Characterization of newly developed large area SiC sensors for the NUMEN experiment

Abstract: First prototypes of large area, p-n junction, silicon carbide (SiC) detectors have been produced as part of an ongoing programme to develop a new particle identification wall for the focal plane detector of the MAGNEX magnetic spectrometer, in preparation for future NUMEN experimental campaigns. First characterizations of sensors from two wafers obtained with epitaxial silicon carbide growth and with different doping concentration are presented. Current (I-V) and capacitance (C-V) characteristics are investigated in order to determine the full depletion voltage and the doping profile. Radioactive {\alpha}-sources are used to measure the energy resolution and estimate the depletion depth.
