During the 2012 RHIC run cycle, the EBIS-based heavy ion preinjector provided U39+, Au32+ and Cu11+ ions for the RHIC physics program. The preinjector was operated for ~2.5 months continuously. Intensities delivered to the Booster synchrotron were ~109 U39+ ions/pulse, ~1.5·109 Au32+ ions/pulse, and ~6·109 Cu11+ ions/pulse, in ~20 μs pulses. When providing Au and Cu for asymmetric collisions in RHIC, both species were always available, with a switching time between species of 1 second. The performance and operational experience of this new preinjector will be presented.
