A dual source reflectometer for density profile and fluctuations measurements in Tore-Supra core
The stepped fixed frequency X-mode reflectometer operating between 105-160 GHz that was designed for density fluctuations measurements has been modified to measure the density profile. It runs now with two sources in parallel: a fast swept source and a frequency syntesizer to measure during the same shot the density profile and density fluctuations. Using fixed measurement, m odes in the 20-80 kHz have been detected in various plasma conditions and at various locations. TH enature of these models is still under investigation.
