PSB Half Sector Test

The LHC Injectors Upgrade (LIU) program for the PSB (LIU-PSB project) comprises two parts, the connection to Linac4, CERN's future linear accelerator, and the increase of the PSB extraction energy from 1.4 to 2 GeV.

Linac4 will deliver an H- beam at 160 MeV to the PSB compared to the current 50 MeV proton beam from Linac2. The H- charge-exchange injection process will make use of a stripping foil installed in a new injection chicane to produce the required protons for the PSB rings. In addition, it will be possible to paint horizontally the phase space with the help of four kicker magnets ('painting bump').

The H- charge-exchange injection principle is new for CERN and involves many challenges, which could lead to long run-in times after LS2 and the risk of beam quality issues. Also the technical implementation of the future PSB injection section in a very restricted space and for the four PSB rings represents quite some risks in terms of installation duration and integration. As risk mitigation strategy it has therefore been proposed to install parts of the future PSB injection equipment in the Linac4 transfer line to be able to run tests with 160 MeV protons from Linac4 during 2016.
