Abstract

MHD instabilities driven by fast electrons identified as fishbonelike modes have been detected on Tore Supra during lower hybrid current drive discharges. Direct experimental evidence is reported of a novel feature: the regular redistribution of suprathermal electrons toward external tokamak regions which are correlated to periodic mode frequency jumps. Sharp drops of the electron temperature time trace are factually linked to the cyclical deterioration of the fast electron confinement.

Electron thermal transport analysis in Tokamak a Configuration Variable

Journal Article Asp, E; Porte, L; Alberti, S; ... - Physics of Plasmas

A Tokamak a Configuration Variable (TCV) [G. Tonetti, A. Heym, F. Hofmann et al., in Proceedings of the 16th Symposium on Fusion Technology, London, U.K., edited by R. Hemsworth (North-Holland, Amsterdam, 1991), p. 587] plasma with high power density (up to 8 MW/m{sup 3}) core deposited electron cyclotron resonance heating at significant plasma densities ({<=}7x10{sup 19} m{sup -3}) is analyzed for the electron thermal transport. The discharge distinguishes itself as it has four distinct high confinement mode (H-mode) phases. An Ohmic H-mode with type III edge localized modes (ELMs), which turns into a type I ELMy H-mode when the ECRHmore »« less

Sawtooth Control With ECCD On Tore Supra

Journal Article Lennholm, M; Eriksson, L; Turco, F; ... - AIP Conference Proceedings

Sawtooth control is a potentially important method for avoiding MHD instabilities triggered by sawtooth crashes, such as neoclassical tearing modes in a reactor-size tokamak. The aim of the present study is to investigate the effect of localised current drive on Sawtooth activity. In recent experiments in the Tore Supra tokamak, Electron Cyclotron Current Drive has been observed to strongly affect the Sawtooth period, even at modest ECCD power levels. For instance, with 8 MW of ICRH long, fast ion stabilised, sawteeth were shortened from 0.6 s to 0.3 s by application of 0.6 MW of co-ECCD. In these experiments itmore »« less

Wave focusing near the electron cyclotron frequency in hot plasmas

Journal Article Vezard, D; Laurent, L; Segui, J; ... - Physics of Plasmas

Microwave transmission spectra measured on the Tore Supra tokamak [Equipe Tore Supra, in {ital Proceedings} {ital of} {ital the} 12{ital th} {ital International} {ital Conference} {ital on} {ital Plasma} {ital Physics} {ital and} {ital Controlled} {ital Nuclear} {ital Fusion} {ital Research}, Nice, 1988 (International Atomic Energy Agency, Vienna, 1989), Vol. 1, p. 9] exhibit a systematic enhancement of the transmitted power at frequencies close to the electron gyrofrequency, often well beyond the corresponding level detected in vacuum.

MHD limits in non-inductive tokamak plasmas: simulations and comparison to experiments on Tore Supra

Journal Article Maget, P; Huysmans, G; Ottaviani, M; ... - AIP Conference Proceedings

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 discussing the optimal safety factor for MHD modes avoidance in Steady-State reactor plasmas. Different non-linear regimes of such magnetic configurations in Tore Supra are studied using the full MHD code XTOR. Numerical simulations show that the non-linear stage of the Double-Tearing Mode (DTM) is governed by the full reconnection model, but a single tearing mode in a low magnetic shearmore »« less

Fringe jump analysis and electronic corrections for the Tore Supra far infrared interferometer

Journal Article Gil, C; Barbuti, A; Elbeze, D; ... - Review of Scientific Instruments

On the Tore Supra tokamak, the ten-channel far infrared interferometer consists of a double color (119 and 195 {mu}m) system with two detectors for each channel to measure the plasma density. The phase measurement is obtained by combining a 100 kHz shifted reference beam with the probing beam that has crossed the plasma. The achieved precision--a few percent of a fringe--is very good compared with the expected variations due to plasma, which are on the order of several fringes. However, the counting of the fringe variations can be affected when the signal is perturbed by electromagnetic interferences or when itmore »« less
