A Comparison of Outgassing Measurements for Three Vacuum Chamber Materials
Conference
·
OSTI ID:816490
Outgassing measurements of three UHV materials (304 Stainless Steel (SS), 316L SS and 6061T-6 aluminum) were made using the conductance and accumulation techniques as given in the AVS Recommended Practice for Outgassing Measurements [ ]. Measurement results indicate good agreement between the two techniques. This study was undertaken to help determine the vacuum limitations of the photoelectron guns used at Jefferson Lab and to aid in the choice of vacuum chamber materials that will be used in the construction of future photoelectron guns. The outgassing rate measured for all of the chamber materials, regardless of technique, was about 1 X 10{sup -12} Torr{sup -}l/s{sup -}cm{sup 2}.
