  <p>The beamline P64 is located in the north of the PETRA III storage ring. It is dedicated to X-ray absorption spectroscopy experiments with high flux and high photon energy. Regular user operation started on May 5, 2017. Experiments cover wide ranges of research like: solid state physics, catalysis, bio-chemistry, environmental sciences etc.<p>The poster-presentation will concentrate on the two main projects in 2017:
- von-Hamos Spectrometer for X-Ray Fluorescence Spectroscopy
- Liquid Sample Cell<p>In 2017, a new von-Hamos-type X-ray emission spectrometer was constructed and installed at the beamline P64. It is dedicated to work in a 90° geometry for pure fluorescence mode. It comprises, inter alia, a fine-tunable array of cylindrical Bragg crystals, a rail-positioning system for fast detector-alignment and two CMOS-based X-Ray area detectors (LAMBDA-detector).<p>Another development is the construction of a liquid flow cell, which can be used for fluorescence and for absorption spectroscopy. It is used for experiments (as an alternative to the liquid jet), where only small amounts of liquid samples are available or where liquids should be protected from oxygen atmosphere.
