用数值模拟研究用高功率强激光驱动柱压缩产生温度密度梯度低的高温高密度等离子体的可能性 ,研究了可能获得的高温高密度等离子体状态的范围 ,并估计了此类靶中 Rayleigh-Taylor不稳定性和 Richtmyer-Meshkov不稳定性产生的危害程度。结果表明柱压缩可以产生比较均匀的等离子体状态 ,可以用于辐射不透明度的实验测量。
The possibility of high-temperature and high-density plasma with low temperature density gradient was driven by high-power and intense laser-driven column compression by numerical simulation. The range of possible high-temperature and high-density plasma states was investigated. The Rayleigh- Taylor instability and Richtmyer-Meshkov instability. The results show that column compression can produce a more uniform plasma state, which can be used for experimental measurement of radiation opacity.
