STUDY OF ANOMALOUS TRANSPORT BY AC MODULATION ON CT-6B TOKAMAK

The inward propagation equation of heat wave driven by a weak alternating modulation of the toroidal plasma curent in a tokamak plasma has been exactly solved. Based on this solution, an ac-tive method to determine the electron thermal conduction in a tokamak plasma has been proposed. The thermal conductivity is calculated as a function of minor radius From the soil X-ray data obtained in experiments on thc CT-6B Tokamak. Thc results indicate the anornalous feature of the electron thermal conduction.
