Description

Internal magnetic turbulence spectra have for the first time been measured directly in the Tore Supra tokamak using the Cross Polarisation Scattering (CPS) diagnostic for radial wave numbers kr around 10 cm-1. A large spectral broadening effect (2 MHz) is observed with the CPS process, and is considered to be the signature of cross polarisation scattering by the magnetic turbulence. A relative level of the magnetic fluctuations, in the range of 10-4 is deduced from the measured fluctuation spectrum. In this paper new results for this diagnostic are presented, especially the parametric dependence of the magnetic turbulence and its correlation with the energy confinement time.
