Description
In this contribution, we present recent progress in the development of Nb₃Sn-coated superconducting radio-frequency (SRF) cavities for continuous-wave, high-gradient applications using the vapor-diffusion coating technique. Several cavities with different geometries and sizes have been successfully coated with Nb₃Sn, including one that achieved an unprecedented peak magnetic field of about 105 mT. The coated cavities support a variety of applications, including the development of a low-beta Nb3Sn cavity for ion acceleration at ATLAS and initiatives aimed at the industrialization of SRF cavity fabrication at IARC. The lessons learned and technical challenges during the coating process will be discussed.
