Abstract :
Simulation results of a ka-band high power gyrotron traveling wave amplifier (gyro-TWTA) using the particle-In-cell (PIC) code are reported. The gyro-TWT amplifier with a distributed wall loss structure operates in the fundamental harmonic TE01 circular electric mode. The simulation predicts 135kw output power at ka-band with 19% efficiency, 45 dB gain.
