P09 Resonant Scattering and Diffraction beamline
P09 is designed to operate in the hard x-rays regime with energies ranging from 2.7 to 50 keV. The beamline consists of three experimental hutches. The first two experimental hutches, EH1 and EH2, are dedicated to resonant x-ray scattering and general diffraction (RSD) experiments. The third hutch, EH3, houses a Hard X-ray Photoelectron Spectroscopy (HAXPES) setup.
Experimental Hutch 1 is fully operational. It can be used for resonant X-ray scattering experiments to investigate magnetic order, orbital order or other processes giving rise to non zero intensity at otherwise forbidden positions in reciprocal space. In addition other scattering experiments requiring good energy tunability between 2.7 and 24 keV or variable polarization, like non-resonant magnetic scattering, can be performed. A phase retarder and a polarization analyzer are available in order to vary and analyze the polarisation of the incoming and scattered beam, respectively. Closed-cycle cryostats covering the temperature range between 1.7K and 800K are available. Complete windowless operation of the diffractometer is also possible.
Experimental hutch 2 is equipped with a heavy-load horizontal Psi-diffractometer. A 14 T split-coil cryomagnet working in the temperature range from 800 mK up to 300 K will become available in Summer 2012.
Experimental hutch 3 houses a Hard X-ray Photoemission experimental station. It is presently operational and can be used with the high heat load (111) or (311) monochromator, as well as with the phase retarder setup. Focusing at the sample position is achieved with the same mirrors used for focusing in EH1 and EH2.
