Abstract
1377783 Photo-electric detector system G D SEARLE & CO 1 Feb 1972 [1 Feb 1971] 4657/72 Heading G1A [Also in Divisions G2 and H4] A radiation detector uses a light guide 45 between a scintillating crystal 37 and the lightsensitive surfaces 26 of a plurality of photomultipliers, e.g. P8-P12, the surfaces of the light guide 45 which are not transmitting light to the photo-multipliers surfaces 26 via an optical coupling compound or receiving light from the scintillating crystal 37 via an optical coupling compound being made light absorbent as at 17. This is said to reduce “hot spots”. Triangular cross-section indentations 15 in the surface of the light guide are provided between adjacent photo-multipliers. The outputs from the photomultipliers are matrixed to produce x, y and z signals, the signals being fed to an oscilloscope only when the z signal indicates radiation within a selected energy window. The oscilloscope output may be photographed, or the signals may alternatively be fed to a digital computer.
