Découvrez dans ce document une sélection des résultats remarquables obtenus par nos utilisateurs et nos équipes. Ils nous permettent de rester optimistes pour l’avenir, malgré un contexte difficile lié aux conséquences de l'invasion de l'Ukraine par la Russie, qui nous a conduit à nous adapter en prenant différentes mesures visant à réaliser des économies d’électricité. Ces mesures n'ont cependant pas eu d'impact immédiat sur les recherches menées à SOLEIL, comme en attestent le nombre de projets acceptés par les comités de programme et le nombre d’expériences menées sur nos lignes de lumière.
