Abstract :
The theoretical design of a 20-GHz second-harmonic gyroklystron amplifier at a voltage near 500 kV is presented. The design of the output cavity and the nonlinear gain and efficiency are discussed. It is shown that second-harmonic operation with bunching at the fundamental frequency is feasible. With a velocity spread of 10%, numerical simulations show an output power of 15 MW (corresponding to an efficiency of 22%) at 20 GHz. The gain was about 16 dB. Output cavities that can be used to prevent feedback of the output cavity signal into the input cavity and to guarantee that the output will be in a pure mode are presented.<>
