The quick EXAFS setup at beamline P64 at PETRA III for up to 200 spectra per second

. The layout and the characteristics of the Quick scanning EXAFS (QEXAFS, ref. [1]) setup at beamline P64 at the storage ring PETRA III, DESY, Germany are described. The quickly oscillating cryo-cooled monochromator allows measurements from 4.5 keV to 44 keV with frequencies up to 100 Hz. The effect of tapering of the undulator on spectra as well as the different detection schemes with transmission, reflectivity and fluorescence are discussed. The data acquisition is explained in detail. Reference spectra at different frequencies and examples of time resolved user experiments are shown. The influence of noise and filtering on the spectra is analysed.
