Multi-Objective data analysis using Bayesian Inference for MagLIF experiments

ORAL

Abstract

The MagLIF concept [1] has recently demonstrated Gbar pressures and confinement of charged fusion products at stagnation [2,3]. We present a new analysis methodology that allows for integration of multiple diagnostics including nuclear, x-ray imaging, and x-ray power to determine the temperature, pressure, liner areal density, and mix fraction. A simplified hot-spot model is used with a Bayesian inference network to determine the most probable model parameters that describe the observations while simultaneously revealing the principal uncertainties in the analysis.
