Abstract: Impregnated cathode for a vacuum tube comprising an emissive part in the form of a porous pellet 11 impregnated with a compound of alkaline earth metals; the pellet is placed in a dish 12 made of a refractory material and covered with a porous metal foil 13 forming the emissive surface of the cathode. Moreover, the pellet has a separation surface 18 between a heavily impregnated zone and a zone 10 which is not impregnated or weakly impregnated so that the said separation surface comprises at least a hollow part facing the emissive surface. By virtue of the shape of this separation surface, the lifetime of the cathode is improved.

Abstract: A method of manufacturing an emitter (8; 10) for a thermionic dispenser cathode, includes forming a porous emitter body with substantially interconnected pores, having an emission surface (11; 16) from which, upon application of heat, electrons are emitted. The porous emitter body is suitable for transporting through the substantially interconnected pores, a compound released upon application of heat, to the emission surface (11; 16), which compound, when deposited on the emission surface (11; 16), serves to lower an effective work function of the emitter (8; 10). The porous emitter body is formed by means of a process of deposition of material. At least a region of the porous emitter body is provided with a continuously varying porosity. The porosity is continuously varied by controlling at least one parameter of the deposition process.
