A Material for Superconducting Radio-Frequency Cavity

Helmholtz-Zentrum Berlin für Materialien und Energie

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
