摘要
本文采用MCNP程序计算了狭缝式裂变中子探测系统的伽玛灵敏度。并根据探测系统对14MeV中子灵敏度的实测值,得到了系统n/γ分辨参数。满足了n/γ分辨能力大于5的设计要求。
The sensitivity of a slot-collimated PIN fission chamber to gamma rays has been calculated by using MCNP-4B code. Based on the theoretical data and the measured 14 MeV neutron sensitivities, the n/γ discriminations for various configurations of the system have been obtained. The results indicate that the design of the system can meet the needs of practical measurements with n/γ discrimination of more than 5.
