A Three-Fluid Model of Dissipation at Surfaces in Superconducting Radiofrequency Cavities
Matthias Liepe Michelle M. Kelley, Sean Deyo, Nathan Sitaraman +4
Experiments on superconducting cavities have found that under large RF fields the quality factor can improve with increasing field amplitude, a so-called ``anti-Q slope.'' We numer…

Microscopic Investigation of rf Vortex Nucleation in Nb3Sn Films Using a Near-Field Magnetic Microwave Microscope
Chung-Yang Wang, Zeming Sun, Thomas Oseroff +2
We use a near-field magnetic microwave microscope to investigate and compare rf vortex nucleation in two superconducting radio-frequency (SRF)-quality Nb3Sn films fabricated by dif…
