本文利用MARS-F程序,数值研究了HL-2M托卡马克装置高比压等离子体中,环向旋转对外加共振磁扰动场的响应特性的影响.研究发现,等离子体响应显著改变共振磁扰动的谱分布,并影响等离子体内部共振磁扰动场与共振磁扰动线圈电流相位差的依赖关系,从而改变有理面处径向扰动场的幅值.当边界旋转频率较小时,在最外有理面处,等离子体响应对外加共振磁扰动场有明显的放大效应.通常,边缘局域模的控制效果依赖于最外有理面处共振磁扰动场的幅度,因此可通过控制旋转剖面实现对共振磁扰动场的调控,进而优化边缘局域模的控制方案.

The type-I edge localized mode (ELM) is a critical event associated with magneto-hydrodynamic(MHD) instabilities occurring in tokamak high-confinement (H-mode) discharges, that leads to huge heat loads on the plasma phasing components (PFC) and may result in material damages. It is important to effectively control large ELMs, in order to ensure safe operation of the future reactor-scale devices such as ITER and DEMO. Resonant magnetic perturbation (RMP) has been experimentally demonstrated to be a mature and robust technique for controlling ELMs. A set of parameters, such as the edge safety fa...
