Abstract :
This paper presents the theoretical results of a CW W-band (88-102 GHz), 10 kW gyrotron backward-wave oscillator (gyro-BWO). A mildly relativistic, axis-encircling electron beam from a cusp gun has been designed to drive an interaction based on the cyclotron resonance maser (CRM) instability in a cavity with a helically corrugated inner surface.
