Resonant scattering and diffraction beamline P09 at PETRA III

The resonant scattering and diffraction beamline P09 at PETRA III is designed for X‐ray experiments requiring small beams, energy tunability, variable polarization and high photon flux. It is highly flexible in terms of beam size and offers full higher harmonic suppression. A state‐of‐the‐art double phase‐retarder set‐up provides variable linear or circular polarization. A high‐precision Psi‐diffractometer and a heavy‐load diffractometer in horizontal Psi‐geometry allow the accommodation of a wide variety of sample environments. A 14 T cryo‐magnet is available for scattering experiments in magnetic fields.
