The X-ray and neutron reflectometries have now widely used for the study of buried interfaces in thin films and multilayers. Neutron is an ideal probe for the reflectometry because of its transparency for the most of materials, and its sensitivity of light elements and magnetic moments in the materials. An intense pulsed neutron source (JSNS) is now under construction at Materials and Life Science Facility (MLF) as a part of J-PARC (Japan Proton Accelerator Research Complex) in Tokai-mura, Ibaraki prefecture, Japan. JSNS will provide the world highest intensity pulsed neutron for promoting materials science and life science in the beginning of the next spring. We have sent a letter of intent which proposed to construct a polarized neutron reflectometer at MLF to the director of J-PARC, and a preliminary examination has been passed. The outline design specification of this new polarized neutron reflectometer will be presented.
