A new experimental station for microbeam X-ray scattering at the SSRF BL10U1 beamline

Abstract

Benefiting from the development of high-brilliance synchrotron radiation sources, microbeam X-ray scattering has become a well established scattering-based imaging technology. This article describes the newly constructed time-resolved microbeam small-angle X-ray scattering (µSAXS) experimental station at the BL10U1 beamline at the Shanghai Synchrotron Radiation Facility. The µSAXS endstation provides SAXS/WAXS measurements with a 10 µm hard X-ray beam and a flux of ∼1012 photons s−1. A multi-axis sample stage, an on-axis viewer and in situ experimental apparatus are incorporated to facilitate multi-method scientific experiments in various material fields. As scientific examples, this article explores 1D tomography, 2D mapping and tomographic sectioning based on X-ray scattering to investigate the micro–nanostructures of polymer fiber, spherulite and bamboo samples.
