Dependence of the L–H transition on separatrix-wall gaps on TdeV

Autor: C. Côté, N. Richard, B. Quirion, J.-L. Lachambre, Y. Demers, TdeV Team, G.W. Pacher, C. Boucher, D. Pinsonneault, D. Lafrance, M St.-Onge, A. Côté, R. Décoste, J.-L. Gauvreau

Publikováno v: Journal of Nuclear Materials. :911-916

Steady-state H-modes have been obtained on TdeV both with ECRH and Lower Hybrid heating. Power thresholds are comparable with those predicted by the ITER scaling laws. A very pronounced threshold in edge density is observed, below which no L–H tran

Divertor helium pumping in TdeV-96 under various conditions

Autor: J.-L. Gauvreau, C. Côté, Barry L. Stansfield, Y. Demers, G.W. Pacher, TdeV Team, J.-L. Lachambre, G. Lebrun, N. Richard, R. Décoste

Publikováno v: Journal of Nuclear Materials. :307-311

In this paper, we report on the effects of density, divertor geometry and ECRH heating on divertor pressure and helium enrichment. Low, medium and high (semi-detached) densities were investigated with outboard pumping (OB) and private region pumping

Kinetic modeling of the transport in the SOL of TdeV during LH current drive and ELM bursts

Autor: I. Shkarofsky, D. J. Sigmar, R. Décoste, A. A. Batishcheva, M. Shoucri, G.W. Pacher, J.-L. Gauvreau, P. Jacquet, Oleg Batishchev

Publikováno v: Journal of Nuclear Materials. :1202-1206

Fully kinetic plasma–neutrals Fokker–Planck code ALLA is used to simulate the transport properties of the scrape-off layer (SOL) plasmas of Tokamak-de-Varennes during lower hybrid (LH) current drive and edge localized modes (ELM) bursts. During L

Experimental demonstration of tokamak fuelling by compact toroid injection

Publikováno v: Nuclear Fusion. 37:967-972

The most promising concept for deep fuelling a reactor is by the injection of compact toroid (CT) plasmoids. The first results showing CT fuelling of a tokamak plasma, without any adverse perturbation to the tokamak discharge, are reported. The Compa

Controlled detachment and particle transport in the divertor plasma in TdeV

Publikováno v: Journal of Nuclear Materials. :739-744

At high densities, the plasma detaches from the outboard divertor plates in TdeV. The signatures are a reduction of the ion flux to the divertor plate, movement of the radiating zone from the plate toward the X-point, a pressure gradient between an i

Characterization and control of the power loss and its distribution in TdeV during divertor plate biasing experiments

Autor: A. Sarkissian, J.-L. Lachambre, A. Côté, B. Terreault, J. Mailloux, Barry L. Stansfield, T. Fall, R. Décoste, B.C. Gregory, H.Y. Guo, W. Zuzak, J. P. Gunn, F. Meo, N. Richard, Richard Marchand, C. Boucher

Publikováno v: Nuclear Fusion. 35:641-649

Effective control of the particle and power flux distributions between the upper and lower divertors has been demonstrated on TdeV, using biasing of the divertor plates, in ohmic discharges with a double null magnetic configuration. Negative biasing
