High current density, reservoir cathodes for high frequency applications

High current density, reservoir cathodes for high frequency applications

Sintered tungsten wire, reservoir cathodes offer high current density operation with very long life time. The diffusion rate can be selected consistent with the current emission density. This presentation will describe the impact of this technology and present the latest test results.
