Abstract

The effect of incident ion beam flux on the blister formation in annealed polycrystalline niobium and vanadium has been investigated for 0.5-MeV He+ and 0.25-MeV D+ projectiles. For the He+ ions the flux was varied from 1 × 1013 ions/(cm2-sec) to 1 × 1015 ions/(cm2-sec), the targets were held at 900°C, and the total dose was varied from 0.1 to 1.0 C/cm2. For the D+ ion irradiation the flux was varied from 1 × 1014 to 1 × 1015 ions/(cm2-sec), the niobium targets were held at 700°C, and the total dose was 2.0 C/cm2. For both the helium implanted vanadium and niobium the blister density shows a stronger flux dependence than the average blister diameter. For deuteron implanted niobium the blister size increased as the flux was increased from 1 × 1014 to 1 × 1015 ions/(cm2-sec).
