On the mutual effect of ion temperature gradient instabilities and impurity peaking in the reversed field pinch

I Predebon, L Carraro, C Angioni2011年Plasma Physics and Controlled FusionIF 2.2出版社

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.
