P09 - Resonant Scattering and Diffraction Beamline

P09 is dedicated to resonant scattering and diffraction in the tender and hard x-ray range. The photon energy can be varied between 2.7 keV and 24 keV (EH1) or 32 keV (EH2). Beam sizes are between 4 µm and 1 mm. Complex sample environments allow for experiments as a function of temperature and high magnetic fields or high pressure or electric fields. The scattered polarization is analyzed by a polarization analyzer. Control of the incident polarization is possible between 2.7 and 13.7 keV. using phase retarder plates. Since 2019 beamline P09 offers X-ray magnetic circular dichroism as a probe and a 3rd hutch is open port allowing users to bring in own equipment for a beamtime.
