A numerical model will be developed to simulate solar energetic particle (SEP) event charge distributions, energy spectra, and relative abundances as functions of space and time due to a propagating coronal mass ejection (CME) driven shock. This model couples the hydrodynamics of the moving shock to the ion kinetics, while at the same time accounting for non-equilibrium charge and energy change processes. The level of realism is such that self-consistent comparisons with SEP ion and plasma observations will be possible. In addition, a dedicated parallel computing laboratory will be established at Roanoke College. This laboratory will not only address the needs for numerical implementation of the proposed model, but it will also provide training for undergraduate science and non-science students in the developing information technology art of parallel scientific computing.

将开发一个数值模型来模拟太阳高能粒子（SEP）事件电荷分布、能谱和相对丰度作为空间和时间的函数，这是由于传播日冕物质抛射（CME）驱动的激波。该模型将运动激波的流体动力学与离子动力学耦合在一起，同时考虑了非平衡电荷和能量变化过程。现实的水平是这样的，与SEP离子和等离子体观测的自我一致的比较将是可能的。此外，将在罗阿诺克学院建立一个专门的并行计算实验室。该实验室不仅将满足所提出模型的数值实现需求，而且还将为本科理科和非理科学生提供并行科学计算发展信息技术艺术的培训。
