The microSAXS/WAXS beamline at PETRA III — •Stephan V. Roth, Ralph Döhrmann, Rainer Gehrke, Ulrich Hahn, Horst Schulte-Schrepping, Michael Lohmann, Heinz Graafsma, Ralf Röhlsberger, Hermann Franz, and Edgar Weckert — HASYLAB at DESY, Notkestr. 85, D-22607 Hamburg, Germany

Due to its outstanding brilliance, the third generation synchrotron radiation (SR) source PETRA III at DESY, being currently under construction, offers ideal conditions for combining micro- and nanofocused x-ray beams with small- and wide-angle x-ray scattering (SAXS/WAXS). From mid 2009 on, the microfocusSAXS/WAXS beamline P03 will be operational at PETRA III. The beamline layout combines high resolution in both real and reciprocal space with beam sizes ranging from 40µm to 100nm. The low divergence offered by the high-β undulator allows for installing ultraSAXS geometries in combination with such small beams. We present the detailed layout of the µSAXS/WAXS beamline [1]. Strong emphasis is put on the future improvements of the various experimental scanning techniques, such as nano- and microbeam GISAXS [2], nanoWAXS [3] and micro/nanoSAXS tomography [4].
