柏林 BESSY 光源的 BAMline 和卡尔斯鲁厄 ANKA 同步加速器设施的 TopoTomo 光束线（均为德国）在硬 X 射线区域（高于 6 keV）下运行，具有相似的光子通量密度。对于典型的成像应用，使用双层单色仪或过滤的白光束。为了优化可用间接像素探测器的视场和分辨率，安装了不同的光学系统，分别适应大视场（宏观）和高空间分辨率（显微镜）。它们可以与不同的相机系统结合使用，从 16 位动态范围慢扫描 CCD 到快速 CMOS 相机。通过使用布拉格放大器，空间分辨率可以大大超出微米极限。与其他第三代光源相比，两条光束线的中等通量通过专用闪烁体概念进行补偿。对于选定的应用，X 射线束准直已被证明是增加可用光子通量密度的可靠方法。根据应用使用吸收衬度、相位衬度、全息摄影和折射增强成像。此外，在 TopoTomo 光束线，使用安装的数字 X 射线像素探测器进行数字白束同步加速器形貌分析。
The BAMline at the BESSY light source in Berlin and the TopoTomo beamline at the ANKA synchrotron facility in Karlsruhe (both Germany) operate in the hard X-ray regime (above 6 keV) with similiar photon flux density. For typical imaging applications, a double multilayer monochromator or a filtered white beam is used. In order to optimise the field of view and the resolution of the available indirect pixel detectors, different optical systems have been installed, adapted, respectively, to a large field of view (macroscope) and to high spatial resolution (microscope). They can be combined with different camera systems, ranging from 16-bit dynamic range slow-scan CCDs to fast CMOS cameras. The spatial resolution can be brought substantially beyond the micrometer limit by using a Bragg magnifier. The moderate flux of both beamlines compared to other 3rd generation light sources is compensated by a dedicated scintillator concept. For selected applications, X-ray beam collimation has proven to be a reliable approach to increase the available photon flux density. Absorption contrast, phase contrast, holotomography and refraction-enhanced imaging are used depending on the application. Additionally, at the TopoTomo beamline digital white beam synchrotron topography is performed, using the digital X-ray pixel detectors installed.
