High Average Power Tests of a Crossed-Field Closing Switch

Abstract

A triode version of the crossed-field closing switch (CFCS) has been successfully tested at average powers of up to 800 kW (40 kA, 40 kV, 12 microsecond pulse width at 80Hz) for burst durations of 30 s. Unlike most conventional spark gaps, the arc is initiated from a crossed-field glow discharge and occurs at random locations on a shot-to-shot basis. This uniformly disperses the heat loading and erosion over a relatively large electrode surface area which may then be cooled.
