Beam-Wave Interaction in a Gyro-Travelling Wave Tube Amplifier

Large signal analysis for a circular cylindrical smooth wall gyro-travelling wave tube amplifier has been successfully used to generate the power, and gain plots for a variety of input parameters. The gain versus frequency plots are generated for TE11 mode with the input data as the beam voltage of 100 kV, beam current of 1 Amp., waveguide cut-off frequency of 33.68 GHz and the pitch factor of 1. The gain versus frequency plots are found to be in good agreement with the published data. Additionally, the gain versus axial distance plots are generated at TE11 mode for the frequency of 9 GHz and beam current of 7 Amp. and are also found to be matching with the published data.
