Abstract
A software package developed for quantitative characterization of microstru ctures with particle-induced X-ray emission (PIXE) measurements is describe d. The system includes the following parts: a solution of the PIXE signal e quation with respect to the beam profile function by the Fourier method and a reconstruction of the elemental concentration distribution from a measur ed signal by the method of successive substitutions. The results of applyin g the developed program to the experimental distribution maps obtained from a micro structured reference material are compared with the known properti es of this reference material.
