Large area, high reliability liquid dielectric systems: provisional design criteria and experimental approaches to more realistic projections

In the Electra program a number of candidate designs have been developed for pulsed power systems to drive KrF lasers in an inertial confinement fusion power plant All use coaxial 1.5 MV water energy stores and oil insulation; most use oil-insulated magnetic switches. The largest design, a three-stage magnetic pulse compressor, where the regions of highly-stressed electrodes in the water and oil are indicated. There will be of the order of 200 such modules in a power plant.
