MEASUREMENT OF HEAVY IMPURITIES IN A HYDROGEN PLASMA BY CO-2 LASER LIGHT SCATTERING WITH COHERENT DETECTION
The ion feature in a plasma containing two ion components was measured with high spectral resolution using CO-2 laser scattering together with coherent detection. The laser was a pulsed hybrid system delivering 0.3 J in 1.5 mus. A ten channel spectrum analyzer allows to record a whole spectrum in one shot. The plasma source is a magnetically stabilized low-density arc (n-e approximately equal 1.5.10**15cm**-3, T-e approximately equal 2 eV). Starting with a pure hydrogen plasma other gases with atomic mass ratios up to 40 were added to simulate the effects of impurities in fusion experiments. Ion temperatures and composition were determined. In accordance with theory details in the spectra like the damping of resonances for ion mixtures were observed.
