TL;DR: In this paper, electron-cyclotron-resonance heating on FTU plasmas at peak densities up to 8 keV has been shown to produce extremely high temperature gradients (up to 120 keV/m).
Journal ArticleDOI
Observation of high-frequency waves during strong tearing mode activity in FTU plasmas without fast ions
P. Buratti,P. Smeulders,Fulvio Zonca,S.V. Annibaldi,M. De Benedetti,H. Kroegler,G Regnoli,O. Tudisco +7 more
TL;DR: In this article, high frequency (HF) oscillations between 30 and 70 kHz are observed in FTU ohmic plasmas, and the presence of a threshold indicates that high frequency modes tap their energy from the tearing mode by a non-linear coupling mechanism, where the level of poloidal field perturbation produced by the island at the plasma edge exceeds 0.2%.

TL;DR: In this article, the Frascati Tokamak Upgrade (FTU) has been used to study the plasma characteristics when its limiter material is changed from the usual Inconel (nickel) to molybdenum and tungsten, and a simulation of the experimental results, made with a selfconsistent edge-core coupled model is presented, in order to provide evidence of the main physics mechanisms responsible for the observed behaviour.

TL;DR: In this paper, an analytical model that couples in a self consistent way the parameters of the SOL and the transport of the impurities generated at the limiter to the bulk plasma parameters has been used to reproduce the experimental data.
