Abstract
The characteristics of detectors based on silicon (Si) and silicon carbide (SiC), which were irradiated with integral neutron fluxes Φ = 5.1 × 1013, 5.4 × 1014, and 3.4 × 1015 neutrons/cm2 (1 MeV/Si), are presented. It was found that the conductivity of the sensitive region becomes close to its own for all irradiated samples. Using alfa particles, the authors found that, for Si detectors irradiated with a minimum flux of 5.1 × 1013 neutrons/cm2, the charge collection efficiency (η) does not exceed 1.5%. For SiC detectors irradiated with a similar flux, η = 96%, and η decreased to 70 and 1.5%, respectively, when irradiated with average and maximum fluxes. Thus, it is shown that the deterioration in the performance of SiC detectors occurs at significantly higher dose loads than when using Si devices.
期刊介绍：
Instruments and Experimental Techniques is an international peer reviewed journal that publishes reviews describing advanced methods for physical measurements and techniques and original articles that present techniques for physical measurements, principles of operation, design, methods of application, and analysis of the operation of physical instruments used in all fields of experimental physics and when conducting measurements using physical methods and instruments in astronomy, natural sciences, chemistry, biology, medicine, and ecology.
