Comprehensive Overview of the Beamline:
X-ray, similar to visible light, exhibits diverse imaging mechanisms and abundant contrast sources. Information derived from absorption, scattering, fluorescence, and phase can be utilized to observe and analyze various physical changes, chemical reactions, and nanostructures. The soft X-ray imaging beamline operates within an energy range of 260–1600 eV, facilitating high-resolution three-dimensional structural analysis and elemental absorption edge investigations. Within the 'water window' spectral range (284 eV – 530 eV), high-contrast, nondestructive three-dimensional imaging of hydrated biological specimens (such as cells) can be directly performed, yielding subcellular three-dimensional structures and insights into drug/material interactions with cells. This capability serves as a vital tool for addressing interdisciplinary scientific questions at the interface of materials science and life sciences. By adjusting the energy, absorption edge imaging of light elements and transition metals can be performed, enabling acquisition of three-dimensional structural and elemental distribution information of materials. This facilitates the provision of three-dimensional structural and elemental data to guide the design of critical light materials in fields and industries such as materials science, energy, and catalysis.
