摘要
利用伴随粒子飞行时间方法，通过测量１４．７ＭｅＶ中子在聚乙烯和碳样品上的次级中子谱，得到了在０．９９—１４．７ＭｅＶ能量范围内ＳＴ－４５１液体闪烁体中子探测器的探测效率值，其总误差＜４．７％，其中统计误差＜３．５％．
Using the associated particle TOF method,the efficiency curve of ST-451 liquid scintillation neutron detector has been obtained by measuring the spectra of secondary neutrons from polyethylene and carbon induced by 14.7MeV neutrons.The neutron energy for the efficiency measurement ranges from 0.9 to 14.7MeV. The statistical error is less than 3.5% and the total error less than 4.7%.
