The X-ray Science Division (XSD) at Argonne National Laboratory invites applications for a postdoctoral researcher position to develop novel X-ray diffraction techniques for 3-dimensional imaging. The postdoctoral appointee will enhance the spatial resolution of high-energy X-ray diffraction microscopy (HEDM)[1] at the Advanced Photon Source (APS) by exploiting its high brilliance and coherence and use this technique to study the effect of irradiation on the properties of structural materials. The appointee will work with a multi-disciplinary team of Argonne scientists spanning several divisions including XSD, Materials Science Division, Nuclear Science and Engineering Division, and Applied Materials Division.

In the last two decades, the APS has been a world leader in developing high-energy X-ray imaging techniques such as HEDM and High Energy Bragg Coherent Diffraction Imaging (HE-BCDI) to provide microstructure and micromechanical state information of polycrystalline materials at mesoscale and nanoscale, respectively. With the new High Energy X-ray Microscope (HEXM) beamline at 20-ID coming online as a part of the APS-U, we seek a postdoctoral researcher who will play a key role in further developing HE-BCDI and integrating it with HEDM. This integrated instrument at HEXM is envisioned to characterize polycrystalline materials and their hierarchical features spanning macroscopic to nanoscopic length scales. In particular, we are interested applying this novel instrument to understand the effect of irradiation on material strength and accumulation of damage.
