非均匀等离子体中的动力学温度梯度驱动模

Kinetic temperature gradient driven modes in inhomogeneous plasmas

A. I. Smolyakov, M. Yagi, Y. Kishimoto

摘要:

在非均匀等离子体中发现了新的不稳定温度梯度驱动模。这些模式表示瞬态$ω\simeq k_{\Vert }v_{th}^{(e,i)}$声振荡磁化等离子体动力学不稳定,通过朗道相互作用。电子和离子的声音分支是不稳定的拉莫尔半径参数$% k_{\bot}ρ_{e,i}\gg 1,$分别大的值。不稳定性的发生是由于一个特定的等离子体响应,显着偏离玻尔兹曼分布的区域$k_{\bot}ρ_{i,e}\gg 1$。Pac:52.35 Kt,52.35 Qz

英文摘要:

New unstable temperature gradient driven modes in an inhomogeneous plasma are identified. These modes represent transient $ω\simeq k_{\Vert }v_{th}^{(e,i)}$ sound oscillations in magnetized plasma that are kinetically destabilized via Landau interactions. Electron and ion sound branches are unstable for large values of the Larmor radius parameter $% k_{\bot}ρ_{e,i}\gg 1,$ respectively. The instability occurs due to a specific plasma response that significantly deviates from Boltzmann distribution in the region $k_{\bot}ρ_{i,e}\gg 1$ . Pacs: 52.35 Kt, 52.35 Qz
