Large signal simulation and design of a 95 GHz harmonic gyroklystron amplifier
A three-dimensional nonlinear theory is being used to design and optimize the performance of a four cavity, 95 GHz harmonic gyroklystron amplifier. An efficiency of 19% with a gain of 37 dB was achieved for interaction between the pi mode of the vaned magnetron cavities and the fourth cyclotron harmonic of a 25 kV, 5 A axis encircling electron beam. The space charge forces in the beam and the losses in the cavity were neglected. A uniform magnetic field was assumed along the length of the device. It is expected that the magnetic field profiling will improve the efficiency to 21 to 24%.<>
