  5. Summary: Air baked copper lab measurement Heating copper in air prior to in-situ bakeout is a simple method to produce large uniform surfaces with reduced SE emission. Reduction in SEY is due to formation of 50-nm layer of cuprous oxide, Cu2O (dmax~1.2), whose SEY is lower than SEY of Cu (dmax~1.3), plus surface roughening Air baked copper, Frank Zimmermann, ECL2, 1 March 2007
