SLS 2.0
The upgrade of the Swiss Light Source SLS
The Swiss Light Source SLS has been in operation since 2001. Now this large research facility, unique in Switzerland, is getting an upgrade. Because science, technology, engineering, and data processing have advanced. After the modernisation project, called SLS 2.0, novel research and more precise investigations will be possible at SLS. With this technical overhaul, SLS remains in the top tier in comparison with other synchrotron light sources internationally. Funding for the project is provided within the framework of the ERI Dispatch 2021-2024.
