Surface Study Of Niobium For Superconducting Radio Frequency (Srf) Accelerators, Hui Tian Jan 2008

Surface Study Of Niobium For Superconducting Radio Frequency (Srf) Accelerators, Hui Tian

Dissertations, Theses, and Masters Projects

Niobium rf superconductivity is a near-surface phenomenon because of the shallow rf penetration depth. Accordingly, the performance of Nb SRF accelerator cavities is strongly impacted by the topmost few nanometers interior surface, especially as impacted by the final surface conditioning treatments.;Surface topography impacts performance through local loss of superconductivit caused by intrusion of the rf magnetic field, which is enhanced at sharp protrusions. "Sharpness" comprises both vertical and lateral aspects, requiring development a new characterization approach beyond the familiar roughness measurements (Ra, Rz), which view only the vertical component. Stylus profilomety and atomic force microscopy traces view surface topography from …
