The Role of Magnetic Flux Expulsion to Reach Q0>3x10^10 in SRF Cryomodules
S. Posen, G. Wu, E. Harms +7
When a superconducting radiofrequency cavity is cooled through its critical temperature, ambient magnetic flux can become "frozen in" to the superconductor, resulting in degradatio…

The Effect of Mechanical Cold Work on the Magnetic Flux Expulsion of Niobium
S. Posen, S. K. Chandrasekaran, A. C. Crawford +5
Expulsion of ambient flux has been shown to be crucial to obtain high quality factors in bulk niobium SRF cavities. However, there remain many questions as to what properties of th…
