摘要
CUORE 实验是目前世界上最大的量热实验。该探测器由 988 块 TeO2 晶体阵列组成，总质量为 742 kg。CUORE 目前正在意大利的 Gran Sasso 国家实验室采集数据，搜寻 130Te 的无中微子双 beta 衰变。一台大型定制无液氦低温恒温器能够达到并维持约 10 mK 的基础温度，这是探测器实现最佳运行所需的。该装置的设计旨在实现低噪声环境，并使其对实验的放射性本底贡献降至最低。在本文中，我们概述了 CUORE 低温恒温器及其所有子系统的描述，重点介绍了为满足严格要求而确定的解决方案。我们简要说明了低温恒温器调试的各个阶段，并强调了每次实现的相关步骤和里程碑。最后，我们描述了 CUORE 成功的降温过程。
