摘要

报告介绍了一种多光束 X 射线断层摄影光学系统的设计和评估实验，该系统可用于能量带宽较窄的同步辐射源（即衰减器辐射源）。该系统由硅单晶组成，可将入射的 X 射线衍射成 27 束光束，用于对样品成像。这些光束的能量被精确对准，足以在典型的衰减器光束线中使用。测试样品的投影图像已被采集并成功重建，这表明基于该光学系统的高速 X 射线断层成像仪是可行的。

Multibeam X-ray tomography optical system for narrow-energy-bandwidth synchrotron radiation

The design and evaluation experiments of a multibeam X-ray tomography optical system that can be used with synchrotron radiation from sources with a narrow energy bandwidth, i.e. undulator sources, are reported. It consists of silicon single crystals that diffract the incident X-rays to 27 beams, which are used to image a sample. The energy of the beams was aligned with an accuracy sufficient for use at typical undulator beamlines. Projection images of a test sample were collected and successfully reconstructed, showing the feasibility of a high-speed X-ray tomography instrument based on the optical system.
