Description

The analysis of cryogenic detector data is known to be challenging for any experiment. The main difficulty for the analysis of these detectors is the background rejection since they suffer from the presence of several different pulse shapes which need to be discriminated down to very low SNR
conditions.
Background reduction is particularly important for the NUCLEUS experiment since the aim is to produce ultra-low threshold ( ~ 20 eV) cryogenic detectors to measure coherent elastic neutrino-nucleus scattering at the Chooz nuclear power plant. The low threshold is necessary due to the low
nuclear recoil signal produced which is under 1 keV.
In this poster the data analysis procedure performed for the NUCLEUS experiment with the DIANA analysis framework is presented along with several upgrades made to the framework since the initial implementation in the CUORE neutrinoless double-beta decay experiment.
