A two-dimensional Thomson scattering system is being designed for the Advanced Toroidal Facility (ATF) torsatron experiment. This system will provide electron temperature and density measurements at 15 points along a vertical chord with each shot from a two-dimensional T-italic/sub e-italic/ and n-italic/sub e-italic/ map of an ATF toroidal cross section can be obtained. The horizontal Thomson scattering viewing port is offset by 15/sup 0/ toriodally from the ports passing the vertical laser beam. Translating and rotating mirors will be used to relay light from the viewing port to the collection lens. This makes it possible to scan horizontally, view as much of the vertical laser beam as possible, and to use a fixed focal length, fixed position lens. Three sets of spectrometers optimized to three temperature ranges will be used. At the output of each spectrometer, dispersed light will be detected by an array of five, seven, or eight photomultiplier tubes, depending on the temperature range of the spectrometer.
