摘要:
The interaction between deuterium and radiation-induced point defects in tungsten and the stages of their transformation and annealing are investigated by means of thermal-desorption spectroscopy. Primary defects, mainly vacancies, are created using 10-keV D+ ions at room temperature. In investigating the evolution of radiation-induced defects, irradiated samples are annealed at temperatures of 550–1400 K and the subsequent filling of defects is carried out by deuterium after sample irradiation with D3 + ions with an energy of 0.67 keV/deuteron at room temperature. The characteristic positions of thermal desorption peaks, as well as the temperatures of vacancy clusterization and annealing of defects, are determined. © 2016, Pleiades Publishing, Ltd.
