Resonant inelastic X‐ray scattering (RIXS) experiments require special sets of near‐backscattering spherical diced analyzers and high‐resolution monochromators for every distinct absorption‐edge energy and emission line. For the purpose of aiding the design and planning of efficient RIXS experiments, comprehensive lists of suitable analyzer reflections for silicon, germanium, α‐quartz, sapphire and lithium niobate crystals were compiled for a multitude of absorption edges and emission lines. Analyzers made from lithium niobate, sapphire or α‐quartz offer many choices of reflections with intrinsic resolutions currently unattainable from silicon or germanium. In some cases these materials offer higher intensities at comparable resolutions. While lithium niobate, sapphire or α‐quartz analyzers are still in an early stage of development, the present compilation can serve as a computational basis for assessing expected and actual performance. With regard to high‐resolution monochromators, bandpass and throughput calculations for combinations of double‐crystal, high‐heat‐load and near‐backscattering high‐resolution channel‐cuts were assembled. The compilation of these analyzer and monochromator data is publicly available on a website.
