  • 辐射驱动内爆最大压缩时刻芯部的状态的研究是惯性约束聚变 (ICF)研究中的核心的研究内容.芯部的状态是指温度和密度. 利用Multi1D模拟的芯部温度和密度的空间分布, 通过局域热平衡模型计算了芯部区域归一化的发射强度的空间分布, 提出了芯部的温度和密度的空间分布满足高斯分布的假设,采用参数最优化算法, 可以推断芯部的温度和密度空间分布的峰值和半高宽. SGIII原型装置上的内爆芯部发射实验处理结果表明,芯部的温度峰值为1.7 keV, 密度峰值为1.2 g/cm3,温度和密度分布的半高宽分别为20 μm和18 μm.
    Core condition studies of radiation driven implosion for maximum compression time are the key contents of inertial confinement fusion research. Core conditions refer to the electron temperature and mass density in core region. The spatial distribution of core emission is calculated based on local thermal equilibrium by Multi one-dimensional simulation of core temperature and density. Assumption is made that the core temperature and density distributions each meet a Gauss distribution. Peak values and full widths at half maximum of temperature and density spatial distribution can be inferred by parameter optimization. The data-processing for implosion experiment on Sheng-GuangIII prototype facility indicates that the peak values of temperature and density are 1.7 keV and 1.2 g/cm3 respectively. The full widths at half maximum of temperature and density distribution are 20 μm and 18 μm respectively.
