Sketch of the asymmetric Rowland geometry for the MultiFLEXX design with a short analyzer-detector distance. Placing the three analyzer crystals on the Rowland circle would result in significant double scattering, limiting the channel performance. This double scattering effect would be present in all 5 analyzer arrays, where the Rowland geometry is highly asymmetric in all cases. Thus a different geometry for the analyzers was used in the design of MultiFLEXX (see text).
