Figure 5
Width of the Gaussian component of the pseudo-Voigt line as a function of the meridional radius of curvature of M1, RmM1. Data were collected with the vertical principal slits at 2 mm so realizing a high-flux configuration (vertical divergence 90 µrad). The point of the arrow marks the theoretical radius of curvature for perfect collimation and the theoretical value of the energy resolution (crystal intrinsic). |
