Abstract
An extremely high power three-section second-harmonic 35 GHz gyro-TWT has been designed with a self-consistent nonlinear simulation code (1). An output power of 530 kW with 21% efficiency, 54 dB gain and 6% bandwidth is predicted. To substantiate the claim that a harmonic gyro-TWT can generate significantly higher output power with better stability than fundamental gyro-TWTs due to the higher beam currents allowed for the weaker harmonic interaction, a proof-of-principle Ku-band experiment is being constructed at UCLA with comparable performance predicted. A single anode 100 kV, 20 A MIG is being built to generate the alpha = upsilon /sub perpendicular to // upsilon /sub ///=1 electron beam with Delta upsilon /sub //// upsilon /sub ///=8%.<>
