Kickers used for bunched e/sup +//e/sup -/ beam transfer in the CERN PS complex

Abstract

The main characteristics and operating experiences of the 100-Hz pulsed injection kicker and the eight pulse burst ejection kicker systems installed in the EPA (Electron Positron Accumulator) ring are described. Delay line type magnets placed in vacuum tanks are excited by fast pulses generated from thyratron-switched PFNs (pulse forming networks). Deflecting fields of 52 ns FWHH with rise and fall times of 28 ns are achieved. Up to eight e/sup +/ or e/sup -/ bunches are injected into the PS (Proton Synchrotron) in a single turn. For each particle type, one delay-line-type magnet is used. Both magnets are excited from the same PFN, switched at either end, with a pulse of 2000 A and 2 mu s duration. A transfer efficiency between EPA and PS exceeding 90% has been achieved.<>
