SSR1 Cryomodule Design for PXIE

Fermilab is in the process of designing a Project X Injector Experiment (PXIE), a CW linac, to validate the Project X concept, reduce technical risks, and obtain experience in the design and operation of a superconducting proton linac. The over-all facility will include an ion source, low and medium-energy beam transport sec-tions, an RF quadrupole, and two superconducting cavity cryomodules. One will contain eight half-wave resonators operating at 162.5 MHz and eight superconduct-ing solenoids. The second will contain eight single spoke resonators (SSR1) oper-ating at 325 MHz and four superconducting solenoids. The design of the cryomod-ule being developed to house the 325 MHz single spoke resonators and all related systems and services is described here....
