On the mutual effect of ion temperature gradient instabilities and impurity peaking in the reversed field pinch
Published 21 Oct 2011 in physics.plasm-ph | (1110.4815v1)
Abstract: The presence of impurities is considered in gyrokinetic calculations of ion temperature gradient (ITG) instabilities and turbulence in the reversed field pinch device RFX-mod. This device usually exhibits hollow Carbon/Oxygen profiles, peaked in the outer core region. We describe the role of the impurities in ITG mode destabilization, and analyze whether ITG turbulence is compatible with their experimental gradients.
