论文摘要
已提出了掺杂的液体氩气作为闪烁探测器中纯液体氩气的良好替代品。在这项研究中,我们报告了闪烁液量表的闪烁光的时间曲线的测量,其摩尔浓度高达1600 ppm。为这项研究开发了一种紧凑的设置,硅光电塑料(SIPM)作为光电传感器和$^{210} \ Mathrm {po} $和$^{90} \ Mathrm {srm {srm {sr {sr} $作为scintillation sources。已经开发了一个基于退出过程的有效模型来描述数据。结果表明,氙掺杂的液体氩是一个很好的快速闪烁体,可用于代替四苯基丁二烯(TPB),以保持其通过脉冲形状歧视(PSD)的粒子识别能力。
Xenon-doped liquid argon has been proposed as a good alternative to pure liquid argon in scintillation detectors. In this study, we report on the measurement of the time profile of scintillation light emitted from xenon-doped liquid argon with molar concentrations up to 1600 ppm. A compact setup has been developed for this study, with silicon photomultiplier (SiPM) as the photosensor and $^{210}\mathrm{Po}$ and $^{90}\mathrm{Sr}$ as scintillation sources. An effective model based on the de-excitation processes has been developed to describe the data. The results show that xenon-doped liquid argon is a good fast scintillator and can be used in lieu of tetraphenyl butadiene (TPB) in a way that preserves its capability for particle identification via pulse shape discrimination (PSD).
