Calibration Technique of Neutron Sensitivity for γray Detector

Institute of Nuclear Physics and Chemistry, China Academy of Engineering Physics, Mianyang 621900, Sichuan, China

摘要: 叙述了γ探测器的14.1 MeV中子灵敏度标定原理和屏蔽方法，利用MCNP程序建模，优化设计了对γ和中子高屏蔽性能的屏蔽体。实验研究表明，其信噪比最高达10∶1，比测量点本身的信噪比1.35∶1提高了7倍，从而实现了γ探测器的中子灵敏度标定。 It is introduced that a method and principle for calibrating 14.1 MeV neutron sensitivity of γray detector. A shield system for scattering neutrons and γrays has been optimized by MCNP code. The experimental results show that the signaltonoise ratio of the system is about 10:1， 7 times higher than the value of 1.35〖KG-*4〗∶〖KG-*4〗1 without shield system. Calibration of neutron sensitivity of γray detector is then accomplished.
