A One-Dimensional Tearing Mode Equation for Pedestal Stability Studies in Tokamaks
J. W. Connor, R. J. Hastie, C. Marchetto +1
Starting from expressions in Connor et al. (1988) [1], we derive a one-dimensional tearing equation similar to the approximate equation obtained by Hegna and Callen (1984) [2] and…
Collisionless microinstabilities in stellarators. IV. The ion-driven trapped-electron mode
G. G. Plunk, J. W. Connor, P. Helander
Optimised stellarators and other magnetic-confinement devices having the property that the average magnetic curvature is favourable for all particle orbits are called maximum- d…
Gyrokinetic stability theory of electron-positron plasmas
Per Helander, J. W. Connor
The linear gyrokinetic stability properties of magnetically confined electron-positron plasmas are investigated in the parameter regime most likely to be relevant for the first lab…
Magnetic compressibility and ion-temperature-gradient-driven microinstabilities in magnetically confined plasmas
A. Zocco, P. Helander, J. W. Connor
The electromagnetic theory of the strongly driven ion-temperature-gradient (ITG) instability in magnetically confined toroidal plasmas is developed. Stabilizing and destabilizing e…
Ion Landau Damping on Drift Tearing Modes
J. W. Connor, R. J. Hastie, A. Zocco
Kinetic treatments of drift-tearing modes that match an inner resonant layer solution to an external MHD region solution, characterised by , fail to properly match the…
