Abstract
The paper introduce a particle simulation of a Q-band gyro-TWT operating in the circular waveguide TE01 mode at the fundamental cyclotron harmonic. The simulation predict that it can produce an output peak power over 265 kW at 46.5GHz, corresponding to a 37.8% efficiency, 47.2 dB gain, the 3dB bandwidth is about 3.5GHz. The potential backward wave oscillations (BWOs) TE11 TE21 and TE02 spurious modes are effectively suppressed by the distributed lossy loaded waveguide.
