/OP

The aim of the study is to evaluate the technical feasibility of an increase in beam energy of the CERN PS Booster from presently 1.4 GeV to about 2 GeV as proposed at the Chamonix 2010 workshop.

The study comprises:

• Confirm the potential gain in terms of intensity and brilliance for LHC-type beams as presented at the Chamonix 2010 workshop.

• Confirm the technical feasibility. Identify accelerator components and equipment that need to be upgraded or exchanged. Identify potential showstoppers and point out solutions. Assign the responsible groups/units. Provide first rough time estimates for the various interventions needed.

• Provide a first estimate of material and personnel resources needed to complete the upgrade. Draft a project break-down into work packages, in preparation for a project to be launched by the director of accelerators.
