Abstract

Dark Field X-ray Microscopy (DFXM) is a full-field imaging technique for non-destructive 3D mapping of orientation and strain in crystalline elements. The new DFXM beamline at ID03, developed as part of the ESRF Phase II Upgrade Project (EBSL2), was designed to provide cutting-edge capabilities for studying embedded microstructures. The project relocated and upgraded the end station from ID06-HXM to ID03, integrating new X-ray optics, radiation hutches, and a source device optimized for this advanced technique. Notable improvements include a near-field camera, a new goniometer, and a high-resolution far-field camera. The conceptual design was completed in September 2019, followed by the technical design in March 2021, with first users welcomed in April 2024. Building on the success of the original instrument, the ID03 beamline offers enhanced multi-scale and multi-modal mapping of microstructures with high resolution, enabling in-situ exploration of complex phenomena. Applications range from strain and orientation mapping in metals to studies of functional materials, semiconductors, biominerals, and energy systems.
