SLS 2.0
L’upgrade de la Source de Lumière Suisse SLS
La Source de Lumière Suisse (SLS) est en service depuis 2001. Cette grande installation de recherche unique en Suisse a désormais été modernisée afin de rester à la pointe de la science, de la technologie, de l’ingénierie et du traitement des données. Avec SLS 2.0, les chercheurs peuvent réaliser des recherches innovantes et mener des analyses encore plus précises. Le financement de SLS 2.0 a été assuré dans le cadre du message FRI 2021–2024. La nouvelle SLS a été inaugurée le 21 août 2025.
