Abstract

The cold neutron tomography station operated at SINQ (Paul Scherrer Institute, Switzerland) is reviewed. The high neutron flux together with a set-up based on a scintillator screen and a CCD camera yielded fast and effective results with resolution down to 250 μm: tomography of small samples (up to 2 cm large) could be performed in less than an hour. The use of a velocity selector improved the contrast discrimination and allows dichromatic tomography. The station is moving to the new research reactor FRM-II (Garching, Germany) where its performances will be increased by the availability of a 5-times-higher cold neutron flux.
