CUORE是迄今为止唯一完全批准的1吨级无中微子双β衰变实验，其目标是仔细检查有效马约拉纳质量的倒置层次区域。CUORE目前正在Gran Sasso地下实验室建造，是一个988 TeO 2低温探测器阵列，包含200公斤的130 Te，无中微子双β衰变候选者。CUORE将于2012年开始收集数据。该项目的可行性已被Cuoricino证明，该试验直到2008年才获得数据，为期约五年，使用62个TeO 2低温探测器。Cuoricino将在2010年被CUORE-0取代，这是第一个安装在Cuoricino低温设施中的CUORE塔，它将在CUORE启动之前收集数据。本文报道了Cuoricino的最终结果，并讨论了CUORE-0和CUORE的潜力和最新技术水平。
CUORE is the only fully approved 1-ton size neutrinoless double beta decay experiment to date, with the goal of scrutinazing the inverted hierachy region for the effective Majorana mass. CUORE, presently being built in Gran Sasso Underground Laboratory, is an array of 988 TeO2 cryogenic detectors containing 200kg of 130Te, the neutrinoless double beta decay candidate. CUORE is due to start data taking in 2012. The feasibility of the project has been proved by Cuoricino, the pilot experiment that took data until 2008, for about five years, with 62 TeO2 cryogenic detectors. Cuoricino will be superseded in 2010 by CUORE-0, the first CUORE tower to be installed in Cuoricino cryogenic facility, which will take data until CUORE start. In this paper the final results of Cuoricino are reported, and CUORE-0 and CUORE potential and state of the art are discussed.
