| Abstract: | 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. |
