About GUPIX and GUPIXWIN

GUPIXWIN is a versatile software package for fitting PIXE spectra from thin, thick, intermediate and layered specimens. It extracts peak intensities and converts these to concentrations via the H-value standardization method. X-ray excitation may be via protons, deuterons, He-3 or He-4 ions; X-ray spectrometry may be via Si(Li) or Ge detectors. Interactive or batch processing may be selected.

In either its earlier GUPIX form or in the newer GUPIXWIN form, this software has been supplied to about 140 ion beam analysis laboratories in 30 countries. GUPIX has been tested extensively using various standard reference materials and inter-comparisons.

The Windows version GUPIXWIN became available in version 1.1 on 1 July 2005. It retains most of the features of the original GUPIX and offers a marked increase in user convenience. It was presented in the autumn of 2005 to two GUPIX Training Schools, one in Paris and one in Florence. As a result of the very large volume of feedback and suggestions, further development was done to incorporate the needs of users, leading to Version 1.3. Development of V2.0 was completed in early 2007, providing an elegant new output manager together with batch mode for both single-detector and dual-detector operation. V2.1 was released early in 2008 and included an extension of proton energies to 5 MeV, plus various improvements that were suggested at the PIXE2007 conference in Mexico.

We recommend that any remaining users of the old DOS version of GUPIX should upgrade to GUPIXWIN. We are no longer making updates, improvements and corrections to GUPIX whereas GUPIXWIN is being upgraded on a continuing basis. Moreover some GUPIX users have encountered problems in running it on new laptops.
