Solid-state kicker pulser for DARHT-2

Summary form only given, as follows. To replace a hard tube design, a solid-state kicker pulser for the Dual-Axis Radiographic Hydrodynamic Test facility (DARHT-2) has been designed and tested. This kicker modulator uses multiple solid-state modules stacked in an inductive-adder configuration where the energy is switched into each section of the adder by a parallel array of MOSFETs. The modulator features very fast rise and fall times, pulse width agility and a high pulse-repetition rate in burst mode. The modulator can drive a 50* load with voltages up to 20 kV and can be easily configured for either positive! or negative polarity. The presentation will include test and operational data.
