Abstract :
NICHICON (KUSATSU) CORPORATION and KEK have developed a novel long-pulse klystron modulator for both of single-beam tube (136 kVp*100 A) and multi-beam tube (120 kVp*140 A). The main features are; - crowbar-less system with optimized IGBT snubber circuit, - compact and highly reliable Self-Healing capacitors, - HV & LV twin pulse transformers of laminated steel core for reduced tank volume.
