IPC: G01T1/20
Filed: 1989-05-02
Abstract: PURPOSE:To obtain clear fault images and enhance productivity and reliability of a detector by sticking a tape to a massive scintillator polished and molded into a rectangular parallelopiped, and channeling the scintillator to predetermined depth at predetermined pitchs, and then pushing a reflector into the channeled portion and fixing the reflector thereto. CONSTITUTION:Aluminium foil 9 or conductive tape is stuck to a massive scintillator 1a polished and molded into a rectangular parallelopiped, and, after the scintillator is channeled to predetermined depth at predetermined pitchs, a reflector 2 is pushed into the grooved portion and fixed. Irregularity between the scintillator 1 and the reflector 2 is thereby removed and a uniform face is formed.
