【摘要】 要对丰中子核进行动力学全测量研究其能级结构和探究多个价中子之间的相互作用行为,具有多中子分辨本领的中子谱仪就成为必不可少的探测工具。由于探测效率低、串扰影响等技术难题的存在,多中子关联谱仪的研制已经成为丰中子核研究的竞争热点。通过对现有的该类中子谱仪优缺点了进行分析对比,提出了针对不同能量的中子探测分能段对待的方案。结合多中子甄别技术的发展,阐述了多中子探测技术的关键问题和可行的解决方案。更多还原

【Abstract】 To investigate the weakly bounded states of the neutron-rich nuclei and study the correlation between the valence neutrons by performing complete kinetic measurement,multi-neutron correlation spectrometers are badly needed as key experimental instruments.Because of the problems of low detection efficiency and cross-talk etc.,the development of such kind of neutron spectrometer became a focus in the field of neutron-rich nucleus research.By the comparison of the existing neutron spectrometers,the idea to deal with the neutron detection with different design for different energy range was mentioned.With the consideration of the new technique of multi-neutron discrimination,the key difficulty and the feasible solution were pointed out.更多还原
