Abstract:

Microwave radiation at high harmonics of the electron cyclotron frequency is generated from a cusptron device. An axis-rotating beam of 30kV, 3.5 A, 4 us, and 60 pps interacts with modes in a six-vane circuit by the negative mass instability. Radiation power is more than 10 kW with approximately 10 percent electronic efficiency at 6.0 GHz, which corresponds to the sixth harmonic of the electron cyclotron frequency. With the same circuit and a 28 kV, 1.5 A beam, we also obtained approximately 4.0 kW radiation with 9.5 percent efficiency at the fourth harmonic frequency of 3.9 GHz. Keywords include Microwave generation, Cusptron oscillator, and Six-vane circuit.
