Abstract :
Presented in this paper are the results of a 10 kW W-Band Gyro-BWO based on a helically corrugated interaction region and novel cusp electron gun. Microwave measurements of the helically corrugated interaction region are shown to give a low loss of 1dB over the frequency region of interest (84-104 GHz). The measured dispersion was found in good agreement with the analytically calculated and numerically simulated dispersions. The design and simulation results of the cusp electron gun of the Gyro-BWO device are given in this paper.
