Initial Results from Experiments with a Reflex Triode Powered by a Marx Generator

The reflex triode is a device used for the generation of high-power microwave (HPM) radiation. This study presents an experimental investigation of a reflex triode, powered by a 400 kV Marx generator, and also gives a comparison between theoretically and experimentally obtained scaling laws. The experimentally determined dominating frequency from the reflex triode with different anode-cathode gaps agree qualitatively well with the theoretical expression, but in general the experimental frequency is lower.
