论文摘要
水基液体闪光灯（WBL）为大型检测器提供了一个有吸引力的目标介质，能够增强切伦科夫和闪烁信号与单个目标的分离。这项工作表征了基于实验室/PPO液体闪烁体（LS）的WBLS样品的闪烁特性。 X射线发光光谱，衰减曲线和相对光的产量是针对不同LS浓度的WBL以及纯LS的pPO浓度范围的pPO浓度，最高为90 g/l。 WBL的闪烁特性与PRECURSOR LAB/PPO相关：从实验室中的90 g/L PPO开始，在合成之前，所得的WBL具有光谱属性，相反，实验室中的10 g/L PPO匹配。这可能表明WBLS样品中有源PPO的浓度取决于它们的处理。
Water-based liquid scintillators (WbLS) present an attractive target medium for large-scale detectors with the ability to enhance the separation of Cherenkov and scintillation signals from a single target. This work characterizes the scintillation properties of WbLS samples based on LAB/PPO liquid scintillator (LS). X-ray luminescence spectra, decay profiles, and relative light yields are measured for WbLS of varying LS concentration as well as for pure LS with a range of PPO concentrations up to 90 g/L. The scintillation properties of the WbLS are related to the precursor LAB/PPO: starting from 90 g/L PPO in LAB before synthesis, the resulting WbLS have spectroscopic properties that instead match 10 g/L PPO in LAB. This could indicate that the concentration of active PPO in the WbLS samples depends on their processing.
