摘 要:The kinetic effects of thermal particles and fast ions on internal kink(IK)mode are numerically investigated by the MHD-kinetic hybrid code *** is shown that either thermal particles or fast ions have stabilizing influence on ***,the former can not fully stabilize IK,and the later can suppress the *** addition,the synergistic effect from thermal particles and fast ions induces more stronger damping on *** kinetic effects from particles significantly raise the critical value of poloidal beta(βpcrit)for driving IK in the toroidal *** implies a method of controlling IK or sawtooth in the high-βp discharge scenario of *** is noted that,at the q=1 rational surface,mode structure becomes more sharp due to the self-consistent modification by particles’kinetic effect.
