Abstract
SuperNEMO, successor to the NEMO3 experiment, is looking for the neutrinoless double beta decay. Its unique design, combining both tracking and calorimetry techniques, provides essential topological informations. Indeed, fully reconstructing the event kinematics : allows a powerful background discrimination, would discriminate between the several hypothesized underlying mechanisms, but also gives access to a variety of event topologies which can be used to measure the different background contributions. The SuperNEMO software relies on a range of algorithms to ensure a faithful event reconstruction. The improved detector performance for $\gamma$ detection coupled to new $\gamma$-reconstruction algorithms, based on geometrical and Time-of-Flight criteria, will not only improve the measurements of the $\gamma$-emitting backgrounds ($^{208}$Tl, $^{214}$Bi...) but also increase the sensitivity for the search of $\beta\beta$-decays to the excited states.
