Switching power supply for the PFL kicker magnet

SI-thyristor is expected as a solid-state high power switching semi-conducting device for the kicker magnet in the circular accelerator. Current rise has reached to 100 kA//spl mu/s. We noticed this characteristic and tried the use it for the pulse forming line (PFL). Preliminary results of the proto-type power supply of 20 kV-120 ns, with various impedance, although the intention is 75 kV-100 ns, are presented.
