Abstract: In the paper, a possibility of multiply charged ⁵⁶Fe ions beams formation for imitation irradiation of reactor materials with using the IAP NASU accelerator mass spectrometer is considered. There are iron ions of various charge states (up to ⁵⁶Fe⁸⁺) in obtained mass spectra. Despite of the ion current decreases with increasing charge state, multicharged ions can be used to irradiate specimens when larger ion energy is required. It is shown defect formation rate for ⁵⁶Fe sample irradiated by ⁵⁶Fe²⁺ ions with energy 2.52 MeV is 2.7⋅10^-3 dpa/s.

Keywords: beam, irradiation, multiply charged ion, iron ions, mass spectrum, dpa/s.
