Abstract :
Technological and design parts of plasma spraying metal-porous cathodes manufacturing for high-power multi-beam klystron are presented. The samples of cathode assemblies and their parameters are shown when operating in real devices. The results of investigations of the cathodes emission properties in the forced temperature conditions are presented in order to determine the maximum current density and predict emission durability.
