Gyro-TWT amplifier,Beam-wave interaction,High-power microwave tubeLarge 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 ...
Gyro-TWTTWTLossyStableCompeting ModeThe start-oscillation-current of a gyro-TWT (gyrotron traveling-wave tube) determines the stable operating current level of the device. The amplifier is susceptible to oscillations when the operating current level is higher than the start-oscillation current. There ...
A scheme of dielectric-loading for a gyro-traveling wave tube (gyro-TWT) is proposed for a wider bandwidth at a higher gain. The method uses two-section dielectric-loaded cylindrical waveguide as the interaction structure, with the first section overloaded to exhibit a valley between the two pe...

The analysis of a disc-loaded circular waveguide interaction structure of a gyro-traveling-wave-tube (gyro-TWT) considering standing and propagating mode harmonics in the disc-occupied and disc-free regions, respectively, gave the beam-absent dispersion relation of the waveguide. The axial phase pro...
Two different excitation mechanisms of the frequency self-modulation (FSM) instability in a W-band dielectric-loaded gyrotron traveling-wave tube (gyro-TWT) were clearly revealed and explained. The FSM properties caused by the window reflection and collector ‘bottleneck’ versus operating beam current...
