An experimental detection system based on tagged neutron method was developed for detecting the explosives embedded in a concrete wall. The simulant samples of TNT and ammonium nitrate were tested by this system under different conditions. The experimental results were compared with the MCNPX code simulation results and have good consistency. On this basis, the simulation of RDX and Tetryl explosives hidden in different thickness walls was carried out. The simulation results show that the experimental system can detect the 300 g explosive hidden in a wall with a thickness of no more than 10 cm by using the ratio of delta and its standard deviation.

用于墙壁爆炸检测的标记中子系统的 MCNPX 模拟和实验测试

开发了一种基于标记中子法的实验检测系统,用于检测混凝土墙内埋置的爆炸物。该系统在不同条件下对TNT和硝酸铵的模拟样品进行了测试。实验结果与MCNPX代码仿真结果进行了对比,具有良好的一致性。在此基础上,对隐藏在不同厚度壁中的RDX和Tetryl炸药进行了模拟。仿真结果表明,实验系统利用delta与其标准差的比值,可以检测出隐藏在厚度不超过10cm的墙壁中的300g炸药。
