Swedish High-Energy Materials Science Beamline
The Swedish materials science beamline (P21) in the PETRA III Ada Yonath hall will operate in the energy range of 40 - 150 keV and accommodates a variety of diffraction, scattering, and imaging techniques making use of high X-ray energies. The inline branch is in particular designed for the combination of WAXS, SAXS, and Imaging techniques. Therefore the downstream "diffraction station" EH3 provides flexible positioning of various detector types including a SAXS camera 15 m behind the sample position. An interface diffractometer is optimized for grazing incidence geometries, and a diffractometer for bulk samples provides a vertical rotation axis with sub-micrometer concentricity. Both instruments can also support medium sized sample environments. The upstream "roll in" station EH2 is initially left free and offers the opportunity to accommodate (user supplied) larger sample environments.
The beamline side branch provides fixed photon energies of 52keV, 85keV, and 100keV with a beam size of about 1 x 1 mm², vertical focusing is optional. The experimental station EH1 will be equipped with a heavy load diffractometer, an optional Euler cradle, and point or area detectors. Applications will focus on high-energy x-ray diffraction on single crystals, amorphous materials, liquids and nanocrystalline matter, including PDF studies.
