FIELD: electricity.
SUBSTANCE: method of treatment of electronic-field cathodes includes scanning of surface of electronic-field cathode with applied electronic-field emitter, metal electrode to which supplied is positive potential relative to cathode, carbon nanotubes are used as electronic-field emitter, metal fibre is used as scanning electrode, scanning is performed upon movement of electronic-field cathode and/or electrode, at that constant or impulse potential is supplied to electrode with subsequent burning of preset structure on the surface of emitter.
EFFECT: obtaining uniform electronic-field emission from cathode surface, improving characteristics of electronic-field emission and increasing efficiency.
