摘要
The GERmanium Detector Array (GERDA) 是位于意大利 Laboratori Nazionali del Gran Sasso 的低本底实验，旨在寻找 Ge 衰变为 Se+2e 的无中微子双 beta 衰变。GERDA 的设计分为两个阶段。于 2015 年 12 月开始的 Phase II 具有几项新特性，包括 30 个新的 Ge 探测器。这些探测器是根据 Broad Energy Germanium (BEGe) 探测器设计制造的，与以往广泛使用的类型相比，具有更好的本底甄别能力和能量分辨率。在安装之前，这些新的 BEGe 探测器被安装在真空低温恒温器中，并在比利时的 HADES 地下实验室进行了详细的特性表征。本文描述了这些探测器在真空环境下运行时的特性与整体性能。此次特性表征活动不仅为 GERDA Phase II 的数据收集与分析提供了直接输入，还允许研究探测器现象、探测器相关性，以及测试脉冲形状模拟代码的可靠性。
