N. Yoshida et al., DAMAGE AND DEUTERIUM RETENTION OF BERYLLIUM DUE TO LOW-ENERGY DEUTERIUM ION IRRADIATION, Fusion technology, 30(3), 1996, pp. 798-801
Thermal desorption of deuterium(D) from 8-keV D-ion irradiated berylli
um(Be) above room temperature was correlated with microstructural chan
ges during irradiation and annealing to understand the underlying mech
anism of retention and trapping of D. D bubbles are formed at all exam
ined temperatures between 300K and 873K. Large roundish bubbles above
200nm are especially formed above 573K. They remain even after anneali
ng up to 973K. Strong retention of D by the bubbles occurs for the irr
adiation up to 673K.
