Electron internal transport barriers (eITBs) are obtained in TCV with different heating and current drive schemes. They are sustained in steady-state conditions for several energy confinement and current redistribution times. In these scenarios, the densit ...

Studies of high frequency hot ion instabilities by means of correlation ECE on Tore Supra

Timothy Goodman, Henri Weisen

High frequency (> 100 kHz) modes have been observed for the first time in combined LHCD and ICR-heated minority H (D) plasmas on Tore Supra by means of a correlation ECE diagnostic and by fluctuation reflectometers. These modes have been identified as the ...

High-bootstrap, noninductively sustained electron internal transport barriers in the Tokamak a Configuration Variable

Roland Behn, Timothy Goodman, Olivier Sauter, Stefano Coda, Andrei Martynov, Petri Nikkola, Alberto Bottino, Andrea Scarabosio, Yann Camenen, Emiliano Fable, Costanza Zucca

Important ingredients of the advanced-tokamak route to fusion have been explored in depth in the Tokamak a Configuration Variable [F. Hofmann, J. B. Lister, M. Anton , Plasma Phys. Controlled Fusion 36, B277 (1994)] over the past two years. Using a uniquel ...

Inductive current density perturbations to probe electron internal transport barriers in tokamaks

Roland Behn, Timothy Goodman, Olivier Sauter, Stefano Coda, Andrei Martynov, Petri Nikkola, Alberto Bottino, Emiliano Fable, Costanza Zucca

Improved electron energy confinement in tokamak plasmas, related to internal transport barriers, has been linked to nonmonotonic current density profiles. This is difficult to prove experimentally since usually the current profiles evolve continuously and ...
