Most gyrotron traveling wave tubes (gyro-TWT) currently employ temperature-limited magnetron-injection electron guns to produce electron beams with high perpendicular to parallel velocity ratios. Certain problems with these guns have inspired the investigation of alternative space-charge-limited guns. An ...
The mode competition problems in a gyro-TWT were investigated by a nonlinear steady-state multimode theory. Simulation results show the effect of backward wave oscillation mode (TE21(2)) and working mode (TE11(1)) on each other for different beam current and guiding center radius, which help...
The corrected dispersion relation governing the linear interaction of a TE mode in a circular cylindrical wave guide with an annular beam of gyrating electrons in a gyro-TWT configuration is derived. The derivation of the correct dispersion relation no longer involves any integration with respect to...

A high power gyro‐TWT operating in the low‐loss TE01mode has been constructed at UCD that is driven by a 100 kV, 5 A, v⊥/vz=1.0 MIG electron beam with Δvz/vz=5%. The amplifier is predicted by a large‐signal simulation code to generate 140 kW at 94 GHz with 28% efficiency...
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...
A second-harmonic TE/sub 21/ gyro-TWT is being fabricated at UCD that is predicted to produce 50 kW in Ka-band with 20% efficiency, 30 dB saturated gain and 3% bandwidth. The device is driven by a 70 kV, 3.5 A large-orbit axis-encircling electron beam from a Northrop Grumman cusp ...
