文摘

We discuss a three-objective search and reconstruction method for the extraction of spatial structure information from argon-doped implosion cores based on the simultaneous analysis of Heβ and Lyβ X-ray narrow-band images and space-integrated line spectrum data. The search in parameter space is driven by a multi-objective Pareto genetic algorithm. Two alternative implementations of the three objectives are considered. Two- and three-objective analysis of the same set of time-integrated data produce similar temperature profiles but different density profiles.
