论文摘要
我们提出了一种新的方法，用于探索液体闪烁体的内在能量分辨率（Lab + 2.5 g/L PPO + 3 mg/L BIS-MSB），以大约1 MeV电子。在巧合检测技术的帮助下，有效选择了BI 207的单能电子。通过仔细测量和分析小液体闪烁体检测器的能量分辨率，提取到976 KEV电子的内在能量分辨率为1.83％。我们使用广角康普顿重合（WACC）方法来测量液体闪烁体的发光非线性，并发现它仅对电子的内在能量分辨率造成了薄弱。如此出乎意料的大型内在能量分辨率可能来自能量传递过程中的波动。
We proposed a novel method for exploring the intrinsic energy resolution of a liquid scintillator (LAB + 2.5 g/L PPO + 3 mg/L bis-MSB) for approximately 1 MeV electrons. With the help of coincidence detection technology, single-energy electrons of Bi 207 were effectively selected. With careful measurement and analysis of the energy resolution of a small liquid scintillator detector, the intrinsic energy resolution to 976 keV electrons was extracted to be 1.83%. We used the wide-angle Compton coincidence (WACC) method to measure the luminescent nonlinearity of the liquid scintillator and found that it contributes only weakly to the intrinsic energy resolution of electrons. Such an unexpected large intrinsic energy resolution may come from fluctuations in energy transfer processes.
