Local poloidal and toroidal plasma rotation velocities and ion temperature in a tokamak plasma obtained with a matrix inversion method considering asymmetries
TL;DR: In this paper, an inversion technique is presented for the local poloidal and toroidal rotation velocities and for the ion temperature from line integrated measurements performed on Tokamak de Varennes (TdeV).

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.

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.

Wetting of a liquid surface by another immiscible liquid in microgravity
TL;DR: In this article, it was shown that, using an appropriate cell setup in order to control liquid surfaces, a liquid drop can be expanded onto and withdrawn from another immiscible liquid, which permits the measurement of the contact angle of this system.
