Highlights de SOLEIL 2017

Partager

2017 restera l’année au cours de laquelle, pour la première fois, la totalité des 29 lignes de lumière de SOLEIL a reçu des photons. Le nombre de stations expérimentales opérationnelles a continué à augmenter, avec l’ouverture aux utilisateurs de la branche d’imagerie multi-échelle par fluorescence X à résolution submicroscopique sur NANOSCOPIUM, et les premiers tests de micro- et nanotomographie X sur ANATOMIX…
 
Feuilletez la version électronique de ce recueil reprenant une sélection des résultats scientifiques marquants obtenus à SOLEIL en 2017.
