Sawtooth-Control Mechanism using Toroidally Propagating Ion-Cyclotron-ResonanceWaves in Tokamaks

The sawtooth control mechanism in plasmas employing off-axis toroidally propagating ion cyclotron resonance waves in tokamaks is reinvestigated. The radial drift excursion of energetic passing ions distributed asymmetrically in the velocity parallel to the magnetic field determines stability when the rational q = 1 surface resides within a narrow region centered about the shifted fundamental cyclotron resonance.
