AbstractMagneto Plasma Sail (MPS) is proposed as one of the innovative interplanetary flight systems. The propulsion of MPS is obtained as a result of multi-scale kinetic interactions between the solar wind plasma and a small-scale artificial magnetosphere created around the spacecraft. In the investigation of the multi-scale plasma interactions in association with MPS, plasma particle simulation can be a powerful tool. However, it is difficult to handle the multi-scale phenomena with the conventional particle simulation which adopts uniform spatial grid system. To conquer this difficulty we will establish the foundation and the methodology for the multi-scale plasma particle simulations by combining Adaptive Mesh Refinement (AMR) and Particle-In-Cell (PIC) methods. In the new AMR-PIC code, we introduced the fully threaded tree (FTT) structure for the AMR scheme. In the FTT, a hierarchical grid system is maintained all by pointers and each cell is treated as an independent unit organized in a refinement tree structure rather than conventional element of arrays. Each particle also has a pointer for the next particle located in the same cell. In the parallelization of the code, we adopt domain-decomposition and assign each sub-domain to each processor. To keep the load balancing between processors, the partitioning of sub-domains is done by using the Morton ordering method which is one of the space filling curves. We modified the method so that the load of the particle calculation is considered in the sub-domain partitioning. In parallel to the tool development, we focus on the quantitative evaluation of the MPS thrust by performing Particle-In-Cell(PIC) simulations in which plasma kinetics are included. We will show some preliminary results on the magnetic field inflation by plasma injection from the spacecraft which is necessary to obtain the larger interaction area with the solar wind.
