Figure 1
Schematic of the DuMond geometry. The Laue analyzer is bent to a cylindrical shape with curvature of RC. The light is diffracted by crystal planes oriented in the same direction as the incoming beam, instead of perpendicular planes as in Bragg geometry. The emission is collected from a point-like source and imaged on a detector. When operating in on-Rowland geometry the source and the Laue crystal are located exactly on the Rowland circle and the distance is RC. When operating in off-Rowland geometry, the Laue analyzer has an offset from the Rowland circle. The detector is behind the analyzer.
