| Abstract Scope |
Commissioned in 2022, the ATLAS Materials Irradiation Station (AMIS) at Argonne National Laboratory focuses on irradiating nuclear fuels and structural materials. Situated within the Argonne Tandem Linac Accelerator System (ATLAS), AMIS delivers stable isotopes at energies up to 1.5 MeV/u. Recent experiments have concentrated on Xe and Fe, achieving energies of up to 200 MeV and 80 MeV, respectively, with ion penetrations ranging from 5-20 μm based on ion and substrate. Utilizing high ion fluxes of up to 1x1013 ions/cm2-s, AMIS can reach damage levels in the hundreds of DPA or equivalent fission gas densities of 2x1022 fissions/cm3 in days. This high-penetration high-damage rate capability supports unique experiments on reactor core materials, such as through irradiations of coatings, interface stability studies on the multi-micron scale, micromechanical testing of larger uniform damage regions, and Xe implantations for fission gas bubble studies. Recent upgrades have extended the irradiation temperature range from 50 °C - 700 °C up to 1500 °C and integrated an IR camera to track localized beam heating. The current capabilities, on-going upgrades, and recent experiments will be discussed.
