Mathematical reconstruction of sample microstructures obtained from PIXE elemental maps
A software package developed for quantitative characterization of microstructures with particle-induced X-ray emission (PIXE) measurements is described. The system includes the following parts: a solution of the PIXE signal equation with respect to the beam profile function by the Fourier method and a reconstruction of the elemental concentration distribution from a measured signal by the method of successive substitutions. The results of applying the developed program to the experimental distribution maps obtained from a micro-structured reference material are compared with the known properties of this reference material.
