Abstract

This invention discloses an X-ray image intensifier including a vacuum container having a metallic X-ray input window (11a), and an input plane formed on the inner surface of the X-ray input window. In the container, convergence electrodes, an anode and an output plane are sequentially disposed along the path of electrons emitted from the input plane. The X-ray input window has a hardened undulating layer (11d) on the surface thereof on the input side and the input plane has a phosphor layer (12b) formed on the hardened undulating layer, and a photoelectric surface (12d) formed on the phosphor layer.
