小角中子散射(SANS)测量被样品散射的中子的角分布,以计算散射过程中的动量转移。然而,入射中子在被记录之前可能首先与探测器的结构材料发生不必要的碰撞。这种假中子的检测可能会导致对受检样品微观结构的有偏见的解释。本文介绍了一种新型的硼衬蜂窝式气体中子探测器。模拟和实验结果表明,该方法可使虚中子抑制能力提高3 ~ 10倍。
Small Angle Neutron Scattering (SANS) measures the angular distribution of neutrons scattered by the sample to calculate the momentum transfer in the scattering process. However, the incident neutrons may firstly undergo unwanted collisions with the detector’s structural material before they are registered. The detection of such spurious neutrons might lead to a biased interpretation to the microstructure of the inspected sample. A newly-designed boron-lined honeycomb converter based gaseous neutron detector is introduced in this study to provide a capability for suppressing the spurious neutrons. The simulation and experimental results indicate that a 3 to 10 times improvement for the spurious neutron suppression capability could be achieved.
