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 concepts 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/ΔE < 108) are discussed separately. Practical silicon monochromators of both types are presented for a variety of nuclear resonances in this energy range
