| 摘 要： | 在中子检测爆炸物的研究中，利用14 MeV中子与原子序数大于5的原子核相互作用可产生特征射线的特性，采用伴随粒子法结合D-T中子飞行时间技术，使用尺寸为12.5 cm20 cm的大体积NaI(Tl)探测器，对爆炸物所含元素C，N，O以及一些模拟炸药样品进行了瞬发谱测量。获得了几种典型样品的特征谱，并对其进行了分析。实验结果与欧盟同期结果进行了比较，表明本实验研究达到了目前国际同类实验的水平，可以为中子检测爆炸物识别技术提供实验支持。

| Abstract: | In research of explosive detection by neutron probe, the gamma rays was produced by 14 MeV neutron bombardment on the sample nucleus with atom numbers bigger than 5. The gamma spectra of typical elements, such as C, N, O and simulated explosive, were measured by associated particle technique (APT) and time of flight (TOF). The large NaI(Tl) detector with the dimension of 12.5 cm20 cm was used. The measured gamma spectra were compared with those of European Union (EU). The results show that both of the experiments were at the same level. |
