TI - Fabrication Experience of the Pre-Production PIP-II SSR2 Cavities at Fermilab J2 - Proc. of LINAC2022, Liverpool, UK, 28 August-02 September 2022 CY - Liverpool, UK T2 - International Linear Accelerator Conference T3 - 31 LA - english AB - The Proton Improvement Plan-II (PIP-II, [1]) linac will in- clude 35 Single Spoke Resonators type 2 (SSR2). A total of eight pre-production SSR2 jacketed cavities will be procured and five installed in the first pre-production cryomodule. The mechanical design of the jacketed cavity has been finalized and it will be presented in this paper along with fabrication and processing experience. The importance of interfaces, quality controls and procurement aspects in the design phase will be remarked as well as lessons learned during the fabri- cation process. Furthermore, development studies will be presented together with other design validation tests.
