Abstract

The design of a 95 GHz, 70 kV, 5 A, (alpha) equals 1.5, (Delta) (upsilon) _z/(upsilon) _z equals 7%, six-vane, (pi) mode, third-harmonic gyro-TWT is presented which is predicted by a nonlinear self-consistent simulation code to yield a peak output power of 90 kW and 26% efficiency, a saturated gain of 61 dB and 3% constant-drive bandwidth. The stability of the device is examined using linear theory and a multimode time dependent PIC code. In addition, the wideband input coupler and output mode converter are also described.
