Abstract :
The preliminary design results of a 1 MW, Ku-band gyrotron traveling wave amplifier (gyro-TWA) are presented. Operating at the second cyclotron harmonic of the TE11 mode, the amplifier characterizes good stability. No distributed losses or servers are required, which could potentially allow the amplifier to be operated at high average power. Large signal simulation shows that the amplifier can generate a saturated peak power of 1.06 MW with an efficiency of 26.6%, a gain of 31 dB, and a 3 dB bandwidth of about 1 GHz at 16.95 GHz when driven by a 100 kV, 40 A electron beam with 5% axial velocity spread.
