Abstract
A microwave/DC converter employing fast cyclotron wave of the electron beam. Coupling section for feeding energy into the electron beam contains two microwave cavities 3, 7. The second cavity 7 has a quadrupole electric field, receives the electron beam already slightly modulated by the first cavity 3, which is a resonant coupler with uniform transverse electric field and operates at a half of the second resonant cavity frequency. For the effective interaction in both cavities 3, 7 uniform static magnetic field corresponds to the cyclotron frequency equal to a half of external microwave power source frequency. Asymmetrically reversed magnetic field is used between microwave cavities and collector to achieve the maximal efficiency of the microwave energy conversion into DC energy. Additional electrode 9 of the collector 11 creates a potential distribution providing converter with an effective protection against secondary emission influence. Application to the design of high-power and high efficient microwave/DC power converters for operation in the centimeter and millimeter wavebands is shown.
