The microfocus SAXS/WAXS beamline at PETRA III / DESY — •S.V. Roth, R. Döhrmann, H. Franz, R. Gehrke, U. Hahn, R. Röhlsberger, H. Schulte-Schrepping, N. Schwarz, and E. Weckert — HASYLAB at DESY, Notkestr. 85, D-22607 Hamburg, Germany

Among the first beamlines to be built at PETRA III is the microfocus small- and wide-angle x-ray scattering beamline µSAXS/WAXS. This beamline will exploit the excellent photon beam properties of the low emittance source PETRA III to provide micro- and nanofocused beams in dedicated end-stations with ultra-high intensity and resolution in real and reciprocal space. Targeting at scanning investigations at multiple length scales, the areas of research include in-situ experiments as well as brilliance demanding novel methods like microbeam grazing incidendence small-angle x-ray scattering (µGISAXS) [1] and microbeam SAXS tomography [2]. The current layout foresees a large-offset double crystal monochromator and compound refractive on-axis optics for microfocusing. The projected beam sizes for routine user operation range from 110nm-40µm. The design of the beamline especially allows for combining ultra small-angle x-ray scattering (USAXS) with a microfocused beam (µUSAXS). We will present the present layout of the µSAXS/WAXS beamline introducing the projected capabilities of this new micro- and nanofocus scattering beamline at PETRA III.
