| Abstract: | 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. © 2008 Wiley Periodicals, Inc.
