EAST 中性束注入电流驱动的数值模拟研究

摘要

Long pulse and high performance steady‐state operation is the main scientific mission of ex‐perimental advanced superconducting tokamak(EAST) .In order to achieve this objective ,high‐power auxiliary heating systems are essential .On the basis of the plasma equilibrium of previous EAST ex‐periments ,and according to EAST experimental demand ,the effects of plasma heating and current drive by neutral beam injection are simulated with different parameters of background plasma and neu‐tral beam ,such as different neutral beam power and beam energy etc .The simulation results are valu‐able for the study of neutral beam injection on EAST .%长脉冲高参数稳态运行是EAST的主要科学目标，因此大功率的辅助加热手段是必需的。文章基于EAST实验等离子体放电数据，针对EAST不同的中性束物理实验的需要，在不同的背景等离子体和中性束参数下模拟研究中性束注入的加热和电流驱动效果，包括不同的中性束注入功率和束能量等，模拟预测结果对开展EAST中性束注入实验研究具有参考意义。
