Profile PETRA_2015_with Extensions

DESY operates one of the world’s brightest storage-ring-based X-ray radiation sources: PETRA III offers outstanding opportunities for scientific user experiments since 2009. Based on this, the present beamline portfolio encompasses key instrumental and methodological capabilities that enable high-resolution diffraction and inelastic spectroscopy, correlation spectroscopy and imaging with coherent X-rays, or high-resolution X-ray microscopy and nano-analysis. The high brilliance particularly benefits researchers investigating very small samples or requiring tightly collimated and very short-wavelength X-rays for their experiments, like for the instance investigations of solar cells, catalysts, and batteries under working conditions.

  • Energy range from ~150 eV to 200 keV ; brilliance exceeding 1021 ph/(s mm2 mrad2 0.1% BW).
  • Together with the free-electron laser FLASH at DESY, PETRA III welcomes experiments in the fields of physics, biology, chemistry and crystallography, materials and geological sciences as well as medical applications.
