発明の名称 (英語) Microwave/DC cyclotron wave converter having decreased magnetic field
発明の概要(英語)

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 group of 2n (where n=2, 3, . . . ) rod electrodes aligned symmetrically in parallel around the axis for giving the electron beam a rotational movement around the axis according to the microwave power P and 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 1/n-th of the second resonant cavity frequency (attached Figure shows the case of n=2). 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.
