| 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.

| Abstract: | 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. |
