Abstract

The design and initial operation of an advanced multi-gap pseudospark device is presented. Forced grading of the intermediate electrodes in the switch will be achieved by taps on the charging transformer. Gap synchronization is aided by UV illumination of all gaps from the primary gap trigger. Initial switch operation in triggered and self breakdown modes and the resulting rise times is evaluated. The switch is intended to be the critical part of a 500 kV, 10 kA, 200 ns transmission line transformer based pulse generator.
