Progress Of Nb/Cu Technology With 1.5 GHz Cavities
The residual resistance of Nb/Cu cavities increases exponentially at high RF field. Two main possible causes have been investigated in detail: the hydrogen incorporated in the film during the sputtering process and the surface roughness induced by the substrate. The latter has been reduced with an o...
