MultiSIMNRA: A computational tool for self-consistent ion beam analysis using SIMNRA

•MultiSIMNRA enables the self-consistent analysis of multiple ion beam techniques.•Self-consistent analysis enables unequivocal and reliable modeling of the sample.•Four different computational algorithms available for model optimizations.•Definition of constraints enables to include prior knowledge into the analysis. SIMNRA is widely adopted by the scientific community of ion beam analysis for the simulation and interpretation of nuclear scattering techniques for material characterization. Taking advantage of its recognized reliability and quality of the simulations, we developed a computer program that uses multiple parallel sessions of SIMNRA to perform self-consistent analysis of data obtained by different ion beam techniques or in different experimental conditions of a given sample. In this paper, we present a result using MultiSIMNRA for a self-consistent multi-elemental analysis of a thin film produced by magnetron sputtering. The results demonstrate the potentialities of the self-consistent analysis and its feasibility using MultiSIMNRA.
