Abstract

Simulation of optical systems is an important tool for optics design for known applications, and in assessing the potential for new applications. Monte Carlo simulations were developed to model complex reflective x-ray optical systems, including polycapillary lenses and micropore optics. The simulations are fully three-dimensional, tracking both the photon trajectories and optic surface normals as vectors. Simulation verification was performed for a wide variety of optics geometries, x-ray source configurations and photon energies and included comparison with both theoretical modeling and experimental data. Glass defects such as surface roughness and ripple as well as defects in optics geometry such as rotation of micropore walls and profile error in polycapillary optics were incorporated and were shown to have differing effects, including reducing throughput or increasing focal spot size, depending on the source and optic geometry and photon energy.
