Abstract: PURPOSE:To restrict and uniformalize the temperature rise of an impregnation type cathode by the cathode sleeve of tantalum and also making cathode supporter of chrome or cobalt alloys. CONSTITUTION:An impregnation type cathode 21 formed by impregnating a tungsten substrate with a melted electron emission material composed of BaO, Al2O3, and CaO is fit on the top of a cathode sleeve 22 composed of tantalum, and then welded by the resistance welding method or laser welding. A through- hole section is formed on an insulation substrate 24 composed of ceramic and a cathode supporter 23 made of 16Cr-14Ni stainless steel is fixed to the through- hole section by way of a caulking section 27. Both the cathode sleeve 22 and its supporter 23 are fixed at a welding point 26. The cathode supporter 23 can be made of Nichrome, Kovar, and 18Cr steel. As a result, the exfoliation at the welding point is reduced, thermal conductivity is improved, and cathode temperature can be made uniform.

Abstract: The invention relates to the field of production of barium-scandate dispenser cathodes or other barium-scan-date materials. A target (66) containing a mixture of BaO, CaO, Al2O3 and SC2O3 tends to be more stable, the higher the scandia (scandium oxide) content is. However, an increased scandia content results in a reduced emission capability. A destabilizing effect of BaO and CaO reactions is counteracted by the more inert SC2O3 and also AI2O3 components, as not only an increased scandia content stabilizes the material but also an increased alumina (aluminum oxide) content improves the stability.

Abstract: A electron emission cathode includes an emitter (102) having an apex (118) from which electrons are emitted. The emitter is attached to a heating filament (114) at a junction (116) and extends from the junction both forward toward the apex and rearward. A reservoir (130) of material that lowers the work function of the emitter is positioned on the rearward extending portion (128) of the emitter. By positioning the reservoir on the rearward extending portion, the reservoir can be positioned sufficiently far from the junction to reduce its temperature and thereby greatly increase the useful life of the emitter without adversely affecting the emission characteristics of the source.

Abstract: An impregnated type cathode unit and a manufacturing method therefor wherein a porous metal base and a cup member can be firmly joined together without using any interposition and the occurrence of weld defects can be eliminated to improve the reliability and yield of welding between the porous metal base and the cup member. The impregnated type cathode unit is composed of a porous metal base (11) impregnated with an electron emissive material and a cup member (12) for holding the porous metal base (11) so as to cover the bottom surface and side surface of the porous metal base (11) and expose the front surface of the porous metal base (11). A nonporous dense portion (14) is formed on the bottom surface of the porous metal base (11). The bottom portion of the cup member (12) is pressed to be deformed so as to follow the shape of the dense portion (14), thereby forming a close contact region (16). The bottom portion of the cup member (12) and the dense portion (14) of the porous metal base (11) are welded together at the close contact region (16).

Abstract: An impregnated cathode whose initial electron emitting performance, lifetime property, and insulating property for an electron gun are excellent and that is suitable for mass production, and a method for manufacturing the same. In the impregnated cathode, the porosity of the sintered body of porous metal is continuously increased as the distance in the depth direction from an electron emitting face is increased. A pellet of sintered body of metal raw material 1 has pores in it. The pores are filled with electron emitting material 2. The porosity is continuously increased as the distance in the depth direction from an electron emitting face is increased. Thus, since the discontinuity inside the pellet is not formed, a reaction generating free Ba continuously and smoothly proceeds on the entire pellet. In addition, since raw material powder having more than one kind of particle size is not necessary to be used, the manufacturing process can be simplified. Moreover, various functions such as lifetime property, etc. can be improved by making the porosity and porosity distribution in a certain range.
Abstract translation: 其电子枪的初始电子发射性能，寿命特性和绝缘性能优异且适于批量生产的浸渍阴极及其制造方法。 在浸渍的阴极中，随着电子发射面的深度方向的距离增加，多孔金属的烧结体的孔隙率不断增加。 金属原料1的烧结体的颗粒在其中具有孔。 孔被电子发射材料2填充。随着距电子发射面的深度方向的距离增加，孔隙率连续增加。 因此，由于不形成丸粒内部的不连续性，因此在整个丸粒上连续且顺利地进行产生游离Ba的反应。 此外，由于不需要使用具有一种以上种类的粒径的原料粉末，因此可以简化制造工序。 此外，通过使孔隙率和孔隙率分布在一定范围内，可以提高诸如寿命性质等各种功能。
