Micro- and nanofocused x-ray beams combined with small- and wide-angle x-ray scattering (SAXS/WAXS) are powerful tools to investigate nanocomposite and hierarchical materials on multiple length scales. In 2009, the microfocusSAXS/WAXS beamline P03 will become operational at PETRA III. This beamline 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. Strong emphasis is put on the future improvements of the various experimental IN-SITU scanning techniques, such as nano- and microbeam GISAXS [1,2] and micro/nanoSAXS tomography [3] as well as its possible combinations with high-througput and industrial processing methods for thin film technology and fluidics.
