Description
The CROSS experiment, currently operating at the Canfranc Underground Laboratory (Spain), is dedicated to the search for neutrinoless double beta decay of $^{100}\mathrm{Mo}$.
CROSS employs enriched $\mathrm{Li_2MoO_4}$ and $\mathrm{TeO_2}$ crystals operated as cryogenic bolometers, together with a secondary bolometric readout of scintillation and Cherenkov light, enabling the discrimination of $\alpha$ events from $\beta/\gamma$ interactions.
In this poster, we present the event reconstruction pipeline based on the OCTOPUS software framework and report on the performance of both the $\mathrm{Li_2MoO_4}$ bolometers and the corresponding light detectors.
We describe the algorithms used to digitally trigger physical events from the continuously acquired data stream, reconstruct the relevant event parameters, correct for temperature-dependent gain fluctuations, calibrate the energy scale, identify non-physical pulses, and perform particle discrimination exploiting the different light yield of $\mathrm{Li_2MoO_4}$ scintillation signals for $\alpha$ and $\beta/\gamma$ particles.
Finally, we report on the detector performance in terms of energy and time resolution, effective light yield, and the efficiency of the various analysis stages.
