By adopting the Bohm type thermal diffusivity coefficient which is applicable to JET, considering the effect of the αparticle anomalous diffusion and the dynamic feedback heating, and using the energy transport equations of electron and ion, the plasma temperature profiles of deuterium-tritium (D-T) burning are studied under a given plasma density profile. Some results are obtained: the Bohm type thermal conductivity increases from the center of plasma to the boundary;in order to sustain D-T burning, the dynamic feedback heating power must be present, otherwise, the burning would be exti...
