X射线在Au等离子体中的散射截面测量

The Measurement of X-ray Scattering Cross Sections from Laser-generated Plasma

阐述了X射线在等离子体中的散射截面研究的潜在价值及对惯性约束聚变 (ICF)研究的重要意义 ,介绍了神光Ⅱ装置上的实验方案及诊断设备靶场排布。给出了该项研究的实验结果 ,并对实验结果作了初步的分析 ;给出了实验误差的主要来源 ,从获得的结果表明有望发展一种新的等离子体状态参数诊断技术。

The study of X-ray scattering cross section from laser-generated plasma is introduced, which could be used as a new diagnostics technology in inertial confinement fusion field. The results measured in ShengGuang Ⅱ facility in Shanghai, are presented. The measurement of scattering cross sections as a function of angel shows a clear peak, and the position of the peak is same with the Riley's results. The successful measurement of scattering cross section shows that the technique has potential as a probe of the laser-generated plasma.
