Characterization of etch pits found on a large-grain bulk niobium superconducting radio-frequency resonant cavity
The performance of superconducting radio-frequency (SRF) resonant cavities made of bulk niobium is limited by nonlinear localized effects. Surface analysis of regions of higher power dissipation is thus of intense interest. Such areas (referred to as “hotspots”) were identified in a large-grain sing...
