CHARACTERIZATION OF THE C-2W PLASMA GUNS
October 2017 | Ami M. Dubois | APS-DPP | Poster
Previous use of coaxial arc discharge plasma guns on the C-2U device exhibited great success in plasma stabilization and improved confinement.
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
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.
Achievement of Sustained Net Plasma Heating in a Fusion Experiment with the Optometrist Algorithm
July 2017 | E. A. Baltz | Scientific Reports | Paper
TAE and Google have partnered to combine human and machine interaction to further plasma science using their “Optometrist Algorithm.”
Compact Toroid Injection Fueling in a Large Field-Reversed Configuration
May 2017 | T. Asai | Nuclear Fusion | Paper
A repetitively driven compact toroid (CT) injector has been developed for the large eld- reversed con guration (FRC) facility of the C-2/C-2U, primarily for particle refueling. A CT is formed and injected by a magnetized coaxial plasma gun (MCPG) exclusively developed for the C-2/C-2U FRC.
Development of a First-Principles Simulation Model of Turbulent Transport in Compact Tori
May 2017 | D.P. Fulton | The Sherwood Fusion Theory Conference | Poster
FRC core strongly stable! Finite SOL turbulence. Both FLR and gradient-B effects stabilizing. Qualitative agreement with measure doppler backscattering.
