Molecular Rayleigh Scattering As Calibration Method For Thomson Scattering Experiments

Abstract

This work presents the results obtained with Rayleigh scattering as method of calibration for the Thomson scattering diagnostic in the determination of density and temperature on the field-reversed theta-pinch TC-1 at UNICAMP. The methods employed to reduce the presence of stray light, as well as quest for best scattering geometry, are also described.264755759Sheffield, J., (1975) Plasma Scattering of Electromagnetic Radiation, , Academic Press, IncEvans, D.E., Katzenskein, J., (1969) Rep.
