W-Band Amplifier Klystron with a Sheet Beam

Аннотация

A W-band amplifier klystron has been designed based on a sheet electron beam and multigap cavities formed from a two-side comb slow-wave system segment. It has been shown via computer simulation that the proposed device has an output power higher than 1 kW, a gain of about 50 dB, an amplified frequency band of 0.4 GHz, and an efficiency of more than 10% at an essentially lower accelerating voltage compared with foreign analogous.
