Light Detector R&D for CUORE/CUPID

The Cryogenic Underground Observatory for Rare Events (CUORE) is a tonne-scale experiment searching for neutrinoless double beta decay (0νββ). The particle detector consists of 988 TeO₂ crystal bolometers. The primary physics goal of the experiment is the observation of 0νββ, which would contribute to understanding leptogenesis as well as the neutrino mass hierarchy. The CUORE Upgrade with Particle IDentification (CUPID) is a next-generation neutrinoless double beta decay experiment with key improvements, one of which will be the addition of light readout via Li₂MoO₄ scintillating bolometers enriched with ¹⁰⁰Mo. The scintillating bolometers will be equipped with Neganov-Trofimov-Luke (NTL) enhanced light detectors to improve CUPID's sensitivity by mitigating alpha background. This poster will discuss the design of these NTL light detectors as well as the planned production and testing at Yale.
