Abstract

Electron phase trajectories for high frequency Ku-band in a diode with a nanocrystalline graphite (NCG) field emitter are compared with one with a thermo-cathode. It is shown that the field electron (FE) cathode differs from the thermo-cathode and forms short electron bunches, which can be efficiently decelerated in an output cavity. The scheme and advantages of a triode generator with a FE cathode are described. 1-D analytical evaluation of output power for the triode generator is carried out. The conclusion is drawn that maximum output power strongly depends on current density, and rises up to 80 W for 15 A/cm².
