Nonlinear Tearing Modes in Current-Vortex Sheets
D. Urbanski, F. L. Waelbroeck, A. Tenerani
The linear and nonlinear development of instabilities and Alfvén resonances in a plane current-vortex sheet is presented here for sheared equilibrium profiles $\boldsymbol{B_{y0}}…

X point effects on the ideal MHD modes in tokamaks in the description of dual-poloidal-region safety factor
Linjin Zheng, M. T. Kotschenreuther, F. L. Waelbroeck +1
The flux coordinates with dual-region safety factor (q) in the poloidal direction are developed in this work. The X-point effects on the ideal MHD modes in tokamaks are then analyz…

Unified Framework of Forced Magnetic Reconnection and Alfven Resonance
D. Urbanski, A. Tenerani, F. L. Waelbroeck
A unified linear theory that includes forced reconnection as a particular case of Alfvén resonance is presented. We consider a generalized Taylor problem in which a sheared magnet…
