Swiss Light Source - SLS
COVID-19: SLS still in operation (5 days per week)
The SLS is in 'user operation without external users on site'. Remote-access by users and mail-in operation continues. For COVID-19 related research there is a special call -- please see below. The MX beamlines continue operation in 100% remote access mode -- please see below.
From June 5th onwards the SLS return to 24/7 operation with external users on site.
The Swiss Light Source (SLS) at the Paul Scherrer Institut is a third-generation synchrotron light source. With an energy of 2.4 GeV, it provides photon beams of high brightness for research in materials science, biology and chemistry.
SLS is part of the Photon Science Division. The facility has world-leading instruments at its beamlines for unraveling the structure of proteins, for in-depth 3D imaging of matter, and for investigating how the electrons of atoms and molecules keep matter together and render it properties such as magnetism and electron conduction at zero resistance (‘superconductivity’).
- The beamlines for protein structure determination are intensively used by pharmaceutical companies in Switzerland and abroad. SLS is also leading in the development of pixelated X-ray detectors. The company DECTRIS has been spun off from these activities.
- In something as complex as a human being structures and processes occur on all length scales from macroscopic down to atomic dimensions. The SLS host a variety of techniques to address problems on different length scales.
- Materials with new, functional properties are the scope of intense research, since they offer fascinating insights into fundamental interactions and hold promise for advanced technologies which is highly needed. The SLS host world-leading capability in advanced materials spectroscopy ranging from photoemission spectroscopy, over spectromicroscopy to different X-ray absorption, scattering and diffraction techniques.
- A further focus is to provide advanced micro- and nanofabrication technologies to academic and industrial users, in particular in the area of polymer nanotechnology.
Current operation status - reduced operation (5 days per week)
Latest Scientific Highlights and News
The Dikic group at the Goethe University in Frankfurt am Main, Germany has published the first results following the opening of the "PRIORITY COVID-19 Call” at SLS.
LaTiOxNy oxynitride thin films are employed to study the surface modifications at the solid- liquid interface that occur during photoelectrocatalytic water splitting. Neutron reflectometry and grazing incidence x-ray absorption spectroscopy were utilised to distinguish between the surface and bulk signals, with a surface sensitivity of 3 nm.
