	Funding: Work supported by US DOE Cooperative Agreement DE-SC0000661 and Michigan State University Superconducting quarter-wave resonators and half-wave resonators are being prototyped and fabricated at Michigan State University (MSU) in effort to support the Facility for Rare Isotope Beams (FRIB) project. FRIB requires a 200 MeV per nucleon driver linac, operating 345 resonators at two frequencies (80.5 and 322 MHz) and four betas (0.041, 0.085, 0.29, and 0.53). FRIB cavity development work is underway, with the prototyping of all four resonators, including helium vessel design, stiffening strategy, and tuner interface. In addition, the acquisition strategy for FRIB resonators is being finalized, and the technology transfer program is being initiated. The status of the resonator production effort will be presented in this paper, including an overview of the acquisition strategy for FRIB.

	Funding: This material is based upon work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DE-SC0000661. Michigan State University is developing and testing quarter wave resonators for a superconducting linac which will be used to reaccelerate exotic ions to 3 MeV per nucleon or higher (ReA3). Eight quarter wave resonators with an optimum velocity of β = v/c = 0.085 and a resonant frequency of 80.5 MHz are required for the third cryomodule, which will complete the first stage of the reaccelerator linac. Approximately 100 additional β = 0.085 resonators of the same design will be required for the Facility for Rare Isotope Beams (FRIB). Results of Dewar testing to characterize the RF performance of the resonators will be presented in this paper.
