E-Beam Triode for Multiple Submicrosecond Pulse Operation

Abstract

Externally controlled diffuse discharge switches offer the potential of submicrosecond opening time and high repetition rate. For the investigation of an electron-beam controlled diffuse discharge, an e-beam gun was constructed which allows submicrosecond, multiple pulse operation. The 200 kV, 100 cm2, e-beam with thermionic cathode is designed as a triode. The control grid is pulsed to generate several successive e-beam pulses of ~100 ns duration and variable pulse-to-pulse interval. Electrical and optical diagnostics are used to monitor the triode performance. Preliminary switch experiments in N2-02 gas mixtures are discussed.
