摘要:Desorption yields obtained from a KBr(001) surface irradiated by 1.5–3-keV electrons have been measured via layer-by-layer mode removal. The yields are obtained from the inverse electron fluences required to remove the monolayer, which are measured from the specular intensit...

摘要:We have developed a new non-evaporable getter (NEG) coating using titanium and palladium vacuum sublimation. The inner wall of the test chamber was coated with a 1-µm Ti thin film using the Ti sublimation pumps under a vacuum of 6.5×10 Pa (Ti-coated chamber). This chamber wa...
