Title:
PHOTOELECTRIC FACE, AS WELL AS PHOTOMULTIPLIER TUBE EQUIPPED WITH IT, X-RAY GENERATOR, ULTRAVIOLET RAY IMAGE TUBE, AND X-RAY IMAGE INTENSIFIER
Document Type and Number:
Japanese Patent JP2007026785
Kind Code:
A
Abstract:

To provide a photoelectric face having high characteristics, a photoelectron multiplier provided with it, an X-ray generator, an ultraviolet ray image tube, and an X-ray image intensifier.

This photo electric face is that in which a mixed crystal layer of magnesium oxide and zinc oxide expressed by a composition formula MgxZn(1-x)O (0<x<1) is film formed on a substrate, and emit photoelectrons into vacuum. By this photoelectric face, (1) the photoelectric face of a large area is enabled, (2) a curved substrate and the photoelectric face on a curved face on a plano-convex face is fabricable, (3) it is fabricable at a low cost, and high characteristics are obtained. Moreover, compatibility is high since the photoelectrons are emitted into the vacuum, and a high photoelectric effect can be obtained since outer photoelectric effect is utilized.
