Abstract :
A standard magnetohydrodynamic code, MACH2 [1], is modified in 1-D to account for two-fluid behavior, to include the effects of a finite-electric field during the formation of a driven, field-reversed configuration (FRC). The simulation is run for a period of 150 μs. Initially an azimuthal ion current is produced, then the FRC forms, compressing radially and axially, and finally the FRC decays. Previous experiments [3] agree with the simulations, specifically in the magnitude of the total current produced, including ion and electron flows, and the radial profile for the FRC, which appears to be rigid rotor [2].
