摘要：

中性束注入是等离子体加热和电流驱动的重要方式之一，对EAST中性束注入的精确模拟对未来物理实验至关重要。采用ONETWO和NUBEAM程序模拟4MW、80keV中性束同向注入，不同的等离子体密度剖面导致不同的电子和离子加热、穿透功率损失、束驱动电流以及中子发射等。等离子体密度在以上的物理参数的演化中起着重要的作用。对EAST两种密度方案下中性束注入的效果进行了分析和讨论，并对未来中性束实验提供了一些预言性的建议和方案。

Abstract:

Accurate simulations of neutral beam injection (NBI) in the experimental advanced superconducting tokamak (EAST) are vitally important for the analysis of future experiment since NBI is an important plasma heating and current drive tool. The different plasma density profiles of EAST can lead to different target electron and ion heating, shine-through power loss, beam-driven current and neutron emission with 4MW and 80keV beam co-injection using ONETWO and NUBEAM codes. The plasma density plays an important role in the evolution of the above physical parameters. The effects of NBI due to two density cases on EAST are discussed and some advices are submitted for the future physical experiments.

Key words: NBI, ONETWO code, NUBEAM code, EAST
