ABSTRACT:
A method is disclosed of operating a cold-cathode-cold-reservoir thyratron for laser/radar and other systems employing high voltage and current pulses using ZrVFe as the hydrogen thyratron material. According to the method, a hydride of ZrVFe is first formed and the hydrided material then placed in the cathode structure of the thyratron. The tube is then pumped down to its operating pressure of approximately 10.sup.-3 atmospheres, the hydrided material then acting as a ballast to maintain that partial pressure of hydrogen at room temperature.
