Abstract
Measurements of ion temperatures in the ATC Tokamak by means of Doppler broadening of various ion lines are described, and typical results presented for the various auxiliary heating experiments: compression, neutral beam, lower hybrid and ion cyclotron frequency heating. Radial resolution of the temperature measurements is achieved by utilizing spectrum lines of ions of different ionization potentials: OVII lambda 1623A, CV lambda 2271A and CIV lambda 1548A, which are emitted from regions of different electron temperature. Measurement at a given radial location is performed as a function of time by repeated scanning of the line contour in times 1.5 to 3.0 msec. The results indicate variations of heating efficiency with location and with power input level.
