Beamline 9

At the beamline Beamline 9 of DELTA we investigate different questions by means of the methods X-ray diffraction (XRD) and X-ray reflectivity (XRR).




  • superconducting wiggler 5 to 7 T
  • silicon (311) double crystal monochromator, first crystal water cooled and sagittal focusing second crystal
  • energy range 7 - 27 keV
  • energy resolution dE/E = 10-4
  • beam size at sample location: horizontally 1.5 to 0.5 mm2 and vertically 1.0 to 0.05 mm2 (depending on respective aperture)
  • typical photon flux 5 x109 photons/s/mm2 at 13 keV
  • silicon mirror
  • absorber and fastshutter system (XIA)
  • variable aperture system (JJ-xray)
  • control by SPECTRA software (implementation of SPEC commands available)


Experimental setups

  • 6-axis diffractometer (NaI point detector, Amptek, area detector MAR345, Pilatus 100K)
  • setup for small angle scattering (area detector MAR345)
  • setup for fast reflectivities and GID (Pilatus 100K)


  • diffraction, texture analysis
  • surface diffraction
  • reflectivity measurements
  • small angle scattering
  • fluorescence analysis

Sample environments

  • sample setup for in-situ heating of flat specimens and powders in capillaries up to 900°C
  • high pressure sample cell with copper sample element (1° to 80° and pressures up to 5 kbar)
  • nitrogen sample cooling (Cryostream 700, Oxford Cryosystems)
  • Anton Paar DHS1100 for in-situ diffraction (up to 1100°C)
  • Linkam HFSX350 temperature cell (-180 to 300°C)
  • cryostat
  • various sample cells for reflectivities and diffraction
  • sample rotation for powder diffraction
  • gas pressure cells up to 100 bar
  • sample cells for measurement of reflectivities at solid-liquid interfaces
  • vacuum environment (backing pump and turbopumps)
