Small Angle X-ray Scattering (SAXS)

A laboratory small-angle X-ray scattering (SAXS) system with a dual energy (Mo and Cr) source has been designed with the aim of studying the heterogeneity in high-Z metallic structural materials such as steels (Fe alloy) and other materials. With the combination of Mo and Cr energies, various camera lengths (maximum of 2400 mm), and an area detector, three decades of q range has been achieved, from 0.024 to 14 nm-1. In real space, the probing periodic distance is a maximum of 261 nm. In addition to having Mo and Cr sources, a flexible sample mounting stage permits measurements on a wide range of materials in transmission geometry.
