	The design of 5-cell elliptical 650 MHz β=0.9 cavities to accelerate H⁻ beam of 1 mA average current in the range 467-3000 MeV for the Project X Linac is currently under development at Fermilab. A new design of the Helium Vessel (HV) was developed for these cavities with the main goal of optimizing the frequency sensitivity df/dP by keeping the cavity stiffness reasonably small. We also present a design of the new lever tuner system. The HV in the new design is equipped with the tuner located at the end of the cavity instead of the initially proposed blade tuner located in the middle. We will present mechanical design results and ANSYS analyses for both the slow and fast tuners.

	Funding: Supported by FRA under DOE Contract DE-AC02-07CH11359 Project X is a proposed proton accelerator complex intended to support Fermilab’s role in intensity frontier research over the next several decades. It will replace the existing 40-year old Fermilab injector complex and add powerful new capabilities to support a large number of experiments in the energy range from 1 to 120 GeV. Fermilab is planning a program of research and development aimed at testing of critical components. This program, known as the Project X Injector Experiment (PXIE), is being undertaken as a major element of the ongoing Project X R&D program. PXIE contains two superconducting cavity cryomodules, one utilizing half-wave resonators (HWR), and the other, single spoke resonators (SSR). The first SSR cryomodule, known as SSR1 contains eight cavities and four solenoids in the following order: C–SC–CS–CC–SC–CS–C, as well as focusing and steering magnet elements. This paper describes the design of the SSR1 cryomodule and includes discussions of the system interfaces, vacuum vessel, magnetic and thermal shields, insulating and support systems, cavities, tuners, input couplers, focusing elements, and current leads.

Project X is a proposed proton accelerator complex intended to support Fermilab’s role in intensity frontier research over the next several decades.
