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…
Dissipation by surface states in superconducting RF cavities
Sean Deyo, Michelle Kelley, Nathan Sitaraman +5
Recent experiments on superconducting cavities have found that under large radio-frequency (RF) electromagnetic fields the quality factor can improve with increasing field amplitud…
Analysis of Magnetic Vortex Dissipation in Sn-Segregated Boundaries in NbSn Superconducting RF Cavities
Jared Carlson, Alden Pack, Mark K. Transtrum +9
We study mechanisms of vortex nucleation in NbSn Superconducting RF (SRF) cavities using a combination of experimental, theoretical, and computational methods. Scanning transmi…
Vortex dynamics and losses due to pinning: Dissipation from trapped magnetic flux in resonant superconducting radio-frequency cavities
Danilo B. Liarte, Daniel Hall, Peter N. Koufalis +4
We use a model of vortex dynamics and collective weak pinning theory to study the residual dissipation due to trapped magnetic flux in a dirty superconductor. Using simple estimate…
Theoretical estimates of maximum fields in superconducting resonant radio frequency cavities: Stability theory, disorder, and laminates
Danilo B. Liarte, Sam Posen, Mark K. Transtrum +3
Theoretical limits to the performance of superconductors in high magnetic fields parallel to their surfaces are of key relevance to current and future accelerating cavities, especi…
Ginzburg-Landau theory of the superheating field anisotropy of layered superconductors
Danilo B. Liarte, Mark K. Transtrum, James P. Sethna
We investigate the effects of material anisotropy on the superheating field of layered superconductors. We provide an intuitive argument both for the existence of a superheating fi…
