摘要：

稀有事件低温地下观测站（英语：Cryogenic Underground Observatory for Rare Events，简称CUORE）是一个在$^{130}$ Te和其他稀有过程中寻找无中微子双β衰变（英语：Neutrinoless double beta decay，简称$0νββ$）的实验。CUORE是一种低温探测器，由988 TeO $_2$测辐射热计组成，总质量约为741 kg。该探测器正在意大利Gran Sasso的Nazionali建造，将于2015年开始收集数据。如果达到0.01计数/（keV $\cdot$ kg $\cdot$ y）的目标本底，在5年的数据采集中，CUORE在90\%C. L时的半衰期灵敏度约为$1\times 10^{26}$ y。作为实现CUORE的第一步，已经组装并正在运行一个较小的实验CUORE-0，以测试和演示CUORE的预期性能。该探测器是一个由52个类似CUORE的测辐射热计组成的单塔，于2013年春季开始采集数据。将讨论CUORE的现状和前景，并将提供第一个CUORE-0数据。

英文摘要：

The Cryogenic Underground Observatory for Rare Events (CUORE) is an experiment to search for neutrinoless double beta decay ($0νββ$) in $^{130}$Te and other rare processes. CUORE is a cryogenic detector composed of 988 TeO$_2$ bolometers for a total mass of about 741 kg. The detector is being constructed at the Laboratori Nazionali del Gran Sasso, Italy, where it will start taking data in 2015. If the target background of 0.01 counts/(keV$\cdot$kg$\cdot$y) will be reached, in five years of data taking CUORE will have an half life sensitivity around $1\times 10^{26}$ y at 90\% C.L. As a first step towards CUORE a smaller experiment CUORE-0, constructed to test and demonstrate the performances expected for CUORE, has been assembled and is running. The detector is a single tower of 52 CUORE-like bolometers that started taking data in spring 2013. The status and perspectives of CUORE will be discussed, and the first CUORE-0 data will be presented.
