A new neutron reflectometer SuperADAM has recently been built and commissioned at the Institut Laue-Langevin, Grenoble, France. It replaces previous ADAM. The instrument uses a solid state polarizer/wavelength filter providing highly polarized (up to 98.6%) monochromatic flux of 8 × 104 n cm−2 s−1 with monochromatization Δλ/λ = 0.7% angular divergence Δα 0.2 mrad. includes both single position sensitive detectors. detector allows simultaneous measurement specular reflection off-specular scattering. Polarization analysis for scattering is achieved using either mirror analyzers or 3He spin cell. High efficiency detectors, low background, high provides dynamic range up seven decades in reflectivity. Detailed specifications capabilities are illustrated examples collected data fields thin film magnetism polymer films.
