The potential of the horizontal ToF-neutron reflectometer REFSANS at FRM-II Munich highlighted by recent experimental results

摘要: 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.
