Test Cryostat Goals
• Individually test each spoke resonator with or without its associated solenoid or quadrupole
• Accommodate all spoke resonator designs with minimal cryostat alterations
• Apply input power using production couplers in multiple orientations (horizontal, vertical, 45° etc.)
• Allow testing at 2 K if necessary for diagnostics• Identical (or nearly so) test cryostats at Fermilab and
Argonne to allow identical test configurations

Conclusions
• Test cryostat– Design is nearly complete
– Some commercial parts on order
– Procurement on the main vessels will begin soon
• SSR-1 and SSR-2 cavities, tuner, and input coupler– SSR-1 cavity design complete and quotes for prototype assembly have
been received
– Tuner design in-process, prototype is planned
– Input power coupler prototype in fabrication, delivery expected late May or early June with testing to follow
– SSR-2 cavity design is in-process
• SSR-1 cryomodules– Design in-process
