Proton Induced X-Ray Analysis (PIXE)
An inter-comparison of PIXE spectrometry software packages was organized by the IAEA in 2000. It was based on a prepared set of calibration and test spectra representing four typical samples analysed by PIXE laboratories:
1. A thin aerosol material
on a thin polycarbonate backing,
2. A thick stainless steel sample containing Nb and Mo,
3. A thick sample of biological material, and
4. A thick glass sample.
The procedures use to generate the test spectra, the methods used in the inter-comparison exercise and the outputs of the participating software packages has been published as IAEA-TECDOC-1342 "Intercomparison of software packages for analysis of PIXE spectra". This document can be downloaded from here. The calibration and test spectra can be downloaded from here.
This inter-comparison exercise has been described in two papers published in Nuclear Instruments Methods:
