低频turbulence磁化等离子体中径向电场引起的平行加速

Parallel acceleration due to the radial electric field in a magnetized plasma with low-frequency turbulence

Shaojie Wang

摘要:

利用Fokker-Planck相空间随机输运方程,揭示了湍流磁化等离子体平行加速的一种新的物理机制。研究发现,由于径向电场和磁矩守恒,带电粒子的随机行走与粒子平行速度的随机变化有关。这种相关性导致等离子体与有限的平行流体流的平行加速。

英文摘要:

A new physical mechanism of the parallel acceleration of a turbulent magnetized plasma is discovered by using a Fokker-Planck phase space stochastic transport equation. It is found that the random walk of a charged particle is correlated with the random change of the parallel velocity due to the radial electric field and the magnetic moment conservation. This correlation leads to a parallel acceleration of the plasma with a finite parallel fluid flow.
