Description
Mass production of 1.3 GHz high-Q superconducting cavities for the Shanghai High repetition rate XFEL and extreme light facility (SHINE) has now been successfully carried out. Both high temperature nitrogen doping (N-doping) recipe and mild temperature (Mid-T) baking recipe have been adopted to achieve high-Q performance. The production are shared by five companies to provide cavities at different stages. In the paper, experience with high purity niobium materials and 1.3 GHz high-Q cavities for SHINE will be present and main performance including mechanical properties and Q0-Eacc curve will be reported. The lessons we learned during production will be discussed. Cavities performance from vertical test to horizontal test will be reported, too.
