Abstract :
The latest developments and experimental results a W-band gyro-TWA with a helically corrugated waveguide and a cusp electron gun are presented. The cusp gun generated a 40 keV, 1.5 A axis-encircling electron beam. The gyro-TWA was predicted to output 5 kW with a 3 dB frequency bandwidth of 90-100 GHz.
