PLASMA EMITTER OF IONS Russian patent published in 1995 - IPC

FIELD: plasma generation equipment. SUBSTANCE: emitter has hollow cylindrical cathode 1 which one end has multiaperture emission window 2 and pin anode 4 is mounted with the help of bushing insulator on its other end. Solenoid 5 creating magnetic field with induction approximating 10^-3 T is installed on outer side of cathode uniaxially to it. Cathode space is filled with gas. When voltage is applied between cathode 1 and anode 4 discharge is initiated from which plasma ions are sampled through emission window. EFFECT: enhanced efficiency of emitter. 1 dwg
