CUORE is a tonne-scale cryogenic experiment located at the Laboratori Nazionali del Gran Sasso that exploits bolometric technique to search for neutrinoless double beta decay of $$^{130}{\hbox {Te}}$$ 130 Te . Thanks to its very low background and large mass, CUORE is also a powerful tool to study a broad class of phenomena, such as solar axions and WIMP scattering. The ability to conduct such sensitive searches crucially depends on the energy threshold, which has to be kept as low as possible. In this contribution, we show how the trigger algorithm affects the sensitivity to low-energy phenomena and the interpretation of the energy spectrum. In particular, we focus on the impact that the trigger algorithm has on the identification of the coincidence events among different crystals and, consequently, on the reconstruction of the background.

降低 CUORE 实验的能量阈值：表面 Alpha 事件重建的好处

CUORE 是一个吨级低温实验，位于Laboratori Nazionali del Gran Sasso，利用热辐射技术来寻找$$^{130}{\hbox {Te}}$$$$130 Te 的无中微子双β衰变。由于其非常低的背景和大质量，CUORE 还是研究范围广泛的现象（例如太阳轴子和 WIMP 散射）的强大工具。进行此类敏感搜索的能力关键取决于能量阈值，该阈值必须保持尽可能低。在这个贡献中，我们展示了触发算法如何影响对低能量现象的敏感性和能谱的解释。我们特别关注触发算法对识别不同晶体之间的重合事件的影响，从而对背景的重建产生影响。
