The FRIB linac will use superconducting resonators operating at a temperature of 2 K to accelerate ions to 200 MeV per nucleon. The linac requires 10⁴ quarter wave resonators (0.085 MHz, β=0.041 and 0.085) and 220 half wave resonators (322 MHz, β= 0.29 and 0.53), all made from sheet Nb. Production resonators are being fabricated by cavity vendors; the resonators are etched, rinsed, and tested in MSU's certification test facility. Cavity certification testing is done before the installation of the high-power input coupler and tuner. After certification and cryomodule assembly, the resonators are tested in the cryomodule before installation into the FRIB tunnel. The cryomodule test goals are to verify integrated operation of the resonators, RF couplers, tuners, RF controls, and superconducting solenoids. To date, 22 out of 46 cryomodules have been completed, and 18 have been certified. Cavity and cryomodule certification test results are presented in this paper.
