Figure 5
Horizontal beam size [\Sigma_{h}] and lateral coherence length lch at a nanofocusing optic as a function of source size [\sigma_{h}] for four different emittances. The squares indicate parameter values comparable with those in the ESRF low- and high-β sections (Sette, 2012BB22), the circles those in low- and high-β sections at PETRA III (https://photon-science.desy.de/facilities/petra_iii/machine/parameters/index_eng.html ). The lateral coherence length lch is in general much smaller than the beam size and varies only weakly with the emittance.
