While unbounded collective human mind continues to push beyond the boundaries in uncovering myriad mysteries of our universe, highly performing particle accelerators become indispensable tool to conduct successful experiments to shed light on such fundamental scientific inquires. On the path towards more efficient and sustainable particle accelerators, overcoming performance bottleneck of the...

33. Microstructural characterization of advanced superconducting materials for different components of the CERN Future Circular Collider (FCC-hh)

The microstructural characterization represents an essential aspect for helping the enhancement of the material superconducting properties. Within the huge CERN project related to the realization of the FCC-hh, we focused on the microstructural analysis of superconducting materials envisioned as suitable candidates for some of its fundamental components: Nb₃Sn for the bending...

41. Development of a Station at the CERN Central Cryogenic Laboratory for the Measurement of the Critical Temperature of Superconducting Thin Films Deposited on Copper

The FCC Study is an international collaboration established, in the search for physics beyond the Standard Model, to investigate the feasibility of a new circular collider having LHC as main injector. To this end, the development of ad-hoc SRF cavities represents a major challenge, for which superconducting (SC) film coated copper cavities are one of the pursuable solutions. Among the several...

43. Investigation of the influence of copper surface preparation methods on the srf performance of bulk niobium films

The niobium-coated copper cavities are interesting candidates for replacing bulk niobium cavities in future facilities (e.g. FCC). Such cavities, ideally, should overcome some accelerator design problems related to bulk Nb cavities. However, Nb/Cu films tend to show more extreme “Q-slope” effect, and have other disadvantages compared to bulk-Nb cavities, which currently limit their application...
