This work will provide an insight into the CERN R&D programme on superconducting thin films. The aim is to find coating techniques and/or new materials with enhanced RF performance applicable to SRF cavities. The main lines of research at CERN consist of Nb on Cu technology, historically used in our accelerators, and A15 on Cu, to find new superconducting materials with potential application...
In this work, an alternative method to compute the effect of losses on superconductors based on the Lossy Transmission Line Theory is introduced rigorously. In contrast to the application of the well-known perturbative methods at the dielectric-superconductor interface to obtain the equivalent surface currents, this new approach lies in analyzing the decaying propagative waves along the...
