Because of its relevance for negative hydrogen ion sources, the change in secondary electron emission with the adsorption of Cs on Cu was studied. Properly prepared disks of oxygen free high conductivity (OFHC) copper yielded a maximum secondary electron emission dmax = 1.54+/- 3%. The deposition of » 0.5 monolayer of Cs resulted in dmax = 3.40+/-3%.
