“…Specifically, a new method has been offered in place of the conventional confinement and acceleration of charged particles in the beam (longitudinal) direction using an RF electric field. In IS, charged particles are confined by a pulsed electric field generated by a cavity [2], thus producing a very long beam of microsecond order referred to as a super-bunch. In addition, acceleration is performed by means of a long-flat-top pulsed field generated by another cavity.…”

SUMMARYA 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.

Recently the first induction acceleration of a single proton bunch of 2.3E10ppp was demonstrated [1], where it was accelerated from 500MeV to 8GeV in 1.9sec in KEK-PS. This paper describes the induction system for a synchrotron and a beam confinement experiment as a second step of the proof-of principle (PoP) experiments of a "induction synchrotron" [2], where a proton beam with a bunch length of 500ns was longitudinally confined by the induction barriers for 500msec, is introduced..
