Abstract:
The arrangement of RFQ vacuum system is briefly described. The vacuum level with assumed standard out-gassing rates of the RFQ major components is projected and compared with measurements. The permeation of water through Viton O-rings of the LCW manifold mounted inside the RFQ vacuum vessel is analyzed and compared with data taken at various ambient temperatures. The rate of hydrogen gas spill from the Ion
Source and LEBT into the RFQ vacuum space is also projected. Suggestions to improve RFQ vacuum system are presented and discussed.
