FIELD: electricity.
SUBSTANCE: generator of wide-aperture flow of gas-discharge plasma includes hollow cathode with base, which is installed coaxially into hollow insulation and covered with cover plate so that height of cavity of hollow cathode is determined with the ratio of 3λ<L<5λ, where λ - length of free passage of electron in flow of gas-discharge plasma. Bases of anode and cathode are perforated, thickness of insulation between hollow anode and hollow cathode is determined by the ratio of 0.5d<h<d, where d - diameter of coaxially located holes in bases of anode and cathode.
EFFECT: increasing uniformity of particles distribution across the flow cross section and simplifying the design.
