Abstract

The complexity of the physical phenomena involved in plasma generation and acceleration makes it difficult to implement high-fidelity predictive models. Bayesian statistics offers a powerful framework for data interpretation, based on experimental data and available prior knowledge. This paper presents the results obtained with a numerical tool based on statistics, which is applied to the study of plasma evolving in the acceleration chamber of a variable-section ablative pulsed plasma thruster.
