英文摘要AbstractSawtooth crashes of large amplitude are detrimental to tokamak plasma confinement, and the amplitude has to be reduced for a fusion reactor. A novel method, i.e. applying m/n= 2/2 resonant magnetic perturbations (RMPs), is found to be able to reduce the sawtooth magnitude in J-TEXT tokamak experiments. The penetration of RMPs and formation of 2/2 locked island are found to be related to the reduction of sawtooth magnitude. With the available 2/2 RMP field, the sawtooth mitigation is reproducibly achieved with qa < 2.8 and ne < 2 × 1019 m?3 in J-TEXT.
