On the theoretical RF field limits of multilayer coating structures of superconducting resonator cavities
arXiv:1309.5626
Abstract
This Comment addresses theoretical field limits for superconducting-insulating (S-I) thin films multilayers discussed by S. Posen, G. Catelani, M. Liepe, J. Sethna, and M. Transtrum [1]. It is shown that their criticism of the SIS multilayer approach [2] to reduce vortex dissipation in superconducting RF resonator cavities is unsubstantiated
