Fundamental Cyclotron Frequency Generation from a Cusptron Oscillator.
Abstract
The first experiment is reported for microwave generation of the fundamental electron cyclotron frequency from a cusptron oscillator with a smooth conducting wall. A non relativistic axis-rotating electron beam is used to generate the TE sub 11 circular modes in a cavity by the negative mass instability. The TE sub 111 and TE sub 112 modes are separately excited without any mode competition at an approximately 1.8 kW output power with 7.8 percent efficiency. Keywords: Microwave generation; Fundamental cyclotron frequency; Cusptron oscillation.
