Microtearing Modes in Reversed Field Pinch Plasmas
I. Predebon, F. Sattin, M. Veranda +2
In the reversed field pinch RFX-mod strong electron temperature gradients develop when the Single-Helical-Axis regime is achieved. Gyrokinetic calculations show that in the region…
Faraday shield dissipation in the drivers of SPIDER based on electromagnetic 3D calculations
D. López-Bruna, S. Denizeau, I. Predebon +3
SPIDER (Source for the Production of Ions of Deuterium Extracted from Rf plasma) is a full-scale prototype of the ITER NBI source. It is based on the concept of inductive coupling…
Modelling of impurity heating during reconnections in a Reverse Field Pinch device as due to parallel electric field acceleration and chaos-induced thermalization
F. Sattin, D. F. Escande, M. Gobbin +1
The ion temperature during magnetic reconnections measured along the direction of the magnetic field at the MST Reverse Field Pinch has not yet received a satisfactory theoretical…
The effect of toroidicity on relaxed states at low aspect ratio
R. Paccagnella, S. Masamune, I. Predebon +1
The experimentally measured single helical states in the low aspect ratio (R/a=2) RELAX device have been compared with the predictions of a cylindrical relaxation theory and a subs…
Ion temperature gradient turbulence in helical and axisymmetric RFP plasmas
I. Predebon, P. Xanthopoulos
Turbulence induced by the ion temperature gradient (ITG) is investigated in the helical and axisymmetric plasma states of a reversed field pinch device by means of gyrokinetic calc…
Two-fluid boundary turbulence simulations in reversed field pinch plasmas
M. Giacomin, B. Momo, I. Predebon +2
Turbulent transport in magnetic confinement fusion devices governs the overall plasma confinement properties and regulates the plasma-material interaction at the first wall. In the…
Outside and inside a magnetic island: different perspectives to describe the same observables
B. Momo, I. Predebon
We compare three different approaches to describe a magnetic island in a generic toroidal plasma: (i) perturbative, from the perspective of the equilibrium magnetic field and the r…
On the linear stability of collisionless microtearing modes
I. Predebon, F. Sattin
Microtearing modes are an important drive of turbulent heat transport in present-day fusion plasmas. We investigate their linear stability under very-low collisionality regimes, ex…
On the mutual effect of ion temperature gradient instabilities and impurity peaking in the reversed field pinch
I. Predebon, L. Carraro, C. Angioni
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…
