Our mission

Prof. Dr. Christian Rüegg, division head NUM
NUM is the organisational home base for the research at PSI, which is based on the use of the PSI High Intensity Proton Accelerator HIPA and which spans the whole range from particle physics via solid, liquid or soft condensed matter science, chemistry, materials science and engineering to cultural heritage.

Among current topical scientific problems we specifically focus on those that are within the mission of PSI and optimally exploiting the state of the art instruments at our large scale facilities:
The Division is organised in five research laboratories:
  • LTP – the Laboratory for Particle Physics
  • LNS – the Laboratory for Neutron Scattering and Imaging
  • LMU – the Laboratory for Muon Spin Spectroscopy and
  • LDM – the Laboratory for Scientific Developments and Novel Materials
  • LMX – the Laboratory for Multiscale Materials Experiments

Furthermore there are three NUM staff groups:

The NUM division is responsible for operating SINQ and the Ultracold Neutron Source UCN, for the development of instrumentation at SINQ and SµS and for the testing materials and target technologies for proton accelerator driven systems. The facilities in the NUM division are open to international access - with 1700 annual visits the associated user program is a key activity in the division. The PSI User Office manages the large number of foreign visitors to all PSI facilities.
