FIELD: electricity.
SUBSTANCE: cathode manufacturing method based on the array of field-emission emitters includes formation of cathode structure by application of a catalytic, carbon and contact layers on dielectric support structure surface containing through-holes, application of anode layer on the opposite side of the support structure with holes aligned with the cathode structure. A blank is used as a support structure and has a form of a glass plate combining a large number of microstructures with channels (MCP), inside which there are regularly spaced emitters formed by electric arc method on the surface of the catalyst layer and are based on graphitic nanoparticles effectively emitting electrons due to low electron work function.
EFFECT: enhanced reliability and improved electro-physical parameters of the device.
