Abstract

The characteristics of detectors based on silicon carbide (SiC) before and after irradiation with integral neutron fluxes of 5.11 × 1013 and 5.39 × 1014 n/cm2 are presented. On the samples irradiated with the maximum fluence, using alpha particles, a deterioration in the energy resolution by an order of magnitude and a decrease in the efficiency of charge collection by ∼25% are shown.
