NIAG - Neutron Imaging and Activation Group

NIAG is a group within the Laboratory for Neutron Scattering and Imaging LNS , in the division research with Neutrons and Muons NUM of PSI. NIAG is operating 2 dedicated neutron imaging facilities and the neutron strain scanner (diffractometer) POLDI for users from scientific institutions and industry. Neutron radiography is complementary to X-ray radiography due to differences in radiation matter interaction. Neutrons interact with the atomic nucleus, whereas X-rays as electromagnetic radiation rather interact with the electrons. For strain scanning this also enables access deep into the bulk of engineering materials and geological samples. NIAG also provides complementary x-ray imaging (in-situ bi-modal) and has dedicated beamtimes for imaging studies at the testbeamline BOA providing an intense cold polarized neutron beam.
Imaging Facilities
NEUTRA Radiography / tomography with thermal Maxwellian spectrum Optional 320kV X-ray tube, NEURAP setup for highly activated samples.
ICON Radiography / tomography with cold neutron spectrum Micro-tomography, Energy selective imaging, Grating interferometry.
Strain Scanning Diffractometer
POLDI Strain Scanning TOF diffraction with multiple pulse overlap.
Neutron activation experiments in two dedicated facilities are performed by the Laboratory for Radiochemistry (LRC), for which NIAG acts as the contact point to NUM, which is operating the neutron source.
NIS Neutron irradiation services Neutron activation / Isotope production
