Neutron Imaging and Engineering Diffraction
The Applied Materials Group (AMG) is a group within the Laboratory for Neutron Scattering and Imaging LNS, in the division research with Neutrons and Muons NUM of PSI. AMG 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. AMG also provides complementary x-ray imaging (in-situ bi-modal) and has dedicated beamtimes for imaging studies at the test beamline BOA providing an intense cold polarized neutron beam.
