UPGRADES FOR THE CERN PSB-TO-PS TRANSFER AT 2 GEV

摘要

The CERN PS Booster extraction energy will be upgraded from 1.4 to 2.0 GeV to alleviate the direct space charge tune shift in the PS. The focussing structure of the transfer line will be modified in order to better match the optics between the PSB and the PS. The optics of the PS at injection and, with it, of the transfer line can be adapted to reduce the continuous losses from the already injected and circulating beam bumped towards the septum. Experimental results of the optics optimisation and probing the injection kicker flat top are shown. Modifications of the recombination septa and the main horizontal bending magnet in the measurement line are presented.
