Abstract Scope |
Helium effects in materials are relevant for fission and fusion applications. Bulk materials damage is considered in fission applications while surface near damage is a result of materials exposure to a fusion environment. Traditionally we perform these studies either in reactor, spallation or ion beam accelerator environments. However, the helium ion beam microscope allows for direct Helium implantation in a surface on a very localized scale. This allows to examine several doses at one single material in the same session greatly accelerating the process. Furthermore, the post irradiation characterization via AFM and nanoindentation generates large number of data on different materials providing swelling and Helium induced hardening information. Selected materials will be investigated using TEM to evaluate the mechanisms. We show data on Cu, V, W, Ti and SiC in this study. |
