Improved set of Auger data analysis programs for physical electronics Auger spectrometer systems
This report describes a set of utility programs for the display and analysis of Auger spectral data collected with Physical Electronics (PHI) Auger Spectrometers using the embedded computer data acquisition system that is standard on PHI spectrometers. These programs are designed to replace the routines supplied by the manufacturer and offer the user greater flexibility. All routines will run on standard PHI systems equipped with HP2648 or HP2623 computer terminals. The major feature of these programs is the ''windowing'' capability for quantitative analysis of a list of elements. Spectra are collected and saved to disk using the PHI acquisition system in the usual fashion, except that it is not necessary to specify the elements that are present before the analysis is performed. The spectrum can be divided into any convenient arrangement of energy regions. This procedure permits the energy regions for data acquisition to be larger than the element windows to minimize the effect of the end points on the numerical differentiation. It is also easier to analyze closely spaced peaks, such as oxygen and chromium. When the spectra are processed, each region is automatically differentiated and displayed in sequence, with the energy windows for the Auger peaks marked in reverse video. Window limits can be moved easily, and multiple files can be analyzed using one setup. Results are stored on disk, together with the raw peak-to-peak heights and the sensitivity factors used. These disk files can then be read by simple auxiliary programs to average or tabulate results. 3 refs., 1 fig.
