Induction synchrotron. III. Rapid cycle synchrotron and slow cyclesynchrotron. (Hardware components for the upgrade of KEK 12 GeV PS)

摘要

A technique of super-bunch acceleration with high repetitioninduction accelerators and an accumulator ring (AR) are required for theupgrade of the 12 GeV proton synchrotron at KEK. A fast dynamicswitching of 3 kV flip-flop pulses was performed at 200 kHz withSI-thyristors, to confirm a barrier bucket scheme for inductionacceleration. On the other hand, a model permanent gradient magnet forthe AR was assembled to investigate its field quality, temperaturedependence and compensation
