摘要
本文叙述低杂波电流驱动（ＬＨＣＤ）对ＨＬ－１Ｍ等离子体中心ＭＨＤ不稳定性［锯齿振荡（ｍ＝０），ｍ＝１模］的影响。不稳定性的振荡幅度是进入等离子体的低杂波功率的函数。当功率超过某阈值时，不稳定性被抑制，而且存在一个最佳抑制功率范围。在一定条件下，低杂波功率脉冲会激发ＭＨＤ不稳定性。
おn this paper, the effect of LHCD on the central MHD instability in the HL1M tokamak is described. The modeamplitudes for sawteeth m=0 and m=1 are a function of the LHW power. The instabilities are suppressed when sufficient LHW power is launched into the plasma, and there is an optimum power range for suppression of the instabilities. It is observed that the central MHD instability can be excited under certain conditions.
