GEM: Modeling Energetic Particle Injections During Geomagnetic Storms and Magnetic Substorms

研究高能粒子注入（电子50keV，离子100kev）与地磁风暴和亚风暴的关系，试图了解在这些事件中尾磁层和内磁层的磁场和电场的变化。研究将集中在与孤立的亚暴相关的脉冲注入以及在磁层内部观测到的由此产生的漂移回波。漂移回波可以提供磁场和电场在时间和空间上的变化信息，这些信息可以用于控制粒子运动的场的模型。将使用测试粒子跟踪技术，并将模拟结果与观测结果进行比较。

This proposal is to investigate energetic particle injections (electrons 50keV,ions 100 keV) associated with geomagnetic storms and substorms in an attempt to understand the change of the magnetic and electric fields in the tail and inner magnetosphere during these events. Investigations will focus upon impulsive injections associated with isolated substorms and the resulting drift echoes observed in the inner magnetosphere. Drift echoes can provide information about changes in the magnetic and electric fields in both time and space, which can be utilized in models of the fields that govern the particle motions. Test particle tracing techniques will be utilized and the simulation results will be compared with observations.
