Materials science and reverse bioengineering - Status and potential Applications of the nanofocus endstation of µSAXS-beamline at Petra III — •Christina Krywka1, Stephan Roth2, and Martin Müller3 — 1Christian-Albrechts-Universität zu Kiel, Institut für Experimentelle und Angewandte Physik, Leibnizstraße 19, D-24098 Kiel — 2DESY, Notkestraße 85, D-22063 Hamburg — 3GKSS Forschungszentrum Geesthacht, Max-Planck-Straße 1, D-21502 Geesthacht
The new synchrotron Petra III is going be a high-brillance synchrotron radiation source, located on the site of DESY in Hamburg, Germany. For this purpose, the existing Petra storage ring is being refurbished into one of the most brillant x-ray sources worldwide and its completion is scheduled for 2009. The µSAXS-beamline of Petra III will be equipped with an additional endstation, designated to provide a high flux x-ray beam focused to about 100nm × 100nm. At the nanofocus endstation experiments with a superior spatial resolution will become available with a flux sufficiently high to study both biological and synthetic materials. This contribution presents an overview on the beamline extension and the current status of its completion. Also, exemplary and potential applications of nanofocused x-rays are shown. Among these are diffraction methods used for the structure determination of synthetic materials (e.g. metallurgy, surface science, semiconductor technology) and biological materials with multiple levels of structural hierarchy (e.g. wood, fibres, cells).
