Tungsten is the candidate for plasma facing materials (PFMs) in the fusion reactor. It will be simultaneously irradiated by hydrogen isotopes and helium (He) produced by D-T fusion reaction. In this study, simultaneous He-H implantation was performed and the retention behavior was evaluated by high temperature thermal desorption spectroscopy (HT-TDS). Experimental results showed that He retention behavior was affected by the incident hydrogen to a large extent.
