Coherent fraction of radiation [\zeta^{\,\rm{CF}}] as a function of the electron beam emittance [\varepsilon_{\rm{e}}] for the different values of the photon energy and energy spread in one transverse direction. Triangles are XRT simulations, circles are analytical calculations performed according to equation (13)[link]. Red, green and blue colour correspond to 0, 1 × 10−3 and 2 × 10−3 relative energy spread values, respectively. Dashed vertical line corresponds to the value of the electron emittance of 10 pm rad. Note the different scale for 500 eV coherent fraction value.
