Project X is based on a 3 GeV CW superconducting linac and is currently in the R&D phase awaiting CD-0 approval. The low-energy section of the Project X H{sup -} linac includes three types of super-conducting single spoke cavities operating at 325 MHz. SSR0 (18 cavities), SSR1 (20 cavities) and SSR2 (44 cavities) have a geometrical beta of {beta} = 0.11, 0.21 and 0.4 respectively. Single spoke cavities were selected for the linac in virtue of their higher r/Q values compared to standard Half Wave Resonator. Quarter Wave Resonators were not considered for such a high frequency. In this paper we present the decisions and analyses that lead to the final design of SSR0. Electro-magnetic and mechanical finite element analyses were performed with the purpose of optimizing the electro-magnetic design, minimizing frequency shifts due to helium bath pressure fluctuations and providing a pressure rating for the resonators that allow their use in the cryomodules.
