Fermi National Accelerator Laboratory (Fermilab), operated by Fermi Research Alliance LLC (FRA) under prime contract with the U.S. Department of Energy (DOE), is preparing a solicitation for the work described herein. The purpose of this presolicitation notice is to make potential vendors aware that a formal solicitation may follow this notice.

The 325 MHz SSR2 (Single Spoke Resonator Type 2) cavity is a single spoke Superconducting Radio Frequency (SRF) resonator that will be used to accelerate the proton beam for the next generation accelerator complex at Fermilab and its development is done in the framework PIP-II project (Proton Improvement Plan II). A total of seven SSR2 cryomodules are planned to be integrated in the PIP-II linac superconducting section and each of cryomodule includes five SSR2 jacketed cavities, and three superconducting solenoids. Fermilab is working in partnership with IN2P3/IPNO (France) for the cavities design and fabrication.
