Investigation of Background Sources in CUORE

The Cryogenic Underground Observatory for Rare Events (CUORE) experiment is designed to search for the process of neutrinoless double-beta decay in ¹³⁰Te. The signature of this process would manifest as a monoenergetic peak at the Q-value of the decay that, if observed, would confirm lepton number violation and the Majorana nature of the neutrino. As this is a process beyond the Standard Model and expected to be very rare, understanding the background sources in CUORE is essential to enhancing signal sensitivity. Using the geometry of the CUORE detector, which consists of a hexagonal array of 988 TeO₂ bolometers, I will present my investigation of the positional dependence of the backgrounds in the array to identify localized background sources in CUORE. Implications on future generation of bolometer detectors for neutrinoless double-beta decay will also be discussed.
