Abstract
  • ITG modes have been found to be rarely unstable in reversed-field pinch pure-hydrogen plasmas, close to marginality only in correspondence to the transport barriers arising during single helicity states. We revisit this topic considering more realistic multi-species plasmas, to understand the possible excitement of ITG or impurity-drift instabilities. Furthermore, the back-reaction of microturbulence on the impurity transport is investigated. We present linear and nonlinear gyrokinetic simulations with the codes GS2 and HD7 (integral eigenmode equation solver), alongside with a comparison with gyrofluid 2-species nonlinear simulations.
