摘　　要：根据EAST-NBI大面积束引出系统的特点及装配要求,研究合理的装配方法。通过多种装配方法来消除装配中产生的误差,以到达最大误差小于0.05mm,真空接口漏率小于1×10 7Pa.L.s 1,冷却水管耐压1MPa,通过100kV的静电耐压测试,并进行了离子束引出,初步验证了引出系统装配的成功,支持兆瓦级强流离子源的研制。According to the characteristic of extraction system of EAST-NBI and the requests of assembly, the assembly methods were studied. Several methods were used to eliminate the assemble error, and the overall error is less than 0.05mm, the leak rate of vacuum interface is less than 1 x 10-7pa.L.s-1, and the resist pressure of cooling water pipe can reach 1MPa. Besides, the extraction system tested with 100kV static high voltage. It is meets the requirement of design of beam extraction system, and ensure the development of mage-watt high current ion source.
