| Research Abstract |
In this study, the quantitative evaluation of tritium recycling on the surface of plasma facing materials under the mixed ion implantations was performed. To propose tritium recycling model including the effect of materials, correlation between tritium recycling and irradiation damage of materials was elucidated. Deuterium retention behaviors in the tungsten(W) and sputtering behaviors for the carbon implanted W, HOPG and WC during hydrogen ion implantation were evaluated.
