Microphysics Studies of Hohlraum Dynamics

Drew Higginson | 17-ERD-060

Executive Summary

We are exploring the use of advanced kinetic simulation tools to understand the impact of microphysics in gas-filled laser target capsules used in pursuit of inertial confinement fusion. This research will improve the physics basis for predictive models and identify the most important steps for developing a higher fidelity kinetic target-capsule simulation capability.
