P08 - High Resolution Diffraction Beamline
P08 is specialized in X-ray scattering and diffraction experiments on solids and liquids where extreme high resolution in reciprocal space is required. The photon energy can be varied between 5.4 keV and 29.4 keV, the beamsize between 2 µm and 1 mm. The flux at the sample depends on the setup and is between 1010 and 1012 photons/sec. The resolution in reciprocal space at 8 keV corresponds to smallest lenghtscales of 80 pm with an accuracy of 5x10-5 and 5 µm for upper lengthscales. At 25 keV length scales between 30 pm with 10-4 accuracy and 1.5 µm are accessible.
