Design and Implementation of CERES, a Cryogenic Experiment to Reconstruct Energy Systematics in TeO2 bolometers

The Cryogenic Underground Observatory for Rare Events (CUORE) experiment, located beneath the Gran Sasso National Laboratory in Italy, employs an array of 988 TeO2 crystals operated at the level of 10 millikelvin to search for Beyond Standard Model neutrinoless double beta decay (0𝜈𝛽𝛽) events.

Given the narrow search region for 0𝜈𝛽𝛽, it is vital to understand the energy systematics. Recent studies have indicated that the energy resolution of these calorimetric detectors may also depend on the topological features of the events.

This presentation will focus on the design and implementation of an experiment, CERES, to investigate this phenomenon, as well as on the efforts to use a MEMS-based scanning device to inject light pulses across the face of a calorimeter crystal.
