摘要
介绍了超导波荡器热负荷测试装置超高真空系统的设计、调试。通过离子泵、吸气剂泵以及系统低温冷凝面的联合抽气作用,使系统在常温下获得7.8×10-8Pa的真空度,在低温下能够获得1.7×10-8Pa的真空度,满足光源储存环真空系统1.3×10-7Pa的真空度要求。
Design and fabrication of the UHV system of the heat load testing device for SCU are introduced. The ion pump,NEG pump and cryogenic condensation surface are used to reduce the system pressure. The device can reach the pressure of 7. 8 × 10- 8Pa at the room temperature and 1. 7 × 10- 8Pa at the low temperature. The demand of the storage ring vacuum system for SSRF can be met.
