Uncertainty Quantification in Plasma Physics Research

Abstract

The objective of this research is to develop and apply tools for characterizing theuncertainty in electron collision cross-sections, systematically vary the resolution inplasma chemistry models, and propagate the uncertainty in cross sections contained inthese chemistry models through reduced order plasma simulations. This work willdemonstrate how the resolution in the plasma chemistry models and uncertainty incollision cross sections can affect the predictions of the plasma dynamics obtained fromthese models. This will advance plasma modeling capabilities by starting to incorporatethe methods of uncertainty quantification into plasma simulation codes, demonstratingthe payoff to increasing confidence in plasma simulations and the system-levelsimulations upon which they rely.
