“…This also allows the potential for SANS imaging using a twodimensional transmission monitor. Although a concept similar to ESANS has been presented previously (Petriw et al, 2010;Galvá n Josa et al, 2015), its analyses were insufficient for practical experiments, since the acceptance angle of the transmission monitor was not considered. Our analysis provides a quantitative explanation for the experimentally observed neutron attenuation spectrum and is demonstrated here for steel.…”

Recent progress of pulsed neutron sources has enabled energy‐resolved analysis of neutron attenuation spectra, which include information on neutron scattering. In this study, a new analysis technique for small‐angle neutron scattering (SANS) is demonstrated. A clear difference is observed in the neutron attenuation spectra between steels with different nanostructures; this difference can be understood as arising from attenuation due to SANS. The neutron attenuation spectra calculated from the corresponding SANS profiles agree well with the experimentally observed attenuation spectra. This result indicates that measurement of neutron attenuation spectra may enable the development of a novel experimental technique, i.e. energy‐resolved SANS.
