Analysis of Beam and Magnetic Field Parameter Sensitivity of a Disc-Loaded Wideband Gyro-TWT

The performance of a disc-loaded gyro-traveling wave tube (gyro-TWT), which is optimized a priori by controlling the structure parameters for wide device bandwidths at large gains, is analyzed for studying the sensitivity of the gain and bandwidth of the device to the beam and the magnetic field parameters. Hence, it is predicted that the optimum beam and the magnetic field parameters will result in a much wider bandwidth at a larger gain than that of a smooth-wall gyro-TWT.
