R. Décoste,J.-L. Lachambre,G. Abel,A. Boileau,C. Boucher,A. Côté,T. Fall,J.-L. Gauvreau,B.C. Gregory,E. Haddad,C. Janicki,C. Liu-Hinz,H. H. Mai,François Martin,D. Michaud,N. Richard,G.G. Ross,A. Sarkissian,Barry L. Stansfield,B. Terreault,W. Zuzak +20 more
TL;DR: In this paper, a radial electric field Er in the scrape-off layer (SOL) is produced with a particular divertor plate geometry, causing a nonambipolar radial current and a particle flow in the Er×BT direction, toward one of the diverors (the active divertor).

TL;DR: In this article, a simple model based on non-ambipolar radial transport and planar sheath physics is used to describe the generation of radial electric fields and currents in the scape-off layer of the TdeV during divertor plate biasing.

TL;DR: In this paper, bias voltages applied to the divertor plates in TdeV (Tokamak de Varennes) permit fine control of several main plasma parameters, including the poloidal rotation velocity near the separatrix, microturbulence, the sawtooth period and the heat pulse propagation speed.

TL;DR: In this article, the effect of bias voltage on the drift direction of the electron diamagnetic drift has been investigated and it is shown that the drift is in the direction of 2-3 km/s and increases by a factor of two for Vbias = 100 V.

TL;DR: In this paper, solid target boronization (STB) and TMB fuelling were used as fuelling gas during the plasma discharge to improve the volume averaged resistivity and radiated power.
