Figure 5
Calculated reflectivity curves for a cylindrically bent Si(hhh) crystal. The thickness is 1.2 mm and the angle between the Bragg planes and the surface normal is χ = 15°. The Bragg angle is 4.54°, corresponding to energies of (a) 25 keV reflected by Si(111), (c) 75 keV by Si(333) and (d) 100 keV by Si(444). The combined reflectivity curve [R(θ)]² for the fundamental reflection and perfectly matched crystals is shown in (b).
