Abstract
  • Detailed experimental studies of ion heat transport are carried out in JET to explore the T-e/T-i dependence of ion heat transport in ITER relevant range of parameters (T-e/T-i >= 1) using low rotation plasmas with dominant ion cyclotron resonance heating to avoid the coupling of the effects of T-e/T-i and rotation which affected previous experiments. This experimental setup has led to an accurate determination of the ion temperature gradient (ITG) threshold at varying T-e/T-i, offering unique opportunities for validation of the well-established theory of ITG driven modes. A rather mild decrease in threshold with increasing T-e/T-i in the interval of ITER interest was found. The new experimental result has found good agreement with theoretical predictions based on quasi-linear fluid and linear gyrokinetic models. (literal)
