Polarized neutron reflectometer SUIREN at JRR-3

Recent status of the neutron reflectometer SUIREN is presented. Since its startup in 2006, SUIREN has been the only neutron reflectometer in Japan for magnetic samples with high magnetic field sample environment, and used for investigations of magnetic films, solid-liquid interfaces and other solid thin films. SUIREN provides monochromatic neutron beam of 3.93 Å for vertically placed sample surface. Polarized beam is also available together with a 1 T electromagnet for sample. Beam intensity at the sample position in the unpolarized mode is 18000c/cm2/s for beam collimation of Δθ=0.08∘Δθ=0.08∘. Reflectivity can be explored down to 10-610-6.
