论文摘要
在表面实验室运行的中型单相液体氩原型检测器旨在测量液体氩（LAR）发出的闪烁光。该检测器采用42个8英寸的光电倍增管（PMT）来收集光。通过分析信号的波形，可以获得表征液体氩纯度的慢衰减时间常数，例如可以获得重要的检测器特性。为了描述信号波形，使用了基于液体氩光发射的原理（包括光的快速和慢速组件），该模型考虑了TPB重新排放过程和信号反射效应。使用三指数的时间结构引入TPB重新排放过程。此外，实验结果为峰后驼峰结构提供了全面的验证，这归因于信号反射。
The midsize single-phase liquid argon prototype detector, operating at the surface laboratory, is designed to measure scintillation light emitted by the liquid argon (LAr). The detector employs 42 8-inch photomultiplier tubes (PMT) to collect the light. By analyzing the waveform of the signal, important detector characteristics such as the slow decay time constant that characterizes the purity of the liquid argon can be obtained. To describe the signal waveform, a model that considers the TPB re-emission process and the signal reflection effects based on the principles of liquid argon light emission, including fast and slow components of light decay, is used. The TPB re-emission process is introduced using a three-exponential time structure. Additionally, experimental results provide comprehensive validation for a post-peak hump structure, which is attributed to signal reflection.
