  • Title: PoDFluX: a new Monte Carlo ray-tracing model for powder diffraction and fluorescence.
    Author: Hansford GM.
    Journal: Rev Sci Instrum; 2009 Jul; 80(7):073903. PubMed ID: 19655961.
    Abstract:
    PoDFluX is a new Monte Carlo ray-tracing program that simulates from first principles x-ray powder diffraction from crystalline materials and x-ray fluorescence from materials with a defined elemental composition. This model has been written primarily for the optimization of miniaturized planetary x-ray diffraction instrumentation but wider applications are certainly possible. A particular strength of the model is the implementation of several variance-reduction techniques for the minimization of execution times. Comparisons of model output with experimental diffraction and fluorescence data show good quantitative agreement.
