摘要	Abstract A radiation-driven m??=??2 island was observed in the experimental advanced superconducting tokamak (EAST) ohmic plasma, near the density limit. The mode onset occurs when the the ohmic heating input is less than the radiative cooling loss, which agrees with the mode onset behavior of the thermo-resistive model. The evolution of the equilibrium during the mode process was obtained using the ONETWO transport code, with inputs comprising the experimental electron temperature and density profiles. A large m??=??2 island can drive an m??=??1 sideband mode, which leads to an internal crash that appears as a large change in temperature that occurs not only in the q??=??2 region but also in the core.
