Abstract :
A technique of super-bunch acceleration with high repetition induction accelerators and an accumulator ring (AR) are required for the upgrade of the 12 GeV proton synchrotron at KEK. A fast dynamic switching of 3 kV flip-flop pulses was performed at 200 kHz with SI-thyristors, to confirm a barrier bucket scheme for induction acceleration. On the other hand, a model permanent gradient magnet for the AR was assembled to investigate its field quality, temperature dependence and compensation
