Hybrid magneto-hydrodynamic simulation of a driven FRC

June 2014 | H.U. Rahman | Physics of Plasmas | Paper

We simulate a field-reversed configuration (FRC), produced by an “inductively driven” FRC experiment; comprised of a central-flux coil and exterior-limiter coil. To account for the plasma kinetic behavior, a standard 2-dimensional magneto-hydrodynamic code is modified to preserve the azimuthal, two-fluid behavior.

Rotational stability a long field-reversed configuration

February 2014 | D. Barnes | Physics of Plasmas | Paper

Rotationally driven modes of long systems with dominantly axial magnetic field are considered. We apply the incompressible model and order axial wavenumber small. A recently developed gyro-viscous model is incorporated. A one-dimensional equilibrium is assumed, but radial profiles are arbitrary.
