Abstract: A quick-heating planar cathode employs a disk of fine mesh wire of refractory metal around which is bonded or sintered a porous layer of tungsten particles impregnated with electron-emissive material, a layer of inorganic insulation covering one surface of the porous cathode, and a heater on the insulating surface.

Abstract: A unitary heater, cathode, and control electrode structure for an electron discharge device is formed by coating a disk of a porous refractory metal with an inorganic insulating layer, overcoating the insulating layer with a film of refractory metal, forming a grid pattern in the film on one side of the disk, forming openings in the film and insulating layer corresponding to the pattern, and impregnating the disk with thermionic emissive material.
