CROSSED-FIELD SWITCH TUBE

摘要

A crossed-field switch device which has anode, cathode and control electrodes which define a main gap and an ignition gap. The control electrode is connected through an impedance to one of the other electrodes to prevent hollow cathode discharge in the control gap. The control gap can be pulsed to ignite and the plasma passed through the intermediate electrode into the main gap to cause its ignition into the low pressure glow mode.
