A multiple-point Thomson scattering device, capable of giving radial electron temperature profiles, has been developed for the ZT-40 reversed field pinch experiment. The measurement is accomplished by observing the Thomson scattered spectrum from along an entire chord of focused ruby-laser light traversing the minor diameter of the plasma. A specially built, nearly diffraction limited laser is focused through the plasma using a long focal length lens. The detector uses specially designed collection optics to focus the entire scattering volume into an image dissecting array of fiber optics, which serve as the entrance slit to an anastigmatic spectrograph. The dispersed spectra from all the spatial locations are detected with a gated microchannel plate image intensifier, and recorded on an optical multichannel analyzer using a SIT tube detector. A computer interface is used for data transmission for analysis. Results from the ZT-40 experiment will be presented.
