中低Z材料辐射烧蚀实验研究
-
摘要: 在星光Ⅱ激光装置上,利用波长为0.35μm的激光注入柱腔金箔靶产生的金箔后向X光作源,烧蚀中低Z样品材料,通过空间分辨测量靶源区和样品自发辐射X光的时间过程获得了中Z铝材料的辐射烧穿时间结果;在北京同步辐射源上对透射光栅进行了实验标定。Abstract: Intense X-ray radiation,beening used as X-ray source, has been produced from the rear of gold foil by interaction of 0.35m m laser with gold-plasma on Xingguang laser facility.Time evolution of X-ray radiation from both the X-ray source region and self-emission region of the radiation-ablated aluminium sample has been recorded by a space-resolved X-ray streak camera.
