This presentation introduces latest information of ultra-small-angle polarized neutron scattering equipment (SANS-J-II) at the guide hall of Japan research reactor No.3 (JRR-3) of Japan Atomic Energy Agency. SANS-J-II is used for a static or dynamic observation of hierarchical structure from micrometer to nanometer scale in a sample. Until now, various users have visited SANS-J-II for the purpose of industrial or academic research, concerning rubber materials for tires, polymer electrolyte membrane for fuel cell, microemulsion, gel, alloy, silicon single crystal including impurity, magnetic materials and so on. As recent topics, we newly introduced a large area detector composed of 96 one-dimensional position sensitive detectors (PSD) arranged in a plane. Furthermore, in 2011, we replaced Ni-coated neutron guide tubes with 3QC supermirror-coated ones, so neutron flux is expected to increase. We are planning to verify the improved performance after the restart of JRR-3.
