| Abstract Scope |
Being able to image and characterize the nature and characteristics of irradiation-induced defects (ID) at various damage levels in nuclear material is crucial for physics understanding, performance prediction and next-generation materials development. No characterization technique yet exists to provide detailed analysis of ID from less than 1 nm and at atomic level. According to Molecular Dynamics (MD) estimates, ID clusters that are less than 2 nm in size may contribute to ~97% of the overall defect population at low DPA, and these ‘invisible’ ID will have a significant contribution to the hardening effects on the irradiated material. AtomCRaD is a EUROfusion funded project to develop modern advanced Scanning Transmission Electron Microscopy (STEM) technique that couple with STEM image simulation and outputs from MD simulations to characterize small ID, < 2nm in diameter, in crystalline materials. In this talk, we will present the outcomes of AtomCRaD and limitations of this technique. |
