METHOD OF INITIATION OF EMISSION OF CHARGED PARTICLES AND CONTROL OVER IT Russian patent published in 1994 - IPC

FIELD: electronic equipment. SUBSTANCE: method of initiation of emission of charged particles and control over it involves change of electric intensity in area of cathode (emitter) and in bordering space, formation of additional electrostatic field and creation of electric charges in area located behind and aside of cathode or in it with reference to emitted particles which makes it possible to compensate partially or completely shutting-off action of spatial charge. EFFECT: expanded application field with capability to manufacture electronic power devices with high traction exceeding 1 ton. 7 dwg, 1 tbl
