Abstract : At a given cavity mode, as the wavelength decreases, the power capability of a microwave tube amplifier also decreases because the sizes get smaller. High power gyrotron oscillators have been developed by going to very high order cavity modes. So far this has not been accomplished for amplifiers, and it is not clear whether one could in fact do this. This paper examines another approach to the problem, namely the use of a quasioptical beam (Gaussian mode) waveguide gyrotron amplifier. A closely related concept is the use of corrugated waveguide. This paper works out the linear theory of the device. Our conclusion is that it should work for an amplifier at 94 GHz having peak power of hundreds of kilowatts and average power of tens of kilowatts.
