Outgassing properties and surface profiles of titanium materials have been investigated in this paper. Titanium materials showed excellent outgassing rates below 10<sup>-12</sup> Pams<sup>-1</sup> after baking process. These values are two orders of magnitude smaller than that for standard vacuum materials under the same pre-baking condition. Outgassing(More)
