【摘要】 中子诱发单粒子效应会影响航空飞行器和地面辐射敏感设施用电子器件的可靠性。基于质子加速器打靶产生的中子束是研究电子器件中子单粒子效应规律和机理的重要中子源。中国原子能科学研究院100 MeV质子回旋加速器(CYCIAE-100)通过质子轰击Li靶和W靶分别产生准单能中子源和白光中子源。采用基于双液体闪烁体探测器的中子飞行时间法测量了白光中子能谱，并与理论计算谱进行对比，符合较好。同时，基于核反应理论，采用蒙特卡罗方法模拟了100 MeV质子与Li靶相互作用的次级中子，获得了准单能中子的产额、能谱和角分布。分析表明，CYCIAE-100加速器中子源参数能够满足中子单粒子效应试验的要求。更多还原

【Abstract】 The 100 MeV proton cyclotron(CYCIAE-100) at China Institute of Atomic Energy(CIAE) produces quasi-monoenergetic neutron sources and white neutron sources by bombarding Li and W targets with protons, respectively. In this paper, a test device for the single event effect of white-light neutrons and quasi-monoenergetic neutrons based on the CYCIAE-100 cyclotron of China Institute of Atomic Energy Sciences(CIAES) is developed. The white neutron energy spectrum is measured using neutron time-of-flight method based on the dual liquid scintillator detectors, and the results show good agreement with the theoretically calculated spectrum. Furthermore, based on nuclear reaction theory, the Monte Carlo method is used to simulate the secondary neutrons produced by the interaction between 100 MeV protons and the Li target, providing insights into the yield, energy spectrum, and angular distribution of the quasi-monoenergetic neutrons. Analysis of the CYCIAE-100 cyclotron neutron source parameters indicates that they meet the test requirements for single event effect induced by neutrons.更多还原
