Description
Two-dimensional MHD simulations are carried out which demonstrate that the cross-field thermal conduction near the magnetic axis controls the structure of sawteeth in tokamaks. In simulations of discharges with good central confinement, skin currents form at a finite radius causing the safety factor q to fall below 1 away from the magnetic axis. Both normal and compound sawteeth are produced which have many features consistent with experimental observations
