Methodical Progress in Neutron Imaging at PSI

Publication date: 2017 Source:Physics Procedia, Volume 88 Author(s): E. Lehmann, M. Raventos, R.P. Harti, P. Trtik, A. Kaestner, D. Mannes, C. Grünzweig Within this paper we summarize new approaches for the utilization of neutron beams for imaging purposes. Whereas most of the methods are still based on the radiography mode - however now with higher performance with respect to spatial resolution, dynamic range and linearity (obtained often in short exposure time) - the new aspects of using polarized neutrons, the diffracted neutron signal or grating interferometers are linking towards neutron scattering investigations. Many of the new techniques have already found their user community, while some of them are based on users demands themselves. The further progress in the field depends much on the access to useful beam ports at suitable neutron sources.
