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…

Microwave Microscope Studies of Trapped Vortex Dynamics in Superconductors
Chung-Yang Wang, Steven M. Anlage
Trapped vortices in superconductors introduce residual resistance in superconducting radio-frequency (SRF) cavities and disrupt the operation of superconducting quantum and digital…

Microscopic Examination of SRF-quality Nb Films through Local Nonlinear Microwave Response
Chung-Yang Wang, Carlota Pereira, Stewart Leith +2
The performance of superconducting radio-frequency (SRF) cavities is sometimes limited by local defects. To investigate the RF properties of these local defects, especially those t…
