摘　　要：中性束注入(neutral beam injection,NBI)是加热等离子体、改善等离子体约束性能的一种有效途径。文章对先进超导托卡马克实验装置(Experimental Advanced Superconducting Tokamak,EAST)高功率NBI下H模放电进行了初步实验研究,从等离子体密度、等离子体储能、温度、辐射、D_α信号的爆发等方面分析了等离子体在NBI下进入H模放电的性能改善,同时利用NUBEAM程序对高功率NBI注入能量输运方面进行了初步分析。Neutral beam injection(NBI) can effectively enhance the plasma heating and improve the plasma confinement.In this paper,the preliminary experimental study on Experimental Advanced Superconducting Tokamak(EAST) H-mode discharge with NBI high power injection is conducted and the improvement of the performance of plasma with NBI injection is explored from the perspectives of plasma density,plasma stored energy, plasma temperature,plasma radiation and D α signal breakout.And the NBI energy transport is also analyzed with the NUBEAM code.
