Recently, a new propulsion system called Magneto Plasma Sail (MPS) attracts the attention, and it is expected to have high thrust power ratio and specific impulse. The MPS produces the propulsive force by interaction between the solar wind and the artificial magnetic field inflated by the plasma injection. This research and development memorandum shows a detail description of the Hybrid (ion particles, electron Fluid) code for the research and development of the MPS. A discretization procedure for a total variation diminishing (TVD) scheme is introduced to the Hybrid code in order to improve the numerical stability and resolution when calculating the plasma flow field in which magnetic field discontinuities (for example, Rankine-Hugoniot jump conditions for shock waves) are generated. The TVD scheme significantly prevents non-physical, numerical oscillations, which would ordinarily be produced in the solution when the convection term of the magnetic induction equation in the Hybrid code is discretized by central difference schemes at magnetic field discontinuities. Also, the typical simulation results using 2D or 3D Hybrid code developed for the present research are reviewed.
