Pulsed Power Systems For The Darht Accelerators

The Dual-Axis Radiographic HydroTest (DARHT) Facility is being designed to produce high-resolution flash radiographs of hydrodynamics experiments. Two 16- to 20-MeV linear induction accelerators (LIA), with an included angle of 900, are used to produce intense bremsstrahlung x- ray pulses of short duration (60-ns flat-top). Each accelerator has a 4- MeV electron source that injects an electron beam into a series of 250- kV induction cells. The three major pulsed-power systems are the injectors, the induction-call pulsed-power (ICPP) units, and the ICPP trigger systems, and are discussed in this paper.
