Research Abstract

Control of hydrogen isotope retention in plasma-facing components (PFC) is essential to establish steady-state operation. Understanding of dynamic behavior of hydrogen isotope retention in PFC is quite important related to optimization of the timing of fueling and flux dependence of chemical sputtering, and so on. However, these phenomena have not been understood yet, primarily due to the lack of proper plasma-surface analyses under plasma exposure. In this study, we have investigated deuterium retention in graphite under and after plasma exposure by using a device of PS-DIBA (Plasma Surface Dynamics with Ion Beam Analysis), which makes it possible to carry out in-situ ion beam analysis of deuterium retention. We have clearly observed the dynamics retention in graphite material under deuterium plasma exposure, and analyzed the release time of dynamically retained deuterium particles depending on the deuterium ion flux. We also investigated dynamic behavior of hydrogen isotope exchange between deuterium and hydrogen species.
