A Material for Superconducting Radio-Frequency Cavity

The photomontage shows a sample of solid, pure niobium before coating (left), and coated with a thin layer of Nb3Sn (right).

At present, niobium is the material of choice for constructing superconducting radio-frequency cavity resonators. These will be used in projects at the HZB such as bERLinPro and BESSY-VSR, but also for free-electron lasers such as the XFEL and LCLS-II. However, a coating of niobium-tin (Nb3Sn) could lead to co
