We report on an experimental setup installed at the SAW2 (Superconducting Asymmetric Wiggler) beamline of the Dortmund Electron Accelerator DELTA that allows grazing incidence small angle scattering (GISAXS) experiments on liquid surfaces. GISAXS is a unique technique to probe surface and near-surface structures of soft materials. The setup was designed for photon energies between 8 and 15keV using a six circle diffractometer in combination with a focussing mirror. First GID experiments have already been succesfully performed on water and aqueous NaJ solution as well as on polypropylenglycol (PPG) samples.
