Figure 4
Photograph of the IXS single-analyser spectrometer superimposed with the Rowland circle geometry (represented by the dashed red circle). Monochromatic X-rays are focused at the sample and the scattered and fluorescence X-rays are collected by the analyser crystal that selects a narrow energy band of these X-rays which are then focused at the detector position. The spectrometer energy is scanned by varying the Bragg angle of the analyser whilst maintaining the Rowland circle geometry. Note that a helium flight path, which reduces the effect of air absorption, is omitted from the photograph for clarity.
