Magnetospheric Wave Particles Process

本研究旨在了解磁层等离子体波的起源及其对捕获粒子动力学行为的影响。 这将通过理论分析和数值计算来实现。 路径集成等离子体波的增长率和最终阻尼机制将在现实的模型环境中使用热射线跟踪代码进行研究。 这将建立显著的波增益和能量传递的有效性的条件，通过波，等离子体的其他组件。 将通过评估沿着特征共振扩散表面的扩散率，研究粒子在与磁层等离子体波共振相互作用期间随机加速到高能和大气中的降水损失。 提议的几个专题与正在进行的全球地磁观测系统内磁层活动有关，特别是因为它们涉及内磁层的过程和地磁暴条件。

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.
