| Abstract Scope |
A Helium ion implantation system was developed to evaluate radiation damage of bulk scale HT-9 nuclear application steel. A novel high-energy binary degrader system was designed to provide uniform Helium ion implantation of 5 separate 100 μm thin SSJ2 tensile test specimens at once. The binary degrader is designed to provide 165 discrete energy levels, stopping the Helium ions throughout the HT-9 sample depth. It was shown using SRIM simulations that the degrader will provide the discrete energy Helium ion implantation levels as expected. The LBL 88-Inch Cyclotron will provide a 26 MeV and 20 μA total current incident beam, and will achieve 0.5 at% Helium in each sample in about 3 days of constant beam run. The samples holder is designed to be water cooled and instrumented in order to avoid annealing of the irradiation defects. |
