DEVELOPMENT OF DEUTERATED POLYSTYRENE SHELLS FOR LASER FUSION BY MEANS OF A DENSITY-MATCHED EMULSION METHOD

High quality, microdeuterated polystyrene shells were fabricated using a density-matched emulsion method. The diameter and wall thickness of the shell ranged from 100 to 1500 and 3 to 15-mu-m, respectively. The sphericity, the wall thickness uniformity, and the surface smoothness were 99.8%, 99.3% and < 0.1-mu-m, respectively. A defect on the inner surface of the shell was smeared by replacing water in the shell with ethanol prior to the final drying process.
