Abstract

This study intends to investigate cascade damage structure produced by energetic ion irradiation. Cascade damage structure is preserved at low temperature below stage I where interstitial atoms begin to migrate. Then positron beam is implanted to the irradiated surface as a vacancy probe to evaluate vacancy concentration remained in the irradiated specimens. By this method, defect production efficiency was evaluated for iron irradiated with proton and carbon ions. The defect production efficiency values indicate enhanced recombination for carbon irradiation due to primary knock-on atoms (PKA) with higher energies.
