The CUPID-Mo experiment for neutrinoless double-beta decay: performance and prospects
CUPID-Mo is a bolometric experiment to search for neutrinoless double-beta decay (0 ???) of 100Mo. In this article, we detail the CUPID-Mo detector concept, assembly and installation in the Modane underground laboratory, providing results from the first datasets. The CUPID-Mo detector consists of an array of 20 100Mo -enriched 0.2 kg Li 2MoO 4 crystals operated as scintillating bolometers at ?20mK. The Li 2MoO 4 crystals are complemented by 20 thin Ge optical bolometers to reject ? events by the simultaneous detection of heat and scintillation light.
