The CoSAXS beamline is a state-of-the-art multipurpose Small Angle X-ray Scattering (SAXS) instrument with opportunities to use the inherent high coherent properties of the 3 GeV MAX IV ring through X-ray Photon Correlation Spectroscopy (XPCS) experiments. It offers 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 17 m). The optical and mechanical design of the CoSAXS instrument has been carefully developed to preserve the wavefront and the entire coherent flux as much as possible.
This high-performance X-ray beam is complemented by an exceptional pool of sample environments and detector systems. Several techniques are 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.

Floating droplets aid studies of challenging protein solutions

Researchers from University of Copenhagen, Technical University of Denmark and Lund University have recently published a paper showing that the acoustic levitation method can successfully enable studies on high concentrations of proteins in solution. The results have important implications for areas such as pharmaceutical, food and chemical industry. For many applications, such as pharmaceuticals, it’s
