摘要
位于格兰萨索地下实验室 (LNGS) 的锗探测器阵列 (GERDA) 旨在搜寻Ge 的无中微子双贝塔衰变 ()。由富集Ge 分数材料制成的锗探测器在此衰变中同时充当源和探测器。在实验的第一阶段，主要使用了来自先前实验的翻新半同轴 Ge 探测器。对于即将到来的第二阶段，生产了 30 个新型富集Ge 的宽能锗 (BEGe) 型探测器。其中一部分探测器已在第一阶段部署于 GERDA 中。本文综述了这些 BEGe 探测器的完整生产链，包括同位素富集、纯化、晶体生长和二极管制造。文中描述了在优化质量产额以及最小化加工过程中富集Ge 锗暴露于宇宙辐射方面所做的努力。此外，还讨论了首批七个 BEGe 探测器在真空低温恒温器中的表征测量及其在液氩中的长期行为。探测器性能满足 GERDA 第二阶段物理目标的要求。
