由CME驱动的激波加速引起的太阳高能粒子（SEP）事件可以造成近地空间持续数天的高达数十MeV/n甚至GeV/n能量的灾害性粒子辐射扰动。本项目计划开发用于计算近日冕源区CME驱动的激波加速产生的SEPs的三维分布数值模式。新的模式将以三维SIP-CESE太阳风磁流体模式模拟CME驱动的激波的传播过程，并且发展波粒子相互作用自耦合处理的各向异性激波加速模式模拟种子离子的注入和加速过程。该分布模式和已开发的高能粒子在三维日球层磁场中的传播模式联合可以用于计算近地空间任意位置SEP的强度、各向异性和能谱分布，并与多卫星观测数据比较，兹以此验证该模式的可靠性和精度。该模式的开发有助于我们更深层次理解SEP在日球层中的传播和加速的物理机制，并且为下一步开发SEP事件物理预报模式奠定基础。

The solar energetic particle (SEP) events associated with CME-driven shocks can produce particles with energy of many tens MeV/n and sometimes even up to 10 GeV/n, which could last for several days and are a great concern of near-Earth space weather environment. In this investigation we start with some typical suprathermal seed particle and/or pre-accelerated particle populations. We will use focused transport model with self-consistent treatment of wave-particle interaction to model particle injection and acceleration by CME-driven shock in one step. With SIP-CESE MHD solar wind model of CME shock propagation, we can determine the spatial and temporal variation of SEP source particle at the entire interface to the interplanetary magnetic field. The model production can be inputted into 3-D SEP transport code for calculation of SEP at Earth or other locations and for comparison with observations by multiple spacecraft. With comprehensive studies of SEP acceleration and propagation, we hope to enhance our understanding to the physics of SEP events. This study is expected to lay a firm foundation for development of the physical SEP prediction model in our future research.
