X-ray techniques comprise a range of experimental methods that exploit the interaction of X-ray photons with matter to probe structural, electronic, and compositional properties across length scales from atomic to macroscopic. Major classes include X-ray diffraction (single-crystal, powder, and small- or wide-angle scattering) for determining crystallographic and nanoscale structure; X-ray spectroscopy (XANES, EXAFS, XPS) for probing oxidation states, local coordination, and electronic structure; and X-ray imaging and tomography for spatially resolved density and phase-contrast mapping. These techniques rely on well-characterized X-ray sources, monochromators, detectors, and often synchrotron or free-electron laser facilities to achieve high brilliance, energy tunability, temporal resolution, and quantitative analysis.
With the declared aim of measuring matter under extreme pressure, an international research collaboration headed by the University of Rostock and the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) used the high-performance laser ...
