PLASMA ION EMITTER Russian patent published in 1999 - IPC

FIELD: generation of plasma and intensive ion beams with large cross-section. SUBSTANCE: Plasma ion emitter has hollow cylindrical cathode with multiaperture emission window in one of its butts and bar anode placed uniaxially to cathode. Solenoid having even number of sections is mounted on external side of cathode uniaxially to it. Windings of adjacent sections are connected in opposition. Solenoid creates inhomogeneous magnetic field in space of cathode which induction is maximal close to cathode and does not exceed 10^-3 T along axis of discharge system. EFFECT: increased gas efficiency and stability of parameters of plasma emitter with maintenance of density of current of plasma emission and homogeneity of its distribution over surface of emitter. 1 dwg
