Magnetohydrodynamic transport characterization of a Field Reversed Configuration

Magnetohydrodynamic transport characterization of a Field Reversed Configuration

September 2017 | M. Onofri | Physics of Plasmas | Paper

The transport phenomenon of a Field Reversed Configuration (FRC) is studied using the newly developed two-dimensional code Q2D, which couples a magnetohydrodynamic code with a Monte Carlo code for the beam component. The simulation by Q2D of the transport parallel to the simple open h-pinch fields and its associated outflow phenomenon shows an excellent agreement with one of the leading theories, elevating the Q2D validity and simultaneously deepening the theoretical understanding of this fundamental process.

Drift-wave stability in the field-reversed configuration

Drift-wave stability in the field-reversed configuration

August 2017 | C. K. Lau | Physics of Plasmas | Paper

Gyrokinetic simulations of C-2-like field-reversed configuration (FRC) find that electrostatic drift- waves are locally stable in the core. The stabilization mechanisms include finite Larmor radius effects, magnetic well (negative grad-B), and fast electron short circuit effects.
