Thomson scattering diagnostic utilizes a high power laser pulse to scatter photons from the plasma electrons in order to determine the plasma electron temperature and density in Doublet III. The density of the plasma is determined by the number of the photons received while the temperature is determined by their doppler shift. For the past three years, Doublet III has operated a Thomson scattering system which views two points of the plasma. Knowledge gained from this system was used in developing a second generation system which produces temperature and density profile information along a vertical axis through the upper half of the Doublet III plasma. This advanced system is presently undergoing startup testing.
