Abstract

The authors have developed a magnetic-pulse-compression type solid-state pulse power supply. The lifetime of a solid-state device is expected to be much longer than that of a thyratron. Two parallel connected gate-turn-off thyristors generated a long pulse, which was compressed to 0.27 microsecond(s) ec by a three-stage magnetic pulse compression circuit. The average power of 8.2 kW was able to be obtained when a dummy load was connected instead of copper vapor laser (CVL). This pulse power supply has been applied to a CVL with a plasma tube of 70 mm inner diameter and 1.5 m discharge length, and has been successfully operated.
