Structural effects in ICF foam-buffered targets

By R.J. Mason, R.A. Kopp, S.R. Goldman, D.C. Wilson and R.G. Watt

Abstract

Experiments have indicated that low-density foam buffer layers can significantly mitigate the perturbing effects of beam non-uniformities in direct drive laser-matter interactions. A smooth drive is essential to obtaining ignition in the Direct Drive approach to ICF ignition. Consequently, the authors have conducted a detailed study of the mitigating capabilities of foam-buffers, and how to optimize then. Smoothly driven implosions may prove crucial to obtaining the high energy and neutron yields needed for Science Based Stockpile Steward ship applications
