Abstract
High-resolution neutron counting sensors with microchannel plates coupled to a Timepix readout enable high spatial (similar to 55 mu m) and temporal (similar to 1 mu s) accuracy for each detected thermal and cold neutron. One of the attractive applications for those sensors is the high-resolution strain mapping in engineering samples through transmission Bragg edge diffraction. The unique combination of high detection efficiency (up to 70%), high spatial and temporal resolution of, detectors enable similar to 100 mu m strain mapping with similar to 100 mu strain accuracy. We present the results of proof of principle measurements performed at ROTAX beamline at ISIS spallation neutron source. Strain map of a bent steel sample is measured... (More)

We present the results of proof of principle measurements performed at ROTAX beamline at ISIS spallation neutron source. Strain map of a bent steel sample is measured with very high spatial resolution. The same sensors enable high-resolution nondestructive studies in such diverse areas as neutron microtomography, dynamics of fuel injection, material composition, archaeology, water propagation and many others.
