(a) Calculated reflectivities (Bragg case) of the five 2.08 µm thick independent single crystals in the stack, for a traction force of 130 N. (b) Total reflectivity of the stretched Si 400 single crystal (10.4 µm thick single-crystal stack) for a plane and monochromatic wave beam. (c) An expected non-dispersive double-crystal rocking curve based on the convolution of the reflectivity curves of the monochromator (thick and perfect Si 400 single crystal) and the stretched Si 400 crystal. |
