摘要
降低中性束注入器低温冷凝泵的LHe消耗率,是进行低温冷凝泵设计时应考虑的核心问题之一。通过对NBI低温冷凝泵的LHe杜瓦进行热力分析,确定了影响杜瓦内LHe蒸发率的关键参数。探讨了降低LHe蒸发率的措施,依此确定了在工程设计中为达到减小LHe蒸发率、提高泵运行经济性可采用的结构形式。
It is a key issue to decrease the LHe consumption rate of cryocondensation pump of NBI. Thermal analysis for LHe Dewar was made. The main parameters that affect the LHe consumption rate of the Dewar were obtained. The measures on how to decrease the LHe consumption rate were discussed. Several useful inner structuretypes for large LHe Dewar of NBI cryocondensation pump were suggested.
