相对论逆流等离子体的一种新分布函数

A New Distribution Function for Relativistic Counterstreaming Plasmas

R. C. Tautz

摘要:

粒子分布函数,描述了两个相互渗透的等离子体流重新调查。它示出了如何,麦克斯韦-玻尔兹曼-尤特纳分布函数的基础上,已推导出近一个世纪前,逆流分布函数可以推导出,使用速度空间。这对于依赖于速度坐标而不是动量空间的各种分析计算和数值模拟是必要的。静电双流不稳定性的应用程序说明了使用相对论分布函数所造成的差异。

英文摘要:

The particle distribution function that describes two interpenetrating plasma streams is re-investigated. It is shown how, based on the Maxwell-Boltzmann-Jüttner distribution function that has been derived almost a century ago, a counterstreaming distribution function can be derived that uses velocity space. Such is necessary for various analytical calculations and numerical simulations that are reliant on velocity coordinates rather than momentum space. The application to the electrostatic two-stream instability illustrates the differences caused by the use of the relativistic distribution function.
