In this paper, ionization processes of secondary ions during ToF-SIMS dual beam depth profiling were studied by co-sputtering with 500 eV cesium and xenon ions and analyzing with 25 keV Ga + ions. The Cs/Xe technique consists in diluting the cesium sputtering/etching beam with xenon ions to control
