To attain optimum performance in applications such as x-ray imaging and spectroscopy, a spherically bent crystal must diffract well across its entire surface. X-ray topography of sample crystals shows isolated regions where diffraction is problematic, even for a crystal where inspection with visible light does not suggest problems. Covering problem spots may improve the crystal’s focus and decrease the background. We explore the special properties of synchrotron radiation to examine typical spherical crystals from alpha-quartz, in a perpendicular geometry that is especially convenient to examine sagittal focusing.
