摘　　要：低温真空系统是NBI综合测试台(NBITF)的一个重要子系统,它为与束的生成和传输过程相关的各类实验提供真空环境支持。在介绍NBITF基本组成的基础上,重点阐述了其低温真空系统的冷凝屏结构与布局设计、气源特性和热负荷特性,并最终讨论确定了低温真空系统的冷量供给形式。实验结果表明,该低温真空系统的设计能满足NBITF的设计使用要求,并验证了EAST-NBI低温真空系统设计的正确性。Cryo-vacuum system is one of the most important subsystems of test facility for neutral beam injector（NBITF）,which supports experiments related to processes of beam generation and transportation in vacuum circumstance.After introducing the configuration of NBITF,main aspects of the cryo-vacuum system including the structure and layout in vacuum tank of its cryopanels,characteristics of its gas source and heat load were given.Cryogen supply modes were discussed and determined.Test results show that the design of the cryo-vacuum system can meet the requirements of NBITF and may reveal the validity of the design of EAST-NBI cryo-vacuum system .
