Abstract :
Many vacuum electron devices are based on the interaction between electron beam and the electromagnetic fields. Modeling and simulation of these devices become a key element in their development. In this paper, using self-consistent nonlinear theory and PIC code, numerical simulations of a two-cavity Gyroklystron amplifier are presented. The nonlinear theory results for the Ka-band Gyroklystron Amplifier are 211kW output power at 34.95GHz, and efficiency of 22.54%, a bandwidth of 1.3%. PIC code using the same parameters, predicts peak output power of 201kW at 34.95GHz and efficiency of 21.47%. The results from nonlinear theory simulation and PIC code simulation are compared in detail and they are found to be in quite agreement in trend.
