Numerical evaluation of diffracted intensity by a 250 µm-thick Si 111 symmetric Laue crystal calculated using equation (23) for a bent (R = 1 m) crystal and p = 50 m. (a) On-axis intensity for a photon energy of 8.3 keV. Inset: transverse profile at the focal distances (maximum values): q1 = 651 mm (blue) and q2 = 1330 mm (red). (b) On-axis intensity for a photon energy of 17 keV. Inset: transverse profile at the focal distances (maximum values): q1 = 625 mm (blue) and q2 = 1372 mm (red). |
