CATHODE OF PLASMA ACCELERATOR (VERSIONS) Russian patent published in 2014 - IPC H05H1/54 F03H1/00 

FIELD: engines and pumps.

SUBSTANCE: in compliance with first version, this cathode comprises electron emitting hollow elements, pipeline with channels to feed working body to said elements, common heat duct around every hollow element composed by the body of revolution. Heat duct material features heat conductivity factor not lower than that of the material of said hollow elements. Every said element is connected to separate channel of said pipeline while throttle is arranged in every channel of working body feed side. Note also that throttle orifice cross-sections are identical. In compliance with second version, said common heat duct entwines every said hollow element over its outer side and over its outlet end. Common heat duct outlet end is provided with holes, their axes being aligned with those of hollow electron emitting elements. Note also that flow sections of said holes in said common heat duct is not smaller than that in holes of said emitting electron hollow elements.

EFFECT: longer life, higher reliability, uniform distribution of working body over said elements.
