Abstract

In this contribution we discuss two major classes of transversely partially coherent x-ray sources: undulators in storage rings and SASE free-electron lasers. We address similarities and differences in terms of statistical and coherence properties, highlighting their relation with state-of-the-art numerical methods used to simulate the emitted wavefronts and their propagation down a beamline. We also report on recent developments based on simplifying analytical approximations and the use of physical models, leading to fast techniques with improved numerical efficiency particularly suitable for realistic description of spontaneous emission in undulator sources.
