The x-ray diffraction instrument at the HASYLAB high-energy wiggler beamline BW5 in Hamburg was set-up for diffraction experiments with wavelengths in the range of 0.1Angstrom. It can be particularly configurated for texture and/or other microstructure investigations in polycrystalline materials of any kind. The performance of the whole equipment was checked with random samples on the one hand and monocrystals on the other as well as for various textured materials. A software system leading from the experimental diffraction data to pole figures and to ODF, particularly designed to the specifications of BW5, was developed and installed. The experimental set up and the software system for quantitative texture analysis are available for external users.
