Abstract
The localized electron cyclotron resonance heating power that can suppress
sawteeth reconnection often drives m = 2 tearing modes in a tokamak operati
ng at constant current. The dynamics of mode onset and coupled mode evoluti
on is described in detail and compared with a nonlinenr theoretical model t
hat identifies the effects of mode coupling, finite inertia of the rotating
islands, and wall braking.
