Theoretical calculation, numerical simulation and experimental development of W-band gyro-devices with helically corrugated waveguides and a cusp electron gun are presented. The cusp gun generated a 40 keV, 1.5 A axis-encircling electron beam. The maximum output of the gyro-TWA was predicted to be 10 kW with a 3dB frequency bandwidth of 90-100 GHz and a saturated gain of 40 dB. The gyro-BWO output was predicted as 10 kW with a frequency tuning range of 84-104 GHz. These gyro-devices have been operated successfully and the latest experimental results will be presented.
