Figure 6
CRL-MS model with high-frequency figure errors at 8 keV. (a) Partially coherent simulations show the beam profile up- and downstream of the focal position averaging 104 wavefronts to simulate the radiation emitted by an undulator; (b) the coherent simulations show the beam profile of a plane wavefront being focused; (c) beam propagation near the focal position (beam caustics) for a fully coherent beam (horizontal cut around y = 0); (d) phase and (e) intensity of the PSF calculated focusing a plane-wavefront; (f) demagnified image of the undulator photon source (extended source).
