Abstract

Abstract

Measurements of the mass ablation rate of aluminum (Al) have been completed at the Omega Laser Facility. These measurements show that the mass-ablation rate of Al is higher than plastic (CH), comparable to high density carbon (HDC), and lower than beryllium. The mass-ablation rate is consistent with predictions using a 1D Lagrangian code, Helios. The results suggest Al capsules have a reasonable ablation pressure even with a higher albedo than beryllium or carbon ablators and further investigation into the viability of Al capsules for ignition should be pursued.
