Various divertor biasing configurations and improved divertor performance with biasing on Tokamak de Varennes (TdeV)
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 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.

Characterization of diffused ECR plasma—Application to pulsed plasma ion implantation of nitrogen in titanium
TL;DR: In this article, a surface electron cyclotron resonance (ECR) plasma source, developed at the Institut National de la Recherche Scientifique (INRS)-Energie et Materiaux, has been used as a versatile surface treatment tool.

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.

Improvements in recycling and impurity control obtained by divertor biasing
B. Terreault,Barry L. Stansfield,J.-L. Lachambre,R. Décoste,B.C. Gregory,E. Haddad,C. Janicki,C. Liu-Hinz,D. Michaud,A. Sarkissian,W. Zuzak,C. Boucher,A. Côté,F. Martin,H.H. Mai,Guy G. Ross,M. St-Onge,Dennis Whyte +17 more
TL;DR: In this paper, a comprehensive set of diagnostics was used and those effects relating to plasma-surface interactions and their consequences, namely recycling and impurity production, were reported in the Tokamak de Varennes, with ohmic discharges and boronized walls.
