| Abstract Scope |
Contemporary methods to investigate the role of radiation damage and transmutation gas production (H, He) by ion irradiation are to conduct individual experiments, performed at fixed doses (dpa) and gas implantation values (appm). In utilizing controlled beam-line shutters, broad scopes of the appm/dpa parameter space for each shuttered ion beam-line can be explored within a single irradiation experiment. This approach significantly increases the sample throughput by several orders of magnitude, thus accessing numerous combinations of gas implantation and dpa values. Lithography and atomic layer deposition enable precisely discretized sample geometries, facilitating subsequent microscopical investigations of the irradiated microstructure at known implantation doses and damage rates. The application of this gas-gradient technique to predict fast reactor irradiation of alloy T91 using a He-gradient, and fusion blanket conditions using both H- and Hegradients will be presented, along with (S)TEM results of irradiated microstructures.
