在laser辐照的稠密等离子体中韦伯不稳定性介导的无碰撞激波:电子在turbulence产生中的主要作用

Weibel instability-mediated collisionless shocks in laser-irradiated dense plasmas:Prevailing role of the electrons in the turbulence generation

C. Ruyer, L. Gremillet, G. Bonnaud

摘要:

本文采用粒子模拟方法研究了超高强度激光脉冲驱动下稠密等离子体中无碰撞湍流激波的产生。从线性分析中,我们强调了激光加热和返回电流电子在触发强烈的韦伯不稳定性中的关键作用,从而产生能够各向同性靶离子的磁湍流。

英文摘要:

We present a particle-in-cell simulation of the generation of a collisionless turbulent shock in a dense plasma driven by an ultra-high-intensity laser pulse. From the linear analysis, we highlight the crucial role of the laser-heated and return-current electrons in triggering a strong Weibel-like instability, giving rise to a magnetic turbulence able to isotropize the target ions.
