SHADOW3: a new version of the synchrotron X-ray optics modelling package

Abstract

A new version of the popular X-ray tracing code SHADOW is presented. An important step has been made in restructuring the code following new computer engineering standards, ending with a modular Fortran 2003 structure and an application programming interface (API). The new code has been designed to be compatible with the original file-oriented SHADOW philosophy, but simplifying the compilation, installation and use. In addition, users can now become programmers using the newly designed SHADOW3 API for creating scripts, macros and programs; being able to deal with optical system optimization, image simulation, and also low transmission calculations requiring a large number of rays (>10 6 ). Plans for future development and questions on how to accomplish them are also discussed.

X-ray optics testing beamline 1-BM at the advanced photon source

“…The available vertical divergence at 11 keV is 157 μrad FWHM which corresponds to a vertical beam size of 4.8 mm at the entrance the B-station and 8.4 mm at the entrance to the C-station. Here, the vertical beam divergence was calculated by SHADOW [3] and served to corroborate physical measurements. The Be windows were not changed.…”

A hybrid method for X-ray optics simulation: combining geometric ray-tracing and wavefront propagation

“…In this paper the SHADOW code (Cerrina, 1984;Sanchez del Rio et al, 2011) is used as the ray-tracing program and the reference for the coordinates definition. The spatial coordinates of the rays are defined in positions (x, y, z) and direction cosines (v x , v y , v z ).…”

Design of a multilayer-based collimated plane-grating monochromator for tender X-ray range

“…4(c) reveals their corresponding resolving power in the same colour. Here, the resolving power and energy flux (photons s À1 ) at the sample position are taken from the result of ray tracing using SHADOW (Sanchez del Rio et al, 2011). The efficiency, flux and resolving power of the conventional cPGM with single-layer coating on both the plane mirror and grating working at À1st order and high-resolution mode (C ff = 4) are also shown in Fig.…”
