Foam Fills for Laser-Plasma Instability Suppression

Ogden Jones | 21-ERD-041

Executive Summary

We are developing techniques for using additively manufactured foams to create density and material profiles inside laser-heated hohlraums that absorb more radiation drive energy. If successful, this technique would enable the indirectly driven inertial confinement fusion capsule yields exceeding one megajoule that are crucial to achieving fusion ignition.
