Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>A new method for beamline simulation combining ray‐tracing and wavefront propagation is described. The `Hybrid Method' computes diffraction effects when the beam is clipped by an aperture or mirror length and can also simulate the effect of figure errors in the optical elements when diffraction is present. The effect of different spatial frequencies of figure errors on the image is compared with <italic>SHADOW</italic> results pointing to the limitations of the latter. The code has been benchmarked against the multi‐electron version of <italic>SRW</italic> in one dimension to show its validity in the case of fully, partially and non‐coherent beams. The results demonstrate that the code is considerably faster than the multi‐electron version of <italic>SRW</italic> and is therefore a useful tool for beamline design and optimization.</p> </abstract>
