| 摘 要： | The technique of toroidal current modulation has been successfully used in suppressing magnetohydrodynamic (MHD) perturbations effectively on the HT-7 superconducting tokamak.When the ratio of amplitude of plasma modulated current ΔIp versus the equilibrium plasma current Ipo is about 12-30%,the resonance surface is moved outside the island width,and the suppression of MHD perturbations is observed.The disruption induced by tearing mode intability is delayed or avoided.Different formats of frequency modulated are compared.
