AbstractAt ILE, Osaka University, the development of large shells for a future laser fusion reactor and the improvement of the characterization technique for plastic shells used in current implosion experiments with the GEKKO XII laser system have been conducted. In the former, large polystyrene shells with 30–150-μm walls have been successfully fabricated using the conventional emulsion method. Our experimental results indicate that there is some centering force by which a non-uniform emulsion becomes uniform during the solidification process in the emulsion method. A model for this centering force is presented.
大阪大学激光工程研究所（ILE）正在进行用于未来激光聚变反应堆的大型塑料壳层的研制，以及用于当前GEKKO XII激光系统内爆实验的塑料壳层表征技术的改进。在前者中，已采用传统乳液法成功制备了壁厚为30–150微米的大型聚苯乙烯壳层。我们的实验结果表明，在乳液法的固化过程中，存在某种定心力，能使不均匀的乳液变得均匀。我们提出了该定心力的模型。
