Description
CUPID is a next-generation tonne-scale bolometric neutrinoless double
beta decay experiment to probe the Majorana nature of neutrinos and
discover Lepton Number Violation if the effective neutrino mass is
greater than 10 meV. CUPID will be built on experience, expertise and
lessons learned in CUORE, and will be installed in the current CUORE
infrastructure in the Gran Sasso underground laboratory. The CUPID
detector technology, successfully tested in the CUPID-Mo experiment, is
based on scintillating bolometers of Li2MoO4 enriched in the isotope of
interest 100Mo. In order to achieve its ambitious science goals, CUPID
aims to reduce the backgrounds in the region of interest by a factor 100
with respect to CUORE. This performance will be achieved by introducing
the high efficiently alpha/beta discrimination demonstrated by the
CUPID-0 and CUPID-Mo experiments, and using a high transition energy
double beta decay nucleus such as 100Mo to minimize the impact of the
gamma background. CUPID will consist of about 1500 hybrid heat-light
detectors for a total isotope mass of 250 kg. The CUPID scientific reach
is supported by a detailed and safe background model that uses CUORE,
CUPID-Mo and CUPID-0 results. The required performance
in terms of energy resolution, alpha rejection factor and crystal purity
have already been demonstrated and will be presented.
