Improved Ion Sputter Model

To address the validity of models to reproduce experimental sputter results, I used the new data from the irradiation experiments performed by our collaborators in Vienna and compared it to pre-existing sputter models.

The lack of agreement between the results of established models and laboratory experiments led to me being involved in co-developing two modules in the well established binary collision approximation code SDTrimSP. The modules thereby improved how the code determines densities for mineral samples, and added a new way of setting binding energies based on known, tabulated data. An in-depth discussion of the different ways of modeling sputtering including the new modules in SDTrimSP is given in the manuscript published in the Planetary Science Journal.
