Experimental measurements of electron thermal condouctivity coefficient on the CT-6B device are reported here. With the help of MHD internal disruption, which specifies the temperature sawtooth perturbation, analysing the amplitudes, cycles and phases of the perturbation signals of soft x-ray detectors, we have calculated the average electron thermal coefficients in different radiuses. Experiment results are an order of magnitude larger than that predicted by neoclassical theory, showing that electron heat conductivity in the CT-6B plasma is an anomalous one. It is shown that MHD internal disruption can make the energy transport increases obviously. Electron heat conductivity increases with the amplitude of MHD perturbo-tion.
