To shed some light on the development of the fast m/n = 1/1 precursor to the sawtooth crash and its influence on plasma transport properties in the vicinity of the q = 1 surface, series of dedicated experiments have been conducted on the Tore Supra a

Non‐inductive tokamak discharges with a flat or hollow current profile are prone to the triggering of large tearing modes when the minimum of the safety factor is just below a low order rational. This issue is of particular importance for discussin

Temporal analysis and simulation of ECE spectra during LHCD in tore supra

Autor: J. L. Ségui, P Gomez, G. Giruzzi

Publikováno v: AIP Conference Proceedings.

The suprathermal electron cyclotron radiation is used to investigate fundamental phenomena governing electron tail formation during LHCD. To this end, an approximate analytical solution of the 2-D time-dependent Fokker-Planck equation is found. Elect

Measurement of the parallel distribution function during lower-hybrid current drive in Tore Supra

Publikováno v: AIP Conference Proceedings.

A transmission diagnostic system working in the frequency range 77–109 GHz has been implemented in the Tore Supra tokamak. It makes use of an ordinary mode launched along a vertical diameter, i.e., propagating along a nearly constant magnetic field
