Abstract

The synchrotron-based hard X-ray nanotomography beamline, named 7C X-ray Nano Imaging (XNI), was recently established at Pohang Light Source II. This beamline was constructed primarily for full-field imaging of the inner structures of biological and material samples. The beamline normally provides 46 nm resolution for still images and 100 nm resolution for tomographic images, with a 40 µm field of view. Additionally, for large-scale application, it is capable of a 110 µm field of view with an intermediate resolution.

摘要

基于同步加速器的硬X射线纳米断层成像光束线,名为7C X射线纳米成像(XNI),最近在浦项光源二期建成。该光束线主要用于生物和材料样品内部结构的全场成像。该光束线通常为静态图像提供46纳米的分辨率,为断层图像提供100纳米的分辨率,视场为40微米。此外,对于大规模应用,它能够以中等分辨率实现110微米的视场。
