The small angle scattering beamline BW4 of HASYLAB: Recent developments and future perspectives — •Jan Perlich, Jan Rubeck, Stephan V. Roth, and Rainer Gehrke — HASYLAB-DESY, Notkestr. 85, D-22603 Hamburg (Germany)

The small angle scattering wiggler beamline BW4 of HASYLAB, Hamburg (Germany), is a dedicated materials science beamline. The main experimental techniques are transmission small angle X-ray scattering (SAXS) as well as grazing incidence small angle X-ray scattering (GISAXS) in reflection geometry. The implemented microfocus option at the BW4 instrument enables experiments where lateral scanning of sample materials is feasible. After major refurbishments of the beamline in the recent years, the focus is on expanding the experimental capabilities by the access to an extended scattering q-range, e.g. grazing incidence wide angle X-ray scattering (GIWAXS), and the introduction of necessary sample environments for the structural characterization of novel material systems at specific physical conditions. In addition, in-situ sample observations in transmission or reflection, i.e. dip-coating with GISAXS, are possible with a fast detector enabling the structural characterization of time-dependent processes. We present the novel experimental capabilities based on selected recent results and give an outlook on upcoming activities.
