Fast neutron detection with silicon carbide semiconductor

Silicon carbide (SiC) radiation detectors are being developed for high-temperature appliions in harsh radiation environments. Among these appliions are characterization of nuclear reactor fuel and detection of concealed fissionable materials, which both require the optimization of SiC fast neutron detectors for detection and quantifiion of fission neutrons.
