Neutron reflectometry and SANS, NSE and grazing incidence

The depth profile of macroscopic layer structures is made visible using neutron reflectometry. In the area of soft matter research, H/D contrast variations are again an important tool to increase the information content of a measurement. Lateral structures become visible in the diffused scattering in addition to offspecular scattering. This is used with SANS and NSE with a grazing incidence (GISANS, GINSE).

A special new method to increase intensity while using GINSE involves the use of multi-layered substrates, so that the coating of a resonator, where the amplitude of the evanescent matter wave of the totally reflected neutron beam (where the layer to be studied is positioned), is increased by more than one order of magnitude.
