Abstract

Polycapillary optics consist of hundreds of thousands of tiny hollow tubes that utilize total external reflection to redirect x-rays incident at grazing angles. These optics have been developed for various applications, from beam filtering to x-ray collimating or focusing. A fully three-dimensional Monte-Carlo-based ray-tracing simulation of polycapillary optics has been developed to model a variety of optics geometries. Good agreement to experimental data was found with a small number of fitting parameters.
