Answer:
The physical infrastructure for X-ray crystallography structural biology includes synchrotrons, which are affordable by a nation. There are 47 in the world (lightsources.org). Each synchrotron provides a number of beamlines for experiments, usually including several optimized for macromolecular X-ray crystallography, often some for other structural biology techniques including SAXS (Small-Angle X-Ray Scattering) and CD (Circular Dichroism), and usually some beamlines for material sciences and other non-biological applications.
