Paper Abstract

A novel frequency multiplying device is analyzed which provides selective gain at the cyclotron harmonics in a quasi-optical gyrotron. The device utilizes a prebunching section which enforces a double-resonance condition on the generated radiation. This selects among cyclotron harmonics in the output cavity even though the cavity structure supports all harmonics. The prebunching is accomplished by modulation of electron magnetic moments by a low frequency input rf field. A design is given for quasi-optical operation at the third cyclotron harmonic (four times the input field frequency) with 10-15% efficiency and linear suppression of the lower cyclotron harmonics.
