N2 - The radio-frequency quadrupole (RFQ) at the Facility for Rare Isotope Beams (FRIB) is a 4-vane type cavity designed to accelerate heavy ion beams with charge states Q/A between 1/7 and 1/3 from 12 keV/u to 0.5 MeV/u. The RFQ was assembled in the FRIB tunnel in November 2016. Bead-pull measurements and tuning were performed with low RF power. The RFQ has been conditioned to 59 kW in August 2017, which is sufficient to accelerate the Key Performance Parameter (KPP) beams, Argon and Krypton. The RFQ has been successfully commissioned with KPP beams in CW regime in October 2017. 40Ar9+ and 86Kr17+ beams were accelerated by the FRIB RFQ in the CW regime to the designed energy of 0.5 MeV/u. With the multi-harmonic buncher operational, the FRIB RFQ commissioning has been completed with bunched beam in February 2018. The beam transmission efficiency through the RFQ was in good agreement with PARMTEQ simulation results. The detailed results from the FRIB RFQ tuning, high power conditioning and beam commissioning will be presented in this paper.
