摘要
CUPID 合作组正在设计一台吨量级、无本底的探测器，以搜寻双贝塔衰变，其灵敏度足以完整探索对应于倒转中微子质量层级情形的参数空间。CUPID 的演示装置之一 CUPID-Mo 已证明富集的 LiMoO 晶体作为无中微子双贝塔衰变搜寻的合适探测器具有潜力。在这项工作中，我们对立方晶体进行了表征，与 CUPID-Mo 所用的圆柱晶体相比，立方晶体更利于构建紧密排布阵列。我们测得感兴趣区平均能量分辨率为 (6.70.6) keV FWHM，接近 CUPID 的 5 keV FWHM 目标。我们评估了在有和无增强闪烁光收集效率的反射箔情况下对 粒子的甄别能力，证明 CUPID 的基线设计已确保对此 诱发本底贡献的完全抑制。我们还利用所采集数据验证了模拟光收集效率的蒙特卡洛模拟，这将有助于探测器的进一步优化。
