P10 - Coherence Application Beamline

The Coherence Beamline P10 at PETRA III benefits from the outstanding brilliance of the new storage ring. The flux of coherent synchrotron radiation exceeds that delivered by existing storage ring based sources. The beamline operates in the medium-hard x-ray regime (5-25keV). The beamline serves two main experimental goals: Investigation of sample dynamics in the range from microseconds to seconds by X-ray Photon Correlation Spectroscopy (XPCS) and Coherent imaging of micro- and nanostructures.
