Comparison of various simulation models (lines) and experimental results (blue circles) for 1 keV amu−1 H (A) and He (B) impactors, respectively. Simulation data stem from SRIM (dotted beige line), SpuBase (dashed, pink), SDTrimSP with the default parameters (dashed-dotted, teal) and with the parameters proposed by Szabo et al.22 (solid, blue). Additionally, the arrows quantify the offset between experiment and simulation, and the lighter colored lines give the simulations scaled to match experimental data. The asterisk in “SDTrimSP*” denotes the use of the parameter set proposed by Szabo et al.22 combined with this scaling factor. Experimental error bars are estimated from ion current fluctuations during the measurements and from the quality of fits to the QCM resonance frequency.
