PSI develops, builds and operates complex large research facilities. PSI has the world's most powerful muon source, a unique proton and neutron source, an synchrotron of international importance and one of only five X-ray free-electron lasers with hard X-rays in the world. Scientists from all over the world use PSI's large research facilities for their scientific investigations. They are also available to Swiss research and industry for their experiments.
