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.

A hand like no other

Matter and Material Research Using Neutrons

A 3,500-year-old bronze sculpture is being examined at PSI's SINQ neutron source. This will enable conservators to get a unique view into the interior of the sensational find – and gain insights into how it was made.

Visualising strong magnetic fields with neutrons

Media Releases Matter and Material Materials Research Research Using Neutrons

For the first time, PSI researchers have used neutrons to visualise very strong magnetic fields that are up to one million times stronger than Earth's magnetic field. This now makes it possible to study magnets that are already installed in devices such as magnetic resonance tomography systems or alternators.

LIN builds pressure vessels for joint detector project with FRM-II in Munich

Highly efficient two-dimensional detectors are essential for the performance of modern neutron diffractometers. The NUM Division of PSI and the Technical University Munich TUM jointly develop two identical new ³He gas detectors, one for the diffractometer DMC at SINQ and the other for operation at FRM-II in Munich.

PSI participates in ECNS in St Petersburg

The European Conference on Neutron Scattering (ECNS) with its recent 2019 edition in St. Petersburg is a spree of lectures, poster sessions, and expert talks on the current trends and future possibilities in neutron science. PSI with its neutron source SINQ was represented by members of the three NUM laboratories LNS, LMX and LIN. In addition, PSI was silver sponsor of ECNS 2019 and is also a member of the LENS consortium (League of Advanced European Neutron Sources).
