AbstraktAbstract

The SuperNEMO experiment aims to search for neutrinoless double beta decay. Whilst the standard approach relies on detecting the sum of the kinetic energy of two emitted electrons, SuperNEMO has an additional tracking detector, enabling investigation of kinematic parameters of the decay and further background suppression through post-processing. Comprising 2034 drift cells operating in Geiger mode, the tracking detector measures both the vertical position of passing particles and the horizontal distance of their trajectories from the central anode wire. Consequently, each tracker hit is represented by a horizontally aligned circle centred at the anode wire with measured radius and vertical position. When viewed from above, the reconstructed trajectory should be tangent to these circles. Without a magnetic field applied, all particles are expected to follow a straight linear path. The primary challenge lies in the horizontal plane. A method based on the Legendre transform is utilised.
