Abstract
PURPOSE:To detect neutrons in high sensitivity in a solid by a method wherein a DC voltage is applied between electrodes of noncrystalline Si or Ge to make a nucleus of Si of the like absorb the high-speed neutrons incided between the electrodes, and free electrons and a hole couple produced are taken out. CONSTITUTION:A hydro-high resistance layer 8 is arranged on one surface of the first conductive type layer 7, and on the other surface thereof is cover-attached the electrode 5. Additionally, the second conductive type layer 9 is arranged on the layer 8 and the electrode 6 is fitted on the other surface of the layer 9. To operate the detector, the electrodes 5 and 6 are applied with the DC voltage which is turned to a backward bias to cause the measured neutrons to be incided from the top, the bottom or the side. Whereby a large absorption cross-section of the necleus of Si etc. causes the high-speed neutrons to be absorbed in the nucleus and the nucleus excited radiates gamma-ryas to reach the grounded state. Further, the gamma-rays produce numerous free electrons and positive hold couples in the layer 8 which are led out and detected as current pulses generated between the electrode 5 and 6, thereby enabling the neutrons to be detected in high sensitivity in the solid.
