| Description: |
Copper based Nb3Sn cavity is a promising candidate for next generation accelerator applications in the field of superconducting radio frequency SRF . It combines the excellent thermal conductivity of copper and the superior superconducting properties of Nb3Sn, and has the potential to greatly improve the performance of the SRF cavity. The electrochemical and thermal synthesis ETS bronze route is one of the proven methods to achieve Nb3Sn coating on copper. Its advantages are low cost, simple operation, suitable for complex cavity types and mass production. In this report, we have prepared a copper based Nb3Sn sample specifically for Quadrupole Resonator QPR testing. We provide a complete set of QPR sample preparation processes from copper electropolishing, Nb sputtering, electrodeposition and heat treatment to synthesize Nb3Sn. By optimizing the entire preparation process and key parameters, a new Cu based Nb3Sn QPR sample was successfully prepared and its RF properties have been characterized by QPR testing system at HZB |
