位于格兰萨索国家实验室（LNGS）的XENON1T实验是首个以超过吨级的液态氙为靶物质的弱相互作用大质量粒子（WIMP）暗物质探测器。在其3.2吨液态氙存量中，2.0吨构成了双相时间投影室的有效靶。利用低本底光电倍增管探测粒子相互作用产生的闪烁和电离信号。本文介绍了XENON1T仪器及其子系统，以及实现前所未有的低本底水平的策略。还展示了有关探测器响应和子系统性能的初步结果。
The XENON1T experiment at the Laboratori Nazionali del Gran Sasso (LNGS) is the first WIMP dark matter detector operating with a liquid xenon target mass above the ton-scale. Out of its 3.2t liquid xenon inventory, 2.0t constitute the active target of the dual-phase time projection chamber. The scintillation and ionization signals from particle interactions are detected with low-background photomultipliers. This article describes the XENON1T instrument and its subsystems as well as strategies to achieve an unprecedented low background level. First results on the detector response and the performance of the subsystems are also presented.
