Schematic of the Rowland circle spectrometer of diameter 1 m in the vertical scattering geometry. A Si(333) single-crystal wafer glued onto a spherical substrate was used as the analyzer, and a Peltier-cooled silicon detector (AMPTEK XR_100CR) was used to detect the emitted X-ray fluorescence. The Fe Kβ emission spectra were collected through a Be gasket which is transparent to the X-ray energy range of approximately 7 keV. |
