中文摘要：

高能中性束注入（Neutral beam injection，NBI）是核聚变装置托卡马克采用的芯部辅助加热和非感应电流驱动主要手段之一。本文介绍了国家大科学工程全超导托卡马克实验装置（Experimental advanced superconducting tokamak，EAST）上的高能NBI加热方案及注入器的工程要求，并讨论了中性束在EAST等离子体中的传输等相关问题。

英文摘要：

High energetic neutral particle beam injection （NBI） is one of most important methods for core auxiliary heating and non-inductive current drive of plasma in nuclear fusion devices. Based on the requirements of present National Science Mission——EAST （experimental advanced superconducting tokamak） system, an NBI project with delivery power up to 8 MW was proposed and the related consideration both on engineering and physics was on the way. The project of the EAST NBI is presented in this paper, including requirement of physics and engineering, esrimarion of the neutral beam transmission in the EAST plasma, etc.
