Single,Double, or Triple plate BRF?
X-ray crystallography is used to determine the physical orientation of the birefringent crystal before and after it is cut/sawn from the boule after growth. Other then that, X-rays have nothing to do with the process.
The X-ray beam, after being projected through the crystal under test produces a pattern of diffraction spots after scattering from the crystal structure. Measuring the position and angles of the spot pattern let's you work out the 3d orientation of the crystal relative to its optical axis.
X-RAYS cannot alter the solidified crystal's structure.
