Study of ITG modes in RFX-mod using TRB code

We present here a study about the stability of Ion-Temperature-Gradient drift turbulence in the Quasi-Single-Helicity regime of RFX-mod Reversed Field Pinch (RFP) using the TRB fluid electrostatic turbulence code. Our results suggest that present-days RFP plasmas are marginally stable against this kind of turbulence. The onset of the instability may be envisaged for close future regimes, in the presence of hotter plasmas with sharper internal transport barriers.
