High-Fidelity Kinetic Modeling of Plasmas in Z-Pinch and Pulsed-Power Configurations

Genia Vogman | 18-ERD-048

Executive Summary

Leveraging the latest advances in supercomputing and applied mathematics, this research aims to apply newly developed, high-accuracy computational algorithms to investigate the fundamental fine-scale physics of plasmas. If successful, the results will greatly advance our understanding of plasma science, with application to national missions in fusion energy and nuclear weapons stockpile stewardship.
