Abstract

The results of analytical estimates and computer simulations of the primary radiation damage level in the number of displacements per atom (dpa) in solids are presented and compared, taking into account the material sputtering under ion bombardment. Calculations were performed for the bombardment of carbon-based materials by Ar+, Ne+, and N+ ions with energies of 2–30 keV, when considerable ion-induced changes in the material’s structure are observed. A comparison shows the close fit of the analytical and computer calculations.
