X-Ray Diffraction Apparatus at Home Facilities of the Center for Structural Biology at the University of Kentucky

Local Rigaku-MSC RAXIS IV and RAXIS IV++ diffractometers share a single X-ray generator (top picture). The former has been upgraded with a new set of mirrors for high efficiency.   The Cryo-Xe (scroll down to bottom picture) allows us to introduce heavy inert atoms (Xenon) into a crystal at cryogenic temperatures.  Localization of these atoms in the crystal is useful for phase determination.

R-AXIS and R-AXIS++ X-ray diffractometers share one X-ray source in our laboratory at UK.
