DuMond diagram. [\delta {\theta _{\rm{B}}}] (= 0.07′′) is the angular width of the incident beam on the second crystal used as a monochromator through Slit 2, d[{\theta _1}] (= 0.003′′) that on the third crystal used as the sample through Slit 3 and d[{\theta _2}] (= 0.003′′) the angular resolution of the analyzer obtained by moving Slit 4. [\delta {\lambda _{\rm b}}] (= 1.1 × 10−7 nm) is the bandwidth of the X-ray wavelength through Slit 2 and d[\lambda] (= 4 × 10−9 nm) the wavelength resolution of the analyzer obtained by moving Slit 4.
