SOLEIL’s contribution to understanding Astrophysics & Astrochemistry

More than 10 years after the opening to our users, SOLEIL takes stock of the important results obtained thanks to the beamlines during this period. Thus, we invite you to discover a series of thematic brochures presenting the major scientific contributions of Synchrotron SOLEIL to several society challenges. After the Medical Diagnosis and Prognosis, the Agro-Food sector and...
