Remarks on the diffraction by the diamonds of the high-pressure diamond-anvil cell

Abstract

The diffraction by diamonds of a diamond-anvil cell has been observed to cause sharp dips in the intensity transmitted by the cell. As a result, the intensities of sample reflections measured in X-ray single crystal studies at high-pressure are significantly reduced when the diamond diffraction attenuates either the beam incident on the sample, or the one diffracted from it. This effect should be taken into account in the data collection, by avoiding, for each reflection, the diffractometer settings at which diffraction from the diamonds occurs.
