Energy resolution and detector response in CUORE

The Cryogenic Underground Observatory for Rare Events (CUORE) is an experiment searching for neutrinoless double beta decay in a ton-scale detector, located in the Gran Sasso National Laboratory (LNGS), Italy. The experiment is a highly sensitive calorimeter, maintained at millikelvin temperatures, detecting temperature fluctuations from energy deposits in TeO2 crystals. The excellent energy resolution of the bolometric detectors is critical to the search for neutrinoless double beta decay and other rare events. It may be degraded by increases in the noise. We discuss efforts to improve the energy resolution by reducing the noise from various sources, including correlation studies between the bolometric detector and seismic activity.
