Abstract: A method of manufacturing an electric discharge tube having an electron-emitting electrode comprising a support with a cesiumcontaining layer thereon which is activated by reaction of a gaseous compound of an inactive or inert gas and fluorine until a cesium fluoride layer having a composition (CsF, Cs) is formed. The gaseous compound, at the temperatures prevailing in the tube does not react with the surfaces of other parts.

Abstract: A METHOD FOR MAKING A NEGATIVE EFFECTIVE-ELECTRONAFFINITY SILICON ELECTRON EMITTER INCLUDES THE STEPS OF PREPARING THE SILICON BY FIRST HEATING FOR A SHORT TIME TO NEAR THE MELTING POINT OF THE SILICON, SENSITIZING BY APPLYING A LAYER OF WORK-FUNCTION-REDUCING MATERIAL, HEATING AGAIN FOR A SHORT TIME TO A LOWER TEMPERATURE THAN THE FIRST AND AGAINST SENSITIZING BY APPLYING A LAYER OF WORK-FUNCTION-REDUCING MATERIAL.

Abstract: A method of forming an array from a bundle of individual channel multipliers, the individual channels being fabricated of a lower temperature softening glass tube to permit the walls of the individual channels to be spiralled and also expanded to fill the interstices within a higher softening temperature outer tube, Also, the invention could be practiced utilizing glass tubes of the same temperature softening characteristic. The expanding and spiralling operation is preformed simultaneously by drawing the bundle of individual channels through a furnace while rotating the feed or pull assemblies of the drawing apparatus to spiral the channel bundle and exhausting the area between the individual tubes and the equal or higher temperature softening glass tube to expand the individual channels.

Abstract: The cathode for photo-electron emission 5 is comprised of an alkali metal containing layer 5d made of material for emitting photo-electrons by the entry of light or for emitting secondary electrons by the entry of electrons, such as particles which consist of an alkali antimony compound, on an Ni electrode substrate 5c on which an Al layer 5b is deposited, and has an intermediate layer 5a made of carbon nano-tubes between the alkali metal containing layer 5d and the Ni electrode substrate 5c, therefore the defect density inside the particles is decreased, and the recombining probability of electrons and holes drops remarkably, which improves the quantum efficiency.

Abstract translation: 用于光电子发射的阴极5由含有碱金属的层5d组成，所述碱金属含有层5d由用于通过入射光或用于通过电子进入发射二次电子的材料制成，例如由碱锑组成的颗粒 在沉积有Al层5b的Ni电极基板5c上，在碱金属含有层5d和Ni电极基板5c之间具有由碳纳米管构成的中间层5a，因此颗粒内的缺陷密度 电子和空穴的重组概率明显下降，提高了量子效率。
