Denoising Algorithms for the CUORE Experiment

The Cryogenic Underground Observatory for Rare Events (CUORE) experiment is an ongoing search for neutrinoless double beta decay located at the Gran Sasso National Laboratory (LNGS) in Italy. Recent work has found that the CUORE calorimeters are sensitive to acoustic and seismic events originating from outside the detector at LNGS. To measure the effect of these mechanical disturbances on the calorimeter signals, diagnostic devices including microphones and accelerometers were installed around the CUORE cryostat. Here I will present how different denoising algorithms use the information from these devices to remove microphonic noise from low-temperature calorimeters, including the CUORE NTD bolometer channels. I will also show how denoising improves the energy resolution of these detectors and discuss plans for implementing robust denoising procedures in later experiments.
