Description
Nb$_3$Sn SRF cavities have the potential to reduce operating and capital costs for SRF accelerators. A first-of-its-kind Nb$_3$Sn 2-cavity CEBAF-type cryomodule has been assembled and tested. The cryomodule contains two 5-cell cavities: one coated and qualified by the team at Jefferson Lab and the other by the team at Fermilab. The cryomodule, assembled and tested at Jefferson Lab, achieved 10 MV accelerating voltage. This talk highlights steps during this development, including cavity preparation and qualification, mitigations to avoid cavity performance degradation during string and cryomodule assembly, and cryomodule testing.
