Study of Kinetic Relaxation to Field-Reversed Configuration using 2D PIC Simulation
A PIC simulation was performed on a configuration in which a toroidal magnetic field remains near the magnetic axis like the configuration formed by counter-helicity merging spheromaks. It was revealed that when the radius of the region with the residual toroidal magnetic field falls below the ion gyroradius, a force is generated on the electrons that moves them away from the magnetic axis, causing the toroidal magnetic field to decay and relax to a Field-Reversed Configuration (FRC).
