Abstract: We report the results of massive parallel molecular dynamics simulations of high-energy radiation damage in phosphate glasses. This damage is created by overlapping multiple 70 keV collision cascades. We quantify different aspects of radiation-induced structural changes including at different stages of damage development, including coordination numbers, cluster sizes and density. The overall trend is that radiation damage causes polymerisation of the glass network and the loss of small and isolated clusters, however the details of this response vary with different glass compositions. • Radiation damage in iron phosphate glasses causes polymerization of the PO 4 network, excluding iron-oxygen bonds. • Anomalous 5-coordinated phosphorus atoms are produced by radiation cascades at the expense of 4-coordinated atoms. • High energy 70 keV cascades severely limit the degree of recovery of the above effects compared to low energy 4 keV cascades.
