Superconducting spoke resonators (SSR1 and SSR2) envisioned for Project X will be developed in Fermilab and operated at temperatures down to 2 K in continuous wave (CW) mode. Each spoke cavity will be tested individually in a cryostat that replicates conditions in the longer multi-cavity cryomodules. This test cryostat has all the features of the longer cryomodules – magnetic shielding, 80 K thermal shield, multi-layer insulation, support post, and input coupler [1]. Fermilab is in the processing of retrofitting the existing test cryostat which was originally designed for operation at 4.5 K. This paper describes the design of the conversion of the current test cryostat, flexible transfer lines, helium relief system and cryogenics interface.
