The surface damage of W and Mo due to D+ bombardment
especially the blister formation and D retention in the surface layer of W
was systematically studied by means of SEM and D depth-profiling. The bombardment energies are of 100—1000eV with the D+ fluence from 11019 cm-2 to 11021 cm-2. The target temperatures are adjusted at room temperature
600C and 800 C
respectively
during the bombardment. Possible mechanisms are proposed to describe the observed phenomena.
