Abstract One of the great challenges of inertial confinement fusion and high energy density experiments is understanding the effects of mix on thermonuclear burn. The MARBLE campaign, conceived at Los Alamos National Laboratory, aims to gather new insights into this issue by utilizing unique target capsules containing polymer foams of variable pore sizes, tunable over an order of magnitude. Such capsules allow the degree of initial heterogeneity to be controlled experimentally for the first time. Here, we describe the various characterization efforts used to gain understanding of the chemical structure and behavior of the foam. Previous experiments were not sensitive to foam physical properties, and the MARBLE platform has aided in the development of techniques to measure foam properties such as deuterium content, density variation, hydrogen adsorption, and pore size and volume distribution.

用于大理石混合形态学实验的分级可调孔径聚合物泡沫的材料表征

摘要 惯性约束聚变和高能量密度实验的一大挑战是了解混合对热核燃烧的影响。在洛斯阿拉莫斯国家实验室构思的 MARBLE 活动旨在通过利用独特的目标胶囊来收集对该问题的新见解，该胶囊含有可变孔径的聚合物泡沫，可在一个数量级内进行调节。这种胶囊允许首次通过实验控制初始异质性的程度。在这里，我们描述了用于了解泡沫的化学结构和行为的各种表征工作。以前的实验对泡沫物理特性不敏感，而 MARBLE 平台有助于开发测量泡沫特性的技术，例如氘含量、密度变化、
