Abstract

1529215 Luminescent screens COMMISSARIAT A L'ENERGIE ATOMIQUE 25 Sept 1975 [4 Oct 1974] 39391/75 Heading C4S [Also in Division H1] In a scintillator-photocathode assembly, the rear face, and optionally the front face, of the scintillator is of a multi pyramidal form. A uniform or irregular lattice of trirectangular trihedrons may be provided (also Fig. 7, and Fig. 6 respectively (not shown)). In Fig. 3 (not shown) a gas, liquid or solid low Á layer (32) is provided to form catadioptric elements. Ag and Al metallic reflecting layers are exemplified. The scintillator may be X-ray, y-ray or neutron responsive, and may be used in a photomultiplier (Fig. I, not shown). Fabrication procedures for the face are detailed.
