The hysteresis relation between turbulence and temperature modulation during the heat pulse propagation into a magnetic island is studied for the first time in toroidal plasmas. Lissajous curves of the density fluctuation (˜n/n) and the electron temperature (Te) modulation show that the (˜n/n) propagation is faster than the heat pulse propagation near the O point of the magnetic island. This faster ˜n/n propagation is experimental evidence of the turbulence spreading from the X point to the O point of the magnetic island.
