Description

Visible charge exchange recombination spectroscopy is routinely used to measure the time evolution of the ion temperature (Ti) and toroidal rotation velocity (vφ) profiles on TFTR. These measurements are made with the CHERS diagnostic, a fiber-optically coupled spectrometer equipped with a two-dimensional photodiode array detector which provides both spectral and spatial resolution. The instrumentation, data analysis techniques, and examples of Ti and vφ measurements are described. Recently, CHERS has been used to perform impurity transport experiments: radial profiles of diffusivities and convective velocities for helium and iron have been deduced from measurements of the time evolutions of He2+ and Fe24+ profiles following impurity injection. Examples of these measurements are given. (author). 12 refs, 8 figs
