Figure 3
Finite element analysis of a bent crystal: displacement field (top), (middle) and (bottom). The z = 0 mm surface is coated, and the surface stress is 6 N m−1. The colour scale is from −1.4 nm (blue) to 1.4 nm (red). White lines are contours of constant displacement (solid) and the diffracting planes with displacements magnified (dashed). The rectangle indicates the imaged area. |
