中子检测爆炸物技术主要有热中子法(TNA)、快中子法(FNA)、脉冲快热中子法(PFTNA)、快中子伴随α粒子成像技术(API-TOF)。其中,基于快中子的伴随α粒子检测技术可以有效降低在检测过程中14MeV中子与被检测物品周围环境中产生的强γ辐射本底,进而提高检测效率。为实现利用伴随α粒子技术检测爆炸物,进行了如下实验。采用带有α阵列探测器的中子发生
Neutron detection of explosives technology are thermal neutron method (TNA), fast neutron method (FNA), fast pulse thermal neutron method (PFTNA), fast neutron with alpha particle imaging technology (API-TOF). Among them, the fast neutron-based concomitant α particle detection technology can effectively reduce the strong gamma radiation background generated by the surrounding environment of 14 MeV neutron and the detected object in the detection process, thereby improving the detection efficiency. In order to achieve the detection of explosives with the use of the alpha particle technique, the following experiment was conducted. Neutron takes place with an alpha array detector
