| 摘 要： | 本文结合ＨＬ－１Ｍ的基本参数，利用准线性的低杂波电流驱动理论和等离子体的电回路方程．研究了在控制等离子体总电流不变情形下欧姆感应和低杂波注入组合驱动电流的问题。结果表明，这一组合驱动方案对ＨＬ－１Ｍ装置的运行是可行的，其驱动电流分布可以通过改变低杂波注入功率、波谱形状、等离子体电子温度、密度以及总等离子体电流等加以控制。组合驱动的电流分布将优于欧姆驱动的电流分布，并可能抑制诸如锯齿振荡等一些ＭＨＤ不稳定性。

| Abstract: | With the basic parameters of the HL-1M tokamak combined ohmic and lower hybid current drive(LHCD)under a constant global plasma current has been studied by using thequasilinear LHCD model and plasma circuit equation.It is shown that this prectice is feasiblefor the HL-1M device,and the driven current profile can be controlled by adjusting the LHinjecting power,power spectrum,electron density,electron temperature,global plasma current,etc.The resultant current profile will be superior to the current profile driven by eitherinduction or LHCD individually and can be controlled to improve plasma confinement and tosuppress sawtooth oscillations and some other MHD instabilities. |
