论文摘要
了解液体氙气闪烁和电离过程是改善当前和未来检测器中的分析方法的极大兴趣。在本文中，我们调查了$ \ MATHCAL {O} $（10 keV）电子的激发过程的动态，来自$^{83M} $ kr源和$ \ Mathcal {o} $（6 mev）$α$ - 粒子，来自$^{222} $ rn cource，两者都与XENON混合。单个光子采样方法用于记录光子到达时间，以便获得大约0.8 v/cm至1.2 kV/cm之间不同应用的电场的相应时间分布。讨论了结果中观察到的信号的能量和场依赖性。
Understanding liquid xenon scintillation and ionization processes is of great interest to improve analysis methods in current and future detectors. In this paper, we investigate the dynamics of the scintillation process for excitation by $\mathcal{O}$(10 keV) electrons from a $^{83m}$Kr source and $\mathcal{O}$(6 MeV) $α$-particles from a $^{222}$Rn source, both mixed with the xenon target. The single photon sampling method is used to record photon arrival times in order to obtain the corresponding time distributions for different applied electric fields between about 0.8 V/cm to 1.2 kV/cm. Energy and field dependences of the signals which are observed in the results are discussed.
