Ultimate small-angle resolution for probing large Bragg spacings

Here we will show how the Empyrean instrument can easily be configured for USAXS experiments with a Bonse-Hart type of setup and demonstrate the good performance. The setup makes use of standard high-resolution optical components that are also used for the characterization of epitaxial layers.

Ultra-small-angle X-ray scattering (USAXS) is complementary to conventional small-angle X-ray scattering (SAXS). By sacrificing intensity in favor of resolution, in a USAXS experiment the small-angle resolution is strongly pushed to the ultimate limits. This enables to characterize larger particles and to probe larger Bragg spacings, in the range of hundreds of nanometers. By combining USAXS, SAXS, WAXS and ultimately PDF data, multi-level (hierarchical) structures can be analyzed on different length scales.
