Upgrade of the BW4 beamline at HASYLAB/DESY — •Stephan V. Roth, Ralph Döhrmann, Martin Dommach, and Rainer Gehrke — HASYLAB at DESY, Notkestr. 85, D-22603 Hamburg, Germany

Small-angle X-ray scattering is a versatile method to investigate mesoscopic correlations in bulk matter and thin films. The beamline BW4 is designed to extend this range to the ultra SAXS (USAX) regime [1,2]. Here, maximum resolvable length scales can be extended near 1µm upto several micrometers in grazing incidence geometry (GIUSAX) [3]. The scientic field ranges from deformation in polymer-based materials to thin film investigations in polymer and colloid science [2,4,3]. In an ongoing development program at HASYLAB the beamline BW4 has been refurbished. We will present the upgrade the BW4 beamline, including e.g. a dedicated SAXS position, the installation of new detectors and beam monitoring equipment. Furthermore we will focus on available sample environments like GISAXS cells, stretching and heating devices.
