The novel beamline P03 (Micro- and Nanofocus X-ray Scattering, MiNaXS) at PETRA III serves a nano- and microfocus end station for performing small- and wide-angle x-ray scattering (SAXS/WAXS) experiments. With its microfocus end station being now in full user operation, its versatility allows for incorporating advanced complementary methods, such as fluidics and imaging ellipsometry [1]. To highlight the unique research capabilities at MiNaXS in terms of microfocused x-ray beams, low divergence and time-resolution, we present the results of in-situ spray and high-rate sputter deposition. The combination of high local and temporal resolution enables the in-situ observation of the fast deposition and nanostructure build-up in combination with microbeam grazing incidence small-angle x-ray scattering (µGISAXS): The nanostructure build-up is locally analyzed from the initial deposition stages to the late vertical nanostructure and domain build-up with ms time resolution.
