A new instrument for simultaneous microbeam small‐ and wide‐angle X‐ray scattering and X‐ray fluorescence (SAXS/WAXS/XRF) is presented. The instrument is installed at the microfocus beamline at BESSY II and provides a beam of 10 µm size with a flux of about 10 9 photons s −1 . A SAXS resolution up to 500 Å d ‐spacing and a range of scattering vectors of almost three orders of magnitude are reached by using a large‐area high‐resolution CCD‐based detector for simultaneous SAXS/WAXS. The instrument is particularly suited for scanning SAXS/WAXS/XRF experiments on hierarchically structured biological tissues. The necessary infrastructure, such as a cryo‐stream facility and an on‐site preparation laboratory for biological specimens, are available.
