Monochromatization of synchrotron radiation for nuclear resonant scattering experiments

An introduction to monochromatization of synchrotron radiation in the energy range of 5–30 keV is presented for applications involving nuclear resonant scattering. The relevant relationships of the dynamical theory of X-ray diffraction are used to explain basic con-cepts of monochromatization. These relations are combined with ray-tracing techniques to design high-energy-resolution monochromators. Transmission-optimized and energy-resolution-optimized designs that achieve high energy resolutions (106 < E=D E < 108) are discussed separately. Practical silicon monochromators of both types are presented for a variety of nuclear resonances in this energy range. 1
