  • 摘要: 利用标准放射伽玛源(22Na,137Cs)测量了尺寸为Φ5.08 cm×2.54 cm的BC501A中子探测器的脉冲幅度谱,并利用MCNP软件进行了模拟,详细考虑了探测器的几何尺寸、材料、以及能量分辨函数,计算结果很好地再现了实验数据,精确地确定了康普顿边缘的位置,完成了BC501A中子探测器的能量刻度。并采用14.8 MeV的T(d,n)4He中子源对聚乙烯样品开展了中子学积分实验,结果表明,BC501 A中子探测器的能量刻度过程以及聚乙烯中子学积分实验数据的处理过程是完全合理并且可靠的。


    The pulse-height spectra of the BC501A scintillator (Φ5.08 cm×2.54 cm) were measured using 22Na, 137Cs γ-ray source, in which MCNP simulation was applied. The simulated pulse-height spectra show a good agreement with the measured data considering the geometry, material and energy resolution function of the scintillator. The position of the Compton edge has been precisely determined and an accurate energy calibration of BC501A scintillator was also achieved. An neutronics integral experiment of polythene with 14.8 MeV T(d, n)4He neutron source was carried out. The results indicate that the procedures of the energy calibration experiment of BC501A scintillator and the data analyzing in the polythene integral experiment are reasonable and reliable.
