The paper presents the results of a study of the effect of proton and ion radiation on structural changes in nitride ceramics, which have a high potential for using as a structural material for GenIV nuclear reactors. Proton beams with an energy of 1.5 MeV and low-energy helium (He 2+ ) and carbon (C 2+ ) ions with an energy of 40 keV were used, to simulate defect formation ...
