论文摘要
在2017年秋天，在质子组件（PAB）设施的Fermilab的Tallbo液体氩（LAR）低温恒温器中安装并测试了深层中微子实验（Dune）远检测器的两个光子检测器设计。这些设计包括在印第安纳大学开发的两个灯条和一个基于科罗拉多州立大学和费米拉布（Fermilab）设计的Arapuca Light Trap的光子探测器。这些设备的性能是通过分析8周的宇宙射线数据来确定的。当前的论文仅关注Arapuca设备，因为将单独报告灯条的性能。本文简要描述了Arapuca概念，TallBO设置，并专注于数据分析和结果。
In the Fall of 2017, two photon detector designs for the Deep Underground Neutrino Experiment (DUNE) Far Detector were installed and tested in the TallBo liquid argon (LAr) cryostat at the Proton Assembly (PAB) facility, Fermilab. The designs include two light bars developed at Indiana University and a photon detector based on the ARAPUCA light trap engineered by Colorado State University and Fermilab. The performance of these devices is determined by analyzing 8 weeks of cosmic ray data. The current paper focuses solely on the ARAPUCA device as the performance of the light bars will be reported separately. The paper briefly describes the ARAPUCA concept, the TallBo setup, and focuses on data analysis and results.
