X-Ray Crystallography Beamlines

The NYSBC operates two synchrotron beamlines at the Brookhaven National Laboratory on Long Island.

X4A beamline is fully tunable and was originally designed to test multiwavelength (MAD) phasing, a methodology now widely used for solving biological crystal structures. X4A, in operation since 1992, is consistently ranked among the five most productive of more than 100 beamlines in the world.

X4C, NYSBC’s newly operational beamline, has more limited tunability but its flux density at the crystal sample is higher than that from X4A. Both beamlines are equipped with CCD detectors and have just undergone major renovations of goniometers and robotic sample changers.
