P64 - Advanced X-Ray Absorption Spectroscopy

 

Planned start of user operation


The work on the beamline is making good progress. The commissioning with the first monochromatic beam in the experimental hutch started in April 2016 and continued until the start of the winter shutdown in December 2016. After the shutdown, the beamline will go into regular user operation. P64 is included in the next call for proposals. All optical components have been tested, and a few experiments in different fields with different set-ups have already executed.

Please contact the beamline scientist to check the availability of certain experimental equipment and the feasibility of your planned experiment before you submit your proposal!



P64 is dedicated to x-ray absorption spectroscopy experiments, which require high flux. Among those are quick EXAFS (QEXAFS) on the 20-100ms time-scale, EXAFS of highly-diluted systems, e.g. bio-molecules with an active metallic center, and high-resolution spectroscopy with a dispersive fluorescence spectrometer in von-Hamos geometry. Other experiments, which require special set-ups and which profit from the high flux and small, focused beam, are also feasible and can be discussed with beamline staff.

The monochromator saw the central cone of the undulator radiation for the first time by the end of May, and since then, alignment of the monochromator and mirrors has made some progress. Right now, the beamline is still in the commissioning phase.

Beamline P64 is located in the southern part of the newly erected PETRA III North Hall close to the FLASH 1 Hall.

X-Ray absorption spectroscopy finds applications in various research fields:
Physics: Mixed-valence compounds
Chemistry: Catalysis
Biology: Local environment of active metallic center
Environmental sciences: Fate and state of metallic contaminations
Arts: Composition and aging of paints
