We want to investigate the flow dynamics of two comparable wormlike micellar surfactant solutions that show special shear-induced features. Previous small-angle light and neutron scattering experiments on such systems showed that the most valuable structural information are given in the U-SANS-regime, from which we stayed out of range so far.Rheo-SANS experiments on D11, with lowest momentum transfer and lowest background possible should fill this gap and help elucidating the meso- and small-length scales, where these unique sample-properties are caused. For the foreseen time-triggered rheo-SANS experiment a rheometer with couette-setup and an inhouse development for the technical linkage (rheometer- and SANS-instrument) will be provided by ETH.
