    "abstract": "At the Holifield Radioactive Ion Beam Facility (HRIBF) at Oak Ridge National\nLaboratory (ORNL), molecular ions extracted from a positive ion source and\nsubsequently broken up in a charge exchange cell produce Radioactive Ion Beams\n(RIBs) with several hundred eV energy spread, preventing effective magnetic\nisobar separation. In order to perform magnetic isobar separation prior to\ncharge exchange, a multi-harmonic buncher and a 12 MHz RFQ (Radio-Frequency\nQuadrupole) is proposed to supplement the present 300 kV injection system for\nthe 25 MV tandem electrostatic accelerator. The RFQ will be mounted on a\nvariable high voltage platform to accelerate ions with masses from 10 to 150\namu.",
