Abstract

The cold dispersion relation of a vane-loaded cylindrical waveguide was combined with the hot dispersion relation of a gyro-TWT in an unloaded waveguide to obtain the hot dispersion relation of a vane-loaded gyro-TWT. Both the device gain and bandwidth were increased by controlling the beam parameters, namely, the voltage, current, and velocity pitch factor of the beam, as well as its location. The device gain and bandwidth characteristics were also found to be highly sensitive to the background magnetic field. Study clearly demonstrated the need to take into account the role of the beam and background magnetic field parameters in efforts to broadband a gyro-TWT by using innovative structures like a vane-loaded cylindrical wave.
