摘要: A general theoretical approach based on the results of statistical optics is used for analysis transverse coherence properties 3-rd generation synchrotron sources and x-ray free-electron lasers (XFEL). Correlation wavefields are calculated at different distances from an equivalent Gaussian Schell-model source. This model to describe five meter undulator source storage ring PETRA III. In case XFEL decomposition fields into a sum independently propagating modes these new sources. detailed calculation performed parameters SASE1 European XFEL. It demonstrated that only few contribute significantly total radiation field
