本文基于OMFIT(One Modeling Framework for Integrated Tasks)平台,结合中国环流器二号M(HL-2M)托卡马克装置参数,自洽耦合等离子体平衡、外部辅助加热和电流驱动、输运等物理过程,考虑杂质浓度变化引起的等离子体密度、温度等输运量变化,以及引起的等离子体磁面中心Shafranov位移变化,从理论上进行杂质浓度变化对电子回旋波(Electron Cyclotron Wave,ECW)沉积位置和驱动电流效率的影响研究.研究结果表明,考虑杂质对等离子体的影响时,随着杂质浓度的增加,ECW沉积径向位置先向等离子体芯部移动然后向边缘移动,电流驱动效率先增加后减小.不考虑杂质对等离子体影响时,ECW沉积位置基本不变,电流驱动...

[Background] In recent years, electron cyclotron wave (ECW) heating and current drive (ECCD) have been widely used in tokamak discharge experiments. The inevitable presence of impurity particles in the tokamak plasma affects the ECCD through radiation energy, inhibition of turbulent transport, and change the collision rate. Changes in plasma density, temperature and other transport quantities caused by the change of impurity concentration, induce the changes of Shafranov displacement at the center of magnetic surface of the plasma. [Purpose] Th...
