PLASMA ACCELERATOR Russian patent published in 1994 - IPC

FIELD: gas-discharge generators. SUBSTANCE: plasma accelerator has path for advancing working body into gas-discharge chamber of amplifier and gas-discharge chamber of amplifier and gas-discharge chamber of gas-discharge plasma cathode. Cavity of gas-discharge chamber of amplifier and cavity of gas-discharge chamber of gas-discharge plasma cathode are communicated with cavity of advancing path through oxygen pumping-out chamber. The latter is formed by a part of gas trunk, disposed at the input of corresponding gass-discharge chamber and made of solid oxidizing electrolyte. Oxygen-permeable electrodes are mounted onto opposite surfaces of solid oxidizing electrolyte from the side of cavity of advancing path and from its inner side. Cavity of working body advancing path communicates with the cavity of additional chamber through part of the trunk, made of solid oxidizing electrolyte. Cavity of additional chamber may communicate with environment through at least single channel. Positive pole of power supply is connected to electrodes, disposed on the sides of the cavities of additional chambers. Negative pole of the supply is connected to electrodes, disposed from the side of working body advance path cavity. The bushing may bed mounted coaxially inside cavity of oxygen pumping-out chamber. The bushing forms annular space with electrode, disposed from the side of the cavity of working body advancing path. EFFECT: improved reliability; increased service life of the amplifier; improved purity of plasma. 6 cl, 3 dwg
