Description
CUPID — CUORE Upgrade with Particle Identification — is the ton-scale neutrinoless double beta decay (NLDBD) experiment at LNGS. CUPID will be mounted in the CUORE cryostat, leveraging the existing cryogenic infrastructure and a decade of experience operating the largest bolometer array in existence. CUPID will deploy 1600 Li2MoO4 scintillating bolometers with the dual heat-light readout to achieve a low-background search for NLDBD in the inverted ordering region of the neutrino mass parameter space. An even larger, possibly distributed bolometric array, CUPID-1T with over a metric ton of Mo-100, would be the next-generation experiment with sensitivity in the normal ordering region of neutrino masses. We will discuss the technological developments for CUPID, including the development of superconducting TES sensors with multiplexed readout, and novel detector concepts that could allow for a background-free searches for NLDBD.
