Neutrons for the Industries of Manufacture and Energy, from Time-of-flight Small-angle Scattering and its Complementary Analyses

Abstract

We report the current advances of the iMATERIA instrument, i.e, time-of-flight small-angle neutron scattering (SANS), dedicated to observations on the manufactures and energy. The observations with multi-scale(from the minimum q_min = 0.001 Å^-1 to the maximum q = 30 Å^-1), the multi-time domains (> 0.5 sec) and the multi-contrast by dynamical nuclear polarization (DNP) are available. The multi-angle (or stereo) observation of the film specimen bridges the conventional SANS and reflectivity. For the multi-analysis, we developed the real time & simultaneous method by SANS and neutron radiography (NR), targeting the polymer electrolyte fuel cell. As our future plan, we propose to establish the simultaneous triple-analysis of SANS, NR and prompt γ-ray (PG) analysis. By scanning with a beam of 1mm²-size, we map structural parameters determined by SANS and elements determined by PG on the image by NR, as referred to the mapping image.
