Abstract

The current density distribution, and hence the q profile, remains an important unmeasured function of plasma radius. Only the total plasma current, and, in the case of sawtoothing discharges, the approximate axial current density are known. By using standard models of plasma resistivity, a current density profile can be determined by the measured electron temperature profile. A technique whereby the ECE data is used in this manner is described, together with the necessary assumptions required. Results are presented together with suggestions and warnings regarding their interpretation.
