激光等离子体中动理学阿尔芬波特性的理论研究

Theory Research of Kinetic Alfvén Waves' Properties in Laser Plasmas

激光等离子体中存在很强的自生磁场.文章利用Medusa流体力学程序分别计算了激光等离子体中Nernst效应考虑与否两种情形下该磁场的分布,并讨论了其动理学阿尔芬波(KAW)的有关特性,部分解释了已有同类实验得到不同实验结果的原因,为将来实验提供了指导.

Laser plasma has very strong spontaneous magnetic field. Medusa fluid mechanics program was used to calculate the magnetic field distribution whether considering Nernst effect or not in laser plasma,and the relative properties of Kinetic Alfvén Wave（ KAW） was discussed. This research partly explained the existing reason of similar experiments to get different results,and provided guidance for the future experiment.
