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).

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.

Chapter 1: The FTU Program
TL;DR: The Frascati Tokamak Upgrade (FTU) has been operating for more than 12 years since its first plasma in 1990 and has played an important role in several aspects of the tokamak research as mentioned in this paper.

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.
