The High Resolution Diffraction Beamline at PETRA III - First Experiments — •Carsten Deiter, Florian Bertram, Kathrin Pflaum, and Oliver H. Seeck — DESY, Notkestr. 85, 22607 Hamburg

Since 2009 the new synchrotron radiation source PETRA III is operational. At the High Resolution Diffraction Beamline (P08) the equipment and the beam parameters are highly suited for surface and interface studies. Different sample cells with heating and cooling capability and the possibility of vacuum and gas atmosphere up to 1bar are available. These cells can be installed in the six circle diffractometer (Kohzu) for extreme angular resolution and will be supported by an UHV infrastructure with MBE preperation, structural (LEED) and chemical (AES) analysis operational in late summer 2011. The first regular user experiments have been performed and some results will be presented which show the benefits of the PETRA III beam parameters.
