A W-band Gyro-BWO based on helically corrugated waveguide


A W-band gyrotron backward wave oscillator (Gyro-BWO) with a helically corrugated waveguide as the beam- wave interaction region and a cusp gun as the electron beam source is presented. The electron beam system and the beam- wave interaction were optimized for output power and frequency bandwidth by numerical simulations. A 3 dB bandwidth of -84- 104 GHz… (More)
