Transmission Electron Microscope/Atom Probe Visualization

Atom probe and transmission electron tomography data are analyzed on the bridge of the AlloSphere helping scientists understand the nature of nanoscale imperfections in steel which could lead to more stable fusion reactors. By visualizing data sets from different imaging techniques in a fully immersive stereoscopic environment, experimentalists can quickly gain insight into the spatial and compositional characteristics of microstructural features in materials. This dataset is a combination of transmission electron and atom probe tomograms which show a 1:1 association between He bubbles and oxide nanoclusters. Understanding this association is needed to design better materials for advanced nuclear reactors.

Key faculty and graduate student researchers associated with the project: Professor JoAnn Kuchera-Morin, Dennis Adderton, Kurt Kaminski, Kon-Hyong Kim, Hannah Wolfe, Tim Wood, Karl Yerkes & Keehong Youn.

This project was done in collaboration with Stephan Kraemer & Peter Wells.
