WIDE AREA RADIOACTIVE RAY DETECTOR

摘要: PURPOSE: To make high-energy region radioactive rays detect with a good sensitivity by method wherein plurality of pieces semiconductor elements are made to laminate via an insulating film in detecting part. CONSTITUTION: Radioactive 13, 14 and 15 incident on part 9. The 13 absorbed all the energies first element 10. pass through 10 without stopping. Then, second 11 15b 15c having residual also 11. Thereby, preamplifier 16, which gets sum output pulses from both 11, pulses, correspond 15, respectively detected. As 12, detection such that can not be detected only single member either is possible.
