ГАЗОРАЗРЯДНЫЙ ПЛАЗМЕННЫЙ КАТОД

摘要

FIELD: plasma generation. ^ SUBSTANCE: electrode set of plasma cathode has hollow cylindrical cathode with slit-shaped output aperture and hollow anode. Height of the latter depends on distance between cathode aperture and control grid. Ratio of anode height and control grid transverse incision is greater than unity. Cathode aperture width depends on thickness of spatial charge cathode layer. ^ EFFECT: enlarged surface area of plasma uniformly emitting electrons. ^ 1 cl, 1 dwg
