The production of superconducting coatings for radio frequency (RF) cavities has been developed over several decades. It is widely accepted that for any further improvement in cavity RF performance, innovation is needed and one may have to turn to other forms of Nb and other superconducting materials. [...]

Impact of the Cu Substrate Surface Preparation on the Morphological, Superconductive and RF Properties of the Nb Superconductive Coatings
/ Pira, Cristian (INFN, Legnaro) ; Antoine, Claire (IRFU, Saclay) ; Chyhyrynets, Eduard (INFN, Legnaro) ; Jiang, Xin (Siegen U.) ; Katasevs, Aleksejs (Riga Tech. U.) ; Kaupuzs, Jevgenijs (Riga Tech.

Nowadays, one of the main issues of the superconducting thin film resonant cavities is the Cu surface preparation. A better understanding of the impact of copper surface preparation on the morphological, superconductive (SC) and RF properties of the coating, is mandatory in order to improve the performances of superconducting cavities by coating techniques.

In the investigations on the high gradient SRF cavities, the superconducting multilayer is a promising alternative. The predictions show that SIS
nanocomposite (Superconductor/Isolator/Superconductor) could improve
the efficiency limited by the bulk Nb itself used today for accelerating cavities. [...]
