Summary

- Spectroscopic and interferometric characterization of nuclear fusion plasmas: Inertial confinement fusion (ICF) has been proposed for decades, and especially after the experimental demonstration of net energy gain in December 2022, as a promising source of clean, sustainable, and virtually limitless energy. Our research aims to contribute to its advancement by exploring alternative ignition schemes, such as shock-ignition or magnetized inertial fusion. Specifically, our work focuses on developing X-ray spectroscopy and interferometry techniques to diagnose the extreme conditions of density and temperature reached by plasma matter in scenarios relevant to ICF. Through detailed spatiotemporal characterization, we seek to better understand the dynamics of ablation-compression fronts or energy transport phenomena in implosions. Our investigation is grounded in fundamental concepts of atomic physics in dense and hot plasmas, collisional-radiative atomic-kinetics, and Stark-Zeeman spectral line broadening theory. These theoretical aspects are integrated into advanced computational simulations employing Monte Carlo methods, molecular dynamics, and machine learning algorithms.
