在本文介绍的积分基准实验中，用氘氚（DT）聚变中子辐照了300 mm× 300 mm× 100 mm的铝（Al）平板样品。用BC 501 A有机液体闪烁体探测样品中泄漏的中子，通过飞行时间（TOF）方法，考虑探测器效率，由TOF曲线得到中子能谱。为了比较，一些泄漏中子谱也通过结合蒙特卡罗中子输运代码与ENDF/B-VIII的评估核数据进行了模拟。0、JENDL-4.0和CENDL-3.1库。除个别能量范围外，所有计算值与实验值的符合率均在10%以内。使用ENDF/B-VIII预测的值。在120 ℃时，CENDL-3.1和JEDNL-4.0库的数据在9.5-12 MeV范围内的差异较大。本文还讨论了造成这些差异的可能原因。
In the integral benchmark experiment presented here, an aluminium (Al) slab sample (300 mm× 300 mm× 100 mm) was irradiated with Deuterium-Tritium (DT) fusion neutrons. The neutrons leaking from the sample were detected by a BC501A organic liquid scintillator through the time-of-flight (TOF) method; the neutron energy spectra were derived from the as-obtained TOF curves by considering the detector efficiency. For comparison, some leakage neutron spectra were also simulated by combining a Monte Carlo neutron transport code with evaluated nuclear data from the ENDF/B-VIII. 0, JENDL-4.0 and CENDL-3.1 libraries. All the calculated values agreed with the experimental data within 10%, except for a few energy ranges. The values predicted using the ENDF/B-VIII. 0 library were lower and higher than the measured ones at below and higher above 4 MeV, respectively; the data based on the CENDL-3.1 and JEDNL-4.0 libraries exhibited some larger differences in the 9.5–12 MeV range at 120∘. The possible causes of these discrepancies are also discussed.
