Wavenumber spectrum of micro-turbulence in tokamak plasmas
[Spectre en nombre dʼonde de la micro-turbulence dans les plasmas de tokamak]
Comptes Rendus. Physique, Volume 12 (2011) no. 2, pp. 115-122.

Une meilleure compréhension du transport turbulent dans les plasmas de tokamak exige des comparaisons précises entre les observations expérimentales et les prédictions théoriques des caractéristiques de la micro-turbulence. La répartition de lʼénergie des fluctuations sur les différentes échelles spatiales, qui contient des informations sur le type instabilités sous-jacentes et sur les mécanismes de transfert dʼénergie entre échelles spatiales, est lʼune des rares quantités permettant une comparaison de niveau élevé. Cet article présente le travail mené sur le tokamak Tore Supra sur lʼétude du spectre en nombre dʼonde de la micro-turbulence mesuré par rétro-diffusion Doppler. Lʼapproche théorique consiste en la dérivation de modéles spectraux qui inclut les interactions entre les fluctuations et les structures dʼécoulement de grandes échelles.

A better understanding of turbulent transport in a tokamak plasma requires precise comparisons between experimental observation and theoretical prediction of micro-turbulence characteristics. The repartition of fluctuation energy over different spatial scales, which contains detailed information about the character of underlying instabilities and the mechanisms involved in energy transfer between different scales, is one of the few quantities allowing a high detail comparison. The present article reports the investigation performed on the Tore Supra tokamak on the wavenumber spectrum of micro-turbulence using Doppler backscattering. The theoretical approach consists of the derivation of spectral models that include interactions between fluctuations and large scale flow structures.
