摘要

研究了非均匀随机电场作用下等离子体密度腔形成的时间演化过程。用数值方法求解了在低杂化振荡频率范围内局部随机非均匀电场作用下等离子体电子密度随时间变化的Fokker-Planck方程。得到了等离子体电子密度随时间变化的空间依赖性。

TEMPORAL EVOLUTION OF THE PLASMA DENSITY CAVITY CAUSED BY INHOMOGENEOUS STOCHASTIC ELECTRIC FIELDS

The time evolution of the formation of a plasma density cavity caused by inhomogeneous stochastic electric fields is investigated. The Fokker-Planck equation, which governs the temporal evolution of the plasma electron density due to localized stochastic inhomogeneous electric fields in the frequency range of lower hybrid oscillations, is solved numerically. The spatial dependence of the plasma electron density for various times is obtained.
