Saturated Pulse Recovery for CUORE

The CUORE (Cryogenic Underground Observatory for Rare Events) Experiment searches for neutrinoless double-beta decay (0νββ) using tellurium dioxide (TeO₂) crystals. High-energy events saturate the dynamic range of read-out electronics, leading to a maximum energy detection limit at ~30 MeV. This is a problem for two main reasons: (1) Understanding cosmogenic activation and related decay processes needs high energy muon detection and (2) Searches for tri-nucleon decay also require energies in such high ranges, both searches are limited by this saturation and the loss of information it causes. The goal of this research is to reconstruct saturated pulses and thus correctly characterize high-energy (30 MeV+) events in the CUORE Experiment. This reconstruction is done using the following experimentally-obtained parameters: time-above-saturation, voltage, and average pulses.

A first-order approximation is then performed: the purpose of this presentation is to show paths towards reconstruction, their characteristics, results, and comparisons with simulations.
