PSI Center for Photon Science Mission

The PSI Center for Photon Science (CPS) operates two User Facilities, i.e. the Swiss Light Source (SLS) and the Swiss Hard X-ray Free Electron Laser (SwissFEL). Access for external users to the facilities is granted by scientific excellence through a peer review process. Research is performed by external users as well as by PSI scientists.

For construction and maintenance of the beamlines, the PSI Center for Photon Science (CPS) closely collaborates with groups from other divisions at the Paul Scherrer Institut. Researchers at the Laboratory for Micro- and Nanotechnology (LMN) are covering the broad spectrum of research activities from basic research in nanoscience over the development of new methods and instrumentation in collaboration with the PSI Center for Photon Science (CPS) laboratories.

The Photon Science Division consists of seven laboratories:


About 250 scientists and technicians, including approximately 55 postdocs and 30 PhD students build the team of the Photon Science Division.
