Abstract
PURPOSE:To discriminate many scintillators by a reduced number of photomultiplier tubes and to lower manufacturing cost, by arranging a plurality of light guides in a row direction and inclining each of the boundary lines thereof in one row and making inclination directions opposite at every row. CONSTITUTION:Thin plate-shaped scintillators 1 are arranged in line and row directions to form a plate-shaped block. For example, when the emission of light is generated in the scintillator 1 of the third row, outputs are simultaneously generated from the photomultiplier tube 3 connected by the light guide covering the second and third rows and the photomultiplier tube 3 connected by the light guide covering the third and fourth rows and it can be discriminated that the emission of light is generated in the third row. The boundary line of the input surface of each of the light guides 2 is inclined in one row and, since the inclination directions thereof are opposite at every row, an output ratio is different and the line of the scintillators 1 can be discriminated from said ratio. By this method, many scintillators can be discriminated by a reduced number of the photomultipliers and manufacturing cost is lowered and spatial resolving power is enhanced.
