摘要
在中性束注入器的研制中 ,大抽速低温泵的设计是其中非常重要的一部分。本文结合中性束注入器对真空系统的要求 ,介绍了中性束注入器真空系统的构成 ,并以布置于中性化室部位的低温泵为例 ,详细阐述了用于中性束注入系统的低温泵的结构设计以及抽速确定、冷凝面积确定等关键问题 ,成功设计了一套完全满足中性束注入系统对动态真空度要求的低温泵。
A novel cryopump has been successfully developed and constructed to meet the stringent requirements of the neutral beam injection (NBI) system on dynamic pressure. Various factors of the cryopump, such as its structure, its pumping speed and condensation areas, were discussed. The configuration, technical specifications and operation conditions of the neutral beam injection system were also discussed.
