    Abstract: An input screen and method of forming one for an image intensifier tube including a substrate in which a plurality of crystal grains of aluminum or aluminum alloy are formed in a plane with the crystal grains having non-directional shapes in the plane. The crystal grains are formed by heating in a vacuum or non-oxidizing atmosphere at a temperature between 450.degree. C. and 650.degree. C. The oxidized layer is next removed by an etchant, and a phosphor layer formed on the crystal grains by vapor-deposit.

    Abstract: A photocathode is formed by depositing a film of tellurium on a conductive base and then sensitizing the tellurium with at least two different alkali metals such as cesium and potassium or sodium and potassium. The photocathode has high sensitivity in the ultraviolet region and is substantially insensitive to solar radiation through the earth's atmosphere. Such a photocathode is useful in "solar-blind" detectors.

    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: An X-ray imaging tube which comprises a vacuum envelope, an input screen comprising a substrate located in the input end of the envelope, an input phosphor layer formed on the substrate and comprising a number of columnar phosphor crystals, and a photoelectric layer formed directly or indirectly on the input phosphor layer, an anode and an ouput screen located in the output end of the envelope, and a beam-converging electrode located in the envelope and extending along the inner surface of the envelope. The tube further comprising optically opaque layers which are formed in each columnar crystal and extending from the surface thereof. A method of manufacturing an X-ray imaging tube, disclosed herein, comprises the steps of vapor-depositing a predetermined phosphor on a substrate, thereby forming on the substrate an input phophor layer consisting of columnar crystals, vapor-depositing a predetermined material, thereby forming an optically opaque layer on the tip of each columnar crystal, sputtering the optically opaque layer, thereby removing a part of the optically opaque layer formed on the tip of the columnar crystal, vapor-depositing said predetermined phosphor, and, if necessary, repeating these steps, thereby forming a plurality of optically opaque layers in each columnar crystal, which extend from circumferential surface of the columnar crystal.
