 Project Description: Radiation damage represents the ultimate mesoscale scientific challenge, requiring the simultaneous understanding of processes from the atomic, through the mesoscale, to the engineering scales. Most radiation damage studies correlate dose in displacements per atom (DPA) to changes in material properties, even though changing nearly any condition or material parameter changes the DPA-property relationship. Therefore, a direct mesoscale measurement technique is needed to understand radiation damage's direct effects on material properties. This requires understanding the defect populations that create them. Our group has chosen transient grating (TG) spectroscopy as this mesoscale measurement technique, which we believe will be able to deconvolve the separate effects of radiation-induced defect populations on material properties by in-situ measurement of changes in the TG signal during material irradiation. Succeeding in this damage deconvolution will result in ultra-rapid qualification of radiation-resistant materials, and may help to solve decades-old questions about the long-term incubation of potentially disastrous radiation effects like void swelling and irradiation-induced creep.

 Project Description: The concept of "damage" remains difficult to quantify. If we had a universal way to measure damage, we would be able to better predict when materials would fail, measure their degradation during service, and design new ones to be both longer-lasting and more economical. The use of stored energy fingerprints is proposed as a way to quantify damage to materials from any damaging process. We focus on radiation damage as an ideal way to make all the types of defects found in most materials. A two-pronged experimental and simulation approach will be used to quantify and understand these stored energy fingerprints, relating them directly to the defects created by damage. Immediate applications of this work range from reconciling the differences between ion and neutron irradiation, to predicting material property changes due to radiation damage, to verifying the historical usage of uranium enrichment centrifuges.
