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.

Experimentally measured inverted core density fluctuations spectra show the absence of ion-scale modes in the FRC core, in agreement with linear, local gyrokinetic simulations.
