SPring-8 is a third-generation synchrotron radiation facility under construction by the JAERI-RIKEN SPring-8 Project Team. Excellent advantages of its undulator sources for protein crystallography are mentioned, and the design concept of the Bio-Crystallography (MIR-OAs) beamline is expressed. This is a public beamline with the undulator source for routine analyses of macromolecular crystallography by the multiple isomorphous replacement phasing with optimized anomalous scattering.
