Gigawatt All Solid State FID Pulsers with Nanosecond Pulse Duration

A new series of high voltage pulse generators with amplitude from 100 kV to 1 MV, pulse duration from 1 ns to 100 ns has been developed. FID all solid state switches manufactured by FID GmbH are used as main switches. At amplitude of 100-300 kV rise time can be 100-300 ps, at 1 MV rise time is about 1 ns. Timing jitter in all pulsers is less than 50 ps. Possible repetition rates are up to 1 kHz in continuous mode. Pulse generators are designed to operate into load of 25-250 Ohm peak power can be from hundreds of megawatts to 20 GW. The pulsers are very compact and efficient. For testing of pulsers high voltage loads and directional couplers with time resolution of better than 100 ps were developed. The pulsers can operate using both internal and external triggering, output amplitude can be adjusted in range from 20 to 100% of maximum voltage. It is possible to install PC interface to allow remote control over amplitude and triggering. Dimensions of pulse generators with maximum amplitude of up to 200 kV are approximately 500 times 500 times 160 mm, weigh it about 30 kg. 1 MV pulser has dimensions of 1000 times 500 times 200 mm, weight is about 50 kg when the average power is about 1-3 kW.
