Investigation of the Energy Resolution Scaling in CUORE Bolometers

ORAL

Abstract

The Cryogenic Underground Observatory for Rare Events (CUORE) is an experiment searching for neutrinoless double beta decay in a ton-scale detector, located at the Gran Sasso National Laboratory in Italy. Utilizing a detector comprised of TeO2 crystals, CUORE operates at millikelvin temperatures to achieve sensitive measurements of temperature fluctuations from deposited energy.

The excellent energy resolution of the bolometric detectors is critical to the search for neutrinoless double beta decay and other rare events. To reliably evaluate the detector performance and handle the uncertainties in the region of interest, we model our signals empirically and characterize the detector response by scaling the energy resolution as a function of energy. We discuss the method used in the CUORE 2-ton-year analysis.
