THE ORNL ATOM PROBE SOFTWARE PACKAGE

Abstract
An atom probe software package for on-line control of the instrument and analysis of atom probe and imaging atom probe data has been developed. The package was written to provide the maximum information to the operator and has the flexibility to view the data in the most appropriate mode for the type of analysis being undertaken. The data may be displayed in real time, either individually or in combination, as raw masses or times, ion-by-ion element identification, mass or time spectra, multi-element composition profiles, ladder diagrams, cumulative plots and composition. The data may also be analysed immediately with autocorrelations, cross correlations, Fast Fourier Transforms, and frequency distributions or compared to previously stored data. A built in data base containing isotope abundances and normal charge states of all elements is available for element identification.
