The CUPID-0 detector hosted at the Laboratori Nazionali del Gran Sasso, Italy, is the first large array of enriched scintillating cryogenic detectors for the investigation of Se neutrinoless double-beta decay ( ). CUPID-0 aims at measuring a background index in the region of interest (RoI) for at the level of 10 counts/(keV kg years), the lowest value ever measured using cryogenic detectors. CUPID-0 operates an array of Zn Se scintillating bolometers coupled with bolometric light detectors, with a state of the art technology for background suppression and thorough protocols and procedures for the detector preparation and construction. In this paper, the different phases of the detector design and construction will be presented, from the material selection (for the absorber production) to the new and innovative detector structure. The successful construction of the detector lead to promising preliminary detector performance which is discussed here.
位于意大利格兰萨索国家实验室的CUPID - 0探测器，是用于研究硒无中微子双β衰变（ ）的首个大型富集闪烁低温探测器阵列。CUPID - 0旨在测量感兴趣区域（RoI）内 的本底指数，达到10 计数/（keV·kg·年）的水平，这是使用低温探测器测量到的最低值。CUPID - 0运行着一个由Zn Se闪烁测辐射热计与测辐射热光探测器耦合而成的阵列，采用了抑制本底的先进技术以及探测器制备和构建的完善方案与程序。本文将介绍探测器设计和构建的不同阶段，从材料选择（用于吸收体生产）到新型创新的探测器结构。探测器的成功构建带来了有前景的初步探测器性能，本文将对此进行讨论。
