The applicability of an X-ray nanobeam generated using a 2-dimensionally confining waveguide is demonstrated for nanodiffraction purposes. The experiments were performed at the Nanofocus extension of MINAXS Beamline at PETRA III. The Nanofocus extension of MINAXS is designed to routinely provide a nanofocused X-ray beam for diffraction experiments and is operated by the University of Kiel. Next to an extensive characterization of the waveguide beam, first high resolution nanodiffraction experiments were performed, e.g. on nanocrystalline TiN hard coatings on WC-Co and on ZnO-microrods with a microscopic metallic coating. Using the high spatial resolution of the waveguide beam interfacial residual stress was revealed in both sample systems. Finally, this contribution presents the current status and future extensions of the Nanofocus endstation.
