Calibration of the CUORE Detector Array

ORAL

Abstract

CUORE is a ton-scale cryogenic detector that will use an array of 988 $\textrm{TeO}_{2}$ bolometers to search for neutrinoless double-beta decay of ${}^{130}\textrm{Te}$. Calibration of the detector is essential to determine the energy scale, especially near the Q-value of the nuclear transition where the neutrinoless double-beta decay is expected as a monochromatic peak. The CUORE detector calibration system has been designed and built to uniformly irradiate the entire volume with low-temperature sources. It is necessary to mechnically cool the sources to 4 K to maintain the bolometers at their working points. In this talk I will give an overview of the detector calibration system and present the first results from its commissioning in the cryostat.
