Abstract

We describe the new implementation in the ray-tracing code SHADOW based on a “hybrid method” developed recently. The code calculates the diffraction effects from an optical element by means of wavefront propagation, and combines the result with that from regular ray-tracing. This hybrid procedure is invoked when diffraction is present (e.g., beam clipped by an aperture or the finite size of the optics) by user demand. The code enables the simulation of mirror figure errors in the framework of wave optics. The simulation of a complete beamline based on the far-field approximation is demonstrated. The near-field propagation is also implemented for individual optics. Finally, the applicable conditions and limitations of the new code are discussed.
