PASS (PIXE ANALYSIS SHELL SOFTWARE): A COMPUTER UTILITY PROGRAM FOR THE EVALUATION OF PIXE SPECTRA

This paper describes a shell which facilitates the use of the existing PIXE analysis software package PIXAN. In this work, we designed, wrote and examined several PIXE spectra in a utility program that is called WPASS. The WPASS program merely links PIXAN modules and makes their use more convenient than before. The WPASS program handles automatically PEAKFIT (BATTY) and THICK programs. It outputs the results into several files belonging to the same data file. These include converting data files from one-column-format OCF to PIXANPC format; control, graphics, and result files from PEAKFIT; control and result files from THICK; options for graphical plotting the results on the PC and converting the graphics files for their components for publications of the results. WPASS has new features that consider the secondary interelement fluorescence. WPASS has been used successfully for the analysis of PIXE spectra and inner-shell ionization studies.
