Damage calculation in compound materials under neutron and ion irradiation

A method for displacement damage rate calculations in compound materials under neutron and ion accelerator irradiation is proposed. The method is especially suitable for materials with significantly different masses of species. Range and damage depth profiles in HTSC ceramics for different He-ion projectile energies were calculated. Partial contributions of each species to displacement damage and spectral-averaged partial damage cross sections for two neutron irradiation conditions were also calculated. The developed code provides a quick and reliable way of comparison of the displacement damage under neutron and ion irradiation. Helium ion doses equivalent by dpa to neutron irradiation in ORR and YAYOI reactors were obtained.
