The horizontal neutron reflectometer REFSANS allows to perform comprehensive analyses of vertical and lateral surface and interface structures by means of specular and off-specular neutron reflectivity as well as small-angle neutron scattering at grazing incidence (GISANS). All measurements can be performed on the air-water interface (horizontally aligned sample). The performance of this novel instrument is highlighted by means of recent measurements of weak off-specular scattering, GI-SANS and extremely low specular reflectivity including the case of a strong incoherent substrate scattering. This work has been supported by the German Federal Ministry of Education, Research and Technology (BMBF) under contracts 03-KA5FRM-1 and 03-KAE8X-3.
