Elliptically Bent X-Ray Mirrors with Active Temperature Stabilization

Figure 12

Temperature-induced surface slope change with a 3.2 C (24.5 C–21.3 C) increase in the ambient temperature. The dashed line is a linear fit. Unlike the previous case without temperature stabilization (Figure 8), here slope changes are not detectable within a measurement uncertainty of 3 nrad/mm that corresponds to a radius of curvature above 300 km.
