The focusing performance in terms of peak gain and fraction of photons in the central speckle versus the focal spot size is assessed at a mean X-ray photon energy of #!E = 8.5 keV for different X-ray bandwidths, assuming a constant integral energy. #!N = 1 to 60 lenses with #!R = 50 µm were used to model the data, using a perfect lens shape (blue lines) and the mean deformation (orange lines) as shown in Fig. 4[link].
