Applications of light scattering and spectroscopy to plasma diagnostics. Final report, April 1, 1965--September 30, 1974

A low stored energy but large bore theta pinch and several other plasma devices served as controlled sources of impurity line radiation, or were the objects of light scattering studies with ruby and (tunable) dye lasers. The research resulted in measured values for collisional excitation and ionization rate coefficients for ions of carbon, nitrogen, oxygen, neon, argon and iron, and in some line identifications. The program also made essential contributions to a number of other diagnostic methods, notably to the measurement of turbulent electric fields by emission spectroscopy or (tunable) laser scattering, and to the cooperative light scattering on dense plasmas. Results were obtained for the ion dynamics, plasma heating and post implosion resistivity in the large bore theta pinch
