The proposed project seeks to investigate the dynamics of the magnetotail by using a full 3-dimensional particle in cell (PIC) simulation code. The proposed code is fully kinetic and includes all the physics contained in Maxwell's equations. The proposed research program would concentrate on the fundamental physical mechanisms of substorms. The reconnection process and current disruption process(es) that are involved in substorms are inherently not amenable to solution by MHD simulations. This proposal would therefore address an important topic that has not been addressed by any of the other GEM proposals

提出的项目旨在通过使用完整的三维粒子在细胞（PIC）模拟代码来研究磁尾的动力学。所提出的代码是完全动力学的，包括麦克斯韦方程中包含的所有物理。拟议的研究计划将集中于亚暴的基本物理机制。亚暴中涉及的重联过程和电流中断过程本质上是无法通过MHD模拟来解决的。因此，该提案将涉及其他GEM提案未涉及的重要主题
