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