Electron Temperature Fluctuation Studies in Different Confinement Regimes by Means of Correlation ECE on Tore Supra
Measurements of electron temperature fluctuations aid in understanding the behaviour of the MHD phenomena and turbulent transport in fusion plasmas. On Tore Supra tokamak (R/a = 2.40 m/0.72 m, BT ??4 T, circular cross-section), first experimental observations of the electron fishbone mode in the LHCD plasmas, as well as hot ion instabilities in the combined LHCD and ICRH plasmas, have been made by means of a correlation Electron Cyclotron Emission (ECE) diagnostic. A link between the evolution of the local safety factor and the frequency of the fast hot ion mode has been investigated.
