Abstract
An assembly is provided for improving operation of a radiation detection system which comprises a scintillation crystal 1, a photomultiplier tube 5 having a cathode maintained at a high negative voltage, a glass wall 3 positioned between the crystal and the tube, and structure 7 supporting the tube to receive a light signal from the crystal representing radiation received thereby. The assembly includes structure 4, 11 for applying the same high negative voltage to the crystal 1, and further includes structure 10 for electrically isolating the supporting structure 7 from the crystal 1 and glass wall 3, the supporting structure 7 being maintained at ground potential.
