In 1990s, the emergence of the 3rd generation synchrotron user facilities equipped with undulator sources, stimulated pioneering works on interaction of coherent X-ray beams with matter, resulted in the development of X-ray photon correlation spectroscopy (XPCS) technique capable to probe nanoscale fluctuations up to kHz frequencies using dynamics of speckle pattern given by scattering of coherent X-ray beam from the sample. More recently (and highly aided by the development of modern high-throughput data analysis algorithms), coherent X-ray diffraction imaging (CXDI), also known as lensless imaging, revolutionized the field of X-ray microscopy, finally bringing users the possibility of non-destructive 2D and 3D imaging of complex structures with unprecedented −10 nm resolution. However, strict requirements to transverse coherence of X-ray probe put serious limits on further development of CXDI-based techniques at the 3rd generation facilities, where coherent flux after spatial filtering becomes unacceptably small at energies above -20 keV. At the same time, the latter was used as one of the strongest arguments of the user community for push towards construction of multibend-achromat-based 4th generation of storage rings with ultra-low emittance. Whereas at the 3rd generation facilities the phase volume of undulator source was dominated by electron beam emittance with negligible influence of other factors, the estimation and minimization of undulator source phase volume at 4 th generation facilities requires more elaborate approach taking into account electron beam energy spread and matching of phase-space ellipses between electron and X-ray beams. Here we present estimations of coherent flux at different energies available for future users of ultra-low-emittance SKIF storage ring (to be commissioned in 2023) and discuss ways of its optimization.
