Large mass bolometers, thanks to their good energy resolution and high radiopurity, can be used for rare event searches, such as neutrinoless double beta decay or dark matter direct detection. The bolometric technique has been adopted by the CUORE experiment which is composed by an array of 988 tellurium dioxide bolometers with a total active mass of 741 kg. The experiment started taking data in April 2017 at the Laboratori Nazionali del Gran Sasso (LNGS), Italy, with the scientific goal of searching for neutrinoless double beta decay of 130-Te. Given the increasing number of channels to be acquired, the readout chain became an important aspect of the construction of bolometer arrays. The CUORE data acquisition system here described, called Apollo, was initially developed for CUORE, but its high modularity and flexibility make it possible to use it also in other experiments, regardless of the specific characteristics of the setup such as the number of channels and the bolometer characteristics. Indeed, it has been used not only in CUORE but also in its predecessor CUORE-0, R&D projects and upgrades such as CUPID-0.

CUORE 数据采集系统

大质量辐射热计由于其良好的能量分辨率和高辐射纯度,可用于罕见事件搜索,例如无中微子双 β 衰变或暗物质直接探测。CUORE 实验采用了辐射热测量技术,该实验由 988 个二氧化碲辐射热计阵列组成,总活性质量为 741 kg。该实验于 2017 年 4 月在意大利国家大萨索实验室 (LNGS) 开始采集数据,其科学目标是寻找 130-Te 的无中微子双 β 衰变。鉴于要获取的通道数量不断增加,读出链成为构建辐射热计阵列的一个重要方面。这里描述的 CUORE 数据采集系统,称为 Apollo,最初是为 CUORE 开发的,但它的高度模块化和灵活性使其也可以在其他实验中使用它,而不管设置的具体特性如何,例如通道数量和辐射热计特性。事实上,它不仅在 CUORE 中使用,而且还用于其前身 CUORE-0、研发项目和升级项目,例如 CUPID-0。
