Spontaneous m=1 instability in JET sawtooth collapseFunded under: FP2-FUSION 10C
The collapse phase of sawtooth oscillations in tokamaks is believed to be due to the rapid growth of an m=1 instability. The onset of the rapid growth is spontaneous and cannot be described by the increase of the linear growth rate arising from development of the plasma equilibrium. This result calls for a re-appraisal of the sawtooth problem.
