Abstract |
The superconducting driver linac for the Facility for Rare Isotope Beams (FRIB) requires the production of 46 cryomodules. Design is complete on all six cryomodule types which utilize four superconducting radio frequency (SRF) cavity designs and superconducting solenoids. The FRIB cryomodules utilize an innovative bottom up approach to achieve alignment tolerance and simplify production assembly. The cryomodule testing includes qualification of the resonator performance, fundamental power couplers, tuners, and cryogenic systems. FRIB beam commissioning has been performed on 15 cryomodules in the FRIB and validates the FRIB cryomodule bottom up assembly and alignment method. This paper will report the FRIB cryomodule design, performance, and the alignment results and their impact on beam commissioning.
