要約(英語): The two-dimensional resistive MHD simulation is carried out to find the mechanism of flux lifetime extension by means of axial neutral gas flow injection; it is thought as a process equivalent to FRC translation into a region where neutral gas is filled. We have derived the MHD equations with the source terms due to ionization of neutral particles. Extension of the flux lifetime has been found and its increment rate increases with the injection energy. We have investigated the flux variation calculated from the Faraday's law, and found that the inductive electric field due to the Lorentz force is a dominant reason for lifetime extension.
