摘要: The theory of a two-dimensionally focusing double-crystal Bragg spectrometer consisting two crystals bent cylindrically in mutually perpendicular planes is developed. spectral resolution this calculated for asymmetrical geometry diffraction. value the shown to be affected by following factors: an asymmetry factor, crystal bending radius and x-ray source size. Comparison with single-crystal spectrometers Johann, Johann–Hamos, Johannson–Hamos backscattering geometries carried out.
