Abstract: A method of manufacturing a scandate dispenser cathode having a matrix at least the top layer of which at the surface consists substantially of tungsten (W) and scandium oxide (Sc.sub.2 O.sub.3) and with emitter material in or below said matrix. If said method comprises the following steps:(a) compressing a porous plug of tungsten powder(b) heating said plug in a non-reactive atmosphere and in contact with scandium to above the melting temperature of scandium,(c) cooling the plug in a hydrogen (H.sub.2) atmosphere(d) pulverizing the plug to fragments(e) heating said fragments to approximately 800.degree. C. and firing them at this temperature for a few to a few tens of minutes in a hydrogen atmosphere and slowly cooling in said hydrogen atmosphere(f) grinding the fragments to scandium hydride-tungsten powder (ScH.sub.2 /W)(g) compressing a matrix or a top layer on a matrix of pure tungsten from said ScH.sub.2 /W powder or from a mixture of this powder with tungsten powder(h) sintering and cooling the said matrix(i) bringing emissive material into the cathode, a scandate dispenser cathode is obtained the recovery of which after ion bombardment occurs better than in cathodes having Sc.sub.2 O.sub.3 grains. The scandium is also distributed more homogeneously in the cathode than in cathodes having Sc.sub.2 O.sub.3 grains.

Abstract: An electron gun for generating an electron beam, comprising a cathode unit composed of at least a cylindrical cathode shaft having an end surface which forms an emissive surface. The cathode shaft is surrounded at least partly by a cylindrical metal heat reflection screen which extends beyond the open end of the cathode shaft. The cathode shaft and the heat reflection screen are secured in a cathode support, wherein the cathode shaft is suspended in the heat reflection screen so as to be self-supporting by means of metal strips or wires which are secured to the cathode shaft near the emissive surface and to the cathode support. This arrangement increases thermal efficiency and decreases warm-up time.

Abstract: A dispenser MK-type cathode structure adapted for storage and/or handling with subsequent activation and a method of producing the same whereby a supply source material of an emission-promoting substance is positioned in an open-ended storage chamber of a plug-like cathode insert member and sealed within the chamber by a fluid impermeable pore-free mask member. A porously sintered tungsten disc member sits above the mask member so as to have an undersurface thereof in fluid communication with the supply source material upon rupture of the mask member. The mask member is sealed to the boundaries of the storage chamber by a selfsticking organic polymer material which is thermally decomposable without residue at operational temperatures of such dispenser cathodes. The mask member comprises a unitary structure composed of a high melting metal foil having at least one surface thereof coated with the organic polymer material, a lamina of a film forming organic material having a layer of the self-thicking organic polymer material along a surface thereof or a self supporting film of the organic polymer material. The mask member is provided in a controlled thickness of sufficient dimension to resist rupture until the environment around the sealed storage chamber is subjected to cathode vacuum conditions.
