The experimental endstation of the hard X‐ray beamline BL9 of the Dortmund Electron Accelerator is equipped with a Huber six‐circle diffractometer. It is dedicated to grazing‐incidence X‐ray diffraction and X‐ray reflectivity experiments on solid surfaces and thin films as well as to powder diffraction measurements. A new set‐up for grazing‐incidence X‐ray scattering of liquids has been built up using a silicon mirror to reflect the incident X‐ray to the liquid surface at angles of incidence around the critical angle of total reflection of the sample. X‐ray reflectivity measurements of a polymer film and grazing‐incidence X‐ray diffraction measurements of an epitaxically grown Gd 40 Y 60 film, an oxidized surface of Fe‐15at.%Al alloy and aqueous salt solutions are presented and discussed.
