Abstract :
In this work, mass spectrum analysis using a new novel software by MATLAB were tested in several liquid metal ion sources (LMAISs) such as AuGeSi, GaIN, ErFeCrNi, and AuGe. The relative intensities of the main ions of each source were determined. In AuGeSi source our results strongly point towards the co-existence of two mechanisms for the emission of doubly-charged monomer ions: direct field evaporation for the Ge2+ and Si2+ ions but Au2+ is formed by the post-ionisation of Au+. In ErFeCrNi source according to Brandon´s criterion Er2+, Fe2+ is likely to be field evaporated as doubly charged ions. Also, in AuSi alloy source Si2+ is directly field-evaporated while Au2+ must formed by the post-ionisation of Au+.
