论文摘要
液体氩时间投影室计划在美国高能物理中微子计划的未来中扮演核心角色。特别是，该检测器技术将构成40 Kton深地下中微子实验（Dune）的基础。在本文中，我们将Dune实验提出的双相远面检测器设计作为起点，并询问必须进行哪些更改，以使四个10 KT模块之一对重型弱相互作用的大型粒子（WIMP）暗物质敏感。我们表明，通过控制背景和使用低放射性氩气的使用，在该时间表上可以在该时间范围内商购，并且光检测的显着增加，一个沙丘样模块具有竞争性的WIMP检测灵敏度，尤其是高于100 GEV的暗物质质量。
Liquid Argon Time Projection Chambers are planned to comprise a central role in the future of the U.S. High Energy Physics neutrino program. In particular, this detector technology will form the basis for the 40 kton Deep Underground Neutrino Experiment (DUNE). In this paper we take as a starting point the dual phase far detector design proposed by the DUNE experiment and ask what changes are necessary to allow one of the four 10 kt modules to be sensitive to heavy Weakly Interacting Massive Particle (WIMP) dark matter. We show that with control over backgrounds and the use of low radioactivity argon, which may be commercially available on that timescale, along with a significant increase in light detection, one DUNE-like module gives a competitive WIMP detection sensitivity, particularly above a dark matter mass of 100 GeV.
