GASEOUS-DISCHARGE DEVICE Russian patent published in 1998 - IPC

FIELD: plasma engineering; generation of stream of charged particles, such as ions, for various processes and for space vehicle engines. SUBSTANCE: device has axially symmetrical chamber with at least one butt-end wall, assembly for introducing high-frequency energy into chamber, and magnetic system that functions to build up stationary heterogeneous magnetic field inside chamber. Magnetic field strength coincides in radial direction to center line and in longitudinal direction to butt-end part of chamber opposite to location of high-frequency energy input assembly. The latter is made in the form of periodically repeated symmetrical zigzag-shaped conductor placed on side and butt- end walls of chamber embracing plasma-producing region. EFFECT: improved energy and gas efficiency. 5 cl, 3 dwg
