本文介绍了1.5GeV多特蒙德电子加速器DELTA超导非对称扭摆器中硬X射线束线BL 10的布局和特性。该光束线配备有Si（111）通道切割单色仪，并致力于在光谱范围内的X射线研究，从类似于4 keV到类似于16 keV的光子能量。有两种不同的终端站可用。虽然可以在指定的工作台上进行不同检测模式（透射、荧光、反射）下的X射线吸收研究，但安装了一台六轴kappa衍射仪进行X射线散射和反射率实验。不同的检测器设置集成到光束线控制软件中，即充气电离室、不同的光电二极管以及Pilatus 2D检测器都是永久可用的。光束线的性能说明了高品质的X射线吸收光谱从几个参考化合物。第一个应用程序包括温度依赖EXAFS实验从液氮温度在浴低温恒温器到类似于660 K通过使用专用炉。除了传输测量，荧光检测稀释样品系统，以及表面敏感的反射模式实验。
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 similar to 4 keV to similar 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 similar 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.
