Abstract
PURPOSE: To provide a photoelectric multiplier with high photoelectric sensitivity, by constructing a photo electric surface of alkaline antimonide through a thin film layer of potassium bromide on the conductive layer in one side of a secondary photo electric multiplier made by a lead glass thin plate.
CONSTITUTION: In a base unit material 1, made of lead glass, are provided a plurality of sloped penetration hole 2 linked to both faces 3, 4, and in a surface 5 of this base unit 1 is highly included a lead precipitated by a treatment of heating and reduction. In a portion of the faces 3, 4 except the penetration hole 2, is constructed a metal conductive layer (electrode) 6, 7 coated by nickel chrome alloy. In one face 3 is perfectly coated a metal conductive layer 6, further with a potassium bromide thin film layer 8 provided by the method of evaporation likely to enclose a side wall portion of the penetration hole 2, still further with an alkaline antimonide photo electrinc surface 9 constructed by the methods of evaporation on this thin film layer 8.
