High voltage pulse generators for kicker magnet excitation

Describes three new pulse generator systems for the excitation of the kicker magnets of fast ejection facilities. Firstly a pulse generator for the fast ejection from the 28 GeV proton synchrotron (CPS) of any desired number of the twenty circulating proton bunches is treated. Secondly the paper describes the development of a pulse generator for the transfer at 50 mu sec intervals of single bunches of the proton beam from the CPS to the new 300 GeV machine (SPS) in construction at CERN. Finally the development of a programmable eleven step pulse generator for the CPS/SPS transfer is described. This generator allows the shaving of the CPS beam during eleven turns, and because of the CPS/SPS diameter ratio, allows the SPS to be uniformly filled. (7 refs)
