摘要
一、测试目的与原理 激光与等离子体相互作用的大量实验说明,被吸收的激光能量向靶的临界密度层以内的输运过程是十分复杂的,热流可能被磁场所抑制,等离子体密度分布可能被等离子体非线性效应所修正。因此,采用空间分辨X光摄谱来研究这些效应是十分必要的。
This paper is a report on the spatially resolved measurements of the X-ray line radiation of laser implosion glass-microballoons,the location of the target regions where the emission of silicon X-ray lines is most dense,and the attainment of the spatial profiles of electron temperature and density at these target regions.These results are very useful for studying heat conductivity and laser nonlinear force in laser plazma.We have also deduced the optimum slit width of the X-ray spectrometer,which is very important for improving the spatial resolution of the spectrometer.
