Role of magnetic flux expulsion to reach Q_{0}>3×10^{10} in superconducting rf cryomodules

When a superconducting radiofrequency cavity is cooled through its critical temperature, ambient magnetic flux can become “frozen in” to the superconductor, resulting in degradation of the quality factor. This is especially problematic in applications where quality factor is a cost driver, such as i...
