Experimental set-up for diamond anvils experiments. The sample is confined between two opposed anvils (diamond single crystals). In radial diffraction geometry, the direction of the monochromatic X-ray beam is perpendicular to the anvil axis and the data are collected on an area detector orthogonal to the incoming beam. The position and intensity of the diffraction lines are analyzed as a function of the azimuthal angle δ. |
