A new method to measure power flux in strongly magnetized plasmas is described, while the flaws inherent in standard Langmuir probe techniques are demonstrated. Instead of small cylindrical pins which overestimate the ion current density by several 1

Using high-resolution diagnostics, this paper investigates experimentally two ways of influencing the radiofrequency (RF) sheath patterns (magnitude and spatial distribution) developing around active Tore Supra ion cyclotron antennae. Firstly two typ

Publikováno v: Journal of Nuclear Materials. 415:S1009-S1012

DC currents flowing along magnetic field lines connected to powered ICRF antennas have been observed experimentally. Negative current is collected on the powered ICRF antenna structure, while positive current is collected by magnetically connected La

Scaling of carbon erosion in Tore Supra

Autor: Yannick Marandet, G. Colledani, E. Tsitrone, C. Brosset, A. Beauté, M. Naiim-Habib, P. Genesio, J. P. Gunn, E. Delchambre, P. Monier-Garbet, R. Dachicourt, Yann Corre, M. Kubic, B. Pégourié, P. Börner, Detlev Reiter, T. Aniel, Eric Gauthier, A. Martinez

The scaling law for carbon erosion in Tore Supra previously established by Hogan et al. [1] (Φc(C/ s) = 5 × 1020 Pcond (MW), where Pcond is the conducted power) is revisited both from the experimental and the modelling point of view. New developmen
