The R&D activity performed during the last years proved the potential of ZnSe scintillating bolometers to the search for neutrino-less double beta decay, motivating the realization of the first large-mass experiment based on this technology: CUPID-0. The isotopic enrichment in [Formula: see text]Se, the Zn[Formula: see text]Se crystals growth, as well as the light detectors production have been accomplished, and the experiment is now in construction at Laboratori Nazionali del Gran Sasso (Italy). In this paper we present the results obtained testing the first three Zn[Formula: see text]Se crystals operated as scintillating bolometers, and we prove that their performance in terms of energy resolution, background rejection capability and intrinsic radio-purity complies with the requirements of CUPID-0.
过去几年进行的研发活动证明了ZnSe闪烁测热计在寻找无中微子双β衰变方面的潜力,这推动了基于该技术的首个大质量实验的实现:CUPID-0。[公式:见原文]Se的同位素富集、Zn[公式:见原文]Se晶体生长以及光探测器生产均已完成,该实验目前正在意大利大萨索国家实验室建设中。在本文中,我们展示了测试首批三个用作闪烁测热计的Zn[公式:见原文]Se晶体所获得的结果,并证明它们在能量分辨率、本底抑制能力和固有放射性纯度方面的性能符合CUPID-0的要求。
