Description

A ruby-laser Thomson-scattering system, designed for very low--electron-density applications, has shown electron temperature (T/sub e/) and density (n/sub e/) profiles in the Elmo Bumpy Torus--Scale toroidal plasma to be flat, with T/sub e/ values from 50 to 500 eV and n/sub e/ values from 0.5 to 2.2 x 1012 cm-3. Scaling of T/sub e/ and n/sub e/ with microwave power and background pressure is discussed. Electron-energy confinement times are derived and are found to scale approximately linearly with power for times up to 4 ms
