On suppressing the tearing modes in a tokamak by electron cyclotron resonance heating

Using the localization of electron cyclotron resonance heating, the profile of plasma current is improved such that the conditions of stability of tearing modes are also improved. As long as the absorbed region of electron cyclotron resonance heating covers the resonance layer of tearing modes, the effect of stabilizing is very good. It is not necessary to require that the electron cyclotron resonance surface must strictly coincide with that of the tearing mode. In the period of electron cyclotron heating, the tearing mode is effectively suppressed
