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，以模拟太阳能粒子（SEP）事件电荷分布，能量光谱和相对丰度，作为由于传播的冠状质量弹出（CME）驱动的冲击而导致的空间和时间功能。该模型将移动冲击的流体动力学结合到离子动力学上，同时考虑了非平衡电荷和能量变化过程。现实主义的水平是，与SEP离子和血浆观察的自洽比较是可能的。此外，罗阿诺克学院还将建立一个专用的平行计算实验室。该实验室不仅将满足拟议模型的数值实施需求，而且还将为正在发展的平行科学计算信息技术技术中的本科科学和非科学学生提供培训。
