Present Status and Future Perspectives of the NEXT Experiment
Figure 28
Example of the reconstruction of a 137Cs track. The charge of the different SiPMs is split into slices of 4 mm in width in (a). One point is calculated for each slice using the barycentre method and the energy of the points is then associated with the measurement made in the cathode (b). A cubic spline is used to interconnect the different points. The result is shown in the bottom line: projection (c) and 3D image (d) of the reconstructed track [41], where the coordinate is the axis of the cylindrical TPC and define the orthogonal plane.
