P21 Swedish Materials Science Beamline

The Swedish Materials Science beamline (SMS) is dedicated to materials research using high-energy x-rays. The beamline consists of an inline branch (P21.2) and a side branch (P21.1), which are operated in parallel and are optimized for a combination of techniques (WAXS, SAXS, imaging) and broad band diffraction, respectively.

The inline branch 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 monochromatic beams can be combined with various point and line focusing options. 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 may also be used as multi-purpose instrument. A diffractometer for bulk samples provides a vertical rotation axis with sub-micrometer concentricity is under design. Both instruments can also 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.

The side branch operates with a fixed angle of a single-bounce (broad band) monochromator providing photon energies of 52 keV, 85 keV, and 100 keV. In the experimental hutch EH1 a set-up for high-energy x-ray diffraction is utilized for studies of single crystals, amorphous materials liquids and nanocrystalline matter. It comprises a heavy load sample stage and a detector stage with both point and area detectors.

Academic hosting of the SMS beamline is provided by the Royal Institute of Technology (KTH) and Linköping University (LiU) through the Center for X-rays in Swedish Materials Science (CeXS).

The SMS beamline is open for user proposals upon the regular Call for Proposals. For detailed information on the application procedure and the administrative preparation of your experiment please consult our User Guide. Proposals with a leader from a swedish institute should select “Sweden-DESY collaboration” under “User Group/Collaboration” (for proposals at any DESY beamline).

Users are strongly advised to contact the SMS beamline staff to discuss the feasibility of the planned experiments before submitting a proposal.
