在快中子实验中,无论研究带电粒子引起的核反应所产生的中子,或是研究快中子与原子核进行弹性和非弹性散射相互作用产生的中子,常常涉及角分布测量。在这些测量中,中子探测器如果采用庞大笨重的屏蔽(重量常以吨计),工作很不方便。为了提高实验工作的效率以及保证测量数据的质量,建造灵活方便的角分布仪装置是十分必要的。
In fast neutron experiments, the study of the neutron generated by the nuclear reaction caused by the charged particles or the study of the neutron produced by the interaction between the fast and the elastic nuclei by the elastic and inelastic scattering often involves the measurement of angular distribution. In these measurements, neutron detectors using huge bulky shielding (weight often in tons), work very inconvenient. In order to improve the efficiency of experimental work and ensure the quality of measurement data, it is necessary to construct a flexible angle distributor device.
