Tracking Crystal-Based Sources of CUORE Background

The Cryogenic Underground Observatory for Rare Events (CUORE) contains a bolometer-based detector with Te0₂ crystals that is used to search for neutrinoless double-beta decay in the isotope ¹³⁰Te. Searching for rare events such as neutrinoless double-beta decay requires a deep understanding of backgrounds. In particular, this project sought to identify crystal-based backgrounds by looking for correlations between the activities of certain isotopes and crystal parameters (e.g. when the crystal was created). This identification would allow the CUORE collaboration to be more confident about its understanding of the background spectrum. In this presentation, I will show the results from studies of the activities of multiple sources on the CUORE crystals in order to identify and track crystal-based contaminations.
