| 摘 要： | 采用1.5维的放电模拟程序TSC结合蒙特卡罗程序NUBEAM对使用中性束加热的EAST放电全过程进行数值模拟研究。分析了典型实验参数条件下的中性束的加热及电流驱动效果。讨论了不同背景等离子体密度对中性束加热及电流驱动效果的影响。模拟结果表明,中性束的注入使得背景等离子体温度有了较大幅度的提升,并能驱动出一定份额的非感应电流;适当降低背景等离子体密度有助于提高中性束的加热及电流驱动效率。

| Abstract: | Using 1.5D tokamak discharge simulation code(TSC) combined with NUBEAM code, the heating and beam-driven current of EAST-NBI in the next experimental campaign were studied. Under different background plasma density, the efficiency of EAST-NBI heating and current drive was discussed. Numerical simulation results show that the effect of EAST-NBI heating and current drive is quite good under the condition of the typical EAST experimental parameters. Proper lowering the background plasma density will improve NBI heating and current drive efficiency. |
