APS Small Angle X-ray Scattering (SAXS) Beamlines
Ten different small-angle X-ray scattering (SAXS) beamlines are accessible to the APS general user (overview). The combined capabilities of these beamlines span a broad range of reciprocal space and X-ray photon energy allowing for investigations from many disciplines of science including biology, materials science, environmental science, chemistry, medicine, and physics. Coupled with a high data throughput and fast time-resolved measurement capabilities, these instruments enable an efficient use of the high intensity and high brilliance APS X-ray source. Some of the beamlines have provided examples of their data.
