【 摘 要 】

The layout and the characteristics of the hard X-ray beamline BL 10 at the superconducting asymmetric wiggler at the 1.5 GeV Dortmund Electron Accelerator DELTA are described. Equipped with a stable and robust Si(111) channel-cut monochromator, this beamline is suited for XAFS studies in the spectral range from about 4 keV to ca. 16 keV photon energy. We will illustrate the performance of the beamline, and present EXAFS data obtained from several reference compounds. XANES data measured for dilute sample systems as well as surface sensitive grazing incidence EXAFS obtained from thin film samples will also be discussed.
