Figure 2
Rowland circle geometry employed for the instrument design [(a) and (b), dimensions not to scale]: a quarter section of a generic doubly bent diffractor; how the crystal analyzer and detector move on the Rowland circle when changing the Bragg angle (bottom). Cylindrical segmentation of the analyzer in the sagittal direction for a multi-analyzer configuration at the two extreme Bragg angles (c). The horizontal and sagittal planes are shown. For simplicity, the Rowland circle and rays volume are displayed only for the central analyzer.
