Development of Pulsed Power Modulator for Induction Synchrotron

摘要

A pulsed power modulator for the POP experiment of an induction synchrotron has been developed. Various difficulties in the development of the modulator, such as enormous power dissipation at a MOSFET, the resonant ringing in the output waveform, the isolation from the ground potential, and the incorrect action of a gate driving circuit, have been discussed and solved. The developed power modulator is installed into the existing accelerator, KEK 12-GeV proton synchrotron. The POP experiment of the induction sychrotron has been successfully conducted. A single RF bunch injected from the 500-MeV booster ring was accelerated to the flat-top energy of 8 GeV.
