RAHMAN et al.: HYBRID MHD MODEL FOR A DRIVEN, ION-CURRENT FRC 3139
Fig. 1. Left: contours of total pressure with the normalized magnetic field vectors at 50, 100, and 150 μs. Right: line-outs of normalized pressure P and the axial component of magnetic field Bz versus r at z = 0.
The results of the simulation are presented in Figs. 1–3. Fig. 1 shows the plasma pressure, along with the normalized- magnetic-field vectors, at 50, 100, and 150 μs, corresponding to the formation, evolution, and equilibrium of the FRC.
The current is initially due to the azimuthal flow of ions. Field reversal starts as early as 10 μs and the applied-magnetic field is completely reversed by 40 μs when an oblate FRC plasma is established. The plasma then begins to compress
