Abstract :
Results on the development of a two-stage, high-efficiency, high-power 8.76-GHz severed traveling wave tube amplifier are presented. Peak powers of more than 400 MW have been obtained over the complete electron beam duration, with a conversion efficiency from the electron beam to microwave energy of 45%. The maximum, single-frequency, average output power was 210 MW, corresponding to an amplifier efficiency of 24%. The severed amplifier showed an asymmetric sideband-like structure in the frequency spectrum of the microwave radiation. Theoretical analysis and simulation are used to examine the device performance. A substantial number of electrons are found to be accelerated in the slow wave structure.<>
