Magnetospheric Wave Particles Process

本研究旨在了解磁层等离子体波的起源及其对被困粒子动力学行为的影响。这将通过理论分析和数值计算来完成。利用热射线跟踪代码，研究了等离子体波在真实模型环境下的路径集成增长率和最终阻尼机制。这将为显著的波增益和能量传输的有效性建立条件，通过波，到等离子体的其他组成部分。在与磁层等离子体波共振相互作用过程中，粒子向高能的随机加速和向大气的降水损失将通过计算沿特征共振扩散面的扩散速率来研究。提出的几个主题与正在进行的GEM内磁层运动有关，特别是因为它们涉及内磁层和地磁风暴条件下的过程。

This research seeks an understanding of the origin of magnetospheric plasma waves and their influence on the dynamical behavior of trapped particles. This will be accomplished through theoretical analysis and numerical computation. The path integrated growth rate and ultimate damping mechanisms for plasma waves will be studied in realistic model environments using the HOT RAY tracing code. This will establish the conditions for significant wave gain and the effectiveness of energy transfer, via the waves, to other components of the plasma. The stochastic acceleration of particles to high energy and precipitation loss to the atmosphere during resonant interaction with magnetospheric plasma waves will be studied by evaluating the rate of diffusion along the characteristic resonant diffusion surfaces. Several of the proposed topics are relevant to the ongoing GEM inner magnetosphere campaign, particularly as they address processes in the inner magnetosphere and geomagnetic storm conditions.
