ELECTRIC FIELD PROFILE IN PRESENCE OF SAWTOOTH ACTIVITY IN A TOKAMAK
The two coupled diffusive equations for the perturbed electron temperature and poloidal magnetic field are solved in the framework of the Kadomtsev model for the sawtooth activity. It is found that the time averaged toroidal electric field profile is radially non-uniform. A simple formula which describes the radial behaviour of the toroidal electric field is proposed, and the effect on the power balance is presented.
