| Title | Performance of the Cornell conduction-cooled Nb3Sn cavity cryomodule (C4M) |

| Abstract | Recent improvements in Nb3Sn cavity and commercial cryocooler performance have made the fabrication of conduction-cooled cryomodules for SRF cavities feasible, which drastically expands SRF applications to medical imaging, water purification, and security. Cornell has developed a turn-key, conduction-cooled cryomodule to operate a 1.3 GHz Nb3Sn SRF cavity by optimizing the cooling output of two commercial cryocoolers. The cryomodule, cavity, and RF input coupler have been designed for very high CW beam current operation (>100 mA) and high RF power (100 – 200 kW CW RF). We present the design, optimization, and assembly process of this conduction-cooled cryomodule as well as performance during initial cooldown tests and low power RF testing. |
