Design and use of controlled porosity reservoir cathodes

Design and use of controlled porosity reservoir cathodes

Sintered tungsten wire, reservoir cathodes offer high current density operation with very long life time and extremely uniform emission current. The cathodes, however, should be designed for the specific performance requirements of the device. This presentation provides information on performance ca...

Zusammenfassung:Sintered tungsten wire, reservoir cathodes offer high current density operation with very long life time and extremely uniform emission current. The cathodes, however, should be designed for the specific performance requirements of the device. This presentation provides information on performance capabilities and describes the design process.
