论文摘要
液体闪烁体（LS）检测器中的能量非线性和分辨率相关并依赖于粒子。详细介绍了液体闪烁体检测器的统一能量响应模型。该模型采用了一种数据驱动的方法来使用单声工$γ$ -Ray来源和$^\ mathrm {12} \ Mathrm {b} $的连续$β$ speptra和连续的$β$ speptra和Michel $ e^ - 由Cosmic Muons刺激的$^\ MATHRM {12} \ MATHRM {b} $。蒙特卡洛研究表明，在没有正电子源的情况下，可以提取拟议模型的有效性和鲁棒性。这项工作将为运行和未来LS检测器的能量非线性和分辨率同时校准提供可行的方法。
Energy nonlinearity and resolution in liquid scintillator (LS) detectors are correlated and particle-dependent. A unified energy response model for liquid scintillator detectors has been presented in details. This model has advanced a data-driven approach to calibrate the particle-dependent energy response, using both the monoenergetic $γ$-ray sources and the continuous $β$ spectra of $^\mathrm{12}\mathrm{B}$ and Michel $e^-$ induced by cosmic muons. Monte Carlo studies have demonstrated the effectiveness and robustness of the proposed model, in particular, the positron energy resolution can be extracted in the absence of positron sources. This work will provide a feasible approach of simultaneous calibration of energy nonlinearity and resolution for the running and future LS detectors.
