Description

The analysis of stabilized sawtooth oscillations in JET is presented. Spontaneous stabilization periods of about 3 seconds are observed during high power additional heating. The conditions for sawtooth stabilization are given. The evolution of the principal discharge parameters for one of the longest sawtooth - free periods obtained is discussed. The nature and cause of the sawtooth instability in tokamaks are considered. The analysis suggests that the stabilization may be due to the presence of a nonthermal ion energy distribution in the plasma
