Research with Neutrons and Muons (NUM)

The NUM division performs world-class research with neutrons and muons to explore and understand matter and materials. The NUM division operates and develops the Swiss Spallation Neutron Source SINQ, the Ultra-cold Neutron Source UCN, the Swiss Muon Source SμS and the facilities for particle physics at the Paul Scherrer Institute and is one of the five PSI research divisions.
