摘要
CUORE 是运行于格兰萨索国家实验室 (LNGS) 的吨级低温探测器，它利用二氧化碲量热器搜寻 Te 的无中微子双贝塔衰变。凭借其超低本底和大靶质量，CUORE 也适用于搜寻太阳轴子或 WIMP 散射等低能稀有事件。然而，进行此类高灵敏度搜寻需要将能量阈值降低至 10 keV。本文描述了为类 CUORE 探测器开发的低能分析技术，所用数据来自 CUORE-0（一个旨在验证 CUORE 组装程序和新清洗技术的单塔原型）于 2013 年 11 月至 2015 年 3 月期间采集的数据。我们详细解释了能量阈值优化、触发效率的连续监测、数据与事件选择以及低能区的能量校准。我们还展示了 CUORE-0 在 60 keV 以下的低能本底能谱。最后，我们利用 CUORE-0 的能量阈值和本底报告了 CUORE 对 WIMP 年调制效应的灵敏度，并估算了 CUORE-0 中核反冲导致的核淬灭因子的不确定性。
