XAFS50.FR
50 Years of XAFS Adventure in France: From the Pioneers of LURE to 4th-Generation Sources
The XAFS50.FR conference will take place at SOLEIL from October 5 to 9, 2026.
How can we observe the environment around atoms ? Over the past 50 years, XAFS (X-ray Absorption Fine Structure) spectroscopy has attracted researchers from every field thanks to its atomic and orbital selectivity combined with high sensitivity, offering unique access to the structural and electronic properties of materials.
Developed in parallel with major advances in synchrotron radiation, XAFS has established itself step by step, becoming an essential tool for many scientific communities as well as for industry, and is now even beginning to appear as a laboratory-based technique with commercial spectrometers.
The XAFS50.FR event will bring together historical insight and scientific perspectives, highlighting the pioneering experiments carried out at LURE (ACO, DCI, Super-ACO), the development of formalisms and the standardization of analyses, and the current progress at SOLEIL and the 4th generation source ESRF-EBS — a development that SOLEIL-II will soon join.
