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…

Study of Antisite Defects in NbSn: Phase Diagram and Impact on Superconductivity
Nathan S. Sitaraman, Jared Carlson, Alden R. Pack +4
Antisite defects play a critical role in NbSn superconducting radio frequency (SRF) cavity physics. Such defects are the primary form of disorder in NbSn, and are responsib…

Role of surface defects and material inhomogeneities for vortex nucleation in superconductors within time-dependent Ginzburg-Landau theory in 2 and 3 dimensions
Alden R. Pack, Jared Carlson, Spencer Wadsworth +1
We use Time-Dependent Ginzburg-Landau theory to study the nucleation of vortices in type II superconductors in the presence of both geometric and material inhomogeneities. The supe…
