A spectroscopic method is discussed to measure core and compressed-shell conditions in thick-wall plastic-shell implosions filled with deuterium and a tracer amount of argon. Simultaneous observation over a broad photon energy range of the argon line emission and the attenuation and self-emission effects of the compressed shell confining the core yields enough information to extract average temperature and density conditions in both core and compressed shell. The spectroscopic analysis also provides an estimate of the target areal density which is an important characteristic of inertial confinement fusion implosions.
本文讨论了一种光谱学方法，用于测量充满氘和微量氩气的厚壁塑料壳内爆中核心和压缩壳层的状态。在较宽的光子能量范围内，同时观测氩线发射以及限制核心的压缩壳层的衰减和自发射效应，可获得足够的信息来提取核心和压缩壳层中的平均温度和密度条件。光谱分析还能估算靶面密度，这是惯性约束聚变内爆的一个重要特征。
