A 4-day summit of talks, posters, activities, and discussion 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. The first workshop on Frontiers in Science at 4th generation synchrotron facilities, to be held October 12th & 13th, 2026 at SOLEIL. Its scientific scope is intentionally broad and includes the SOLEIL scientific challenges defined in the Conceptual Design Report and discussed in the science sections of SOLEIL. The workshop aims to address important science topicsand major scientific and societal challenges that could benefit from the future evolution of synchrotron facilities, gathering the community to exchange ideas and share breakthroughs. Invited talks from international leaders will review key scientific questions and discuss the associated research needs, including new capabilities in instrumentation, techniques, data analysis, and facility capacity with emphasis in imaging and coherence-based techniques. An additional goal is the complementarity with other large-scale facilities (such as TEMs, lasers, FELs, etc.). The 10th edition of the ‘Crystallography and Large Scale Facilities’ school will take place at the SOLEIL synchrotron site in Saint-Aubin from 2 to 6 November 2026. The main objectives of this thematic school are to enable participants to reconnect with the fundamentals of crystallography: acquiring the theoretical foundations of crystallography and its methods, and using software for the determination and refinement of crystal structures. All disciplinary fields utilising crystallography are covered. It provides a state-of-the-art overview of the possibilities offered by various experimental methods and, in particular, at large scale facilities (i.e. synchrotron, neutron and XFEL sources). At Master’s level, it is aimed at PhD students, postdoctoral researchers, engineers, lecturer-researchers and researchers, as well as current or potential users of major research facilities. This five-day course comprises lectures, tutorials and practical sessions. It enables participants to quickly engage with applications and to link the training directly to their research work. The course also fosters close interaction with lecturers from major French laboratories specialising in crystallography and experts in their fields, and facilitates exchanges with participants from various disciplines. The course, accommodation and meals will be provided at the SOLEIL synchrotron site. The language of instruction is English and places are limited to 27. The Quantum Hackathon – SESAME 2026 that will be taking place at SESAME from 5-7 November 2026.
