Simulation of Neutral Beam current drive in C-2 FRC Plasmas
October 2014 | S. Gupta | APS-DPP | Poster
Recently, improved high confinement regime is observed in C2 FRC plasma due to better wall conditions and higher formation magnetic field.
Hybrid MHD Model for a Driven, Ion-Current FRC
October 2014 | H.U. Rahman | IEEE Transactions on Plasma Science | Paper
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).
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.
Transport simulations of an FRC plasma with neutral beam injection
November 2013 | M. Onofri | APS-DPP | Poster
The evolution of a Field Reversed Configuration with neutral beam injection is studied using the Q2D code.
FRC Stability Study with NIMROD and HYM Codes
November 2013 | A. Necas | APS-DPP | Poster
Gyroviscous (GV) stress for weakly magnetized plasma has been implemented in the NIMROD code to study Hall and FLR effects on FRC stability with emphasis on the rotational modes.
Neutral beam current drive in Field Reversed Configurations
November 2013 | S. Gupta | APS-DPP | Poster
The Neutral beam current drive mechanism, originally known as Ohkawa Current, is investigated for FRC plasmas using small amounts of high Z impurities.
