Abstract :
The latest results of experiments of an X-band gyro-TWA with a helically corrugated interaction region and a cusp electron beam source are presented. The cusp electron beam source uses a cold field emission emitter to produce a 37A beam accelerated with a potential of 130kV. Numerical investigations of the gyro-TWA have been completed and used to predict the saturated and small signal gain of the gyro- TWA devices. These predictions are compared with the experimental results obtained.
