Abstract:
Sensitivity of combination PIN detector was studied.The neutron sensitivity of the detector was measured and simulated by Monte-Carlo method.The detector's gamma sensitivity was measured and compared to usual PIN detector.The experiment and calculation study indicate that the neutron sensitivity of combination PIN detector can be adjusted by selecting polyethylene converter,and the detector is insensitive to gammarays.The combination PIN detector can be used to detect pulse neutron in neutron and gamma mixture radiation field.
