Figure 4
A plot of all the data collected on the thick part of the crystal. The symbols represent the following: open circles, I1 FWHM < 2′′; filled circles, 2′′ < I1 FWHM < 10′′; filled squares, 10′′ < I1 FWHM < 20′′; filled diamonds, 20′′ < I1 FWHM < 30′′; filled triangles, I1 FWHM > 30′′. The hyperbolic-like curve is a guide to the eye: the data suggest that, for heat-load variables to the left and below this curve, the thermal distortions will be less than 2′′. Three `heat-load tuning curves' are also shown. Dashed line: 3 mm (H) × 2 mm (V) white-beam single undulator, 100 mA ring current; dotted line: 3 mm (H) × 2 mm (V) white-beam single undulator, 200 mA ring current; thick solid line: 1.5 mm (H) × 0.5 mm (V) white-beam single undulator, 200 mA ring current.
