Glow discharge processing versus bakeout for aluminum storage ring vacuum chambers
Journal Article
·
· J. Vac. Sci. Technol.; (United States)
Experiments were carried out on laboratory and prototype scale systems in order to establish the feasibility of argon discharge processing the PEP storage ring aluminum vacuum chambers. Electron-induced desorption rates showed significant reductions following bakeout and/or argon glow discharge treatment (>10/sup 1/9 ions cm/sup -/1). Data are presented and discussed in relation to advantages and problems associated with: water removal, argon trapping and subsequent release, electron energy dependence, discharge distribution, and surface plasma chemical effects.
