IMPROVEMENTS IN OR RELATING TO SCINTILLATION COUNTERS

Patent ·
OSTI ID:4122283
The energy resolution of a scintillation counter may be improved by making the Nal(Tl) crystal spherical or spheroidal in form, roughening its surface, and surrounding it with a white reflecting powder (e.g., aluminum oxide or magnesium oxide) except at the part which is coupled to a photomultiplier. In this way, the light reaching the photomultiplier cathode is rendered less dependent on the scintillation position in the crystal. (D.L.C.)
