| Abstract Scope |
High-energy x-rays from 3rd generation synchrotron sources, including the Advanced Photon Source (APS), possess a unique combination of high penetration power and spatial, reciprocal space, and temporal resolution. These characteristics, coupled with extensive worldwide efforts over the past decades, have produced a variety of 3D imaging techniques using both density and diffraction/scattering contrast. These techniques operate in air with large working distances between optics, samples and detectors. This has enabled development and use of a variety of in-situ environments, with an overarching goal to best simulate the (often extreme) service conditions of materials. I will describe several of these environments, including thermo-mechanical loading systems and additive manufacturing platforms, while highlighting some key scientific results – particularly in the area of structural materials. Future developments will also be discussed in the context of the upcoming APS upgrade to a diffraction-limited source. |
