【摘要】 等离子体物理研究所计划研制中性束注入器(NBI),为EAST等离子体提供有效的加热和无感电流驱动,进行相关物理实验研究。该NBI的基本组成包括强流离子源、由中性化室、偏转磁体、功率测量靶、离子吞食器、主真空室等构成的束线本体、电源系统、控制系统等,其主要设计指标为:束能量50～80 keV、注入束总功率2～4 WM、束脉宽10～100 s。介绍了作为其关键组成部分的离子源、偏转磁体、功率测量靶、等的设计方案与基本结构,该NBI的研制是一个复杂而艰巨的任务,现已对其关键部件进行了预研,预计可在四年内完成。更多还原

【Abstract】 A neutral beam injector(NBI) was considered to be developed in ASIPP to support the EAST physical research.It is mainly used for the plasma heating and current driving.The NBI system mainly consists of high current ion source, neutralizer,bending magnet,calorimeter,ion dump,vacuum vessel and power supply system,control system.It can provides a neutral beam with beam energy of 50～80 keV,beam power of 2～4 WM,and beam pulse of 10～100 s.The development of NBI system is a complicated and difficult mission,and the key components design such as ion sources,bending magnet, calorimeter,etc are ongoing.The development of the NBI system will be completed in 4 years.更多还原
