  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 setup 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.
