位于Gran Sasso国家实验室的XENON 1 T实验是对暗物质的最灵敏的直接探测实验，其形式是质量超过6，$GeV/$c^2$的弱相互作用粒子（WIMP）。探测器采用了双相时间投影室，目标中有2.0吨液态氙。在2016年10月至2018年2月期间收集了1 $\mathrm{tonne}\times\mathrm{year}$暴露的科学数据。本文报告了在此期间的检测器的性能，并介绍了数据分析的细节，导致最严格的排除限制各种WIMP核子相互作用模型的日期。特别是，信号重建，事件选择和校准的探测器响应信号和背景的相互作用在XENON 1 T进行了讨论。
The XENON1T experiment at the Laboratori Nazionali del Gran Sasso is the most sensitive direct detection experiment for dark matter in the form of weakly interacting particles (WIMPs) with masses above $6\,$GeV/$c^2$ scattering off nuclei. The detector employs a dual-phase time projection chamber with 2.0 tonnes of liquid xenon in the target. A one $\mathrm{tonne}\times\mathrm{year}$ exposure of science data was collected between October 2016 and February 2018. This article reports on the performance of the detector during this period and describes details of the data analysis that led to the most stringent exclusion limits on various WIMP-nucleon interaction models to date. In particular, signal reconstruction, event selection and calibration of the detector response to signal-like and background-like interactions in XENON1T are discussed.
