P21.2 - Swedish Materials Science Beamline: Diffraction & Imaging

The inline branch of the Swedish materials science beamline operates in the energy range of 40 - 150 keV and is in particular designed for the combination of WAXS, SAXS, and Imaging techniques. Broad and narrow bandwidth beams are provided with various point- and line-focusing combinations. The beamline has been available for user experiments since August 2019.

The "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,but is presently also used for bulk samples. A second diffractometer for bulk samples is under design. Both instruments can support medium sized sample environments (up to a weight of few hundred kg). Larger sample environments can be operated in the upstream "roll in" station EH2 which, however, is not instrumented yet.
