Effect of inhomogeneous surface disorder on the superheating field of superconducting RF cavities

Recent advances in the surface treatments of niobium superconducting radio-frequency (SRF) cavities have led to substantially increased Q factors and a maximum surface field. This poses theoretical challenges to identify the mechanisms responsible for such performance enhancements. We report theoret...
