论文摘要
从液体氩气中检测闪烁光是许多当前和未来的核/粒子物理实验的实验技术，例如中微子物理学，中微子物理学，中微子双β型和暗物质搜索。尽管添加少量的氙气（掺杂）以增强光产量的想法引起了极大的兴趣，但这种技术从未以必要的规模或精度证明。在这里，我们报告了100 L低温血管中的氙气掺杂。 XENON掺杂以四个浓度为1.00 $ \ pm $ 0.06 ppm，2.0 $ \ pm $ 0.1 ppm，5.0 $ \ pm $ 0.3 ppm和10.0 $ \ pm $ 0.5 $ 0.5 ppm。这些测量值代表了发布最精确的氙气掺杂测量。我们观察到平均光收益率在1.92 $ \ pm $ 0.12（SYST）$ \ pm $ 0.02（stat）的倍数为10 ppm时。
The detection of scintillation light from liquid argon is an experimental technique key to a number of current and future nuclear/particle physics experiments, such as neutrino physics, neutrinoless double beta decay and dark matter searches. Although the idea of adding small quantities of xenon (doping) to enhance the light yield has attracted considerable interest, this technique has never been demonstrated at the necessary scale or precision. Here we report on xenon doping in a 100 l cryogenic vessel. Xenon doping was performed in four concentrations of 1.00$\pm$0.06 ppm, 2.0$\pm$0.1 ppm, 5.0$\pm$0.3 ppm, and 10.0$\pm$0.5 ppm. These measurements represent the most precise xenon doping measurements as of publishing. We observed an increase in average light yield by a factor of 1.92$\pm$0.12(syst)$\pm$0.02(stat) at a dopant concentration of 10 ppm.
