First measurements of electron temperature fluctuations by correlation ECE on Tore Supra
Electron Temparature fluctuation studies can help to understand the nature of the turbulent transport in tokamak plasmas. At Tore Supra a 32-channel heterodyne ECE radiometer has been upgraded with two channels of 100 MHz bandwidth and tunable central frequencies allowing the shift of the plasma sample volume in the radial direction. With the sufficiently large video bandwidth and the long sampling time, it is possible to reduce significantly the thermal noise and to identify �true� high frequency components up to 200 kHz from the cross-correlation between these channels. First results of temperature fluctuation measurements on Tore Supra are reported in this paper.
