PLASMA ACCELERATOR Russian patent published in 1997 - IPC

FIELD: plasma engineering; plasma accelerators with closed-circuit electron drift used under space conditions as electric rocket engines and as facilities solving engineering problems. SUBSTANCE: accelerator magnetic system has at least two magnetic screens closed in azimuth and placed coaxially to accelerator axis. Edges of two screens are placed in pair beyond accelerator channel on either side of its external and internal walls. Screens form spaces closed in azimuth and accommodating magnetomotive force sources. EFFECT: enlarged capabilities of changing magnetic field configuration in accelerator channel; improved efficiency and service life of plasma accelerator, reduced intensity of current fluctuations and plasma jet separation angle, reduced size and weight. 14 cl, 2 dwg
