Numerical and analytic models will be used to study the sources of shock-accelerated energetic particles in the near-Earth region. A critical component of this investigation is the interpretation of data obtained from a variety of spacecraft such as ACE, WIND, and ULYSSES. The first task will address the recent popular idea that remnant material from impulsive solar flares may provide a source of seed particles for injection into large CME-associated events. These particles can be recycled, or further accelerated by propagating transient shocks, or perhaps those associated with corotating interaction regions. The validation of this concept hinges upon a demonstration that the seed particles can be effectively transported from the compact flare site to the extended shock fronts. The second task is to look at how low-energy ions are accelerated by shocks, and to determine what fraction of the thermal particles swept into the shock can be injected into the acceleration process.

数值和分析模型将用于研究近地区域中休克加速能量颗粒的来源。 这项研究的关键组成部分是对从各种航天器（例如ACE，Wind和Ulysses）获得的数据的解释。 第一个任务将解决最近的流行思想，即冲动太阳耀斑的残留物质可能会为向大型CME相关事件注入的种子颗粒来源。 这些颗粒可以通过传播瞬态冲击或可能与旋转相互作用区域相关的颗粒进行回收，也可以进一步加速。 该概念的验证取决于证明种子颗粒可以有效地从紧凑型耀斑位点传输到扩展的冲击锋。 第二个任务是查看电击的低能离子加速度的加速度，并确定可以将扫除冲击的热颗粒的哪一部分注入加速过程中。
