Figure 5
Quartz rocking-curve broadening (left axis) estimated by FEA (green) compared with measurements in air (blue). Also plotted are the maximum temperature rises (right axis) calculated by FEA (orange) and by the spreader model (red). Inset: FEA volumetric normal strain profile for quartz at full load near the beam center. Asymmetries are caused by the anisotropy in both thermal conductivity and expansion coefficient. Below, a histogram of the weighted distribution of Bragg angle displacements. |
