摘要
在俄罗斯新能源研究所的Angara-5-1装置上对双层钨丝阵的辐射参数进行了实验研究,将不同结构的双层钨丝阵的实验结果及双层钨丝阵与单层钨丝阵的实验结果进行了比较。根据理论模拟提出的4种双层丝阵内爆动力学模式对3次中俄联合实验双层丝阵辐射功率结果进行了分析。双层丝阵的外层与内层同步内爆后,内层相对均匀等离子的分布将有效改善外层等离子体时空分布的均匀性,与单层丝阵相比,X射线辐射功率增加了32%。
Abstract
Implosions with nested tungsten wire array were performed at the Angara-5-1 facility in Russian Research Centre. The experimental results of nested tungsten wire array are compared with those of single array. Radiation parameters of nested array are discussed based on four different dynamic models. When the implosions of outer and inner wire arrays are synchronized, the relatively uniform distribution of inner layer plasma will improve the uniformity of outer layer plasma. As compared with single array, nested array has an increase of 32% in X-ray radiation power.
