The BAMline at the BESSY II synchrotron X-ray source has enabled research for more than 20 years in widely spread research fields such as materials science, biology, cultural heritage and medicine. As a nondestructive characterization method, synchrotron X-ray imaging, especially tomography, plays a particularly important role in structural characterization. A recent upgrade of key equipment of the BAMline widens its imaging capabilities: shorter scan acquisition times are now possible, in situ and operando studies can now be routinely performed, and different energy spectra can easily be set up. In fact, the upgraded double-multilayer monochromator brings full flexibility by yielding different energy spectra to optimize flux and energy resolution as desired. The upgraded detector (based on an sCMOS camera) also allows exploiting the higher flux with reduced readout times. Furthermore, an installed slip ring allows the sample stage to continuously rotate. The latter feature enables tomographic observation of processes occurring in the time scale of a few seconds.
BESSY II 同步加速器 X 射线源的 BAMline 已经在广泛的研究领域（如材料科学、生物学、文化遗产和医学）中开展了超过 20 年的研究。作为一种非破坏性的表征方法，同步加速器 X 射线成像，特别是层析成像，在结构表征中起着特别重要的作用。BAMline 关键设备的最近升级扩大了其成像能力：现在可以实现更短的扫描采集时间，现在可以常规进行原位和操作研究，并且可以轻松设置不同的能谱。实际上，升级后的双层多层单色仪通过提供不同的能谱来优化通量和能量分辨率，从而实现了完全的灵活性。升级后的探测器（基于 sCMOS 相机）还可以利用更高的通量并减少读出时间。此外，安装的滑环允许样品台连续旋转。后者的功能使在几秒钟的时间尺度内发生的过程的层析观察成为可能。
