Title: Stability analysis of cryogenic direct-drive ICF target and a method for fabricating hollow silica aerogel spheres

Abstract

A brief description of the work done under LLNL Subcontract No. 4180405, which expired as of December 31, 1988, is presented. The work performed under this subcontract covered a wide range of research activities which may be generically labeled as Technical Investigation of Cryogenic Laser Fusion Target Fabrication and Characterization.'' However, the specific work performed during the period of October 1, 1987 through December 31, 1988, which this report concentrates on, covers the following three categories of research: Theoretical study of the stability of a thermally induced, uniformly thick liquid fuel layer inside a spherical-shell ICF target. Development of methods for fabricating spherical-shell low-density foam targets using hollow drop generation and sol-gel processing techniques. Further study of the behavior of a liquid D-T mixture layer inside an ICF target using a ternary-mixture approach with the inclusion of convection and thermal diffusion effects.
