Highlights de SOLEIL 2019

L’année 2019 a été marquée par le début du travail sur un avant-projet sommaire dans le but de préparer la jouvence des installations de SOLEIL, suite à la demande de son Conseil en décembre 2018. Travail réalisé en parallèle des expériences qui continuent à être menées sur les –désormais– 29 lignes de lumière du synchrotron, et dont nous vous proposons une sélection des résultats les plus marquants publiés en 2019.
