Abstract
A gyrotron traveling wave amplifier (gyro-TWA) with a cusp electron gun and a helically corrugated waveguide operating in the W-band is presented. When driven by an electron beam of energy 40 keV and current 1.5 A, the simulated microwave output power is 5 kW (CW) with a 3 dB frequency bandwidth of 90-100 GHz and a saturated gain of 37 dB. Linear analyses, numerical simulation and the latest experimental results will be presented.
