The CoSAXS beamline will be a state-of-the-art multipurpose Small Angle X-ray Scattering (SAXS) instrument with opportunities to use the inherent high coherent properties of the MAX IV machine through X-ray Photon Correlation Spectroscopy (XPCS) experiments. It will offer high brilliance, monochromatic and tuneable X-rays, with outstanding performance in low beam divergence, high X-ray flux, and variable beam size in both directions in the full range of the sample-detector distances provided by the beamline (up to 18 m). The optical and mechanical design of the CoSAXS instrument will be carefully developed to preserve the wavefront and the entire coherent flux as much as possible.
This high-performance X-ray beam will be complemented by an exceptional pool of sample environments and detector systems. Several techniques will be available through modular operation: time resolved SAXS, SAXS/WAXS, protein solution SAXS, microfocusing SAXS, anomalous X-ray scattering and XPCS. It will meet the demands of a large and broad community of users.
