Small-angle neutron scattering (SANS) technique has been indispensable in research of microstructures and hierarchical structures in materials science and life science. However, recent progress in nanotechnology and research of complex multi-component or multi-phase systems and non-equilibrium systems has required the SANS technique to enable to produce structural information more efficiently with higher structural and time resolution. The time-of-flight SANS instrument HI-SANS constructed at the 1MW neutron source of J-PARC has potential to satisfy such requirements by simultaneous coverage of wide q-range with high q-resolution by using large area detectors located at positions with short total flight path of neutrons and with polarizing and magnetic focusing devices.
