Improving the energy calibration of CUORE-0 and CUORE

The Cryogenic Underground Observatory for Rare Events (CUORE) is a ton-scale cryogenic experiment designed to search for neutrinoless double-beta ($0\nu\beta\beta$) decay of $^{130}$Te. The experiment consists of 988 ultracold TeO$_2$ bolometric crystals arranged into 19 towers, which act as both the $0\nu\beta\beta$ decay sources and detectors. CUORE-0, an experiment using a single CUORE-like tower, completed physics data-taking in 2015 and set a new limit on the $0\nu\beta\beta$ decay half-life of $^{130}$Te. CUORE installation is scheduled to be completed this year with commissioning and data taking to begin soon thereafter. I will discuss the analysis and results from CUORE-0, focusing on energy calibration, and the analysis techniques and calibration hardware that will allow us to improve our understanding of the detector energy scale in CUORE.
