Radiation fluorescent photomultiplier tube which is produced by the method and method of manufacturing a radiation fluorescent photomultiplier tube

摘要

The invention relates to a method of manufacture of a radiological image intensifier. / p & & p & in the intensifier, it covers the gate g, which is closest to the anode a of a layer of a material, of the conductor, and having the what of oxidizing the alkali metals. This avoids the parasitic lighting of the observation screen 4 of the alkali metals deposited unintentionally on this gate g during the production of the photocathode 3.
