DELTA is a small synchrotron in Dortmund performing at 1.5 Gev and a maximum current of 130 mA. After the commissioning of the beamline BL 10 was finished in August 2012 it is now open for all users. The beamline is devoted to materials science research with the focus on X-ray diffraction and absorption spectroscopy measurements. Possible experiments are precise single crystal diffraction, charge density studies and also fatigue studies in metals, transmission and fluorescence EXAFS measurements and reflection mode EXAFS. The beamline is working at an energy range of 4.5 to 16 keV with an energy resolution of dE/E ∝ 1.6 · 10−4. Depending on the aperture it is possible to measure with a beamsize between 3 · 10 mm2 and 0.5 · 0.1 mm2. The photon flux is with a focusing mirror expected to be 5 · 109 Photons /s mm2. The user can decide between several detectors, a Pilatus 100K 2D, a Scintilation Counter, an Avalanche Photodiode or Ionization Chambers. First diffraction measurements with Quartz powder obtained with the 2D and point detectors show that high-quality powder diffraction measurements are possible at the beamline. And the diffraction of a BSO single crystal shows that the intensity is comparable to the now closed beamline D3 at Doris. So we close a gap for all users who do not get beamtime at big synchrotrons.
