Technical characteristics of beamline P12

Beamline P12 uses a high brilliance X-ray beam with low scattering background and energy tunability. The beamline is optimized for solution scattering experiments and allows for kinetic SAXS with millisecond time resolution and anomalous SAXS experiments on biologically relevant metals, such as calcium or molybdenum.
