Investigating the Superconducting Properties and Surface Morphology of Sputtered Nb Films on Cu Due to Laser Treatment / Turner, Daniel Andrew (Lancaster U.) ; Malyshev, O B (Cockcroft Inst. Accel. Sci. Tech.) ; Burt, G (Lancaster U.) ; Seiler, E (Bratislava, Inst. Phys.) ; Ries, R (Bratislava, Inst. Phys.) ; Medvids, A (Riga Tech. U.) ; Onufrijevs, P (Riga Tech. U.) ; Valizadeh, R (Cockcroft Inst. Accel. Sci. Tech.) ; Sublet, A (CERN) ; Pira, C (INFN, Legnaro) et al.
Bulk niobium is currently the material of choice for superconducting radio frequency (SRF) cavities and is a well matured process. However, it is possible that SRF cavities could be further improved beyond bulk Nb by sputtering thin Nb films onto Cu cavities. [...]

U.) ; Pira, Cristian (INFN, Legnaro) et al.
Superconducting (SC) thin film coatings on Cu substrates are already widely used as an alternative to bulk Nb SRF structures. Using Cu allows improved thermal stability compared to Nb due to having a greater thermal conductivity. [...]

An international collaboration of research teams from CEA (France), CERN (Switzerland), INFN/LNL (Italy), HZB and USI (Germany), IEE (Slovakia), RTU (Latvia) and STFC/DL (UK), are working together on better understanding of how to improve the properties of superconducting thin films (ScTF) for RF cavities. The collaboration has been formed as WP15 in the H2020 ARIES project funded by EC. [...]

U.) ; Onufrijevs, Pavels (Riga Tech. U.) et al.
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. U.) ; Kugeler, Oliver (Helmholtz-Zentrum, Berlin) ; Leith, Stewart (Siegen U.) ; Malyshev, Oleg (Daresbury) ; Medvids, Arturs (Riga Tech. U.) et al.
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.
