Vacuum system for UVSOR storage ring
- 1. Institute for Molecular Science, Okazaki 444 (Japan)
Description
The vacuum system of the UVSOR electron storage ring is made of stainless steel and evacuated by sputter ion pumps, titanium sublimation pumps and built-in pumps. The pressure of 10-9 Torr is required to maintain long lifetime of the beam. The average base pressure was on the order of 10-8 Torr and the e-folding lifetime was only several min in the early days. Following the improvement of the pressure in the past three years routine operation on the ring, it became about 2 hr at the beam current of 100 mA. The improvement is mainly due to the cleaning effect of synchrotron light which desorbs molecules of gases from the surface of the beam pipe. This report describes the performance of the vacuum system and aging effect of the synchrotron light
