Book Description
The purpose of the 1989 NATO ARW was to develop applications for and an improved understanding of the physics for high current emission and conduction observed in hollow cathode-hollow anode switches including the pseudospark and back-lighted thyratron (BLT). New applications include highly emissive cathodes for microwave devices, accelerators and free electron lasers, high power tubes, electron and ion-beams, microlithography. accelerators, and other plasma devices. Recent research has produced this new generation of gas- phase plasma switches that are characterized by very high current emission and conduction while operating in a glow mode. The cathode properties are especially remarkable - about 2 orders of magnitude larger emission than existing thermionic cathodes. Part of the meeting was devoted to understanding these properties, and exploiting applications of this cathode. These results deserve study in order to understand the underlying physical mechanisms, and to develop ideas and insight into future applications, and foster coherent research in this area. This meeting was also motivated by the fact that there are many new applications of these devices under consideration. These include new n and electron beams for microelectronic technology, accelerators, other plasma loaded devices, plasma lenses for high energy physics, plasma accelerators, applications requiring very high cathode emission such as cathodes for pulsed accelerators and microwave sources.
