This project will perform a systematic investigation of the entry of solar wind ions into the magnetosphere. Particles will be followed from the solar wind, through the magnetopause, and then into the various regions of the magnetosphere. It will determine whether there are mechanisms other than magnetic reconnection that allow a significant number of ions access to the magnetosphere and will also address the question of what contribution the ionosphere makes to the ion population. The project will utilize the results from prior MHD modeling of the magnetosphere to define the state of the magnetosphere and then will utilize a test-particle tracing technique to follow ions from the solar wind into the magnetosphere

该项目将对太阳风离子进入磁层的情况进行系统调查。 粒子将跟随太阳风，穿过磁层顶，然后进入磁层的各个区域。 它将确定是否存在磁重联以外的机制，使大量离子进入磁层，还将解决电离层对离子总数有何贡献的问题。 该项目将利用先前磁层MHD建模的结果来确定磁层的状态，然后将利用测试粒子跟踪技术跟踪太阳风中的离子进入磁层
