The Paul Scherrer Institute operates four major user laboratories: a third generation X-ray synchrotron source (SLS), the only continuous spallation neutron source worldwide (SINQ), the worlds most powerful continuous-beam μSR facility (SμS) and a meson factory for fundamental nuclear and elementary particle physics (LTP). In fact, PSI is one of the very few places worldwide to offer 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. In case of any question before, during or after your stay at PSI please don't hesitate to contact us.

The central tool to organize the user operation at PSI is called the Digital User Office DUO. This is a Web application to submit proposals, experimental reports, publications, to request for PSI badges or dosimeters, register for conferences etc.
