The layout and the characteristics of the hard X-ray beamline BL10 at the superconducting asymmetric wiggler at the 1.5 GeV Dortmund Electron Accelerator DELTA are described. This beamline is equipped with a Si(111) channel-cut monochromator and is dedicated to X-ray studies in the spectral range from ∼4 keV to ∼16 keV photon energy. There are two different endstations available. While X-ray absorption studies in different detection modes (transmission, fluorescence, reflectivity) can be performed on a designated table, a six-axis kappa diffractometer is installed for X-ray scattering and reflectivity experiments. Different detector set-ups are integrated into the beamline control software, i.e. gas-filled ionization chambers, different photodiodes, as well as a Pilatus 2D-detector are permanently available. The performance of the beamline is illustrated by high-quality X-ray absorption spectra from several reference compounds. First applications include temperature-dependent EXAFS experiments from liquid-nitrogen temperature in a bath cryostat up to ∼660 K by using a dedicated furnace. Besides transmission measurements, fluorescence detection for dilute sample systems as well as surface-sensitive reflection-mode experiments are presented.
描述了位于1.5 GeV多特蒙德电子加速器DELTA的超导非对称摆动器上的硬X射线光束线BL10的布局和特性。该光束线配备了Si(111)通道切割单色仪，专门用于光子能量在约4 keV至约16 keV光谱范围内的X射线研究。有两个不同的终端站可供使用。在指定的工作台上可以进行不同检测模式（透射、荧光、反射率）下的X射线吸收研究，同时还安装了一台六轴卡帕衍射仪用于X射线散射和反射率实验。不同的探测器设置集成到了光束线控制软件中，即充气电离室、不同的光电二极管以及一台Pilatus二维探测器随时可用。通过几种参考化合物的高质量X射线吸收光谱展示了该光束线的性能。首次应用包括使用专用炉进行的从液氦温度到约660 K的变温扩展X射线吸收精细结构（EXAFS）实验。除了透射测量外，还展示了稀样品系统的荧光检测以及表面敏感反射模式实验。
