Abstract: Based on neutral beam injection heating and electron cyclotron resonance heating, a general dispersion relation for fishbone-like internal kink mode was obtained when the spatial density profile of fast particle in Tokamak plasma was taken into account. The numerical results show that the internal kink mode can be stabilized by fast particles and high frequency fishbone mode can be triggered by fast particles in the case of near-axis heating. The real frequency of the mode is poroportional to the averaged toroidal precession frequency of fast particles. The growth rate of the mode depends on density gradient of fast particles and increases with density gradient. The fishbone mode can be driven into the second stable regime by barely passing fast particles and becomes stable in high specific pressure region.
