| 概要 | Blister formation and D retention in W have been investigated for low energy (similar to 55 +/- 15 eV), high flux (similar to 10(22) m(-2) s(-1)), high fluence (<= 4.5 x 10(26) m(-2)) ion bombardment at moderate temperature (similar to 573 K) in mixed species D + He plasmas in the linear divertor plasma simulator PISCES-A. The amount of D retained in W is found to decrease significantly when compared with that in W exposed to pure D plasmas, as measured with high resolution thermal desorption spectroscopy. Scanning electron microscopy observations reveal the suppression of the blisters, a surface feature known to drive up retention, in the D + He mixture plasma exposed W samples. |
