First wall ablations with high-flux pulsed proton beams and UV laser lights for IFE reactor design database

Two kinds of experiments were performed to observe the surface ablation and crater formation with a pulsed intense ion beam and a UV laser beam. The former particle beam specie was proton and the latter laser was ArF. These beams were used to irradiate the candidate surface materials for the inertial fusion energy (IFE) reactor walls. Our interests for this study arise from the modeling of the first wall ablation of the future candidate IFE reactors. All of the experimental results were gathered and compared with our former results, for the compilation of the database of the IFE reactor designs.
