摘要
在“星光Ⅱ”装置上 ,采用新型双盘靶研究X射线谱在次级得到改造的特性 ,并测量出初、次级等离子体碰撞的速度 .这种双盘靶一定程度上避免了初级等离子体喷射的影响 ,可以提高烧蚀次级X射线的干净性 .采用两台软X射线谱仪分别对初级和次级辐射的X射线进行测量 ,采用X射线条纹相机测量双盘靶等离子体喷射的时空扫描图象 。
A new kind of double-disk gold targets were irradiated by 0.35 mum intense laser and the properties of improved X-ray spectra were investigated at 'Xingguang' laser facilities. Collision velocities between the primary and secondary disks' plasmas have been measured. This double-disk target's design has avoided the influence of the spraying plasma from primary disk to a certain extent, and increased the 'clearance' for ablated secondary disk. Two soft X-ray spectrometers were used to measure X-ray radiation from the primary and secondary disks, respectively. An X-ray streaked camera was used to obtain time-spactial images emitted from laser-plasma of double-disks targets. Experimental results were analyzed physically.
