Abstract:This paper summarizes recent results of the study and development of high-power repetitive nanosecond generators employing a semiconductor opening switch(SOS). The SOS-based pulsed power generator(SPG200, SPG700) has been developed and tested in Northwest Institute of Nuclear Technology. Some applications are carried out on the SOS-based generator, such as the high-frequency diode, research of long lifetime cathode, insulating research of breakdown. An experimental system of foilless diode with low guiding magnetic field is designed on the generator S-5N. The SPG200 delivers pulses with FWHM of 35 ns and amplitude up to 200 kV at 2 kHz repetition rate into a load in burst mode. The average output power is 13 kW. The generator can work at 300 Hz continuously. The SPG700 is designed by the same technique. The output specifications of the generator are as follows: output voltage 700 kV, output current 5 kA, pulse duration(FWHM) 40 ns. Now the generator is being tested, which delivers pulses with 660 kV,4.4 kA, 70 ns(FWHM) on the resistance load.
Keywords:Semiconductor opening switch(SOS)  Pulse power  Magnetic pulse compressor  High power electron beams
