Abstract

This study focuses on the characterization of a spark gap closing switch used by AWE in their Mogul-D and other pulsed power facilities at Aldermaston. The switch is a dc-charged, three-electrode spark gap. The effect of the polarity and magnitude of the charging voltage is investigated. Aspects of switching performance have also been investigated using a 10-stage Marx generator, capable of producing output pulses in the region of 750 kV. A D-dot field probe, flush-mounted in the earth electrode of the switch, is used as a diagnostic to monitor the switching characteristics.
