要約(英語): Translation motion of a field-reversed configuration (FRC) plasma caused by the magnetic pressure gradient force is simulated by the 2-D resistive MHD simulation model. In the MHD code, we modeled to separate the external magnetic field and the field generated by the plasma. The translation velocity is controlled by a time-varying external magnetic field, and the volume-averaged translation velocity in our case is found to reach about 60% of the Alfven velocity estimated by the external field and the maximum density. Axial collision processes of two FRC plasmas are also studied, and it is found that the current density at their midpoint increases rapidly when two FRCs get close to each other.
