【摘要】 本文利用高空间分辨的X射线针孔相机、晶体谱仪和光探针从三维空间上探测激光辐照平面靶产生的等离子体高、低阶电离离子的分布,发现高、低阶离子所占据的空间都具有近似的圆锥形状态,但它们重迭且方向相反。本文也得到了等离子体中离子密度在空间上的两种分布结构。更多还原

【Abstract】 Using X-ray crystal spectrograph, light probing and X-ray pin-hole camera, we have measured the distributions of high and low ionizing ions of plasma in the three-dimensional space. We have found the spaces in which the high and low ionizing ions occupied were of conical forms, but overlapped each other and the directions of the cones were opposite. in addition, we have also obtained two distrbutions of ion densities.更多还原
