| Abstract Scope |
Recent advancements at the Michigan Ion Beam Laboratory of the University of Michigan allow for the creation of lateral and depth-modulated transmutation gas gradients using a shuttered triple-ion irradiation system, which can produce a wide range of appm/dpa values for hydrogen and helium ion implantation in a single specimen. Here, we explore several results in characterizing the radiation damage utilizing FIB and S/TEM. The focus lies in the characterization of swelling and microstructural development as a function of several appm/dpa (H, He) combinations at fixed dose levels, damage rate, and target temperature. Comparative results can be made on the role of implanted helium in terms of cavity production, as well as isolating the role of H in relation to swelling. This high throughput technique covers a wide range of fission and fusion reactor irradiation conditions, enabling rapid and validated ion irradiation testing of potential structural materials. |
