Experimental setup at the 3-ID beamline of the Advanced Photon Source for characterizing the X-ray transmission properties of the DFCA. (a) Diamond premonochromator. E = 8979 eV, [\Delta E] ≃ 600 meV. (b) Ionization chamber. [\Phi] ≃ 1013 photons s−1. (c) Si(444) monochromator. [\Delta{E} ] = 65 meV. (d) Ionization chamber. [\Phi] ≃ 3×1011 photons s−1. (e) Slit, typically 0.5 mm × 0.5 mm. (f) Amorphous scatterer, plexiglass. (g) Pin diode, monitor. [\Phi ]1010 photons s−1. (h) Si(111) double flat-crystal analyzer, [\Delta E] = 120 meV. (i) Detectors on translation stages: scintillation counter with slit or image plate. [\Phi] ≃ 100 photons s−1.
