ECE measurement using Doppler shifted observations on Tore Supra
Information on the electron distribution function is essential for understanding current drive experiments. For this purpose, a new configuration of ECE measurements has been tested on Tore Supra. The radiated spectrum is measured simultaneously with three absolutely calibrated Michelson interferometers. The lines of sight are located in the equatorial plane in normal co- and counter-directions (+/- 11 ). The first spectra were obtained recently during ohmic and non-thermal shots. Frequency Doppler shift is used in the case of oblique lines of sight to investigate the signature of asymmetry in the distribution function of the electrons. Differences are found between spectra in all cases and are compared with theoretical expectations.
