Description
As FCC-ee reconfigures to reach higher and higher energies, many 800 MHz SRF cavity cryomodules are planned for installation in the tunnel. In this presentation, we discuss some R&D activities at Fermilab related to these cryomodules. We present relevant R&D towards achieving high Q0 in cavities in this frequency range and at operating gradients relevant for the FCC-ee specification, including treatment and testing of 800 MHz cavities built by Jefferson Lab. We also discuss cryomodule design, particularly in relation to PIP-II cryomodules with similar frequency. Finally, we discuss recent relevant SRF cryomodule production experience at Fermilab.
