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 aluminium or aluminium alloy are formed in a random manner in a surface. The crystal grains are formed by heating in a vacuum or non-oxidising atmosphere at a temperature between 450°C and 650°C. The oxidised layer is next removed by etchant and a phosphor layer formed on the crystal grains by vapour-deposition.

Abstract: An alkali metal generating agent (1) for use in forming a photoelectric surface emitting a photoelectron corresponding to an incident light or a secondary electron emission surface emitting a secondary electron corresponding to an incident electron, which comprises an oxidizing agent comprising at least one tungstate having an alkali metal ion as a counter cation and a reducing agent for reducing the above cation. The above metal generating agent (1), which includes a tungstate having weaker oxidizing power than that of a chromate, undergoes slower oxidation-reduction reaction, which results in easier reaction rate control as compared to a conventional technique using a chromate, leading to the generation of an alkali metal with good stability.

Abstract: A photomultiplier is constituted by a photocathode and an electron multiplier having a typical structure in which a dynode unit having a plurality of dynode plates stacked in an incident direction of photoelectrons, an anode plate, and an inverting dynode plate are sequentially stacked. Through holes (101) for injecting a metal vapor are formed in the inverting dynode plate (13) to form secondary electron emitting layers on the surfaces of dynodes supported by the dynode plates, and the photocathode. With this structure, the secondary electron emitting layers are uniformly formed on the surfaces of the dynodes. Therefore, variations in output signals obtained from anodes can be reduced regardless of the positions of the photocathode.
