Suppression of higher-order harmonics with V-shaped channel-cut crystal for reflection (440) calculated at energy of X-rays E = 18.78 keV. (a) The output intrinsic rocking curve of the first diffractor, (440) reflection, E = 18.78 keV; (b) input rocking curve of the second diffractor, (440) reflection, E = 18.78 keV; (c) total input rocking curve, reflection (220), E = 9.39 keV (fundamental harmonic); (d) total input rocking curve, reflection (440), E = 18.78 keV (higher-order harmonic). Rocking curves were calculated by applying a computational method for the two-beam case of dynamical diffraction theory (Huang & Dudley, 2003

), and dielectric susceptibilities were used from the Stepanov X-ray server (Lugovskaya & Stepanov, 1991
