A second-order phase transition of heat transport, which is characterized by a discontinuity in the time derivative of the temperature gradient, is observed in the high temperature plasma when the radial heat flux is modulated by repetitive pellet injections. The temperature dependence of the heat flux changes at the phase transition between two transport branches: one has a strong temperature dependence as predicted by gyro-Bohm type transport and the other has a weak temperature dependence which is consistent with the transport with the "screened" effect of zonal flow.
