Thresholdless stochastic particle heating by a single wave
F. Sattin, D. F. Escande
Stochastic heating is a well-known mechanism through which magnetized particles may be energized by low-frequency electromagnetic waves. In its simplest version, under spatially ho…
Alfvenic propagation: a key to nonlocal effects in magnetized plasmas
F. Sattin, D. F. Escande
A long standing puzzle in fusion research comes from experiments where a sudden peripheral electron temperature perturbation is accompanied by an almost simultaneous opposite chang…
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…
Estimate of convection-diffusion coefficients from modulated perturbative experiments as an inverse problem

The estimate of coefficients of the Convection-Diffusion Equation (CDE) from experimental measurements belongs in the category of inverse problems, which are known to come with iss…
Calculation of transport coefficient profiles in modulation experiments as an inverse problem
D. F. Escande, F. Sattin
The calculation of transport profiles from experimental measurements belongs in the category of inverse problems which are known to come with issues of ill-conditioning or singular…
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…
Microturbulence studies in RFX-mod
F Sattin, S C Guo, I Predebon +3
Present-days Reversed Field Pinches (RFPs) are characterized by quasi-laminar magnetic configurations in their core, whose boundaries feature sharp internal transport barriers, in…

F. Sattin, X. Garbet, S. C. Guo
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 flu…
An Explanation From First-Principle Equations For The Universality of Non-Gaussian Distributions in Edge Plasma Fluctuations
F. Sattin
Probability Distributions Functions (PDFs) of fluctuations of plasma edge parameters are skewed curves fairly different from normal distributions, whose shape appears almost indepe…
On the statistics of edge fluctuations: comparative study between various fusion devices
F. Sattin, M. Agostini, P. Scarin +12
In this paper we present a statistical study of edge fluctuations taken with the Gas Puffing Imaging (GPI) diagnostics. We carry out a comparison of GPI signal from an extensive da…
Fick's law and Fokker-Planck Equation in inhomogeneous environments
F. Sattin
In inhomogeneous environments, the correct expression of the diffusive flux is often not given by the Fick's law . The most general hydrodynamic equation modellin…
When can Fokker-Planck Equation describe anomalous or chaotic transport?
D. F. Escande, F. Sattin
The Fokker-Planck Equation, applied to transport processes in fusion plasmas, can model several anomalous features, including uphill transport, scaling of confinement time with sys…
