Design and performance of the DARHT second axis accelerator

The Dual-Axis Radiographic Hydrodynamic Test Facility (DARHT) at Los Alamos National Laboratory consists of two linear induction accelerators at right angles to each other. The First Axis, operating since 1999, produces a nominal 20-MeV, 2 kA single pulse with 60 ns width. In contrast, the DARHT Second Axis produces up to four pulses in a variable pulse… (More)
