| 内容記述 | A comprehensive analysis of collected dust particles in the Joint European Torus ITER-like Wall (JET-ILW) after the first campaign in 2011-2012[1] has been carried out at the International Fusion Energy Research Centre (IFERC) in order to identify dust characteristics such as structures, material components and hydrogen isotope retention. Analysis of the cross-section structure as well as surface one began with from a large-size dust particle (~100 m). For the flake-type beryllium (Be)-based dust, it was found that the damaged Be crystal structure contained a larger oxygen component near the surface (~2 m). The specific dust flake of beryllium oxide in the experiment device was shown for the first time. Deuterium retention in small weight of dust particles (4.4 mg) was evaluated to be 1.2 x 1021 atoms/g by TDS, which estimated to be 8.2 x 1020 atoms for entire dust particles collected from the inner divertor (0.7 g). This result firstly suggests that a contribution of dust particles to the total retention in the experiment was small, i.e. less than 1% of the total retention in deposition layers of the inner divertor target. | |||||
