Figure 8.1.7.2

Double-crystal monochromator illuminated by SR. The contributions of the source divergence, α_V [less than or equal to γ⁻¹, equation (8.1.2.4), depending on the monochromator vertical entrance slit aperture; see also Colapietro et al., 1992], and angular source size, $[\Delta \theta_{\rm source}]$ , to the range of energies reflected by the monochromator are shown.
