Flux amplification of a field-reversed configuration by double-sided plasmoid injection

Trapped magnetic flux in a field-reversed configuration (FRC) plasma was amplified by double-sided magnetized plasmoid injection. Since the magnetic energy in plasmoids was much less than that in the FRC, the FRC's magnetic flux was presumed to be enhanced by the increased diamagnetic current. The plasmoids supplied particles to the FRC from the both ends and increased the peak pressure as well as the pressure gradient in the vicinity of the separatrix.
