Abstract

A series of liquid-metal-cathode vacuum-arc valves, suitable for high-power conversion and switching, has been developed (Eckhardt, 1972a, 1977; Eckhardt and Eckhardt, 1978). Their performance combines the most desirable properties of classical liquid-metal arc devices (such as ignitrons and multi-gap, multi-anode mercury valves) with those of classical (solid-cathode) vacuum-arc devices (such as triggered vacuum gaps and vacuum interrupters). In all versions of this type of valve (termed the Liquid-Metal Plasma Valve or LMPV), the cathode is force-fed with liquid metal, in proportion to current demand, at a rate corresponding to an electron-to-atom emission ratio of typically 50 to 100 (Eckhardt, 1969, 1970).
