The Paul Scherrer Institute runs Switzerland's Large research facilities for users from the national and international scientific community, in particular for condensed matter, materials science and biology research. PSI is one of only two locations in the world providing the three complementary probes of synchrotron X-rays, neutrons and muons at one site.
The institute's own research activities concentrate on scientific projects that strongly benefit from the use of the large-scale facilities. These cover a broad range of topics that can be grouped into three large fields: «Structure of Matter», «Energy and Environment» and «Human Health».
Each year, approximately 2000 scientists from all over the world visit PSI to perform their experiments, in fields such as condensed matter or fundamental physics, chemistry, biology or materials science. PSI is one of very few places in the world offering the three major probes for condensed matter research (synchrotron X-rays, neutrons and muons) on one campus.
The PSI User Office is a central PSI installation to serve the users from all the four user laboratories.
