Measurement of density fluctuations and particle transport in C-2
Abstract
In the C-2 field reversed configuration experiment, long wavelength density fluctuations are measured for the first time by a newly developed far infrared (FIR) laser far forward scattering diagnostics. The dynamics of the frequency spectrum, spatial distribution, scaling with density gradient and other plasma equilibrium parameters are characterized. On the other hand, density profile evolution and particle transport are measured by the multi-chord two-color CO2/HeNe interferometer. The correlation between measured density fluctuations and particle transport will be examined.
