Advancing 4D Imaging: Pink Beam DFXM and 3DXRD at ESRF's ID03

In the past seven years, the PI, in collaboration with ID06-HXM staff and the DTU, has led advancements in DFXM achieving 100 nm resolution in 3D imaging of crystalline materials. Despite its success, DFXM needs significant improvements for mapping deformation and grain interaction. This LTP, part of an ERC-funded project, aims to enhance DFXM into a faster, real-time 3D imaging platform. Utilizing ID03's pink beam and optimized goniometer, we expect a 100-fold speed increase, enabling detailed in-situ studies. The LTP focuses on developing pink beam DFXM for better time resolution, implementing topo-tomographic DFXM and integrating 3DXRD with DFXM for multiscale analysis. These advancements will deepen our understanding of deformation and recrystallization at the grain level, leading to the development of materials with superior properties. Supported by ERC, this LTP fosters represents a significant step in validating 3D material models and understanding complex structures.
