摘要
在神光Ⅲ原型装置上,利用8束激光单端驱动半腔靶实验研究了黑腔等离子体聚心时间.通过改变腔底结构建立了4种黑腔辐射源,比较了等离子体径向的聚心时间与黑腔辐射温度的变化关系.径向聚心时间和辐射温度分别由X射线分幅相机和软X射线能谱仪给出.研究发现,4种辐射源的等离子体径向聚心时间与辐射温度之间存在正比关系,聚心时间随辐射温度升高而延后。
Plasma convergence time of half-hohlraum target with single-end drive by 8 bundled lasers are researched on SG-III prototype laser facility.Four radiation sources were established by changing the structure of target bottom.The relation between plasma radial convergence time obtained by x-ray framing camera and radiation temperature from soft x-ray spectrometer have been investigated.The results showed that plasma radial convergence time is directly proportional to radiation temperatures on different structures of target bottom,which lengthens as radiation temperature increases.
