Abstract :
Stacked Blumlein pulsers have produced high power waveforms with fast risetimes and a wide range of pulse durations and peak values using conventional thyratrons or spark gaps. This paper details the authors´ recent efforts to operate these pulsers with GaAs photoconductive switches in the avalanche mode. Adaptation of the design and fast charging schemes have enabled the stacked Blumleins to produce high-power nanosecond pulses with risetimes on the order of 200-300 ps. Significant progress is reported toward realizing an intense, pulse power source for ultra-wideBand HPM devices operating at 100 MW levels of power and kiloHertz repetition rates
