PBFA II is a 100 TW pulsed power accelerator constructed at Sandia National Laboratories for use in the light ion fusion program. The objective of PBFA II is to accelerate and focus upon an inertial confinement fusion (ICF) target a lithium beam with sufficient energy, power, and power density to perform ignition scaling experiments. The technologies used in PBFA II include: primary energy storage and compression with 6 MV, low-inductance Marx generators, pulse forming in water-insulated, water-dielectric lines with self-closing water switches, module synchronization using laser-triggered, 6 MV multistage gas switches, voltage addition in vacuum using self-magnetically-insulated biconic transmission lines, inductive energy storage and pulse compression using a fast-opening plasma erosion switch, beam formation using a magnetically-insulated ion diode, and space-charge and current-neutralized beam propagation to the target in a gas-filled cell. The first multimodule shot was on December 11, 1985.
