摘要
位于意大利格兰萨索国家实验室（INFN Laboratori Nazionali del Gran Sasso）的XENONnT实验，包含一个5.9吨的液氙时间投影室，周围环绕着装有仪器的中子否决系统，整体置于一个μ子否决水罐中。得益于广泛的屏蔽和先进的纯化技术以降低天然放射性，在时间投影室内部（1, 30）keV能区达到了（15.8 ± 1.3）事件/（吨·年·keV）的极低本底水平。因此，XENONnT对与暗物质和中微子相互作用相关的各种稀有现象具有高灵敏度，这些现象既涵盖粒子物理标准模型之内，也超越其外，尤其侧重于直接探测弱相互作用大质量粒子（WIMPs）形式的暗物质。从2021年5月到2021年12月，XENONnT在稀有事件搜索模式下累积了总计一吨·年的曝光量。本文详细描述了信噪重建方法、事件筛选程序、探测器响应校准，并概述了该时间段内的探测器性能。这项工作为我们在报告XENONnT物理结果时所采用的“盲分析”方法建立了基础框架。
