Results of the numerical simulation of a klystrode with a thin-film field emission cathode array are presented. Efficiency enhancement of the amplifier or frequency multiplier owing to the application of this electron source is demonstrated.

Inspec keywords: electron field emission; cathodes; frequency multipliers; klystrons

Other keywords: frequency multiplier; efficiency enhancement; electron source; thin-film emitter; field emission cathode array; klystrode

Subjects: Microwave tubes; Electron emission, materials and cathodes
