Description générale

PROXIMA 2 is a phase 2 beamline that will feature two undulators in canted geometry providing for two independent experimental stations. The first experimental station (PX2-A) will be dedicated to biological macromolecular crystallography, and it will specialize in the collection of diffraction data from micro-crystals. The second experimental station (PX2-B) is reserved for the future, and its objectives & design are currently under study.
