| Abstract;From fusion safety point of view, studies on hot atomchemical behavior of energetic tritium implanted into plasma facing materials have been carried out. This is also an important subject for high energy chemistry. In the present study we investigated the chemical behavior of energetic deuterium implanted into graphite by Thermal Desorption Spectroscopy (TDS). TDS measurements were made on D2 and CD4 from surface layer of pyrolytic graphite cleavage surfaces after 1 keV D2+ irradiation to 1.0*1022 D/m2 at irradiation temperatures from 173 K to 673 K. From the TDS results, we discussed the dependence of irradiation temperature on release behavior of D2 and CD4. (author abst.) |
