	The Proton Improvement Plan II (PIP-II) that will be installed at Fermilab is the first U.S. accelerator project that will have significant contributions from international partners. CEA¿s scope covers the supply of the 650 MHz low-beta cryomodule sections with the cavities provided by LASA-INFN (Italy) and VECC-DAE (India) as well as the power couplers supplied by Fermilab. This scope includes the assembly of the 650 MHz low-beta cryomodules. Assembly studies have been conducted based on CEA experience acquired on previous projects as well as on the feedback of Fermilab on the assembly of the HB650 prototype cryomodule. This paper presents the organization of assembly phases from the cavity string in the clean room and the assembly of the cryostat to the preparation of the cryomodule before its shipment to Fermilab.

	Funding: Work supported by Fermi Research Alliance, LLC under Contract No. DEAC02- 07CH11359 with the United States Department of Energy, Office of Science, Office of High Energy Physics. This contribution reports the design of the production Single Spoke Resonator Type 1 Cryomodule (SSR1 CM) for the PIP-II project at Fermilab. The innovative design is based on a structure, the strongback, which supports the coldmass from the bottom, stays at room temperature during operations, and can slide longitudinally with respect to the vacuum vessel. The Fermilab style cryomodule developed for the prototype Single Spoke Resonator Type 1 (pSSR1), the prototype High Beta 650 MHz (pHB650), and preproduction Single Spoke Resonator Type 2 (ppSSR2) cryomodules is the baseline of the present design. The focus of this contribution is on the results of calculations and finite element analyses performed to optimize the critical components of the cryomodule: vacuum vessel, strongback, thermal shield, and magnetic shield.
