Abstract
An improved gas discharge trigger for a pseudogap cold cathode thyratron. Electrical trigger pulses are capacitively coupled through the vacuum envelope wall (16) causing a gas discharge adjacent to the rear of the hollow cathode (26). Coupling apertures (12) between the trigger discharge region and the hollow cathode allow ionization to propagate into the rear of the hollow cathode and trigger the pseudogap from a non conducting to conducting state.
