(a) Scheme of a diamond crystal (5 mm × 5 mm × 0.05 mm) held and cooled over 2 mm × 5 mm on both sides. (b) Finite-element geometrical model of a half diamond crystal, showing the symmetry condition on the right edge plane. (c) Zoom of the half volume of the crystal intercepted by the X-ray FEL with Gaussian power distribution in beam cross section (x–y) and in-depth (z) variable power absorption. |
