摘要
我们报告了CUORE实验中通过-going μ子的三维重建，CUORE是一套寻找中中性双β衰变()的 cryogenic 热力学阵列，利用探测器的分割结构实现。由于探测器的慢时响应，无法进行时间飞行估计。因此，采用基于探测器整体几何信息的多目标优化算法进行轨迹重建。我们测量了位于意大利格兰萨索实验室下的宇宙射线μ子通量，发现我们的数值与其他进行类似测量的实验结果良好一致。据我们所知，这项工作是首次在毫开尔文级 cryogenic 探测器阵列中实现三维粒子跟踪和通过-going μ子的重建，并能够对每一次事件进行角度确定。本工作的分析对验证CUDO中与μ子相关的背景、以及对后续探测器响应和由宇宙射线μ子引起的延迟产物进行研究具有重要意义。
